LOOK, MA, NO CABLES: SRAM HUB SHIFTS AUTOMATICALLY
Juboo, which means “bamboo step” in Chinese, is a new bamboo bike brand created by sustainable transport experts Rory McMullan of the UK and Carlos Pardos of Columbia, along with Chinese partner companies, Zhang Zhi and Shenzen Baoan.
work on projects throughout the world to promote bicycles in transport. We want Juboo to provide some funds, and generate publicity.”
One of SRAM’s newest creations on display at Taipei Cycle is the A2 (Automatix 2) internal hub for folding, city and children’s bikes. What makes it unusual is that the hub shifts automatically depending on the rider’s speed.
Originally from London, McMullan lived in Taiwan from 1996 to 2003 and provided marketing services for companies including Giant and Hi-bike.
“The new internal hub is very interesting for any type of bicycles since the speed at which the automatic gear change occurs is defined at the SRAM factory according to the specifications of the bicycle manufacturer,” said Marcus Schneider, a product manager.
bling, it is potentially useful for folding bikes, which often need a second gear.
Among other benefits, that means the SRAM-A2 is adaptable to any wheel size. The automatic mechanical system changes from a gear ratio of 1:1 to a faster 1:36, which corresponds to the SRAM e-Motion hub ratio between the second and third gear.
The A2 will be manufactured in SRAM’s Taiwan factory and available this summer. It can be specified for wheels with 20, 32 or 36 holes as well as for OLD of 120, 130 or 135mm.
The SRAM-A2 internal hub will be available with a steel shell in coaster (980gr), freewheel (910gr) and roller brake-compatible (910gr) versions as well as with an alloy shell for disc (870gr) brakes.
The SRAM-A2 is expected to be priced at a similar level as internal three-speed hubs. SRAM expects it will be used on many 2012 bicycles.
The Juboo city bike is made from black bamboo and white composite lugs.
“We are at the Taipei show to look for partners in the industry to join us,” said McMullan, who has returned to Taiwan to live.

“Bamboo is fast growing and sustainable,” said McMullan, who formerly worked for the UK’s Association of Commuter Transport. “The vision for Juboo is to be a brand for promoting cycling, a non-profit charity which will
“A bike made from bamboo is a metaphor for environmentally friendly transport,” he added. “Bamboo is the world’s fastest growing building material and is therefore its most renewable, while bicycles, of course, remain the most efficient form of transport ever invented.” The Juboo bike uses black bamboo from the slopes of Huang Shan Mountain in mainland China’s Anhui Province.
