Sliding Dropout Issues

Published July 25, 2010

After washing off the remainder of the mud from yesterday’s race I set about trying to fix the problem with the rear wheel rubbing on a chain stay. This appeared to be due to one of the sliding dropouts sliding, but after looking into it more I think what’s actually happening is that the dropout is rotating slightly while braking due the the bolts being slightly smaller than the slots they go through. So, as can be seen above (when contrasted to this picture) I added some ground down wingnuts to the dropout adjustment screws and changed the outer plates to a set of flat and split lock washers.

The original outer plates appear to have raised ridges in them to alleviate this shifting, but the ones I have are so squished and worn that I don’t think they fit quite right and thus were having the same issue. I’ve tried emailing VooDoo Cycles on Wednesday to buy replacement sliding dropouts, but they haven’t replied, so I think I’ll have to take other steps.

Knowing what forces are in play on the dropouts will hopefully allow me to set things in proper place so they don’t shift any while riding. An initial test around the neighborhoods seemed to help, but not being on trails there was very little braking to be done. If this doesn’t work I’ll also try Fiber Grip to increase friction in the frame vs. dropout area, making larger outer washers/plates, and adding bushings around the screws. I’m also considering adding a link to the chain to both get a quick link in place and allow the wheel to be moved backwards putting the edge of the tire at a wider part of the stay to alleviate/offset the tire rubbing giving it more room to flex/move to the side if it does slip.

Here’s a couple photos of the bike with the new suspension fork, brakes, and Lagunitas Brewing Company cap (on a Niner YAWYD) on it: 1 · 2 · 3 · 4.

Save for the slipping dropout issue I rather like this setup. The fork isn’t the greatest, but it’s a good squishy fork that fits the bike well and is comfortable to ride on.

2010 Tree Farm Relay: Mud!

Published July 24, 2010

Today was the 2010 Tree Farm Relay, a quite-nice relay race in Novi’s Lakeshore Park. I was on a team with Martin, Nick, and Bill, with my lap being the third out of us four (Martin: 1, Nick: 2, Me: 3, Bill: 4). Our team, Heck’s Angles, came in 17^th out of 36 (Sport Men results), a middle of the pack standing.

It had been raining all morning and throughout the start of the race, but with the rain letting up just before my lap the light rainy mud began drying, smearing the entire course with peanut butter-like goo. Prior laps had a much thinner, rain-addled mud left on bikes, and the later laps had denser mud that mostly just packed into people’s tires and made things slick. Mine packed into the entire drivetrain, clogging the chain and filling the bottom bracket, adding a good five pounds to the bike. This slowed everything down, yet despite it the race was still fun.

While riding I didn’t have any real mechanical problems, but my rear wheel was starting to slip a bit in the dropouts, causing my rear tire to just barely begin rubbing a chain stay at the end of the lap. More thankfully last night’s replacement of the fork and brakes didn’t cause any problems and the new brakes performed as hoped (and became bedded in nicely) and the air fork did it’s job. I think the fork may need a bit more air for me, but it was otherwise quite a bit nicer than the super-steep rigid fork.

After the race and at Marty’s suggestion I took a quick dip in Walled Lake to clean myself off, then settled in for a few pints of the Dark Horse, Original Gravity, and Liberty Street (local, tasty, Michigan) beer available on site.

I’m looking forward to seeing some other people’s photos of the race, particularly as someone got one of me going into the crater, blue liquor shot in hand (they are obligatory and handed out mid-course, you know) and I’d like to see how it came out. In the mean time, here’s some select photos that I took today:

· Me standing with my bike right after finishing my lap at the 2010 Tree Farm Relay as part of team “Heck’s Angles”.
· Other Dave and Hodaddy (Joe Foy) immediately after Joe finished his lap.
· Nick’s bike received only a light spray of mud on the second lap.
· My bike caked with mud from the third lap, as the trail was drying out.
· Seat stay bridge and seatpost caked with pudding-like mud.
· Detail of the mud and grass caked bottom bracket before washing it off.
· Detail of my bottom bracket after removing the large chunks of mud.
· Nick hosing off his bike to remove the mud from it.
· While riding the rear dropouts slipped slightly and at the end I was getting some tire rub.
· In Walled Lake some people demonstrate the wrong way to wash a bike. I feel bad for the hubs and bottom bracket.
· Looking through the finish line, including the bamboo gate made by Loren.

A good time was had by all, except for maybe the rider who broke a derailleur (or something similar) and schluffed back to the finish line. He handed off his lei (the batons for this race) to his team mate, then angrily shoved/threw his bike only to have the front wheel dig in and make the bike circle around to hit his team mate right as he was setting out.

One Thing You Should Never Do

Published July 24, 2010

I just did one of the things you should never do: change major bicycle components the night before a race. In this case I’ve fitted a new fork (Manitou Drake Super Air 29er) and brakes (Avid Elixir R). Tomorrow morning is the 2010 Tree Farm Relay, so hopefully everything will work out well.

Brakes aren’t completely bedded in yet, but some riding around the neighborhood and parking lot helped that along. The new, taller fork has helped the feel of the bike tremendously, and I suspect the squishyness will make the ride a bit nicer too. I did find a couple small drops of what I believe to be brake fluid on the caliper near the banjo bolt and I’m not certain where they came from, but they have me slightly worried. Hopefully that concern is for naught and none ended up on the pads or rotors.

Now, time for a shower and bed.

Test Ride, Sore Muscles

Published July 21, 2010

Today after work I took a test ride around Stony Creek with the VooDoo Dambala to see how I like riding a rigid single speed on very familiar single track. In short, after letting a bit of air out of the front tire it was all quite great, except for the eventual soreness in my triceps and trapezius. I feel a bit sore, worn out, and beat up, which makes sense seeing as I just rode a rigid bike fairly quickly over ~10 miles (2x Pines, 1x Back Nine, 1x Snake/Coaster, 1x Pines) of sometimes not smooth single track.

While out riding I ran into Marty and some of the REI / MMBA group of new riders she was showing around the trails. I hung around with them for a bit to sweep / watch the folks near the back to be sure everyone was okay, then I took off to ride some more. I offered to show folks around the Roller Coaster, but no one took me up on the offer. As this was group of new riders it was fairly understandable.

The new 19T cog that I acquired and fitted last night did exactly what was intended: allowing me to actually climb hills while still being able to carry a decent speed through familiar parts of trails. Unfortunately, right near the end of the ride I found that one of the movable dropouts had slipped, and on hard corners the tire could be heard rubbing on a chain stay. When changing the cassette yesterday I noticed that a portion of the dropouts was a bit deformed, so I emailed VooDoo Cycles to ask after suggestions or replacements. Tomorrow I’ll straighten things out and tighten stuff down more, but maybe there’s something better to be done that VooDoo can advise on.

Now, time for bed and thought on if I’ll ride this bike or the Titus during Saturday’s Team Tree Farm Relay.

New Bike, Falling, Missing Flags

Published July 18, 2010

Today while trying out the new (to me) single speed at River Bends I washed out the front wheel and fell. Oops. (Crash area photo above or here. Yes, it’s blurry. It’s kinda dark in those woods.)

I also confirmed that the 34:16 gearing is too much for me and I’m now pursuing acquisition of a 19T cog. This should give me a much easier (within 1% of the ‘standard’ 32:18) gearing, which should be good for getting going again with 29er single speed trail riding. Since I couldn’t make it up a couple of the hills (the sharp turn then up ones) I think this will do. Now I just have to find the cog and tool, which I’d prefer to do before Tuesday so I can take the bike out to the Tree Farm for the group ride.

When out at River Bends I had a rather unplesant surprise. I’ve been working the MMBA and Shelby Township to build new mountain bike (and hiking and running, of course, since they are shared) trails in the park. On Friday I marked another large segment of trail for us to build out, but someone removed almost all of my tape flags over the weekend. I suspect it’s someone trying to keep new work (or bikes or something?) out of “their” part of the park, but it’s hard to say. I also found dirt bike tire tracks (photo) on both the two track and single track, and a couple torn up areas from the dirt bikes riding off the trail and doing doughnuts on the two track. I guess these are just the sort of things that have to be dealt with as part of the process (and inherent problems) involved in building and maintaining trails.

Also while out at River Bends I ran into a couple who were out looking to ride the trail for the first time. I started to take them through it, but after a little bit we ended up parting ways as they opted to ride some two track together and I sent off for another lap of the single track. I’m really glad to see people heading out to the trails to check them out.

VooDoo Dambala

Published July 17, 2010

Ever since the Island Lake Bike Demo I’ve found myself wanting a rigid single speed bike for occasional trail rides. After failing to purchase a Redline Monocog Flight 29er I started looking at used bikes on the MMBA Forum and came across a well-equipped VooDoo Dambala in my size for US$600. After driving out to Chelsea to meet the seller and look it over (and eat at Zingerman’s Road House on the way back) I decided to purchase the bike. It’s just what I want, a steel framed bike that fits me with good quality parts at a fair price.

At 34:16 (2.125:1) the gearing is a bit tall for me, but being a standard single speed hub I shouldn’t have a problem fitting a new (and more appropriate) cog. I’ll give it a go as-is first, since my legs are much stronger since my my last single speed experiment, I don’t want to pick a new gearing before really trying it out.

The bike came with the levers set up British-style (front brake on the right) which is common on mountain bikes ridden by motocross folks, but not right for me. Since taking the photos above I switched them around and swapped the Time pedals for Eggbeaters so it’s now ready for a test ride. I still have to get a new saddle and adjust the rear brakes a tad (clean, or perhaps bleed them), and maybe fit some Ergon grips, but it’s otherwise all ready to ride. Hopefully I’ll be able to get out tomorrow to try it out.

The bike came equipped as follows:

Frame: VooDoo Dambala 18″
Stem: Bontrager 90mm
Fork: Bontrager Switch Blade Race X Lite Carbon Fiber
Wheels: Sun Ringle
Seatpost: Thomson
Bar: FSA CarbonPro
Crankset: Bontrager
Tires: Specialized S-Works The Captain
Brakes: Hayes Stroker Trail (Avid Clean Sweep G2 Rotor in Rear)
Saddle: Selle Italia Flight
Cog: Surly 16T
Chainring: 34T
Bash Guard: Salsa
Grips: ODI Ruffian
Pedals: Time

Cock ‘n Bull Ginger Beer

Published July 11, 2010

Here’s a bottle of Cock ‘n Bull Ginger Beer, purchased at the gas station at the corner of Grange Hall and Mackey Roads after Erik, Kristi, and I rode the East Loop (Gruber’s Grinder) at the Holly-Holdridge Mountain Bike Trails, which are more commonly known just as Holdridge. This was a quite challenging (but fun) trail, which took us 2:20 to complete the 15.5 mile route riding at a quite relaxed pace. It has everything from flowing sections of hard pack through the woods to 6′ high piles of field stones and reasonably high log piles. (Photo of Erik going over the biggest of the log piles.)

After the ride (and purchase of snacks) we headed over to Wildwood Lake in Holly Recreation Area and swam for a while to cool off (photo). Unfortunately while out swimming (and taking underwater photos) my supposedly waterproof to 10′ Olympus Stylus 850 SW sprung a leak. The camera started complaining that the memory card’s contacts needing cleaning, and after I opened the memory card / battery card compartment I found it to have water in it. It’s now sitting in a container of desiccant, so hopefully it’ll start working again soon and I can just put it to use as my standard travel point and shoot / bike jersey pocket camera.

Despite our snack of good soda and potato chips, having just biked for 2:20 and swam for 45 minutes we were getting a bit hungry, so the next stop was Union Woodshop in Clarkston, MI. This offshoot of Clarkston Union, one of my favorite America food restaurants, has a menu of great looking BBQ dishes and is some place I’d been wanting to try for a while.

With $0.87 glasses (mason jars, really) of Badass Beer (yes, the Kid Rock stuff, a passable lager) on special during the final game of the World Cup (which Spain won) we each ordered pulled pork with a variety of side items. I chose mac and cheese (ala Clarkston Union) and sweet potatoes (with roasted jalapeno and a hint of maple), which can be seen here along with some corn bread and sweet butter. Typcial of most midwestern restaurants portions were large enough to ensure leftovers. I’ll definitely want to go back there, but the typical 1.5 hour wait on most weeknights may make this difficult. I guess we’ll just have to plan for mid-afternoon on a Sunday again.

Shelby / Macomb Township Warzone

Published July 4, 2010

One of the few things (besides “free” music and movies) that will elicit civil disobedience in white, middle class families is the chance to use 1.4G (formerly Class C) explosives on the Fourth of July. I really enjoy seeing all the explosions around the area, so around dusk I set off on my bike to wander the local neighborhoods and watch people set off various glittering fires.

This ride ended up being roughly 12.3 miles, which was a nice cap on the day. Earlier Josh (my brother in law) and I had ridden Bald Mountain and Addison Oaks, but after a nice pile of picnic-type foods at my parents house and an unexpected nap I felt like getting back out and riding some more. A desire to watch people play with pyrotechnics provided the perfect reason to do so.

The REI Garage Sale Is Great

Published July 3, 2010

Today after getting Danielle fit on her bike by Ernie up at Cycletherepy (which went very well and is highly recommended) we swung by REI to pick up some stuff and check out the remains of the Garage Sale^†. While there I picked up a returned Cateye Velo 5 computer labeled “Computer is not working” for $1.93, marked down from the original $20. Looking it over, the only thing wrong with it was that the original buyer had pushed the rubber MODE switch on the back in so far that it was jammed, causing the computer to not function. A few quick pokes with a pin to move the rubber switch back to the hole and everything was back to normal.

I also grabbed a jacket for $29-ish which had been returned because part of the collar was beginning to pill. Marked down from $100, nice looking, and something that I’d considered purchasing at full price last winter I couldn’t pass it up. It should make a very nice early winter / springtime jacket, and maybe something nice for XC skiing.

^† In case you haven’t been to one, garage sales at REI are periodic clearance sales where non-new returned items are sold at huge discounts as non-returnable. Everything is tagged with the reason for return and the age of the item, and prices are typically an order of magnitude below the original price.

Fall Down Go Scrape

Published July 2, 2010

Today while out riding my bike at Addison Oaks I fell and scraped up my arm. I think I also banged my shin and hip a little bit, all while packing dirt into various parts of the handle bar. That’s part of the excitement of riding a bike in the woods, eh? Good thing the weather was perfect and there were far fewer bugs out than there have been in past days. The rest of the ride, which started at the Clarkston Road crossing of the Paint Creek Trail and went through Bald Mountain, was nice, fun, and generally uneventful.

Here is a photo of the place where I fell. For those of you that know the trail, it was on one of the curves right before the small bridge/boardwalk which has the sharp uphill, banked, right-hand turn after it. Yes, it’s a very basic spot. I just wasn’t paying enough attention and either washed out the tire or got too close to the edge of the trail and slipped into the soft/shrubby stuff.

Thinking back, it’s now been a bit (two weeks?) over a year since the last time I fell at Addison Oaks. The last time was when I washed out the front wheel and left a plug of skin on a screw hole of my other bike’s stem.
