Center cap PF4630

This bottom bracket is for when you have a PF30 or 386EVO frame shell and want to install a 30mm crank on the frame. All of them have a 46mm inner diameter, though widths vary from 72mm to 86mm. Compatible cranks have a 30mm diameter spindle. The PF4630 MTB bottom bracket features almost no power loss due to friction, thanks to the bearings. Our coated bearings have super-round, super-smooth CeramicSpeed balls rolling on hardened steel races with a metallic coating applied to the races, making them exceptionally hard and smooth, resulting in a longer lifespan and lower resistance than other options. The bearings come installed in matching cups.
