I put 2x9 Microshift brifters on my son's bike. They have a short-reach version and a normal reach version. I have the short reach version. However, I feel that it's not particularly shorter reach than the Shimano ST3300, 3400 series, which have a slim body and a reach adjustment screw. My kids hated the thumb switch of the ST3300 and prefer the paddles of the Microshift though. The Microshift brifters shift cleanly and crisply, but I feel the small paddle digs into your fingers when you are braking. My kids have no such complaint somehow.
