Got the Tektros in the mail today and slapped them on the fork with a spare wheel that's about the width of the rim I'll be building when the rest of the parts come in. The shoes hit the fork, but there's enough room for the rim and even the tire to clear (but just barely). Again, I'm not confident with the nuances of adjusting these yet, and I'm not at the point in the build where I can actually fit everything up and test it (still have to press in a headset, among several other things). If someone wants to take a look at the pictures below and let me know if everything looks like it'll work together, I'd really appreciate it! If some other pictures or information would be helpful, just let me know and I'll be happy to provide it.

Any insight should be helpful! Thanks for all your help so far guys.
