This is the MRP Mega G3 Chainguide with Integral Bashguard – ISCG. MRP pioneered the concept of chain retention almost 15 years ago with their System 1 and years later revolutionized the field again with the G2. Never content to rest on their past achievements, MRP are excited to present the G3 – which promises unprecedented performance, durability, and usability for demanding gravity and trail riders. The G3 features MRP’s patented integrated skid, which protects critical drivetrain components like the crank and chainring from damage and glides over rocks and obstacles. New to the G3, the skid and lower guide are combined into one solid structure. By unifying these two parts, they’ve made the portion of the guide most exposed to damage able to take hit after hit. The skid and lower guide also feature our new attachment system, the Swing set. The Swing set system features a pivot at the forward skid mount that allows the skid to swing down for super easy crank and chainring installation. This feature along with the retained and pivoting upper guide allow for quick and frustration-free installation – achievable with just one single 4mm HEX wrench.
