It’s been a while since the last update – much to tell. I’m going to break it into two posts: the last bit of Texas first and then New Mexico, so far.
I had a great experience in unfortunate circumstances at Crazy Cat Cyclery in El Paso. I’d ordered replacement tires to be drop shipped to them and anticipated a quick and easy swap. I’d swung by the bike shop Monday the 1st to introduce myself and got a call Tuesday morning that the tires had arrived. I was already on my way in to town, so it only took 15 minutes or so to roll into the parking lot. I chatted with Dave, who I’d met Monday, just to confirm the plan of action. He pointed me at a couple good spots to check out: a falafel spot around the corner and San Jacinto Plaza a few blocks away downtown. Lotte and I set off for the alligator fountain in the center of the plaza and hung out for a bit… then we got a call from Dave. Seems that the tires I’d ordered were not tubeless compatible.
Tangent for non bike weenies – the traditional setup, tires with tubes inside, is being supplanted in a lot of applications by a setup using special rim tape (to seal spoke holes), rims and tires that are tubeless compatible, and a healthy potion of latex sealant sloshing around inside the tire. The main feature that makes the rim and tire tubeless ready is a very tight fit at the bead – the place where the tire latches on to the rim. WTB has a good picture of what I’m talking about here.
I was a retrogrouch regarding tubeless. Mike at Maine Bike Works suggested it when we set up the bike, but no no no I was going to run with tubes. Then I talked with Liza and Tyson about their experiences on the Baja Divide Route. The word from them was that a ride like that (still on my to-do list) would be ridiculously difficult with tubes, much much better to go tubeless. So I converted. It was a good decision – it’s impossible to know how many patches I would have put on tubes by now, but I can tell you that I accidentally ran over a couple twigs with 1″ thorns attached, gritted my teeth and pulled them off the tires. Bubbling latex, hole sealed and off I went. So I am very much a convert; Mike was right!
Back to a week ago in El Paso: I’ve had Schwalbe G-Ones on Molly Fin since the beginning. They’re got a tread that works well on pavement or dirt and plenty of volume which makes for a comfortable ride. But I’ve been doing most of my riding on pavement and I noticed that the tires were wearing quickly – especially the rear. So I decided to switch to Moto-Xs and in a fit of misplaced optimism managed to assume that any 27.5+ tire would be tubeless ready. Sadly, no. We had a couple options: Moto-Xs with tubes or stay with the G-Ones and swap front to back. I decided on the swap and Dave agreed with me. We looked for other 27.5+ alternatives that I could get shipped to the next big bike town, Tucson – no luck at all. I’m going to write Schwable an email, suggesting the Moto-Xs go tubeless, but that won’t help me this ride. I’m guesstimating that by the time I reach Tucson and fresh G-Ones, I’ll have a little over 3k miles on this set (2853 miles now) and I guess 2.5 – 3k is what I can expect going forward. It could be worse: one of the tires Dave and I looked at (and rejected as being too dirt oriented) was the Terravail Cumberland. I looked at a review of the tire later, just out of curiosity.
To illustrate tread wear, each tire was photographed (front at left and rear right) after about 300 miles on a somewhat equal amount of singletrack, gravel and pavement… 260+ miles loaded and over 40 unloaded. As shown, the grooved lines on the center tread are still intact. I would expect the tread on the Durable Cumberland 29×2.6 tires to last well over 1,000 miles. *
