Thanks for the advice and response.
I might well try a different ratio as it will be pretty much road based.
The colour is Fire Engine Red, finished with a clear coat, I went with no decals for a clean look.
Before anybody asks where I got it done, I am currently living in the US, so got it coated over here, $125(76 pounds) for the job.
The FC EBB was $160(97) all up, it's easy to adjust, but I made two permy pen marks on the fluted adjusters to align both side if the BB.
If you are going to change sprocket sizes I would probably recomend a half link.
The chain is a KMC 9 speed and so far has been ok and quiet.
I posted a link to the FC EBB in an earlier forum thread, but it's easy to find if you google.
