My Wheels Manufacturing PF30 BB is dying a death and I’m pretty sure it is the bearings rather than anything more technical. According to the box, it is the Angular Bearing model of the BB – I can’t find any shop open that is aware of these BBs (I haven’t tried many!) but, what makes angular bearings angular?
According to the info on Madison UK’s website, the BB system uses –
6806 30 mm ID bearings are installed to machined Delrin cups adaptable for both 68 mm and 73 mm shell widths
Now that looks/sounds pretty standard to me, so would standard bearings fit? Is the angular bit the bit inside the actual bearing itself? Therefore any bearing that meets that size (6806 with an internal diameter of 30mm) would fit?
Looking on the Enduro website, they have an exploded diagram of their angular contact bearings and the outer surface of the bearing appears to be flat.
Needing some pointers so I can order up the replacement bits and get the BB back on the silk smooth road!
Also, has anyone who runs Hope Mono M4 brakes used Superstar component pads? I’m using the organic pads – stop me fine but they appear to be a fraction shorter than other pads as they rattle when the bike is moving…just thought I’d ask that as well in case it is just me.
