Road Cycling - Bike frame company with a rider weight limit

I read ages ago that one of the leading frame builders has a weight limit of 90kg (198lbs), but I could never remember which.

Well, I finally stumbled upon it again....it's VINER
http://www.viner.it/english/index.htm

Viner have this weight restriction as a general guideline for use of all their road frames, and I say good on them!! Their Dedacciai U2 frame has a 75kg (165lb) limit!!

I can't see how their frames would be any weaker than most of the other leading manufactures.

You can't tell me there's nothing wrong with a 250lb guy riding an 1100g Columbus Airplane frame.

So, I dare the other companies to have the guts to place weight restrictions on their light road frames. :)

i guess magnus backstedt will have to re-think his paris-roubaix victory and the bike which was not strong enough for him.

or not.

bikes are tough things, and the triangle is one helluva stable/strong geometry to bear loads. "weight restrictions" are for legal reasons, not scientific ones. campy components, btw, have long "recommended" weights below 180 lbs or so.

You mean for guys that weigh 210 or 220 shouldn't use Campy? I don't understand how a persons weight on the frame of the bike would effect the components. I'm not doubting you, just think it sounds weird. The only way I can see it causing a problem would be if you were out of the saddle shifting.

I think DeRosa used to put an 80kg weight limit on their Aluminum frames, but then stopped. I read this was more for marketing reasons than because their frames got stronger. Apparently even people who are under the wieght limit doen't like the thought that the frame they are ridding has a limit.

You find limits on Ti parts and carbon parts. So why not on frames? They have to be built to some spec.

Weight limit? How about height minimum? :D

no no, on the contrary, i'm saying that not only do frames have weight limits outlined by the manufacturer, but so do components. and i'm saying it's all hooey. magnus backstedt is a heavy guy and won the paris-roubaix.. (i was being semi-sarcastic in my above post). and i'm 220 lbs and use campy just fine.

Oh ok..lol just trying to get a clear up. thanks

I think some Deda tubing has weight limits too.
Mountain bike suspension forks as well.

G'day,

in the fine print you will find many manufacturers have 'weight restrictions', on components...obviously there is a 'built in' buffer over & above the limit they have stated. I mean if you are riding a wheel that recommends no more than 90Kg, if you weigh 90.1kg, will that make any difference?.....'cause not!. By the same token, If you way 120kg & have 'broken' your '90kg' wheels....get some skinny bastard to take 'em to the LBS for 'warranty discussions'!....LOL...these weight restrictions are like the 'Lawyer tabs' on any fork coming out of, or going into the states......they are a safe guard against the manufacturers getting sued.......You know the story....guy weighs 450lbs & breaks his neck, when wheels weighing 1.2kgs collapse under him....bike company says, 'not our fault...we told the fat bastard not to ride it"....treat the weight restrictions as a guide only,

cheers,

many manufacturers do that, put ridiculous limits on the use of the product as part of the CYA strategy.
