So I am riding The Crusher in the Tushar in less than 2 weeks. I have been struggling with my tires. I used Clement X'PLOR USH 35mm setup tubeless last time. I have Stan's rims. They worked great, but I am not sure if these tires are supposed to be used tubeless...I used them for a couple of years and the front tire started bulging so I replaced them with Gravelking SK 35mm tires. I love the tires and they look like they will be perfect. However, the rear tire is rubbing on my rear brake cable mount.
These tires must be wider than the 35mm they claim to be. If I can't get the rubbing problem solved...what tire should I replace it with? I could always size down to the 32mm gravel king sk...can those be setup tubeless as well?
What do you suggest for my rear tire? Must be 35mm or less and tubeless ready. The race is 70 miles - half dirt/gravel and half road. 10,000 ft climbing.
The cable mount is on the top of the rear chain stay. It only rubs when I pedal and the wheel flexes, but it is sure going to annoy the crap out of me and everyone around me for 6 hours during the race.
Put the cable on the outer side of the guide and zip tie it a little further back inline with the rim. It should stay no problem. \n\nIf it still rubs just file some edge knobs off the tire. You won't be doing any leaned over turning that far on the crusher.
If it's just the rubbing you'd like to fix I would agree with the above two responses. My initial thought was the same as Oilcan's.
I've not done the Crusher though it's a ride I would like to do sometime - perhaps next year. So I'm not familiar w/the course. Regardless, I prefer to ride tires that are designed to be run tubeless. And I'm a big fan of Schwalbe tires - including Nobby Nics on my mtn bike, Pro-Ones @ 23c on my road bike and S-Ones @ 30c on one of my gravel bikes (Ridley X-Trail). I also have used the Pro-One @ 28c on the Ridley for the Belgian Waffle Ride - also a mixed road/trail ride though more road than trail - and they were great. I have a set of G-Ones @ 35c that came on my Niner but have not tried them yet - for the future. Finally, I also ride a set of Nano 40C TCS on my Niner and like them a lot.
The USH @ 35c you have are not tubeless - I don't think Clement make USH in tubeless yet. Clement did just come out with the MSO in tubeless at 36c so that could be an option if it fits. I'm not sure what you're maximum tire size is for your frame but it sounds like something around 35c is the max. I've had great success riding the S-One so far - a very capable tire though not sure if it's suitable for the Crusher or not as it could be a little small. As stated, I've not use the G-One as yet but I would think that might be a great option for you. Finally, there are a lot of tubeless tires in the 33c size as that's the UCI cyclocross maximum size. That would split the difference between the 35c and 30c sizes.
Note that the Stan's rims are not always compatible with many tubeless tires. They have a slightly larger rim diameter that was originally designed to help non-tubeless tires stay seated and hold air. So maybe your non-tubeless option is a good idea for these rims.
Is the wheel dished properly? Also make sure your wheels are centered in the droputs and measure the tire width at its widest point, I have Kenda flintridge 35's that measure almost 40. If the rub isn't too bad then I would put a marker on the mount, white shoe polish or similar, ride the bike till it rubs and note which knobs are hitting and the location of rub on mount. Then I would proceed to file down the knobs and or mount with a dremel or sandpaper depending on the severity of the rub.
Clement 700x35 USH are my favorite all around tire. I have about 1000 miles tubed and now about ~400 mi TL using homebrew with no issues, just some air loss over non use days. I really like them a lot Tubeless. I have a set of Schwalbe G Ones I am postponing installing because of them.
Good news - had the wheel dished over 3mm and problem solved. Guess I need to find a new bike shop - I brought it to a shop twice and both times they told me it was fixed. Found a new guy and I'm glad I can keep these tires. Should be perfect for the course.
Hey Ed, Were your Clement USH's 120 tpi or 60 tpi? I am tubeless with the 60 tpi and they work well but I am kinda concerned about that bulging now. The sidewall on the 60 seems pretty beefy to me.
I got the 120 tpi tires. It is a bit concerning my front tire got that bulge. I commute only a little over 2 miles each day on asphalt.
I tested the gravelking sk tires yesterday and there were fantastic. Did a 70 miles ride with 10,000 ft of climbing. What psi do you think would be optimal for a 50/50 asphalt/dirt ride? The dirt sections will all have steep ascents and descents. Not sure what the condition of the course is, but there is potential for some nasty washboards and loose gravel.
The ride I did yesterday was mostly asphalt with a few short dirt climbs. I ran about 38psi...thinking I can go lower than that. I am 175 pounds and running the 35mm tires tubeless.
These tires are holding air much better than the clement tires were. I had to pump thise up every other day. These are holding air for several days without needing to be pumped up.
