microSHIFT Advent "Super Short" Flatbar Groupset, 9spd

Upgrade on my folder

Nice thumb shifter, smooth and precise derailleur and a good range for my 406 wheels.

Perfect for my kid's 20" bike!

Got this groupset as a replacement for the SRAM 7-speed on my kid's 20" bike, which had been thrashed to heck by his older brother and barely worked anymore! Easy install that went on and indexed without a hitch. HUGE upgrade with the extra climbing gears and clutched derailleur for rough trails and jumps. The shifter is easy for small hands to control and has a nice positive "click" action. Smooth, quick shifting through the whole cassette. Probably doesn't get much better than this for small wheels.
