Compatible With My Pashley Parabike?
11 Oct 2014
Could you tell me if these chain tensioners can be fitted to my Parabike please as it has a Sturmey Archer 5 speed hub? Thank you.

Unfortunately these will not fit your bike, they are designed to fit to single speed track bikes with horizontal dropouts.
