Some thoughts on tubeless bike tire tech, and random food for thought.

Tubeless. I know, most people don’t think there’s a debate, but there is. I converted the SX-C2 wheels on my Giant to tubeless using only Stans yellow rim tape. It works fine with the RaRa’s that came on the bike, but the Tioga Psycho Genius and the Conti Mountain King I was running on it won’t seat on those wheels, not even with an air compressor. Having decided after an exhausting and treacherous ride this morning that the WTB Nano I’d been running on the back of the SS was finally toast, I endeavored to mount said Tioga on the Pacenti wheel on the back of the single speed. It was completely drama free. So what’s this with a debate?

I’ve heard people who ride quite a bit, and have a lot to do with bikes say that tubeless is not worth the trouble, it doesn’t work, etc. – and not to try it. I can’t help but think this is complete hog wash. No, those tires didn’t mount to the SX-C2 wheels, but then, Giant doesn’t rate those as tubeless compatible wheels, either. It’s also fairly well known that there are some tire and rim combinations that simply don’t work, even though both may be “Tubeless Compatible” in their own way. The bottom line is, do a little home work, and be prepared to improvise, should the need arise. I don’t run stupid low pressures in my tires, I weigh about 220 with a loaded Camel Back on, and run 30psi in the rear, and 25 in the front. I’ve not had an issue with burping, I haven’t had a flat since I started running tubeless, and the difference that the 2-4 psi less in the tires makes both in ride quality AND traction is noticeable, welcome, and huge.

So, if you’re on the fence, give it a whirl. Tech has come a long way in the past couple of years towards making tubeless better and easier.

Also, your random musical thought for the day: Joe Strummer would have been 61 years old today.

In which you get an update, but no pictures. Yet.

There’s a big reason I’ve been busy and not posting a lot lately. It’s not a good reason…or it is a good reason, but it’s no excuse. Something like that. I mentioned when I owed you an update that I got a new job. I also mentioned that I’d finalized a few things on that new mountain bike trail. That’s really dodging the issue a bit. The truth is, I got a job with the city parks and recreation department that new trail is in. My job is…building trails. So, I have paid time to spend building trails with an mini excavator owned by the city, that I don’t have to pay for, or buy fuel for. Really, all I have to do is show up and build trail. And train volunteers who want to help. So most Saturdays, we have volunteer crews out there. This is in addition to the work days we still run on our existing local trails on the first and third Sundays. That’s sort of a wreck too.

Recently, an property owner adjoining the park where our existing trails are had their property logged. We discovered that some of the trail originally built in the park….isn’t. So the section of trail that the loggers did their thing over top of is destroyed, and we’re building a re-routed section that stays inside the park. If I’m honest, the most impressive thing so far about this situation has been the lack of finger pointing by the groups in the park about who was at fault for the trail being on private property. So far, everyone is just sucking it up and helping build the re-route. Which is nice.

And don’t think that my being too busy to post has in any way hampered my riding. It hasn’t. I’ve had some great rides lately, both because they really were great rides, or because they maybe were marred by some mechanical difficulties, but the company and just the fact that we were out riding made them great. And really, isn’t that the important thing? On one ride a couple of weeks ago, my Single Speed started making an alarming creaking sound rather suddenly. It was so bad I was afraid I’d broken the frame. I got home, put the bike in the stand, and took the bottom bracket appart, cleaned everything up, threads, bearings, frame, all of it. I check the frame very closely for cracks, but didn’t find any. I put the bottom bracket back in, and torqued everything down right, and gave it a try. Behold, it worked beautifully, and was silent. While I would like to upgrade the Single Speed to a nice Ti frame (Lynskey?) I must say I was relieved to not HAVE to do so.

The last two times I’ve ridden the Anthem, I’ve been plagued by pinch flats. This is more confounding than normal because I checked the tire pressures, I’m running exactly what I’ve always run, I weigh the same, and yet two rides in a row, I’ve found snake bite holes in my tube after a rather jarring impact on the back wheel. Which either means I’m riding worse than I was, or I’m going faster than I was and it’s thrown my timing off, or just causing me to hit harder and pinching. Either way, it’s frustrating. As such, I’ve decided to consider this new fangled tubeless technology. Although, you could argue, I’ve gone about it backwards.

I converted the rear wheel of the Single Speed to tubeless. Yes, just the rear wheel of the Single Speed. Here’s why, lest you think my crazy(er). The tires on the SS (WTB Exiwolf front and Nano rear) have both been¬†victims of sharp rocks – cut right through. But running with tubes, that’s not a huge problem, because the cuts are in the tread. It also happens, that the Pacenti rims on the SS are designed to be tubeless compatible. I have a set of Racing Ralphs that I took off my Anthem – I can’t say I was horrible impressed with them, especially on the front. I was going to grab one of those and throw it on the back of the SS, since I decided I would “use both of them up” on the back of the SS since I don’t think they’ll cause me traction issues there. The surprise came when I let the air out of the Nano and went to break the bead to remove the tire. It was HARD to get it to release. So, just for giggles, I took the tube out, put the tubeless valve stem (the only one my LBS had…another reason I only did the rear) in the rim, and put the tire back on. A quick shot with the air compressor and the beads seated just like they should, and it blew a bunch of air out of the hole in the tread, like I knew it would. But it looked good around the bead. So I took the tire off, put a good old fashion patch on the inside of the hole in the tread, put the tire back on, seated the bead (cheating alert) then let the air out, took the valve core out, and dumped in my Stans juice. Put all that back together and inflated it, and sealed everything up and….presto. Tubeless. Like it had a brain. So how is it?

It’s great. I dropped the pressure from 32 psi to 30 psi. I took it for it’s single track shake down this morning. The grip was outrageous. 2 psi made a lot of difference. The feel was also much better, the ride as a whole was less harsh. I rode the bike pretty hard, hit some off camber roots, jumped it, carved some hard turns, and basically tried to make it burp, but it held like a champ. So now I need to do the front. And I need to figure out how to deal with the S-XC2 rims on my Anthem – a full Stans rim strip kit, or just some stans tape? Ah well, I’ll figure it out.

I’ll hit y’all again soon with pictures. I’ve got trail pictures, flower pictures, pictures I probably don’t remember taking, and probably pictures of me playing with fire.

I’m not dead. Yet.

I know it’s been a while since I posted. Sorry. I’ve been a busy man. I’ve spent three days out of the last two…or has it been three?..weeks in meetings with a local city government about a new trail system at a park. I dedicated bike trail system. I’ve also been on the property a couple of times, and made some very interesting discoveries. Including that I’m going to be building a LOT of elevated trail over a creek on the property. Each crossing – and I’m aiming for two – will need 40 to 60 yards of deck elevated to an unknown height as of yet, but I’m guessing at least 2 feet. I’ll know for sure when the water goes back down. I’m very excited about this project though, because I really do feel like mountain bikers finally are getting cut loose in this area to build a real playground.

Speaking of playing, I have gotten some playing in. Our Saturday Social last week was fun, we had a good turnout and picked up a few new folks. One of the new folks we picked up was a seasoned rider who had never been in the park before. Four of us ended up doing over 7 miles giving him the guided tour. Here’s the group about halfway through the first loop. Y’all will get used to seeing this barn. It’s a real landmark on our trails.

April 6th Social ride. There are three participants not including myself who are not in frame.

Late in the ride I had a bit of a spill. Honestly, after a couple of days, it didn’t feel that bad. The only real problem with it, is that I still can’t explain how it happened. You know those old cartoons, where someone pulls the rug out from under someone, and they go completely horizontal, and come crashing to the ground? Well, that’s what happened. I was riding into a switchback, and *boom*, I was laying on the ground. No idea. But that brings me to a tip. You’re thinking, hey, weren’t you carrying ¬†a camera? Yep, I sure was.

The camera I carry on my rides isn’t something I’d get all broken up about if it got destroyed in a fall. Still, who wants to break a camera? I carry my old Canon Digital Rebel XT. I have a gizmo called a Capture Clip (Peak Designs) on the strap of my Camel Back. I can get all crazy and bunny hop stuff and jump things with the camera on this thing and it doesn’t smack me in the face or anything else. It’s pretty sweet. Even sweeter is the fact that in this crash, it not only held the camera, but again, the camera didn’t hit me in the face or anything, and when I stood back up, the camera worked. In fact, I carried with me the next day at Rotary. When we, you guessed it, did trail work.

We’ve had a trouble spot for some time where the trail is on flat ground because it has to be. It’s the lowest spot on this bit of flat ground right before you get to the creek. So when it rains, a bunch of run off from where a pump station was put in flows off the hill and onto the trail, and sits there. That’s a problem. Here’s a picture I took (with my camera that survived my strange spill) of the solution, and the four guys that worked with me to help finish out this somewhat drawn out project.

These guys worked super hard with me April 7th to get this turnpike finished. We did in one day what would have taken two days on either of my other work days out here. Bravo chaps. Bravo.

You can see an old section of turnpike disappearing out of the frame at the back, and the new section extends to where I’m standing to take the picture. It’s a lot of work, but it should allow water to pass through in a few places, and run further down to a low spot with a lot of drainage into the creek, keeping the trail from being wet and muddy after rains. We’ll find out today I guess.

Anyhow, that’s what I’ve been up to, in short. I’ve got a full day ahead, that includes another Saturday social. But first, I have to go haul a couple of tons of gravel for a friend….

Patches, tubes, and other flat solutions.

A couple of weeks ago, I managed to get a ride in on some trails with a friend. He doesn’t ride a whole lot, but he keeps some pretty nice kit. While we were out he got a flat. It was a classic pinch, and he pulled out another tube, said he’d patch that one later. Unfortunately, the extra tube he was carrying around had been in his pack for a year or so, and it split when he pumped it up. It brought to mind an issue I think about sometimes.

Typically I don’t carry a tube with me when mountain biking. When on a road bike, I always carry a tube, but I’ve had this same thing happen where the tube basically dry rots in the pack. Of course, I always, regardless, carry a patch kit. I think maybe the difference for me between mountain biking and road biking is that I can patch the tube sitting in the woods, and the worst I have to worry about is what, a passing cyclist, or hiker? Ok, maybe a bear. At the same time, I’m not keen on sitting on the side of the road for any length of time. I mean, you just never know today, right? Especially when it comes to people behind the wheel.

On the flip side of that, when I went riding with my brother over Christmas, he stuffed a tube in my pack. Now, he has miles of mountain bike trail to get lost on, and tubes do come in handy sometimes. It’s not like he’s in one of my local parks when seven or eight miles of trail covers the whole loop, and it takes at max a mile or three to get out of the woods. If he can’t patch a flat he has to hike 10 or 20 miles sometimes.

So, I’m taking to carrying a tube with me now on my mountain bikes as well. I’ll just have to be more cautious about how long I carry it around with me, otherwise it’ll be useless. Speaking of useless, I was riding with a friend who got a flat and pulled out some of those new glueless patches. That held for about 3 minutes. As near as I can tell, those things are horrible.

So what about everyone else? Tubes? Patch kits? How do you feel about patching a tire on the side of the road? In the woods? Let me know.
