Crankset
Shimano 105 R7100
The 12-speed 105 crankset launched alongside 105 Di2, using two-piece bonded Hollowtech II arms. It is the heaviest of Shimano's 12-speed road cranks but costs a fraction of Dura-Ace, and it's common on entry-level tri bikes, often with a left-arm power meter added.
Fitted to 63 builds across 44 bikes in the database.
