Set your axle play once and forget it!
Use the axle stopper on the side opposite to the spur gear so that your axle fit and play is not affected when you change wheels. Time saving during handout wheel changes at competitions. Excellent during an Enduro event, particularly for wheel changes during the night sections.
For all 3mm axles. Precision machined from billet, aircraft grade aluminum and cross drilled for additional lightness. Electric blue anodize.
Price is for a package of two (2) stoppers with set screws.
