Double Crankset
is double Crankset Shimano 105 upgrade from a fractory triple crank?
i ride a 03 Specialized Allez information only on the crank on the site is 52x42x30 Specialized Comp five arm 105 is a 39×53
What is the factory crank set? edit-MR is where possibly an update, but more a change of a triple-double, there will be some savings and duplication of arts wieght a little less. the 105 stuff is pretty good, havent I had no real problem with the components of my 105 though I have a 105 crank. IMO, seems a sort of unecesary update unless your current setting is I seriously broken or missing might sugesst other improvements such as a more comfortable seat, pedals better or more clear, nice tires, etc. failures better
Last Double Crank!?!?

SRAM Red Shift/Brake Lever Set
The NASCAR-stylized graphics package screams at you when you pull a new set of Red DoubleTap shift levers out of the box. It's a far cry from the sedate look of first-generation Force levers. There's plenty more going on, though, besides eye candy: Red levers weigh 280g, 25g less than Force. And arguably best of all, with Red you finally get the ability to micro-adjust the position of the front de... |
