Nice bike! I really wanted one of those small IRO frames because I'm a short-arse, but couldn't find one second hand and they were too 'spensive off the website :(
It looks like a pretty sweet set up already to me, why do you want to change it? Do you mean replace EVERYTHING like the wheels and cranks and brakes? Personally I'd keep it how it is and just take it to Armortex and get it sprayed an awesome colour :)
