Maintenance Tasks

Today has included a number of little maintenance tasks. I’m glad they got done and in the big scheme they really aren’t much, but all the research and subsequent installation work seemed to take a bit of time. Thus far today I have…

…gotten an oil and transmission fluid change in my car.
…purchased replaced light bulbs (stop indicator and license plate) in the car.
…acquired and replaced rough service garage door opener bulbs.
…acquired and installed a Roku 2 XS for use while on the trainer.
…chosen and purchased snow tires (w/ wheels and TPMS sensors) for Danielle’s Mazda 3.

Now to relax a bit.

2012 Iceman Cometh Challenge

This past weekend was the 2012 Iceman Cometh Challenge, a mountain bike race which runs from Kalkaska to Traverse City; a distance of just over 30 miles. I really like this race, so once again Danielle and I made the trek up north and I set out on a cold morning with about 4000 other people to see how quickly I could complete the ride.

The morning started out dark and cold, with my brushing 1/4″ of snow off the car before meeting Jeremy before dark at the Rasho Road parking area so he could get a ride to Kalkaska and have his truck waiting for him near the finish. The sun rose as we drove in a line of bike-laden cars to Kalkaska, got ready in the Kaliseum parking lot, I made my way to the start line, then at 9:33am it was my time to race.

As usual I started out slow, not pushing myself as hard as I should have for a good race pace, but I was having fun. I pushed more as the kilometer markers ticked down, and the closer we got to the finish line at Timber Ridge the more snow appeared on the ground, the wetter and greasier the trails became, and the faster I felt like I was riding. Faster everywhere except for on some new single track that was built in weeks before the race, designed specifically to avoid some logging-damaged sand roads.

Early on a woman swerved harshly in front of me, and later on I choose a line to pass which lead around a curve into deep sand and walked my first hill of the year. I also walked the notorious Anita’s Hill near the end, and once I got near the top I was glad I did. I was walking up it at the same speed as many were riding it, and the trail near the top was quite chewed up. By walking what’s essentially a rooty stairway at the right side I stayed out of people’s way and had a slight change of pace. The only other walking point was early on where someone fell over in front of me while in some sand, forcing me to stop, so I opted to walk up the next hill instead of trying to get going in soft sand.

A few miles in there was a bit of excitement as a panicked deer ran between some riders about 30′ in front of me and another ran parallel to us for a few hundred feet. I yelled at it, scared that it’d try to cut between us as well and hit someone. Fortunately it veered off the other direction and there were no problems. At another point someone riding along called out a notorious root located around a sharp corner, which was quite welcome as being parallel with the trail and around a blind corner it could easily cause a crash. By giving a heads up riders can keep an eye out for it and allow the notoriously heavy Iceman traffic to keep moving.

Before too long I was crossing the finish line and it all was over, a quite uneventful race. I ended up finishing with an official time of 2:26:42, putting me at 16th of 61 in the Men 34 category and 1269th out of 3881 finishers (3498 men). This is about eight minutes slower than last year’s time, but with a much more difficult trail (due to the extra single track and weather) I’m content with the time. I was definitely not nearly as worn out after this year’s race as I was last year, though. While I was tired of riding in wet conditions I could easily have done another 20-30 miles at a smilar pace.

While the weather was cool and damp which led to some greasy trails, spinning rear wheels on uphills, and drivetrain issues for many, the moisture kept much of the sand well-packed and allowed for some parts of the trail to be very fast. As I approached Traverse City there was quite a bit of snow hanging on the trees, leading some parts of the trail to feel like riding through a snowy, wintery tunnels. It was incredibly beautiful and a wonderful feeling.

If any of you are interested in more detailed results my plate number was 1266 and detailed results can be found here. I also have a copy of my Garmin data from the race on Strava and visible here on Garmin Connect and here on Strava.

The photo above (from HaysPhotography) shows me about 1:23 into the race, about a mile east of Williamsburg Road, which is a very popular spectator location and generally considered to be the point after which the difficult climbing in the race begins. Danielle drove to Williamsburg Road to see me pass, and it was quite a nice treat to see her along the side, cheering me on. Here is another photo of me, this one taken by Jack Kunnenn somewhere near the finish line, but as I didn’t pay for it I won’t be hosting a copy myself. There’ll likely be other photos online later, but for now that was all I could find.

Also, here is a video of this year’s course from someone who started ten waves (almost half an hour) in front of me and finished in just about two hours, so by the end of the video he is almost an hour ahead of me.

Now it’s time to clean off my bike. As can be seen here my drivetrain has a nice, thin layer of crud packed into it. Similar dirt caused drivetrain issues for many others, but thankfully my cobbled together 1×9 setup held up nicely with only a bit of noise when in the largest cog on the cassette.

Addison Oaks Lake George Entrance

This afternoon while hiking at Addison Oaks to collect some map data I saw that the new non-motorized park entrance from Lake George road is complete. This is a gap in the fence with both a triangular gate to allow equestrians but help keep motorized vehicles out, and a swinging gate allowing it to be locked shut. The swinging gate is latched shut with a chain that slips through a latch.

The latching mechanism is a bit awkward because of how the installers positioned the wooden posts in relation to the chain link fence. When I first got to the gate the chain was looped around the wood post, as seen above. This can be done by someone standing inside the park, but once outside it’s very difficult to get the chain wrapped around the wood post. Looping the chain around a metal post, as seen here works better from the outside of the park, but clearly isn’t the intended design. Regardless, it still holds the gate securely shut.

Having to close a gate behind one’s self is a bit abnormal for cycling in this area. From what I’ve read it seems common out west and in Europe, but I’m not aware of any legal trails in Michigan that have gates which one needs to open and close in order to traverse.

I’m really happy about this entrance, as it’ll allow one to enter Addison Oaks from the west. The other (and larger) part of the project that installed this entrance is a path connecting through Addison Oaks, along some boardwalks, to Addison Oaks East, leading to Oakland Township’s Cranberry Lake Park. This adds a nice, safe, easy option for dirt road riding in this area.

Here’s two more photos of the gate: gate open and the latching mechanism, with the chain looped around a metal post.

Muddy Trails Enhance OpenStreetMap Data

Part of my map making workflow that uses OpenStreetMap (OSM) data requires updating the existing data set to be as accurately as possible before exporting the data. The data that I originally loaded into OpenStreetMap for River Bends was based on GPS surveying that I did not long after some new trails were built. Thus, the (prone to error) GPS data was the most accurate data available.

When updating OSM data, one is explicitly permitted to trace Bing imagery to enhance maps. Earlier today while poking around in JOSM (which adds Bing data as a tile so it can be traced) I noticed that the latest imagery for River Bends was taken on March 11, 2012 and most of the recently built single track is now visible. Because of the particularly wet spring here in Southeast Michigan many of the trails were muddy while these photos were taken, resulting in the trails being visible dark marks on the traceable photos.

The image above demonstrates this, showing the imagery date, current OSM data (red dashed line), and the wide/dark lines are the trails themselves. By adjusting the routes to match the imagery I can radically clarify the OSM data, validating and refining routes. River Bends is due for a map update soon after some new trail construction is complete, so this means that the next map of there will be much, much more detailed and accurate. Thanks in large part to a wet, muddy March.

Mountain Bike Trespassing in Michigan

I’ve recently been involved in some conversations about riding bikes on trails which connect to designated park-owned mountain bike trails, but lead off of park property on to other lands. As a result I decided to research trespassing laws in Michigan, specifically the Natural Resources and Environmental Protection Act (Act 451 of 1994), Part 731: Recreational Trespass. In particular, 324.73102 states:

(1) Except as provided in subsection (4), a person shall not enter or remain upon the property of another person, other than farm property or a wooded area connected to farm property, to engage in any recreational activity or trapping on that property without the consent of the owner or his or her lessee or agent, if either of the following circumstances exists:

(a) The property is fenced or enclosed and is maintained in such a manner as to exclude intruders.

(b) The property is posted in a conspicuous manner against entry. The minimum letter height on the posting signs shall be 1 inch. Each posting sign shall be not less than 50 square inches, and the signs shall be spaced to enable a person to observe not less than 1 sign at any point of entry upon the property.

Since we all live in a land where everything which is not prohibited is permitted, I read this as an assurance that entering property of unknown ownership, for any recreational purpose is permitted so long as one does not cross a fence designed to keep people out or pass a sign prohibiting entry. While on this property one is not permitted to modify the property, as per 324.73109 there are penalties for property damage.

Therefore, I take this all to mean that riding from trails on known park property to trails on unknown, unposted property is wholly permitted, so long as one does not modify the land (read: build new trails or other stuff) or cause damage.

UPDATE: As Cefai noted in the comments below, this is consistent with section 750.552 of the Michigan Penal Code which states:

(1) A person shall not do any of the following:

(a) Enter the lands or premises of another without lawful authority after having been forbidden so to do by the owner or occupant or the agent of the owner or occupant.

(b) Remain without lawful authority on the land or premises of another after being notified to depart by the owner or occupant or the agent of the owner or occupant.

(c) Enter or remain without lawful authority on fenced or posted farm property of another person without the consent of the owner or his or her lessee or agent. A request to leave the premises is not a necessary element for a violation of this subdivision. This subdivision does not apply to a person who is in the process of attempting, by the most direct route, to contact the owner or his or her lessee or agent to request consent.

Thus, unless you’ve been told not to enter the property or to leave, you may do so, unless it’s a posted farm. Then you may only enter to seek permission to remain.

FOX F29 RLC Seal and Oil Replacement

Today I did my first seal and oil replacement on a FOX fork. I’d watched Erik do his before, but it was a few years back so I didn’t remember much about the process. While I took my time this was easier than I’d expected, and almost everything went smoothly.

To do this work I’d purchased a bottle of 10 weight (Green) Suspension Fluid, a SKF low friction seal kit, 5mL packet of Float Fluid, and a seal driver tool to help seat the seals. I’d also picked up some graduated cylinders for measuring the oil, and a friend made me a very nice tool for removing the top caps. These parts all worked out very well, and following FOX’s documentation for seal and oil replacement, oil volumes, and use of the seal driver I had no problems getting everything together.

The greatest difficulty was removing the old seals, but a little persistance on the first one paid off, and then using this as a model I was able to get the second out much more easily. There were a few small things learned that’ll make the work easier next time, including:

· The foam rings take very little time to soak up oil when pre-soaking them.
· Once the damper is in place, there’s not much room below the damper cap for adding oil unless air is let out of the spring side to collapse the fork. After this there’s a plenty large space to pour in the oil.
· Tilting the fork while adding oil to the damper side makes things slightly easier.
· The nuts on the bottom of each fork leg are identical.
· Crush washers stick solidly to the nuts on the fork legs and blend in. The replacement ones, before being crushed, fit much more easily.
· Suspension oil tends to get all over the place. Even with wiping the entire fork down there is still an oily residue which leaves a nice sheen, especially if the fork is a bit weathered and becoming matte.

I received this fork when I purchased this bike in December of 2009. Since that time I’d put around 5000 miles on the bike, but never rebuilt the fork nor replaced the oil. While I’d been particular about keeping the stanchions clean I was not shy about riding it in poor conditions. FOX recommends changing the oil every 30 hours on forks. I definitely exceeded this, yet the oil in the fork was still quite clear, the foam rings mostly clean and oil-saturated, the stanchions unmarred, and there was still a fair amount of oil in the various chambers. The only way the stanchions look not-new is some fading on the portion which was exposed to sunlight. Here is a photo of the disassembled uppers and lowers showing nothing more than a slight bit of fading.

Hopefully after the work I’ve done the fork continues to work as reliably as it had for these past years.

Second Small Block Eight Sidewall Failure

While getting ready to head out on a lunch time ride I noticed that the sidewall of a recently-installed tire on my Salsa El Mariachi had a bubble in it. This is the same failure mode that I experienced back on April 1st when out at Addison Oaks with Erik and Jeremy. The sidewall tears away from the bead, and the tube bubbles out the side. Thankfully this time it didn’t burst before I caught it.

Both of these tires were purchased from a Kenda rep back in early 2010 when on a trip to Ray’s, and I guess it was time for them to go. The tire has been replaced with a Kenda Slant Six that I picked up last year, which makes for a nice (albeit slightly knobbier) rear tire which will hopefully hold up for a while.

I guess it’s good that this didn’t happen (or result in a full failure) while riding Stony Creek last night. Now, to reschedule today’s riding until after work…

Custom 26mm FOX 32mm Fork Top Cap Socket

I need to rebuild the FOX F29 RLC fork on my Titus, so I ordered the supplies to rebuild the fork, but found that I’d need a socket that has had the face ground flat in order to properly (read: safely, without marring the aluminum) remove the top caps from the fork. While openly contemplating what to do about this on Facebook a friend of mine, Mark Dombrowski (also the MCMBA Trail Coordinator for ILRA) offered to make me an aluminum socket to meet my exact needs. He’d done the same for himself in the past, and this one was like his, but with the incremental improvement of a 15mm hex cap for turning the socket.

This sort of socket (or one with the face ground flat) is needed because FOX top caps have very thin flats and are made of aluminum. The internal flaring on most sockets either won’t mate well (best case) or will round off the cap (worst case). Grinding a hardened socket flat can be quite a pain, and having a softer tool for turning the aluminum is a good idea, so he came up with this.

I’m really thankful to have one of these. Once the replacement parts come in I’ll be able to rebuild the Titus’ fork, and I also should be able to use this on the fork which’ll come on the bike that I’ve currently got on order. This is a really nice part.

Here’s a few more views of it:

· Looking into the business end of the socket which mates with the 26mm top cap.
· The opposite end of the socket has a 15mm hex fitting.
· Oblique view showing the nicely machined part.
· Socket with Industrial Sharpie labeling so I can remember its exact sizes.

Fat Tire and Potawatomi

This past Sunday was the Triple Trail Challenge, a rather nifty fundraising group ride out at Pinckney State Recreation Area which spans parts of the normal mountain bike trails and also some trails which are only open to bikes for that day. I headed out with Jeremy and Sol and had a really great time. The route was rather nice and I’d love to do this ride again. The Lakelands Trail was a bit rough, and some of the dirt roads were a bit slimy due to recent grading and spraying, but it all added up to an outstanding 38.5 mile ride.

While the ride itself is free, it’s used as a fundraiser by the Potawatomi Mountain Bike Association by selling t-shirts, beer glasses, and trying to sign up members. This seemed to be really successful, as I heard there were 600+ people out for the ride, they acquired over 100 new members that day, sold out of t-shirts, and were running short on pint glasses. After the ride there were ample supplies of complimentary chili (vegetarian, I believe) and Arbor Brewing Company beer for all those who participated.

I was one of those who bought one of the glasses (t-shirts were sold out when I tried to get one), and it can be seen above filled with some of New Belgium’s Fat Tire Ale. I’m not a huge fan of this beer, but it is a pretty solid, reliable beverage. Since it’s now available in Michigan I’ll probably pick up a few more bottles of their stuff, and it’s nice to know that these glasses nicely hold an entire 22oz bottle.

I-69: Reached

A bit over two years ago I attempted to ride from near Addison Oaks up to I-69, but fell short due to the trail being washed out. Today, the first would-be-work-day of my current vacation, I decided to try again, this time starting from my house. Even though I had to cut it a bit short due to Roxie becoming ill and didn’t make my desired 100 miles, I think the ride was a success.

The ride started out with me meeting a friend named R (he asked me not to mention his name because he was taking a much-needed break from work), and he and I made our way up to the Polly Ann Trail. At this point he turned west and began heading home, while I went northeast and continued on towards my destination. After crossing the Lapeer county line and weathering the rough, unkept (although occasionally mowed) trail I hit my goal, the Interstate 69 underpass just south of Lapeer. I carried on for a couple miles further north before turning back and beginning the ride home.

On the way out I’d had to cross a rather questionable bridge which washed out almost four years ago. Back in 2009 Erik, Kristi, and I happened across this bridge and turned back, but now some enterprising soul(s) had built a timber crossing so I was able to easily keep going. Despite a 10′ drop on to concrete and iron I used my bike as a balance beam and walked across the 10″ wide wood plank to get to the body of the bridge before crossing another two on the far side.

On the way back I’d intended to bypass this bridge via dirt roads, but a bit of a miscalculation resulted in my traversing it in the other direction. While stopping to take pictures I was surprised by Dustin rolling up, having chosen to take the same sort of ride as me today. After heading south via dirt roads and into Stony Creek to refill water and drink mix, and then decided to detour through The Pines before heading home, but while in there I came across someone who let me by then seemed to be looking for his friend Charles. I headed up ahead to let this person know that his friend is all right (but just a ways back), and realized it was Charles, brother of Mr. George Hotelling, who I’d met at a housewarming party this past winter. What an unexpected coincidence.

Then, on top of that, it turns out that a former coworker spotted R and I riding up Lake George, but didn’t catch up with us before we’d turned off the road.

Everything was going great until Danielle texted me while I was talking with Charles and his friend to let me know that Roxie wasn’t doing so well. She had been pooping paste for a couple days, and this afternoon Danielle contacted me to let me know that Roxie had begun vomiting and then wouldn’t get up off the lawn and come back inside. Worried she took Roxie to the vet, and I rushed home. I had another 20 miles in me and could have broken 100 today, but Roxie is more important than that. (It turns out that Roxie has a GI infection resulting in her having digestive issues and being lethargic. She’s on a diet of mild food and antibiotics for a few days, after which she’ll hopefully be better.)

All done, here are today’s stats and route map on Strava. This was a good ride, and I’m thinking that I’d like to do something similar before vacation is over; perhaps some time early next week.

Here are the four decent photos that I took today:

· Looking north along a washed out bridge on the Polly Ann Trail just south of I-69.
· Looking south along a washed out bridge on the Polly Ann Trail just south of I-69.
· The Titus on the Polly Ann Trail where it passes under I-69.
· Looking down at the board which I walked to access the washed out bridge along the Polly Ann Trail.
