NEW 165mm Shimano Ultegra FC-8100 Crankset 12-speed Road 165 Short/Dura Ace/105/Di2

EXTREMELY hard to get shorter 165mm crankset. Since Tadej has shown the merits of 165mm crankset to the world.

Made in Japan. New improved design which prevents the failed bonding issue that plagued previous Ultegra (6800 & R8000) and Dura-Ace (9000) cranks. This is brand new with full warranty. Any problems just let me know and I’ll deal with the warranty as I’m the original purchaser and have proof of purchase. I think it’s 2 years. This was bought late April 2026.

165’s are proven to give advantages in speed, power, cadence, aerodynamics, fatigue prevention, efficiency, comfort and injury prevention.

An absolute revelation for riders with poor flexibility and/or hip impingement.

This set is brand new in original box, never fitted.

Works with all Shimano 12-speed groups and fine with 11-speed too.

Mid Compact 36/52 ratios which is the most versatile crank for high speed road/race/fast group ride use as well as climbs and general flat riding. Pair with an 11-34 or 11-36 cassette for rides with steep climbing, but for general flat/mixed use a close ratio 11-28 is pure joy.

The crank has Shimanos new standard 4-bolt eccentric BCD so you can fit compact 50/34 rings too.
