Tubeless and sidewall cuts? - Cyclocross Magazine2024-03-29T11:07:45Zhttps://cowbell.cxmagazine.com/forum/topics/tubeless-and-sidewall-cuts?commentId=1198434%3AComment%3A106945&feed=yes&xn_auth=noUPDATE: After two races on th…tag:cowbell.cxmagazine.com,2011-10-20:1198434:Comment:1139882011-10-20T01:58:10.267ZJ.D.

<p>UPDATE: After two races on this set up, it's working pretty good. I'm getting great grip on the grassy off-cambers and pretty good grip in the greasy-mud-in-the-grass sections. However I am going to have to bump up my pressures a bit as I burped the front pretty good on the first lap of my second race last week (coming down hill in to a couple of S-turns that if you had the grip, you could really rail. I was getting the hang of it and I think I pushed the front a bit too far). Head to pits,…</p>
<p>UPDATE: After two races on this set up, it's working pretty good. I'm getting great grip on the grassy off-cambers and pretty good grip in the greasy-mud-in-the-grass sections. However I am going to have to bump up my pressures a bit as I burped the front pretty good on the first lap of my second race last week (coming down hill in to a couple of S-turns that if you had the grip, you could really rail. I was getting the hang of it and I think I pushed the front a bit too far). Head to pits, change wheel. Several laps later, the rear burps once on a less-than-graceful remount and then again on a pothole-type hit. Not wanting to give up the position I had just gained I finished the race on that tire instead of pitting and it held pretty good - at 20.5 lbs of air.</p>
<p>So next race I'll air up a bit more. As a bonus, I had indicated to my wife that I had flatted. She, not being very technical minded nor much more than an occasional rider, pumped up the flatted tubeless while I was racing in order to have it ready for me should I need it again with no inspection. It's still holding the same amount of air she pumped it up to. You can't even do that with a regular clincher without changing tubes. Wow.</p>

<p>I'm about 180-ish, and right now I can go with 27-28 lbs. up front, 29 in back. I can drop a few lbs. if it gets real muddy and isn't too rocky. I'd like to go with wider rims but Fulcrum 7's are what I have for now. I have found I can go about 25 in the back but I start to burp air a bit and pluck grass. Less than 24-25 up front and it will start to get too squirmy and the sidwalls will fold.</p>

<p>After reading others responses to air pressures in general it seems a bit low. And no, I'm not known as much of a finesse rider. I'm more of a bull-in-a-china-shop type rider. I may go up a bit when I start with the serious practice and/or racing. But for now it seems a good starting point.</p>
<p> </p>
<p>And perhaps I've overstated it a bit with the 20%, I was kind of gauging it on the "core" group of guys I've gotten to know. But it's still a lot more than I thought.</p>

<p>thanks JD for the follow-up. that's awesome. that's really fast, light combo - one of my favorites really. that cross blaster on a wide rim is great - sub 300g tire. the cinder-x has a similar tread and is wider, but the casing/bead make it much harder to seal, fwiw.</p>
<p> </p>
<p>what pressure did you go with, and how much do you weigh if that's not too private?</p>
<p> </p>
<p>20% of the racers? that's amazing.</p>

<p>Thanks, Andrew. It was your three-part series that gave me the gumption to try. Now I find out about 20% of the guys in our series are going or have gone tubeless.</p>
<p> </p>
<p>With the advice above, I went with a different tire to complete my setup (CrossBlaster up front, Kommando in the rear). Taking it out to my "training grounds" I've got the tire pressure pretty dialed in. And after several days of not using those tires I went back and checked the pressure and guess what - no loss.…</p>

Hey, tubeless works! And I never thought I'd get a tire with so little tread to grip in the mud and loose stuff so well.</p>
<p>Thanks to CX Magazine for giving me the idea and tools to get a successful tubeless setup going. I'm pretty excited to start putting them to use.</p>

<p>i agree, I wouldn't race it unless it was a small cut, and thus you probably wouldn't need a boot in that case.</p>
<p> </p>
<p>As to tubeless in cyclocross, FWIW, I'm personally a huge fan of tubeless in cyclocross, and if forced to choose to ride and race one setup for the rest of my life (thankfully I prob won't have to), I'd choose tubeless over clinchers or tubulars for cyclocross.

The OP asked about using a patched tire in a tubeless setup. Chris was nice enough to reply with good advice. I know him from local reputation and results, he's too modest to say so , but there are few on this forum with his level of skill and experience, so take or leave his suggestions as you wish. Whats with the attitude dudes? It's just tires, roll what you bring and don't worry about the other guy's rubber. Chris' advice is solid if you're not too proud to learn something. <br/>

<p>Seriously, I run both road and cyclocross with tubeless setups and will never go back, and don't understand why more people don't see the light. I have not flatted once in 3 seasons of road and cyclocross racing. Tubulars are an expensive option that not everyone can afford. And if someone is anti-tubeless they are usually the riders who turn their bike upside down to change their tire or take their bike into the LBS to have their derailleur adjusted.</p>

Yes, it can and has been done. I'm the sort who would rather race on a new tire though. Anyone who says tubeless doesn't work for cyclocross doesn't know enough about tubeless, period.

<p>I don't know any MTBers telling 'crossers anything, much less that they should run tubeless. I don't even know any 'crossers telling other 'crossers to switch to tubeless. I would like the tubular faithful to stop telling those of us who choose tubeless that tubeless won't work. It does, if it's done right.</p>

Tubeless technology is mature and works quite well for MTBing. Not so well for 'cross. To reverse that, tubulars are the best option for 'cross and you don't see crossers telling MTBers they should get tubulars.
