[Closed] Which 42/28T Chain Device?

Truvativ [url= http://www.bikester.co.uk/225258.html?_cid=1_3_2_2111_2140_2425_225258_&c=18#chain-guide-chainguide-boxguide-team ]Boxguide[/url] would work, but it won't tension the chain in the 28T chainring. Although you won't be descending in that ring so it wouldn't be a problem anyway.

You'd need an ISCG-BB adaptor though, now I think about it.

Truvativ x-Guide or MRP 2X

Truvativ looks the better fit with your X0's

Thanks for that guys!

I'd buy the Truvativ X-Guide but I can only find these two:

These obviously won't go with my bike:

Need to find the device without the red X0 on it......
