Shimano’s new Dura-Ace 9000 were given numerous press for numerous reasons: the jump to eleven-speed, the pretty design, the brand new lever ergonomics, however most likely greater than anything else for the crankset and its all-new, 4-arm spider. It is nice to take a look at, however what is so nice a few proprietary (and heretofore secret) BCD? No wish to buy a compact crankset. With the Dura-Ace 9000 crankset, you’ll run anything else from a 50-34 combo to a fifty five-forty two simply by swapping chainrings and moving your derailleur (most likely swapping chains, too). Effectively, this implies your motorcycle generally is a TT ride one weekend, and a hill climb champ the following. It is a little more work, however if you are a privateer racer, or an enthusiast on the cheap, it makes numerous sense.
