MRP's 1x iO is the SRAM Transmission-specific version of their 1x carbon chainguide, designed to work alongside a SRAM Transmission crank's own integrated bashguard rather than against it.

Highlights

  • Carbon (SLR) construction
  • Fits 28–38T chainrings
  • ISCG-05 mount
  • iO design integrates with SRAM Transmission cranks that carry a bashguard
  • Works with all SRAM Transmission bashguard sizes

Built for SRAM Transmission

SRAM's Transmission cranks ship with an integrated bashguard, which can conflict with a standard chainguide's backplate. The iO version is shaped to integrate with that bashguard instead, across all SRAM Transmission bashguard sizes, while keeping the same internal shaping for wide-range cassettes and chainlines as the standard 1x.

Compatibility & fit

Mounts to ISCG-05 tabs and suits 28–38T single chainrings on a SRAM Transmission crankset. Our workshop can fit this guide as part of a drivetrain service.

MRP backs this chainguide against defects in materials and workmanship for 1 year (2 years within the EU) from the original purchase date, covering the original purchaser only; normal wear items such as bashguards, skids and fasteners aren't included. For warranty support, return the product to Tune Cycles and we'll manage the claim with Link Sports, MRP's Australian distributor.
