MRP AMg (V2) chain guide review
Today’s chain-retaining chainrings and clutch rear derailleurs do a great job of keeping your chain on, but sometimes it pays to be prepared for the unexpected, and this is where the AMg comes in. This top-only enduro/trail guide is designed to give additional insurance on rough terrain.
The V2 guide is 20g lighter (120g) than its predecessor and has an integrated skid plate to prevent damage to the transmission from rock and stump strikes. The guide itself is now smaller and has a softer plastic inner to reduce noise.
MRP offer versions for ISCG and ISCG-05 mounts, and 32-38t (tested) and 26-32t chainrings. Installation takes minutes and only requires a 4mm Allen key.
In the hills, the V2 was silent from the offset and the extra protection provided by the lower skid plate was a confidence booster when negotiating nasty boulder fields or tricky off-piste sections. The lack of a lower guide or roller never caused any issues with chain loss on our clutch mech equipped test bike, and things ran smoothly throughout testing.
