I dropped my chain quite a lot on a recent Alps trip so would like to get a chain guide. I’ve had a look on CRC but I’m a bit lost on which are compatible. Do they cover a range of chainrings or a specific combination?

I’m running XT 2 x 10 (24/38) ISCG 05. I’ve already got a clutch mech in case someone suggests that.

Bike?
http://www.c-guide.org/ these are great but I have a cannondale prophet so it don’t fit.

C-Guide sounds perfect.

Cool, I’ll take a look. I was also looking at the Blackspire Stinger it says it’s compatible for 32-40t. I was wondering if that’s for just the big chainring or does it mean for a 32/40 combo?

No I have a Blackspire Stinger no that’s just the ranger for the bigger ring I think. I have 22t/36t on front.
But if I could I would go for C-Guide because it cheaper, lighter and easier to put it on and take it off.
