the leverage is a bit less MA than your aero brake lever on the end of the cable..

but that means the brake's actuation ratio, moves to the rim with less lever motion.
still can effectively stop, but feel is different..

[my older ones were CNC cut , now the lower cost current ones are smoother shaped levers ...



There are some brake levers that bend closer for smaller hands, to reach from the drops .

dont see the same from Shimano.. there are rubber wedges to put in their brifters
so they dont open so far to reach.. .

currently, there are short ramp bars too so brake lever hood is closer to you. given same stem length..
+ of course different stems..

a good bike shop can help you dial in the fit and order the parts
