Nobody from the gang was available to ride at lunch today, so I became unmotivated and stayed in my cube. I would forgo the pleasantries of two-wheeled recreation, and work on my status report instead. Later in the day, however, I got an instant message from Kristy saying she wanted to ride. It was a bit late in the work day, but not too late. We met in front of my building, and headed for the trails on our single speeds.
Kristy’s 29er single speed has gone through a transformation of sorts this past week. Last weekend Marcus helped me convert the tires to tubeless, and Jeff P helped me dial in the new mechanical disc brakes later in the week. Jeff P also cut down the bars to 26 inches wide. The On One Fleegle bars come 28 inches wide so the rider can custom size them. Additionally, we stuck some new Specialized Body Geometry grips on the bars, replacing the very thin stockers. Kristy let me take a little spin on the bike today when we took a break for a photo shoot. Wow! It is safe to say that I now covet her bike.
The Avid mechanical disc brakes were a major upgrade for this bike. Not that V brakes are bad, but we could never get the rear brake pads lined up properly on the rims…a problematic combination of chain length, horizontal dropouts, and brake post mounting bracket positioning. The rear disc caliper required a number of spacers for proper alignment, but is completely dialed in now. Stopping is now effortless.
The tire selection for the tubeless project consisted of the stock wire bead WTB Nano Raptor 29×2.1 for the rear, and a new folding bead WTB Weirwolf 29×2.55 LT for the front. Both tires sealed up nicely on the first attempt with the Stans No-Tube kit. The process appeared pretty easy. It’s possible though that Marcus just has the routine down and made it look easy. Still, it looked like something I wouldn’t mind tackling myself. We aired up the rear tire to 28 psi, and the front to 22 psi. I thought the bike was pretty smooth before, but now with the combination of the big wheels and plush tubeless tires, it’s like butter. My 26 inch wheeled bike felt a bit jarring when I got back on it, even with my giant tire on the front. I’m looking forward to a complete test ride on Kristy’s 29er sometime soon, but the preliminary results are promising. The Holy Grail? We’ll see…
Kristy is very pleased how the bike came out, and I expect she’ll now spend less time on her Stump Jumper!
