    Wear out handmade sewups in training?

    I got a sweet set of Challenge Grifos and love em. I have a yard trail I love to practice on. I can't hardly make myself practice on my nasty clinchers. The trail is soft grass, leaves and loam. It SEEMS like it's actually making my tires GROW nicer with every session. But maybe I'm confused and I'm just wearing them out. And will be stuck racing my nasty cheap clinchers come next fall. Should I spare the sweeties some this spring? Will they last a pretty long time? I used to be a roadie and pavement eats tires, especially soft ones. In short: how many miles can expect to get outta my nice sewups on a soft trail? Each lap is 1km...

    Not being able to see the future.. seems a better conclusion is to keep data, now

    and see in retrospect how long they did take to wear down..


    Might be a weaning time to train on them Tufos, again..

    I figured Challenge Grifo wear rate would be a known item, given that others have ridden them before me. Also, others have spent much more time than me on various kinds of trails and might know how they affect tires.

    I just have one Tufo and it's holding strong with my crazy repair! It's part of another experiment which is to convert my gofast roadbike to a CX bike so I will be riding that some and seeing how that goes.

    I suppose I'll give the clodhopper clinchers a try again as well -- they're cheap Maxxi 35's (Ritchey? Speed?), as I recall, but I haven't looked at em in awhile. Maybe I can now have some fun with them trying to see how soft they can go.

    It may be known, but may be amongst racers that have other priorities than post here..


    maybe there is a dutch/flemish language site, for that in group. IDK..

    I'm surprised that tire durability would be an exotic topic, but we'll see if anyone chimes in.

    I was wondering about that. It seems a bit weird. Cyclocross is a kind of racing. Hmmm... But I guess it's also a kind of riding ... which kinda always relates somehow to the racing. Anyway, my question isn't really race oriented. It's just about tire wear. But I'll check out the race sub-forum. I wonder why the split-up...

    There are too many subjective variables to make a meaningful quantitative statement. I suppose on a road bike you could say "Tire X will last roughly Y miles" but even then it would depend on whether you rode it in the rain, on sketchy roads, etc.

    Given the extra expense and maintenance associated with tubulars, nearly every non-sponsored racer saves them for race day or for race-specific practice sessions. The owner of one of our local shops used to ride his tubulars on his weekday practice loops during the season; then he flatted during one of these sessions and went back to clinchers like the rest of us.

    The day before a race, I'll clean up the bike, swap the clinchers for tubulars, and ride to the local park for about 20-30 minutes of test riding. During the off-season, they hang up in the bike room.

    Good clinchers exist. IMO Michelin Mud 2 and Maxxis Raze are great, reasonably priced tires you can ride every day, and you can find deals on eBay.

    This section is a dominated by people that want to know about the bikes , because they are a popular.

    a fatter tire road bike.. can I tour on it? will this make a good commuter, etc.


    Yea put the clinchers on it , and practice the barrier jumping.

    if you can get off and back on without losing momentum, that, at least, should
    keep you in the same lap as the top 3. win, show and place..

    Çan you even still get a price break on Tubulars when you buy them in lots of 10 or 20?

    Yeah, I'll prolly switch back soon to my clinchers.

    Lots of 20 tubies? Yikes. I just swap stuff for the occasional sweeties that I can. I could never afford to buy one of the good ones straight up. But I do have luck swapping with those who've gotten out of it. We'll see if I can keep up with my habit. Heck, I'd only go thru one set every year or so when road racing. Back then buying the good ones was economical -- they lasted multiple times better than the cheapies. I might see about getting some bargains on good clinchers. Maybe my appreciation is now strong enough to last the 'deflation' of using semi-lame tires.

    PS: My clinchers are Ritchey Speedmax 35's -- seem like a dry fast course tire from what I know now -- kinda fine tread on top -- is that a CX file tread? I guess my local courses are pretty dry and fast so maybe they'll be fine. ...Enough. For now. Let's see how bad I miss my sewups once I give these clinchers a try...

    I don't know about the Grifos, but I think I'm seeing tread wear on my Michelin Mud2 clinchers after around 250 miles. Like flargle said, I would think the risk of serious damage is a bigger issue than tread wear. Having heard the way guys grumble when a nice new tubbie gets ruined in a race I can only imagine what they'd say about ruining one while practicing.

    Ah, interesting! I didn't think about other damage. What kind of things happen? I suppose cranking turns at 25psi puts different kinds of stress on a tire. --Altho my yard trail is mellow. I'm not so worried about punctures.

    Treadwear with soft rubber in 250 mi's -- interesting datapoint.

    Wear them out. Every day you kill them by a dime or a quarter or a dollar. But how much fun is that sixty four cents of damage when you have a really sick set of tires??

    It's like, at least three bucks of fun, no doubt...

    True wisdom!

    Life's too short to ride bad tires.

    ...But I'll still do some experimenting. This CX stuff has me fascinated. I'm going to try 32 tour clinchers on my yard trail and see how that goes. Maybe road tubulars, too. And my nasty old CX clinchers, file tread. I'll probably just learn that I should just ride sweet tires, but ya never know. Fun comes in many stripes. In CX my hunch is that the fun might be surprising.

    The best my bike has ever felt on the road was with 25mm Tufo Elite Rides. Obviously that's not for CX season though.

    Are you going to race?

    When I was fast my heavenly road tires were handmade Vitt CX sewups. Now I'm slower and do a wider variety of riding so I find that different tires stand out as beautiful in different settings, incl plump clinchers like Vitt Dynamics for dirt roads at 55psi ... sometimes.

    I look forward to giving all my CX setups a chance to shine. So far the sewup Grifo's are pure heaven. (I have a line on a further nice variety of CX sewups that a guy has who doesn't use em anymore that I can hopefully barter for.)

    I do a few races plus enjoy the training on my yard trail. I only just started last year so who knows what'll happen.

    I do still want to be able to use these Grifo's next fall, so I don't wanna wear em out this spring/summer, etc., in training.

    I find tricky courses to be fascinating and might end up playing around more with course-play and designing.

    (I also really like XC ski course designing and canoeing on tricky, obstacle-filled rivers where you dismount the boat a lot and try to be smooth -- I have a nice, light 25-lb solo boat.)
