What's the consensus on carbon clinchers, seriously?

Everything about building wheels, glueing tubs, etc.

My son has been bugging me for carbon clinchers. As he races, on great wheels I said no - train on your alloy ones. Wed he had a blow out and messed up his pretty alloy clinchers - looks only, they work fine. Carbons would have been ruined.

Prior to the the race I had put about 200 miles on the tyre/tube/wheel combo including a 6 mile warm up on the day. If the tube had been installed incorrectly it would have exploded prior to this race. On inspection of the latex tube it had a three inch gash where it had exploded and ripped the tube open. It also destroyed the tyre.


I'm not claiming that you are making anything up... but that you are misinterpreting the cause of the problem.

Do you understand that a tube cannot possible "explode" unless its container fails? When the tube is properly installed, it expanded a small amount (even at high pressure) and pressed up tight against the tire and rim bed. If the tire or rim bed fails (suddenly) to contain the tube, then it can explode. You keep saying that the tube is the issue... but it couldn't be. It is either poor installation, or something wrong with the tire or rim.

Also, latex can in fact survive in a pinched state for a long time, and the explosion occur while riding when extra heat or forces are invloved.

If it's a road disc bike, is there any good reason to use an aluminum clincher over a carbon clincher? Besides costs (and costs is a rather weak point considering the prices of imported Chinese goods these days).

tried a carbon clincher. it was ok. but i could have built an alloy wheelset for the same weight.
if you wanna go carbon, go for tubulars. its that simple.
but if you get a flat, you better be prepared to carry a set a preguled tubular tire.
some even put stans inside thier tubular tires.

But with carbon you can get a more aero wheelset at the same price. For the aeroweenies ;)

Carbon road clinchers haven't yet been made significantly lighter than light aluminium rims (though there are some light carbon 29er MTB rims that can't take road pressures). But they can be made deeper. You can't even find a 50mm deep aluminium rim let alone a 50mm deep clincher that weighs 410g.

how about ride quality ? I think my carbon clinchers are far more comfortable then my Al rims...

If there's any difference at all, carbon clinchers are a bit harsher than aluminium rims with the same tires at the same pressure.

Tire model size and inflation have much more of an effect on ride than the rims. But the deep section carbon rims are stiffer than aluminium rims. I think that is the source of the very slightly rougher ride.

I am very satisfied with my 2012 J-Bend spoke Reynolds Thirty-Two Carbon Clincher

Had Reynolds Assault before (sucked)
Tried Zipp 202 Tubular (well roads are bad here, made a few flats and sold them.) Spare Tubular weight is not worth it.

One of the lightest clincher rim at the moment is Ryde Pulse comp Disc 330gr and it is alloy rim! Only for disc brake. I haven't seen this made with carbon yet.

Tubulars own descents. Anyone stating otherwise is a fool.


We get it, you're a tubular apologist. That said, you've not actually helped any reader on a consensus about CCers, anecdotal or not.

Personally, I think alloy is better especially when one considers braking, and the cost of carbon pads. If one really wants the lightness of Carbon, then Shimano's solution on the C-24 is the way to go ; carbon with an alloy strip. Carbon is a wonderful material, but it's not the best solution for every application.
