MRP G2 Guide Test
While not the first or only people to fabricate a chain retention device, MRP is arguably the first to do it properly. When the System 1 was first produced in 1996 it set a precedent for chain guides. When a lot of other people were installing spring loaded derailleur tensioners or chain stay mounted rollers, MRP began to produce the simplest solution to what turned out to be a not so simple problem. As time passed, bike designs evolved, and so did the rider's skill. Their line of guides also expanded to include the System 2, the many options of the System 3, and the latest design, the MRP G2.
I've spent the last few months trying to do my worst to the G2. Want to know how it worked?
