Experience shows that the original spacing sleeves easily slip out of their place in the rims when removing the back wheel. If the wheel is replaced e.g. after changing tyres, the series sleeves become twisted so that putting them back is often very "fiddly" and tests your patience. The wheel spacing sleeves we have developed are used in place of the series standard sleeves and form-fitted in the radial shaft seal of the rim and chain wheel mount. Owing to their design, these then lock in place and the risk of their falling out during a tyre change is reliably prevented. The spacing sleeves are also generously, flat chamfered so that insertion and assembly of the wheel is noticeably easier and faster. Originally developed for racing, they've proven very useful for significantly reducing waiting times in the box when the wheel needs to be removed. We regularly use the tried and tested »TRACKDAY« sleeves on our racing bikes during racing. We manufacture the wheel spacing sleeves from high-quality aluminium and anodise them in blue. With Wunderlich MOTORSPORT logo.
