  1. Boone twist cranks made in Tennessee. He made awesome chainrings and cassettes. The rings worked really well. Everything first came out in 1996. Back when hopping up a bike was the thing. SRP, Paul, Kooka, all the companies we had back then….miss them!

  2. Just googling around it seems as though this Boone chap still makes cool titanium stuff but he’s switched to rings of another kind, the ones for your fingers. Some nice stuff.

  3. Boone twist cranks FTW!!! Originally made in Kennessaw, GA by Bruce Boone…along with his titanium twist bottom brackets, ti chainrings, and ti cassettes. He’s since moved on and sold the design rights and name to Brett Brown who’s currently producing both chanrings and cogs. Really nice looking stuff! I regret selling mine although they were merely bike art for me since I didn’t use them anymore. I do still have my key-ring chainring (its a mini of the larger outer ring) on my Subaru’s keychain!

  4. “Guess correctly”?

    This is an opportunity to showcase one’s education – usually

    Might have been some plagiarism, resulting in the more, “concise” posts, given the huge prize on offer…

    Keep up the challenges
