Description
- CRANKSET FIT: SHIMANO and other JIS 2.0 Degree Square Taper type
- SUPER SMOOTH PREMIUM BEARINGS: Premium ABEC 5 standard, Grade 5 Chromium Steel Balls, and polished 52100 High Carbon Chromium alloy races sealed with X-SEALS. Extremely close tolerances for I.D. and O.D., roundness of ball, trueness of the races and micro surface finishes of balls and races.
- SUPER LIGHTWEIGHT & STIFF HOLLOW TITANIUM SHAFT: Strong and stiff CNC machined hollow titanium shaft for extra weight savings. JIS 2.0 degree square taper shaft
- SUPER LOW FRICTION X-SEALS: Patented technology uses Low Friction Dual Lip Seals housed in the Premium bearings and CNC machined alloy cups. This allows the seals to fit very precisely and allow for less contact between the rotating parts in order to reduce energy-wasting friction. In addition, the seals provide better protection for the bearings since there is less space for the elements to get past the seals.
- SUPER LIGHTWEIGHT THREADED CUPS: CNC machined durable forged aluminum alloy cups with X-SEALS.
