the suggestion , get out a half round file and remove material from the brake lever body, where it contacts the bar, so the whole lever angles closer to the rider..
does have merit...
Shimano has wedges of molded rubber, that get included, in the lever, on bikes , so the lever once released, the swing- arc,
does not fully go out of reach as Much as when it is not inserted..
Often does not make it onto the bike on the shop floor
Hang tag bag not big enough for everything, touch up paint vials and lots of things in the shipping carton left off..
So ask for them when you buy the bikes..
