Crankset
Shimano Ultegra R8100
The 12-speed Ultegra Hollowtech II crankset, a little heavier than Dura-Ace at a much lower price. Unlike Dura-Ace it is only offered in compact and semi-compact ring pairings, so riders wanting a 54T big ring on a tri bike need to look elsewhere.
Fitted to 82 builds across 80 bikes in the database.
