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.

Ice Technologies: The fade, which can occur to disc brake rotor and pad when braking on a long downhill ride has a negative impact on the braking performance. Shimano has adopted Ice Technologies disc brake rotor's and Ice Technologies pad's to realise the cooling technology for consistent performance. The clad disc brake rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminium and stainless steel, provides better radiation performance achieving from 400˚C to 300˚C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the clad disc brake rotor blade and the radiator fin provide long pad life, less noise, less fade and lightweight. One Way Bleeding: One Way Bleeding was developed for quick and easy prevention of air in our hydraulic system. We have streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.Click HERE to check out the Shimano Brake Reference Guides.A 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.
