Do you just use F4R Bearings? are they >5mm thicker (1mm total either side)
Anyone using them ?

They're the same dimensions, the only fitment difference is F4R rods dont have a slot for an alignment tab
On the Wossner website i state the crank OD is 1mm different...
PEC rods sorry it states 51.6 for the F4R and 50.6mm for the F7ROriginally Posted by Evogone
