Logpile!

Here, have a photo of the newest addition to the trails at River Bends: a log pile. This has been in place for a few days, but this afternoon I finished it off by adding another log to the front to make it more approachable. I also added more glue dirt to help keep it all together. Another view of the logpile (from the direction which it is typically ridden) can be seen here. At River Bends when the parks people cut downed trees from the two track, they tend to leave nicely maneuverable ~4′ pieces sitting in the woods along the trail. Finding a few fresh, non-rotted ones of these is trivial and they can easily be used to build solid log piles. For anything else I can find other fallen, dead trees and cut them to length with a handsaw.

This afternoon’s trailwork also included tweaking a corner to increase its radius (photo) and adjusting another to flow more smoothly to cut down on people overshooting the corner and washing out. Damage to both the trail surface and edge made it obvious that this was a common problem on these corners. Here is a helmet cam video of me washing out on the pictured corner and falling. Whoops.

World’s Largest 555 Timer?

This traffic control device (which is essentially a timer) may just be the world’s largest 555 timer.

This was seen at the corner of 22 Mile and Shelby Roads while on a bike ride this evening. I headed from home, up to River Bends, out the back part of it, over through Clinton River Park Trails (which were rather muddy), and then wound through neighborhoods back towards home. Total of 22.3 miles in 1:44:27.

Doughnuts at Paint Creek Cider Mill

…just a quick photo from yesterday’s impromptu bike ride from when we stopped at Paint Creek Cider Mill and split a bag of cinnamon sugar doughnuts about 30 miles into riding. As Nick said, due to five people being present and a dozen doughnuts in the bag, a few of us had to “take one for the team” and eat three… Mmm…

Yesterday’s weather could have been a little nicer as sprinkling rain was a little was a little unpleasant at times, but otherwise it was a nice cool autumn day. I’m really looking forward to a couple months of this type of ideal riding weather.

River Bends Trailhead Kiosk: Complete

This morning, along with help from Jeremy Verbeke and Scott Retford (and Bob Costello last night in collecting the Lexan) the kiosk at the River Bends Trailhead was completed. This involved hanging the signs, covering it all with Lexan, and fitting some wooden strips that I cut and drilled last night (picture). Here is a photo of Scott and Jeremy standing next to the kiosk right after we completed the sign hanging.

This kiosk (along with much of the trail signage) was donated and build by Spencer Wood and Troop #242 as part of Spencer’s Eagle Scout project. It’s a nice improvement on the standard MMBA Kiosk Construction Plans, is extremely well built, and should last for years. This is one of the best constructed trailhead kiosks that I’ve seen.

The signage includes a trailhead-specific version of the map, a QR code allowing easy download of a PDF of the map to one’s smart phone, and some basic trail rules. The kiosk also features a sign from Aktion Club, a Kiwanis program for people with disabilities who helps with maintenance of the first mile of two track trail.

This completes the current River Bends trail system allowing us to move on to the next phase. I just recently received approval to expand the single track even further, so once the mosquitos start dying off and leaves start falling from trees construction on this next segment can begin.

Garmin Edge 500 Distance Aliasing Issues Alleviated By GSC 10 Sensor

Past experience with wildly varying data has prevented me from trusting GPS-based devices for accurately logging distances while riding mountain bike trails, but after hearing reassuring reports of modern units and seeing how useful it could be to have one unit logging data for all three of my bikes and automatically aggregating it I decided to give it a go. I purchased a Garmin Edge 500 cycling computer and a GSC 10 wheel speed / pedaling cadence sensor a month ago and after beginning to use it things seemed quite accurate, but I continued to be a bit suspicious that it may not be providing as accurate of data as it could. So, I decided to do some tests.

The results of these tests have shown that when the Edge 500 is used in conjunction with the GSC 10 it is just as accurate as a wheel-based computer and can be relied on to provide sufficiently accurate distance measurements while riding curvy mountain bike trails. Coupled with all the extra data that the system can log (heart rate, location, temperature, cadence, etc) it’s quite a nice system for recording data.

Without the GSC 10 (using only GPS-based data recording) the Edge 500 showed drastic undermeasurement, 20.70% on a typical Southeast Michigan trail ride and 33.87% in a worst-case test scenario.

Broken Spoke II

Today I broke another spoke; the same one that was quickly fitted as a replacement before the Hanson Hills XC race by a guy from Grayling’s The Bicycle Shop. I guess 2.5 months of riding on a quick (and much appreciated) fix isn’t too bad. The wheel is wobbling a bit so I won’t be riding this bike until I can get it fixed up.

I was surprised by how it broke. Much like the last time I was riding along pretty trivial single track, a short and relatively smooth uphill section at Stony Creek and not going over anything more difficult than a front lawn. Suddenly I heard a BANG sound, stopped to look at the wheel, and saw one end of a spoke hanging into the center near the hub.

Oh well, that’s life I guess. I can’t complain too much, as I’ve got at least 2466 miles (likely more, as not all were logged) on these wheels. I’ve got some 291mm spokes here from building up a wheel set back in April. DT Swiss’ Spoke Calculator is recommending a 293mm spoke, but hopefully I’ll be able to make do with something 2mm shorter.

UPDATE: The replacement spoke did the trick. Wheel’s held up for ~30 miles thus far.

Lunch Time Bleeding Shoulder

One advantage to occasionally working from home is being able to get out for a bike ride at lunch time. Yesterday after a string of meetings I took a quick drive up to River Bends and rode a couple laps during lunch. This worked out wonderfully and was a nice way to break up the day.

At one point while riding I clipped a tree with my shoulder. While it didn’t really hurt (no more than when one normally brushes a tree with a shoulder), a few miles later I noticed blood soaking through my shirt. I imagine this has something to do with how damp my shirt was with sweat, and the wicking material did it’s job and spread moisture nicely. Funny, that.

Another Day, Another Downed Tree…

After one of the recent windy days another dead tree fell on the trails at River Bends, and thankfully I was able to remove this one with just a hand saw and a bit of creative thinking. The tree was partially rotted, so there was only a solid core to saw through. Fifteen minutes of actual work and it was gone.

Once the tree was cleared I spent some time wandering around some undeveloped parts of the park, and from what I can tell there’s a really great opportunity to build some more single track heading generally north from the end of the current loop. this needs a little more thought, but I think we may be able to build a return trail so that most of the route north back to the trail head can occur on single track.

Here is a (blurry) photo of the downed tree and some tools right after I arrived to remove it.

There were a surprising number of people out riding the trails today, and this was rather nice. It’s really great to see a bunch of people out enjoying them.

Injured Robin at Bald Mountain

Yesterday evening while riding to Addison Oaks by way of Bald Mountain I came across this robin laying on it’s back in the middle of the Conklin Road connector. It was laying across the entire trail, and it took a bit of effort to stop before running it over. Looking like it’d just been in some sort of fight it just laid still while I took it’s photo, doing little beyond pivoting it’s head to look at what I was doing.

After a minute or two of looking at it I tried to get it to grab on to my finger with it’s feet, but seeming uninterested in this I tried to pick it up and move it off the trail. As I went to pick it up it bit/pinched me with its beak then lopsidedly flew away down the trail. I’m quite curious what it’d been hurt by. Perhaps a cat or maybe some larger bird?

Once the bird was moved from the trail I carried on, not stopping until I got back to the car, a bit more than 2 hours later. It was a great night for a ride on one of my favorite local trails.
