Cool, I need to read read and reread it, then bring it to someone and ask. Truthfully, I live really close to Orange20 (if you don't knwo them look them up). Groovy hipster very professional bike shop. Might just bring to them, tell them what was suggested. It's prob a 10 min. job for a professional OR I also live close to the Bike Kitchen. Do it yourself co-op with folks there to help. BUT...your info at least will allow me to ask for help without looking like a total idiot. You know I'm THAT cyclist. The one with the funky step through, a couple stickers, bell, computer, lights...and never ride
