Additionally, is there a healthy range of movement for your bearing blocks when using belts? I understand chain stretches overtime and I heard pulley aren't known to stretch but do you leave extra room to make taking belts on and off easier?

Sorry for all of the questions, our team is small and young but we are trying to absorb as much as possible!

Thank you!

Brendan,

If your doing a WCD like 254/968 have done. Then broach the pulleys.

If you really wanna save some weight and lower part count just do center to center on belts. Don't even put in the bearing blocks. Sdp has a real nice calculator on their site to determine the correct c-c.
