Product description
This bottom bracket is when you have a PF30, or 386EVO shell frame and want to install a 30mm crankset into the frame. All have a 46mm inner diameter, though the widths vary from 72mm to 86mm. Compatible cranks have a 30mm diameter spindle.
PF4630 Bottom Bracket MTB features nearly zero loss of power 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 laid onto the races, making them exceptionally hard and smooth, resulting in longer life and lower drag than other options. The bearings come installed in matching cups.
In the box:
- 2 cups with bearings installed
- Assorted spacers
- 2 dust covers
- O-ring for precise preload setup
- Spacer tube
- Long Life Grease
- Decal
