Minoura Japan – Left Side Coupling Bolt

An optional coupling bolt for the fixed nut type rear wheel bikes. Applicable with V-series and new M-series frame only.

The standard left side coupling bolt is designed to fit the included quick release skewer only.
If you use the trainer with the fixed nut type bike, the coupling hole size is too large to the skewer head and we cannot guarantee the stability while training.
In addition, the standard coupling's length is designed to fit 125mm or wider rear wheel hubs, so it is impossible to hold the bikes with narrow hub width such as old 7-speed or track bikes because of the too short bolt length.

This optional coupling bolt solves these problems with its longer size and larger hole size.
Please be sure this bolt will not fit any quick release skewer head.
