front chainring shifter question

[Cataboo]

You could do it... you can set the derailleur screws so that the chain won't shift off if he accidently shifts down from the third gear.

But maybe putting a bar end shifter on his left side would be less work for both of your bikes.

I agree with Catriona that a bar end shifter would likely be easier for him to use. Much less hand strength involved.

I agree also. Plus, the throw on DA front levers is VERY short (and easy), compared to other Shimano components. So assuming his fingers can reach as far, then moving to other brifter-type Shimano shifters would make things worse.

Instead of bar end shifters, can he rig it to take a downtube shifter on that side? I don't remember how they used to rig Lance's Treks. In the Tour, he'd use a front DT shifter because it provides more trim.

Depends on what motion is easier for him. A downtube shifter you grab between thumb and hand and move with your wrist and arm. A bar end shifter is moved with the outer fingers and wrist.
