I really am considering buying a triple and then jsut removing the granny gear, but how much trouble would this then raise for me?

I'm not sure how difficult it would be, sure you could make it work, you'd have to check the front cog sizes, Triple doesn't just mean extra cog, all 3 front cogs may be different to a double.

Sorry I will read the whole thread next time.

Yes you can remove the inner chainring if you want to (and put it back on later if you change your mind. The outer 2 chainrings on a triple are generally the same as a double--typically 53-39 (-30 for the third, inner ring). The only other meaningful difference is that a triple typically has a 118.5 bottom bracket, vs a 109.5 for a double. This gets into the whole Q-factor thing which you can research elsewhere if you feel compelled to. I've gone from a double to a triple and have not had any issues in this regard. (I'm one of those older guys referred to above, and my routes typically involve major hills.) Bike fit is of major importance...not just frame size, but saddle height and fore/aft adjustment, stem length and bar height/width. Failure to get fitted properly can result in major ongoing knee pain.

FORGOT TO MENTION: You will have to adjust the front derailleur stop (and maybe cable tension also) after you remove the inner chainring so that your chain won't jump off to the inside where your 3rd ring used to be.....
