OChain EBike Active Spider - Bosch Compatible - 52mm Chainline - Nero netsuite-webdata-created the Youth Mainframe Helmet willGet that super smooth chainless feeling and minimise the negative effects of chain tension on your E Bikes rear suspension with the OChain E MTB Active Spider. Inspired by some incredible chainless runs on the DH World Cup circuit (Neko Mullaly Hafjell 2014, and Aaron's Gwinning run Leogang 2015). The designers pondered the question of whether the lack of a chain was a factor in the way their bikes performed during those runs. OChain was the result.
