The brake levers with finger grooves (PN32722072252) currently available in the market, do not fit in the throttle housing of the R26, R27, R50 – R69S models.
The hole for the lever screw is of few thenth of a millimeter off it’s original position: the lever gets blocked and cannot be “opened”.
New brake levers that do not have this problem are only expected to become available by the end of 2017.
Till then, the solution is to mill off +- 0.3 mm from the edges on both sides. After polishing, no traces of milling are visible anymore.
This is what we do with the brake levers offered in or webshop.
This way the brake lever can pivot freely in the throttle housing
