I wasn't sure if I would like it but it feels really good. The weight is comparable to the Shimano crank I replaced. The anodizing is a good color of red - better than many cheaper red components that tend to be a bit pink or magenta. The BB is nice and smooth as well. The 170mm crank length feels better than the 175 I replaced. I may even go to 165 on my next bike. I would highly recommend for a budget upgrade with good quality and weight. Review: A Hollowtech Type Crank Set for Mountain Bicycle - This is a great quality retrofit crank set. Servicing the drivetrain has never been easier with this type of single speed front sprocket. The sprocket can be mounted on the inner or outer mounting surfaces. I have discovered the inner mount location provides for better alignment with the rear sprocket assembly. The price is good and the crank set works good. ## Features - Chainring: snail single speed narrow wide teeth chainring, 30T/32T/34/36/38T round/oval chainring,thickness is 4mm (1.9mm narrow, 3.7mm wide) - Crank:104 BCD mountain bike crankset. length of crank arm is170mm, crank related holes distance is 74mm, crank weight: 550g, fit 7-12S chains and single/double/triple speed chainring - Material: Crank and chainring made of aluminum alloy, light weight, high axial strength and compatibility - Bottom Bracket: Size is 41*24*24 mm can fit bike bottom 68-73mm,ideal for Shimano, FSA compatible.
