MRP 1X Chain Guide - Seat Tube Mounted

1X SERIES seat tube mounted Chain Device - MTB version with vertical adjustment to allow smaller chainrings down to 32T .

Developed with World Cup powerhouse Adam Craig, the 1X (pronounced one-by) is purpose-built for cross country riding with a 1x9 drive train.

If you are running 1x9 and don’t need a bash guard, this is the ticket. No more homemade contraptions needed! Fits most seat tube sizes 28.6, 31.8 & 34.9mm (with supplied rubber shims).

MTB chainline = 49-51mm for middle chainring position on MTB Triple crank.

MRP also gave the MTB version significantly more vertical adjustment, due to the small chainrings that will be used (32T is common) and the large quantity of carbon bikes with flared seat tubes at the BB junction.

  •  32-40T
  • Weight :  MTB 74g
  • Black or White Upper Guide.
  • Chainline adjustment.
  • Seat Tube Mount - Fits seat tube sizes 28.6, 31.8 & 34.9mm with supplied rubber shims.
