1.5mm wedge for cylinder base. High quality aluminum machined. Made in Europe for RRD. Original shape to be adaptable to all cylinders of MOTOBECANE AV7. Allows the increase of diagrams for the installation of long stroke crankshafts (in combination of base seals).
Also allows to correct the defect of PARMAKIT cylinders which are delivered too low! Made in small series in quality materials, which explains the price a little high for this small room.
One of the best crankshaft on the market with top balancing, revised and corrected lubrication and of course with a top finish as usual at AIRSAL. Here is the direct competitor of the famous DOPPLER Endurance crankshaft.
