Hi - I'm new to the tandem forum, having just bought a Trek T900. The primary riders on will be me and my young daughter. I'm concerned about her foot getting caught between the timing chain and chainring. It's already happened a couple of times at low speed riding around the block, but can imagine this could be grisly on a "real" ride. Is this a common problem and the risk go away once we both get used to riding the bike? I've thought about putting a mountain bike bash guard on the outside of the stoker chaining - any thoughts on whether this would help?
