The rigidity of the crankset ensures pedalling efficiency while its low weight, a key element of the crankset, aids in cycling longer distances. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank. For most frames, Hollowtech II with its 24mm axle can set the bearing position outside of the frame to provide better weight distribution and more stability. Hollowtech II bottom brackets also have high-precision seals to increase durability, maintaining excellent rotating performance for long periodsA 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
