We recently added Q Ball and Quiring frames to the list of fun stuff that we stock. The Q Ball pictured is a USA made steel 29er mountain bike.
It has a horizontal dropout, derailleur hanger, and sliding disc mount which means it can be built as a multi speed or single speed without adapters. A large Q Ball frame tips the scale at 5.42 lbs. www.qballbikes.com
You guys keep getting such cool stuff.>>A Q-Ball would be a nice alliterative companion to my Quickbeam.
Quiring–nice! Been back and forth via email on a custom steel SS with the man. Great stuff, just ask Jason, ha. >>Nice work.
