Details

The 45T X-Cog upgrade increases the stock Shimano 11-speed 11-40 cassette range by 12.5%. The 45T provides more total cassette range, it’s not just an easier granny gear. Adding the OneUp 45T X-Cog lets you increase your 1x11 front chainring from a 30T to 34T without losing any low range. Eliminate dropped chains forever with our true narrow-wide chainring design. This cog tunes the cassette progression into two distinct zones optimized for climbing and descending.

  • Climbing: (21-45T) 13-15% cassette progression. Smaller jumps to maintain an optimum even climbing cadence.
  • Descending:  (11-18T) 15-20% cassette progression. Larger jumps to reduce double tap shifting and provide faster burst acceleration when mainly pumping not spinning down trails.

  • 18T sprocket provides more even cassette progression for smoother cadence and improved shifting
