Newbie wheel question(14 posts)

Newbie wheel questionmasongsp
Nov 11, 2003 6:09 PM
Hey gang,
First I want to thank you guys for the help (you didn't realize it, but I've been lurking for a few months). I'd consider myself more of a tri-geek - sorry ;-), but picked up a cx bike (Ellsworth Roots) about a month ago and did a couple of races - much fun!

But now I've got a question. The wheels that came on the bike were Spinergy Rev-X. I was a little concerned with the Rev X's from a durability standpoint, but remember seeing pics with guys using them. Is this a wheel that is cross worthy? (most riding will be on gravel roads or rail trails, though) Also, in doing a quick search, I came up on a thread that these may be illegal to race with anyway.

What's the deal with the Rev X? Are they ok for cross or should I be using them for tri's?

Thanks,
Brent

From a fellow tri-person ( I hate the word 'geek') racing their first 'cross season, welcome!

Sounds like you picked up a pretty awesome 'cross bike. Rev-x's will be fine (as long as they stay true). I see more combinations of all kinds of components in 'cross than anywhere. It's a hodge-podge of whatever is allowed. Unless, of course, you get into UCI sanctioned races of higher categories. Then it's no mountain bikes, double triangle frames w/drop bars, etc. But to be sure, contact your local series representative. It's worth the call ahead of time rather to drive and be turned away.

Oh, and if your just looking for an excuse to get another set of wheels, here's one - flats and feet in spokes are common. a spare wheel is VERY handy.

Tubular with Dugast Tires was the wheelset of choice for the top pros in the 90's. I'm not sure of any rulings against (UCI) they'll do fine in local races.

As ATP says, these were the hot ticket for cyclocross not too long ago. They've been largely supplanted at the top of the heap by deep-section, wire-spoked carbon wheels (Zipps, Reynolds & the like), but that may have more to do with availability, weight, sponsorship and other issues other than any problems with the Rev-X.

Any deep section rim will have some advantages in a cyclocross race; the most obvious is that the rim itself is very strong. Less apparent are the benefits in mud -- the deep section wheels will track better in deep mud or sand (kind of like a keel on a boat) and shed mud better once you're clear of it.

Taken to extremes, though, it becomes something that has always puzzled me to see every so often in cyclocross: the use of disc rear wheels. I'm not talking about disc brakes, I'm talkin' the fairly heavy, carbon fiber, uber-Aero, tri... uh... person rear disc wheels. You'll usually see at least one or two show up at World's, though almost always on the back-markers getting lapped by the leaders. Leaving aside the logic of bashing an $800+ wheel around in the dirt, I see plenty of disadvantages -- weight, lack of lateral rigidity, to name two -- and no conceivable advantage whatever. Aero benefits when you're going to be racing between 12 and 20 mph, pushing a knobby 32c tire through the air? Uh, no.

Cheers!

I asked another guy at the race. Said "They probably have these around from other bikes" and "They won't catch a stick and ruin the deraileur". I'll buy argument 2, but barely.

Things that make you go Hmmmmmmmmmmmmmm.

The UCI had a cow over the sharp edges on the RevX wheels a few years ago and banned them. No bueneo for UCI races, but OK for USCF races.

For the speeds that we race in the lower categories I don't know that aero wheels are that much of a benefit. You're probably better off with a lightweight wheel till you get to the upper end of the Bs or the As.

Keep an eye on those spokes. If they break, they do it catastrophically.

perhaps someone needs to go running through their office with scissors in their hands... seems a bit anal to me, especially the whole disc brake deal.

Brakes just slow you down anyways, the whole point is to go fast...

screwy rules but at least they are consistent. If they banned Rev X for this reason it makes what I was pondering about the discs make sense. I can understand it in a UCI race where you may have 50 riders going gangbusters into the first set of barriers, most likely why they are still allowed local. not nearly the #'s and therefore a lower probablity of damage

If you look at this exchange it would appear that:
1) Disc-brakes are not banned, they've just never been approved.
2) It's unlikely they would be approved because disk-brakes are a mountain biking technology and do not come from road cycling and the UCI desires to preserve the distinction between cyclocross bikes and mountain bikes.

understand. but then why the ban on the Rev X?
This was THE wheel.

Michele Bartoli. Was, maybe still is, the heir-apparent to Museeuw as the best classics rider (although he's getting old now and Bettini has eclipsed him in the last couple of years), anyway, he was involved in a crash in the Tour of Germany (?) 3 or 4 years ago and stuck his knee into a Rev-X. It shattered his knee cap and largely severed his quadriceps tendon, I believe the ban of these wheels was a consequence of this incident.
thanx...atpjunkie

so it was a 'sharp edges' in that case. It makes sense as gap between 'spokes' is quite wide.I've heard of racers losing fingertips trying to adjust a computer sensor, I imagine a Rev-X could get a bite of the whole hand

You can use them. I have only seen one or two guys use Rev X wheels in the Norcal area. The one guy that I raced against, busted his back wheel when he didn't clear a curb; the wheel just folded up under him. But, if you work on your technique and use the wheels for courses where the surface is mainly grass then you can use them.
Thanks to all!! *nm*masongsp
