I have a Rohloff speedhub and after 2 years hard use it is time to change the chain and sprockets. No probs with sprockets but the chain specs require a 8sp 1/2"x3/32" and no other. Can I find these particular specs mentioned in the usual on-line bike shops?....er no! The Rohloff specs sheet mentions that 1/2"x1/8" chains are compatible, but then states that these thicker chains might not fit through the tensioner (its a retro-fit speedhub). DOH!

So my question is this - which 8sp chain fits? And, how is this descibed in the usual on-line bike shops (eg. Wiggle). PS. I want a mid range quality chain.

Thanks in advance
