Just setting my bike up for a long trial tomorrow (Rev4t) i have gone to sort the chain as it seems to be a little slack, but when i tightern it, it seems a little tight. i am unsure which would be best any help would be good, its not life of death but i always prefer to ask. thanks guys.

Just knock the snail cams up a notch, not all the way? Or am i missing something?

Hi.I,ve always reckoned on being a bit slack rather than tight.Also I have had cams that go from too slack to tight like you.I find the notched ones bad for this because you go from one set position to another,ie too loose to too tight.Cams without notches work better for me as you can go inbetween notches if you get my drift,so only move back wheel a wee bit.I,d go with too slack and not worry about it too much,within reason.I think too tight puts more wear on the sprockets.I know the beta manual says 20 mm but I often have it between that and 10 mm.Have fun at the trial

Cheers guys, slack it is.
