Carbon tubbies vs decent clinchers?

[Butterbean]

No experience with tubbies, but I've stopped worrying about training/racing wheels, etc etc. I'm riding some Chinese 38mm rims. Didn't cost the earth, and since I important them myself, they were even cheaper.

 

 

They're so good tho, I never take them off the bike. Sold the training wheels and haven't looked back. Ride them in all weather, all day, and they run along happily. They ride beautifully well under my 115kg heft, and in three years, I've trued them once after the initial truing I took them for when they came out the box.

 

Couldn't be happier, and it's so nice to not have to worry about your wheels or choice or pads or nonsense. Just ride.

Carbon rim brake clinchers are not a good option. The braking surface is right by the clincher hooks. The heat buildup is enormous. The clincher hooks go soft and this can lead to failure. If this happens at speed you know what could happen.

Are you suggesting disc brakes then?No heat build up on the hooks.

 

Or rims with an aluminium braking surface?

What alpine mountains are you descending in South Africa that you are concerned about overheating a rim?

 

OP, as many have already said, sell the tubbies and get a decent set of clinchers - you won't look back. Tubbies used to be the only wheels to race on, but with all of the modern designs / upgrades, clinchers tyres are fast approaching tubbies.

Also note that Peter Sagan raced tubeless clinchers over the weekend ....

are people aware this question is nearly 2 years old?

Nonsense

Here is an interesting video on carbon wheels. Worth watching.

Nonsense

 

I melted my front wheel at Ladysmith Race about one third the way down De Beers pass. So they fine, but not for down hills with a lot of braking. They all have this problem.

All European pros disagree with this statement.

that said. they get new wheels nearly every season

Also the option of tubeless, although my concern is they dont really seal in the event of a puncture and you can't plug them. Plus the sealent needs to be checked every few months. 

 

Then there are thermoplastic tubes like Tubolito, lighter and more puncture proof than normal butyl tubes. Albeit at a price.

What brand was this @MartinPJ

What was your weight at the time, roughly?

Check this study out. The results indicate if you brake excessively on any clincher you could have a serious failure.

 

Maybe pros brake less than normal people. I weigh 70 kgs. The wheels were some chinese no name brands. They failed in about 1 minute of hard braking. They were three years old ridden continuously.

The no name brand was clearly sub-par in terms of quality, RnD based product

I imagined you were 103.634 kgs ????

True. But I loved those wheels nonetheless. The torture testing of carbon clinchers shows that they are easier to destroy than you would think. I would keep my carbon beauties away from super mountainous races.

I’m a Mavique fan

The top brands in the world hold up well with the toughest races in the world at WT level. Even in the 40 plus temps of Adelaide ????
