precision Facing

[Jongozi]

Hi guys.

I need technical help.

I have an ORBEA ZONAL (not sure if it is the COLUMBUS) frame which was originally fitted with a campagnolo group set. I bought a secondhand SRAM Rival set. I was informed by my local bike fundi that I will have to have the chamber for my BB resized. This is called “precision Facing” as the old frame and new BB do not pair precisely and this will lead to bearings being worn-out every couple of months. Where can I have this process done and what is the cost?

Then, the SRAM cassette does not fit on the Campag Scirocco rim. What type of rim must I buy to fit the SRAM cassette besides a SRAM rim?

Your LBS should have a BB facing tool, its actually quite simple.

 

You should be able to get a shimano freebody for your scirocco wheels, just ask at your LBS.
