Cyclists with upper limb disability -- bike modifications?

[elviento]

A good friend of mine has only one arm (plus 20% of the other to be more exact). And he competes from time to time in triathlons, using a flat bar road bike, with one of those touring bike handlebars.

I just can't help thinking there's gotta be some ways to optimize the riding. I have seen some people mounting brakes on one side to facilitate braking (see below). Are there other modifications that can help with the comfort and control, or dare I say, aerodynamics?

I am thinking TT bars might actually be quite useful when the elbow is close to the center anyway?

this would work with mechanical dics..

it at least gets rid of one brake lever, i also remeber sachs making a gear hub with a cassette carrier and i think that all worked of one shifter, something like 3x8 or 3x9 ?? but this is a while back ...

not as racey..

with saying that i suppose the the electric shimano shifters make those conversion very easy and when you compare this to buying a full custom bike from a specialized workshop it might even be cheaper ?

Seems like an ideal use for sequential Di2.

It would be really refreshing to see electronic shifting utilised by someone that could actually benefit from it as opposed to just being able to afford it.
