Fontyyy,

I used to run a 15/40 on mine (how it was when I got it) but when I recently changed the chain and sprockets I just ordered a standard set from Apex and got the 15/44, I agree its far too low and whenever I get on any kind of open road I am wanting to change gear again. I will probably change back to 15/40 in the near future as it had no problem pulling in top with this set up.
