dpardo Power Curved Crankset56/42－Super7-BF-2

dpardo Power Curved Crankset Torque Output increasing 33_ between 0_60 degrees test by SGS Using Big Foot 56T gear, Pedal fast and easy to reach 40km/h Bike up Taiwan Great Snow Mountain directly! Power Curved Crank Features： 1.Torque output increasing 33_ between 0_60 degrees test by SGS. 2.Power curved crank with Silent gears(56/42T)is more efficient combination. It could easily drive 56T gear (as easy as 50T) and get fast speed. 3.Precise manufacturing process：Crank’s deformation tolerance is within 0.1mm. 4.Repeating finishing process to make surface delicate and smooth. Hard anodized curved crank, its thickness is 50μand hardness is 500hv 5.Embedding a steel sleeve into crank arm to make crank more durable and extend its life! Silent Chainrings Features： 1.Quite and low noise , easy to shift and move quickly between gear and gear. Close contact with chain makes power transmission fast！ 2.Compatible with almost all derailleurs to shift easily and move up and down gears quickly！ 3.Silent chainrings’ teeth shape of our proprietary－close contact with chain makes power transmission fast and low noise － good abrasion resistance so more durable！ 4.High quality imported 7075 aluminum plate and 100_ CNC machined chainings’deformation is within 0.1mm and not easy off the chain！
