Bateleur1 Posted February 28, 2018 Posted February 28, 2018 Does Carbon frames have a life expectence? Not talking about crashing with the bike. But would there be a point where one should contemplate replacing the frame? Not sure if this question should be posted on a Friday
Grease_Monkey Posted February 28, 2018 Posted February 28, 2018 Well some companies give a lifetime warranty on their frames, so unless there is any crash damage I don't see why you should be looking at replacing the frame after X years. You are going to want to get a new frame due to texh advancements/new standards far before the frame's life expectancy has been reached...
Pure Savage Posted February 28, 2018 Posted February 28, 2018 There is no life expectancy, unlike ALU.

Bateleur1 Posted February 28, 2018 Author Posted February 28, 2018 There is no life expectancy, unlike ALU. That is what I would think as well. Alu does not last long. I am just wondering about possible stress fractures. The only reason I can think this happens is either in a crash or when clamping the frame on a bike stand or something but other than that there should be no risk.
Underachiever Posted February 28, 2018 Posted February 28, 2018 Anecdotal evidence. Bought a Giant TCR in 2004, first my only bike, then later a training bike. Covered 63 000 km (say ca. 2000 hrs) to date, and still regularly use it in smaller races. Good as gold.

But would there be a point where one should contemplate replacing the frame? Not sure if this question should be posted on a Friday I don't think there is any reasonable life limit, chances are the components on it will become obsolete before the frame needs to be retired. Like Underachiever, I've had one carbon framed road bike since 2004 and it has done many hours on the road AND (heaven forbid) on an IDT. Basically summer outdoors and winter on the IDT (all in Switz, so fairly lengthy winters). What might be interesting though.... is the effect of extensive sunlight on carbon frames without paint or clear coat protecting the fibres?
solty Posted February 28, 2018 Posted February 28, 2018 It's a composite material of the actual carbon fibres, that give the strength, and a resin binder. Deterioration would come from damage to the fibre-resin bond (like crash impact shattering the resin or causing delamination) or deterioration of one of the 2 components of the composite. Deterioration of the resin is more likely, by say high temperature. The carbon fibres don't degrade easily. Share genes with diamonds. Your grandkids will still be riding your Carbon bike. There was an interesting article about eco friendliness of CF versus Alu on Pinkbike I think.
Frosty Posted February 28, 2018 Posted February 28, 2018 My 2007 Schwinn is still serving me well, 3 crashes later. A few minor upgrade/downgrades, here and there, to the components, but the frame is still good for as long as I look after it. All seasons, indoors and out - except for races, which use my Ritchey Logic. Sent from my iPhone using Tapatalk
American Flyers Posted March 1, 2018 Posted March 1, 2018 Most companies used to say, they give a lifetime warranty on their frames, but not anymore.Now they give you 5 years warranty, we must check small fine print....
carrera4s Posted March 1, 2018 Posted March 1, 2018 I have a U16 friend that rides a 2008 Felt F1 - review here: http://www.bikeradar.com/gear/category/bikes/road/product/review-felt-f1-07-16470/ His FTP is around 290 W but when he starts sprinting flat-out, the frame flexes so much that his rear wheel rubs against the chainstays. There are two grooves in the frame already. American Classic carbon wheels. 23 mm tubby.
Duane_Bosch Posted March 1, 2018 Posted March 1, 2018 Does Carbon frames have a life expectence? Absolutely they do. When you are bored with it you should retire it and get a new one.

American Classic carbon wheels. 23 mm tubby.For such a small rear triangle, plus this fact that it's very difficult to find a carbon frame that flexes, even when "old", methinks the flex lies with the wheel/tyre combo.
