Forgoing the CF sucks and steel/ti rule debate that will rage here until some other material pops up that the steel/ti contingent can focus their disdain on. I will say that I clearly intend on buying a new frame set every 2-3 years. Next seasons bike will most likely be a CAAD9, possibly a SystemSix I haven't quite decided. As for longevity, my Al CAAD8 frame may not last as long as a steel or ti bike. However the equivalent quality steel or ti frame would be 2-3 times as expensive so it's statistically a wash.

The real heat shield on the hot-parts of the shuttle is designed to take in excess of 2300° F (1260° C).... hence the carbon-reinforced-carbon-ceramic-tiles... |

Saw a coffee mug on clearance at Kohls, had "Rocket Scientist" printed on the side. Need to get your mechanic one.

And the truth is the shuttles with all these super modern composite materials stay on the ground, or blow up if the tiles are not changed regularly. What do the carbon frame manufacturers tell us about their material? This: Carbon frames, made of the same material used in space shuttle parts |

So according to this shop mentioned in the OP...my 2001 CF Trek 5500 is about to self destruct on me. yea....right.:rolleyes:
The LBS owner the OP mentioned is totally and utterly full of *hit!! I'd find a new LBS to deal with. |

Jump on the curb and back several times, being on the bike, of course. |

What do the carbon frame manufacturers tell us about their material? This: Carbon frames, made of the same material used in space shuttle parts We just need to get two things straight: 1-Carbon Fiber Reinforced laminates are used on bicycles AND parts of the space shuttle. 2-The shuttle HEAT SHIELD is made of Carbon-Carbon Ceramic Tiles that DOES NOT CARRY SIGNIFICANT STRUCTURAL LOADS ...we're not even talking about a remotely similar material here...just because there's the word "carbon" in it... Hey, I'm carbon based but I won't make a great bicycle frame NOR shuttle heat shield... ;) |

Nobody said anything about OCLV. We're talking CF here. And the 2300 was mainly CF. 20 years ago. Trek tried, in 88 to make a seven tube frame, any many (if not most) came back to them as they cracked. It really was not until they developed the OCLV process that they really figured out how to do this right. I see 3-4 of those old 2300's come in every year for service. Still out there being ridden. |
CF handlebars
I was looking for a new handle bar and was thinking about spending a bit extra for a CF upgrade. The Ritchey site has a technical article that states that all light weight parts have a limited lifespan and recommends replacing CF bars every 3 years even if they have not been in an accident.
Am I going to spend $300 for a new CF handle bar every 3 years when I have an aluminum one I have had for 25 years that is as good as the day I bought it? Having said that, I have a Giant TCR C3 and I intend on keeping the frame for at least a decade. |

I enjoyed seeing his bike, and he said he still loves it. Here's a head shot of it.... http://img97.imageshack.us/img97/3954/dsc02015zm9.jpg Another shot in the group.... http://img430.imageshack.us/img430/144/dsc02004wi9.jpg It's the pleasantly visual one....you can't miss it... |
