Will bear that in mind as an option, though I am not sure I could live with the aesthetic when the handlebar bag wasn't present (says the man considering a pink decathlon bar bag)
Yeah, I appreciate what you mean. Bar-end/DT shifters or hidden routing is your only real option. Whatever you do, don't bother using 9spd stuff, it's no better than 10spd in terms of longevity. Better to go for 5700 and have a spare quick link.
