Boo is famous for its Bamboo rigs, and Cyclocross Magazine was lucky enough to test and review pro racer Tyler Wren’s race steed for Issue 11. That bike’s smooth ride led to a very positive review, and we caught up with Troy Evans of Boo to see what the company had at this year’s show.
The singlespeed Boo with a carbon belt drive was not only light weight – weighing about 16 pounds even with modest wheels – but as Evans reported, it plows through inclement conditions. “At a recent muddy Bay Area race, there was no slowing down the drive system. I got a stick jammed in there, and [the belt drive] just snapped it in half.”
“I love my bike – a lot,” says Evans, “but I have to say the belt drive system is the coolest thing on here.”
Upgrades coming down the pike for Boo include a new all-carbon head tube and an all-carbon bottom bracket shell, which Evans estimates will save between 1/4 and 1/2 pound. A tapered head tube should be coming soon, and as Evans says, “We’re only making two bikes per week, by hand. So it’s pretty easy to customize builds for our customers.”Co-Motion: Belt Drive With Gears!
Eugene, Oregon, based Co-Motion’s primary business is building tandems, but the company makes plenty of single bikes as well. particularly eye-catching in this year’s line-up was a steel Americano frame with a Gates Carbon belt drive wrapped around a Rohloff hub.
The Rohloff is a high-performance internally geared hub that offers 14 evenly-spaced gears – that means no cross-chaining, and a tremendous range of 526% from easiest to hardest gear. Although the hub is a bit heavy for most ’crossers (it weighs about 1500g, but also gets rid of the need for two chainrings, a cassette and double shift levers), it’s awesome for a monstercross rig, touring, or for weatherproof, clean gear shifts with little maintenance required.
Add the Gates Carbon Belt Drive, and there’s even less required upkeep – no chain lube necessary, and tremendous durability in the house. While we don’t anticipate a slew to show up at the local races, it’s a cool concept, and an interesting approach to adding gears to the belt drive system. More photos below!
As an aside, look for cheaper versions of the Gates Carbon Drive to start showing mated with less expensive internally geared hubs on city bikes and commuters soon. There’s an application where a virtually maintenance-free setup is well worth a little extra heft.
