Excuse my curiosity, but what's a Delrin Angle? I'm assuming it's the slanted piece to go over the bump, but then again, you never know. Well, you probably know, but I don't.

Thanks!

The angled part of the frame appears to be covered by Delrin, which is a rather slick type of plastic. The other option that I can think of, HDPE, is also somewhat slick, but Delrin is slicker. In block form, Delrin has been used as a chain tensioner in the past--stick the block in so the chain is slightly too tight and let it find its own tension by digging into the block.

Thanks! I appreciate it!

Delrin is a material developed by DuPont and is widely used by teams. That piece could also be HDPE or UHMW.
