Are new bikes all this fragile?(15 posts)

Are new bikes all this fragile?flying
Jun 7, 2002 12:18 PM
I am about to order a Ciocc Challenger
This is my 1st multi material bike. Alum with carbon stays & fork.
I was just told by the distributor.....

""As regards warranty, it is two years but we must insist that tyre pressures
are used at not more than 7bars (101psi) and not less than 23mm. Your body weight
must also be less than 80kgs.. If you use tyres at greater pressure, there
is a very good chance the frame will brake through high stress resolutions.""

What??? I mean I am 155# so no prob on the weight but,
I ride Vittoria Corsa CX's tubulars always have. they are 21mm wide. I also run them at a conservative 120psi or 8.2 bars.
Is this indicative of all the new bikes of this style?
I mean I find it really hard to believe thay are this fragile.
If this is the case I am better off sticking with my Colnago MXL.
Let me know what you all think/know about this.
Thanks

If a maker put that in writing, I'd not ride that bike. The tire pressure part is particularly troubling. Many tires require a minimum of more pressure than that.

I'd send it back. That's crazy. If it's really that fragile, what happens when you hit a pothole, sprint like hell, or jump a cattle guard?

Thanks Doug,
Luckily it has not shipped to me yet.
But your thoughts mimick mine.
The tire pressure is the worst in my mind too.
Not too mention I do jump cattle guards. Not that I have to but also as you say..."If its that fragile"

Crapola I was really excited about it too.
Thanks for the input.
Just order their non carbon stay optionelviento

No weight penalty and saves a few hundred bux. Won't look as sexy, so it's your call.
Hmmm...PODIUMBOUNDdotCA

I agree with Doug.

Although it could just be the maker just wants to be overly cautious. But at the same time if they are that cautious it means they don't completely trust the carbon/aluminum joint so I'd send it back. If you want a smooth riding bike you may have to look elsewhere. Carbon/aluminum seatstays are still pretty new so their long term longevity has yet to be determined.

Good luck with your decision,

go with your first intuition..zooog

stay away. Sounds like a great bike but with all the "warnings" I think your first thoughts are your best..stay away.

It's Ti, but you might consider a Seven Odonata. It's pretty pricey, though.
That's bullNo_sprint

Don't believe a word of that. That bike is just as solid as any other alu with carbon stays. A friend of mine is on one, has been for a year or so and he loves it. Says it's nice and stiff too. He's around 170 and 6 feet.

I've also ridden one and felt it was quite near any other alu w/carbon stays I'd ridden.

pick two.
If they're that worried about it...hayaku

I would be too. There is nothing worse than having your bike fail on you. I'm not a fan of the Carbon seat stay idea anyway, this adds to my sceptisism.

you could ask a dealer for other aluminium/carbon bikes if they have such asinine restrictions. my friend's Scattante Airplane didn't come with such restrictions, but he's ~140. personally, unless you're really set on that bike, I'd just give them the finger and find something else.
Sound's like you bought into a problemDaveL

I'd cancel the deal if I were you. That bikes too fragile for me.

Actually I did cancel the deal.
Then he wrote me this note....

if you use such extreme tyre pressure, it would be unwise for us to sell you
any lightweight alloy frame, so i will cancel your order

hmmmm I guess Im stickin with my MXL which is fine & I was keeping it anyway. But I wanted to see what a 16-17lb felt like climbing.
"extreme tire pressure"DougSloan
Jun 10, 2002 6:15 AM
120 psi is not extreme. Holy cow, on what planet does this guy ride? I'd say over 160 psi is "extreme."
The weak link is the Dedacciai SC 61.10 tubing, not the CF staysTig
Jun 8, 2002 7:30 AM
The CF stays they are using are far more durable and over built than the rest of the frame. How can anyone blame them when the bike is made of super-light Dedacciai SC 61.10?

Check out the steel Ciocc EOM Carbon if you gotta' have a light Ciocc with CF stays. It only weighs 1/3 pound more.
