Hi All

When we had the gear stripping problem on the MTX4R we made sure of the mesh, 2 speed shoe being set tightly etc.... everything that has been mentioned but what fixed it for us was......


"Take the balls/roller out of the two speed, remove the 3mm grub screw and then drill the 2 speed shoes out to take a 4mm grub screw. Screw the 4mm grub screw directly down onto the cam". Then set the 2 speed closely to the holder to have a very smooth change, by doing this it made the gear change very consistant and smooth.

Our stripping problem went away, I appreciate the 5 has flex but give this a go it may work.

Good Luck (Convert now to Xray!!!)
