MRP Announces 3 new versions of the popular 1.X Chainguide


GRAND JUNCTION, November 4, 2009: With the list of cross country championships piling up from the 2009 season, MRP is proud to announce 3 new versions of the ultra popular 1.X chainguide.

1.X MTB Clamp On: For those riders who have been excluded from the 1.X movement due to their press-in bottom brackets like BB-30 or cranks that aren’t compatible with the BB-mount version. The guide clamps right onto a conventional seat tube, just like a front derailleur.

1.X Cross Clamp On: By popular demand, the 1.X Cross is a seat tube mount guide that will be compatible with CX bikes running a Road Double crank for the optimum chainline. The guide clamps right onto a conventional seat tube, just like a front derailleur. Carl Decker rocked a prototype of this one at Cross Vegas 2009 in September.

1.X Direct Mount: This 1.X will bolt directly to the frame, utilizing the new Shimano Direct Mount for MTB front derailleurs. This will allow riders to use the 1.X on frames that have both BB-30 and un-conventional seat tube designs.

All 3 versions are adjustable for fine tuning the chainline.

Developed with input from some of the world’s most demanding riders including Adam Craig and Ross Schnell, the 1.X was designed to allow cross-country riders to take advantage of the huge weight savings (a full pound or more) and simplicity of a single front chain ring without having to worry about their chain falling off.

MRP is a small company based in Grand Junction, Colorado. With countless World Cup and World Championship victories, MRP has been the choice of champions since 1996. MRP’s patented technologies put them at the top as the leader in smooth, silent, reliable chain retention.
