Hi Folks,

This is probably a daft question but here goes anyway:

I have an '06 SX Trail with a Truvativ Howitzer BB..I'm looking to replace the current Blackspire chain device with a Gamut (the Blackspire doesnt work too well!).

Looking on chain reaction they have a couple of different guides:
Old ISCG and ISCG 05.
How can I tell which I have?
Is it as simple as anything made after '05 has the '05 ISCG?

Cheers
Dave

    Measure the distance between the holes on the ISCG mount, then compare them to this diagram

    Thanks for that - turns out it's old ISCG .
