The Bish Bash Bosh Rear Mudguard Adaptor Bolt kit is simple to use. Just thread them into the drop outs by hand, wind them out a turn and half and then cinch up the lock nut with a small spanner- 2nm is tight enough so go easy!
Simply line up the bottom of your mudguard mound with the eye in the eye-bolt and lock them together with the M5 bolt that came with your mudguards. Job done, go out and ride.
NB: These are lightweight aloy bolts and not suitable for mounting panniers.
