Recreational Cyclocross and Gravelbiking This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

Cross Wheels vs Road Wheels Question

What (if any) are the key differences between a _wheel_ intended for road racing and cyclocross?
Are they (or some) interchangeable?


Thanks!

From what I've found, typical cyclocross wheels are a little beefier and a little heavier. They are a little wider to accomodate wider tires. I would say you could use cyclocross wheels on the road with no problem, but I would hesitate to use road racing wheels on a cyclocross track. If not doing any cyclocross racing or off roading, a road racing wheel would work fine. I just don't think an expensive racing wheel intended for road use would be wise to use to race cyclocross.

Thanks knobster - thats basically my question.
Im purchasing a cyclo cross bike, however I dont plan on doing any serious off roading or racing.
I was considering getting some nicer racing wheels.
So I wanted to know if those wheels, coupled with a cross tire, would be ok for 90% road, and 10% general offroading (hardpacked dirt, etc) .
It looks like you are saying thats not a good idea.

Anyone else have any thoughts on doing this?

Go to any race of significant size and count the number of ultralight carbon tubulars. Some are rebuilt with more spokes, but many are not. Fewer spokes means less mud build-up.

Rim diameters are generaly not any wider than any other road rims, cyclocross tires are usually in the 30 to 35 mm range. Even if they weren't, I've run a 45mm tire on a road rim without issue.

That said, for non-racing purposes I wouldn't want to use a super light wheel for all of my riding, on road or off.

Lightweight road wheels will be fine. I would avoide a cyclocross race tire for the riding you described, however, because their performance is usually mediocre on road, they wear extremely fast, and offer very litle flat protection.

When you say 10% hardpack dirt/general off road, how technical do you mean? If it's just packed dirt roads and the like a 32mm touring tire may be your best choice.

Im plan on doing mostly road riding (pavement). However in my area there are many trails like this running along rivers that I'd like to have the option to ride on.
ie, simiar to what you see in this photo (it's big)

I'm considering picking up a pair of road wheels with few spokes, and wanted to know if they will hold up riding on something like above.

M_S - you said one thing that confuses me "I would avoide a cyclocross race tire for the riding you described ... and offer very litle flat protection"

I was under the assumption that (typical) cross tires were much better than road tires WRT flats - that is you wont get them as often. Is this not the case? Or when you say "cyclocross _race_ tire", you mean something different.

Thanks for quick, replies.

32-35c touring tires will work fine unless you're really out for a soft ride. Although the lines you need to take get pretty narrow, I've actually gotten through a few of the easier mountain bike trails around here on touring tires.

I wouldn't hesitate to use any of my road wheels for cyclocross racing but they're all meticulously tensioned and all have a reputation for durability. However, I would hate to taco a Ksyrium Elite if I was just tooling around town and missed a curb hop. Repairing an Ultegra/Open Pro would be much easier and cost half as much.

There aren't very many broken beer bottles on the typical cyclocross course. Some cross tires do better than others but their design priorities are often associated with being grippy and fast and they don't last for very many miles when put to pavement duty either. Touring tires are made to stand up to steel belt remains and the miscellaneous "flotsam and jetsam" that ends up on the side of a busy road. I've flatted just once in 3000 miles on my Vittoria Randonneur Pros. It was an inch long staple. I flatted my Ritchey Speedmax's once every 800-1000 miles and AFAIK they're better than most cross tires for road duty.

I don't get it.

Other than some blind urge to modify the bike somehow, I can't see the point of replacing the wheels. You say you won't be racing so you want to buy some racing wheels. Low spoke count wheels are either weaker, heavier or much more expensive. They must be one of those three, you can't get something for nothing.

I see no advantage to getting the weaker or heavier ones, and by the time you put on tires that can handle the off-road stuff the really expensive ones have lost some of their advantage.

The conventional wheel has had the advantage of about 150 years of continued development and improvement. You'll have a hard time doing any better.

That trail picture is nothing. Well, actually it looks like a nice place to ride but if that's as bad as it gets then just a thicker road or touring tire would do you fine. I wouldn't think twice about running my 700x23 tires on there (well, my rear end probably wouldn't be happy due to the lack of cushion but I doubt the tires would care much). And any decent wheel will get you through that without problem.

My '03 Fuji cross has an Ultegra/Open Pro on the rear and the original Ritchey OCR on the front. I relaced the front last fall on my own and tensioned it by hand and trued it using the brake pads as guides. I then took it out for 12-15 miles on mountain bike trails (easy stuff for a full suspension mountain bike but still full of mud, gravel, some log crossings, ditches, roots, etc.). Both wheels were just fine. I've got Ritchey Crossmax 700x32 tires. I would have liked more grip on some of the muddy uphill grades but other than that it works great.

If you are considering getting new wheels for the road, then get the best you can afford and use the original wheels with fat tires for the trails. Or, just use the wheels you've got and see how they do. I think that most wheels other than super-light high-end road race wheels are much stronger than you expect. A hub, spokes, rim and tire do a great job of distributing forces as long as they are set up well. Just look at those old movies of Model T Fords rumbling over primitive roads with wooden spoke wheels.

+1. I would ride my 700X23s on that with no hesitation. You should see the stuff I take my Mavic Open Pro's/ultegras on with simple 700X32 Michelin Transworld cities. I am no pro but I on my lunch ride last week I was clearing stuff that guys on mountain bikes were falling down on behind me.

Here is a link with a picture of the mellow but crazy steep part of the area

A decent road wheel should be pretty tough if built well.
