What is the most durable Shimano group?(5 posts)

Well, Campy would be interesting too, but, the basic question is, at what point does Shimano start sacrificing durability for the sake of weight savings?

I have heard that an Ultegra cassette with lost longer than a Dura-Ace one. Does this mean that a 105 will last longer than an Ultegra one? Not necessarily. That said, there is probably no way to tell on paper which will last longer.

In addition to which component group is the most durable... for which components should durability be a consideration? Obviously cassette and chainrings, but STI levers, almost certainly not (dura ace is lightest and at least as durable, I think). Any others to think about?

I have always suspected that Ultegra and Chorus are most likely the most durable groups between the 2 companies because of the fact they are high up enough in the group to get the superior build quality and materials but not to the point of weight savings craziness that jeopardizes their durability like Dura Ace. There are all kinds of real world stories about the poor braking of D/A and Record vs Ultegra and Chorus because ofvweight savings in the brake calipers, how about the durability of the D/A BB?? How about comparing the durability and reliability of the Record carbon rear derailleur vs the Chorus rear derailleur. Ever felt the Record 10 carbon shift levers action side by side with the chorus 10 shifters - the records feel very plastic and flimsy even though they are carbon. Weight savings in any component eventually reaches a point where durability issues start to come in, this includes frames, forks, you name it. Why do you think so many pros frames and components are essentially treated as disposable??

You forgot the Soft Ti cogs on the cassette. I have Record 10 Triple with 2 Chorus downgrades. The cassette, and the seatpost. The Chorus seatpost is Ti vs. the CF record seatpost, and the all steel cogs are quieter and are much more durable.
Chorus! ;-) nmSpunout
