I have just built a rather nice Santa Cruz Chameleon with a 1x9 set up, the front ring being 38 tooth with an MRP chain device on the top of the ring (like a front mech)
as cool as it looks it isnt very practical for me, took the bike down lorsdwood in Southampton last night and I struggled on the rooty up hill sections so I decided that I need a double ring set up, Im thinking 22/36 with a bash ring... all bits have been bought including shifter/front mech and should be with me by Monday...
The question is, would it be beneficial to get a chain device for a double ring set up?
Im thinking of something a bit like this? http://www.ebay.co.uk/itm/Blackspire-ST ... 1240wt_924
I think this one in particular is for single ring but does anyone know of any good (reasonably priced) tensioners I could get for my bike to fit my (in the post) set up?
I generally ride single track/xc and some light jumps/light freeride/DH but nothing massive as Im old (31) and don't want to break myself
any pointers would be very much appreciated!
