I have an orange hitman with a single chainring on the front (gears at rear, not singlespeed) that seems to be dropping the chain far too often.
It has no chain device/ tensioner fitted which I assume to be the problem.
The bike is pictured on page 27 of this orange brochure http://www.orangebikes.co.uk/brochures/original/brochure_2005_screen.pdf where it has a chain device fitted.
Can anyone tell me what this is as I am looking to buy one or something similar to stop the chain coming off and don't really know where to start (is it a guide or tensioner or are these the same thing?)
I am told the bike has ISCG tabs which are used to fix such a device to.
Would something like this solve my problem http://www.chainreactioncycles.com/blackspire-stinger-chain-tensioner-green-2013/rp-prod54361
