Your Budget Shimano Replacement Introducing the new Power2Max edition crank by Rotor. This is a direct replacement for your shimano crankset with a 24mm spindle that fits all compatible shimano BB's. This is a more budget version of the Rotor Aldhu crank. The aluminum crankset is forged and hollow-bored and weighs only 542g. Its 24mm steel axle allows it to replace all current Shimano-cranksets without using any special tools. Due to customer demand the set was developed for the Shimano Hollowtech II buttom bracket standard and combines superior stiffness with an excellent price-performance ratio. If you want to continue using your Shimano Dura Ace, Ultegra or 105 4-arm chainrings you can choose our 110 4-S version. This setup allows you to keep the optimal shifting performance. The 110 4-SL version also saves 30g compared to the regular 110 4-S version.
