The 2013 North American Handmade Bicycle Show featured a lot of innovative new bike designs. One of the bigger trends for the last few years has been the various implementations of Gates Carbon Belt Drive systems. Paragon Machine Works, known for their frame building parts, actually built their own bike for the show implementing their new Toggle Drop quick release belt drive tensioning system.
The Toggle Drop is a patent pending dropout they will be offering in the future that fits a 12mm x 142mm axle. Paragon says the dropout “allows for rapid removal and re-installation of the rear wheel into the dropouts, while maintaining your belt position.” The titanium 29er they built actually won Best Belted Mountain Bike from Gates Carbon Drive. The innovation didn’t stop at just the dropout, the bike also featured Pinion’s P1.18 18 speed internal gearbox with a 600% range.
