Mine is similar to this is it ok?

Is this picture taken with the chain on the large cog at the front and at the back?

If so the derailleur angle is OK.

Thanks for reply..

On my bike that is the angle if the chain is in both big rings - (it's a tiny bit more acute)

Assuming both big rings have 50 and 25 teeth, shifting to your small chain ring (34t) and a middle sprocket (I.E. 17t) will give exactly the same ratio with a better chain line (read: less chain and deraileur wear and possibly less likely to drop a chain)

you're welcome

Cheers Steve - I've been looking into avoiding cross chaining so will follow your advice
