Wunderlich - Trackday Back Wheel Spacer Sleeve - Brake Side Options:Blue After 10 minutes of useExperience 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.
