For every frame we ship out here at Just Pedal we can (when necessary):
- ream and face head tube and bottom bracket tube
- face the crown race of the fork
- Install headset and/or bottom bracket
Why would you Ream or face your frame and fork?
When using 2 seperate cups for headset (always) or bottom bracket (for all non-square taper bottom brackets) it is important these 2 cups are as parallel and in line as possible. Most tubes are straight (and if not, there is nothing a normal mechanic can do about it), so the cups will be in line, but not all tubes are cut straight, and also paint may cause this non-parallelism. By facing both ends of the tube you can ensure the cups are seated in the frame as parallel as possible. This will cause less wear of and play in the bearings.
