Why We Like The Ultegra FC-R8100 Crankset

12-speeds of range and a host of hyperglide technologies comes standard on the Shimano Ultegra FC-R8100 Crankset. This new offering from Shimano continues the sleek look and gets us cruising down old loops and new roads. The 12-speeds of range is new to Shimano lineup and gets a quality crank to match. The 24mm shell is standard on Shimano and doesn't change with the new generation, allowing for easy swaps from our 11-speed groups.
