Details:
Shimano took this opportunity to simultaneously introduce an Ultegra branded 10-speed compact crankset (50-34T). It will be available in two colour options: standard silver and “Ice Grey”.

The “Ice Grey” double crankset (52-39T and 53-39T) is 35 grams lighter than the current version. Also a triple crankset will be available with a chainring combination of 52-39-30 teeth.
All Ultegra cranksets have been developed with Shimano’s proven HOLLOWTECH II technology that increases rigidity while saving weight. They also feature Shimano HYPERDRIVE technology with shift ramps and special designed chainrings for an unmatched front shifting performance. Crankarm length choices will be 165, 170, 172.5 and 175mm.

The “Ice Grey” Dual Control Levers (-43g), rear derailleur (-9g) and brake calipers (-10g) are also more lightweight than the standard Ultegra components while performance and durability stay the same.
