Good quality at reasonable price
I rehabilitate a lot of bicycles, and when I need a replacement part for an upgrade I regularly use Microshift components. They work great and are cost-effective.

Great grip shift replacement for the little ones
Fantastic replacement for grip shifters for kids. Took 10 minutes to swap out the grip shift on my son’s 24” mtb. The shifting is so much easier for him now, for the price you can’t beat these. I find the little ones can’t twist the grip shifts up easy enough. These fix that problem.

Micro Shift shifter
The first set I ordered the right 7 speed shifter worked with no problems. The left 3 speed shifter for the front derailleur would move one position and slip. I sent them back for a replacement. The replacement left shifter worked this time.

Great budget upgrade
Used these to upgrade an old bike that was equipped with 21 speed grip shifters. These thumb shifters were a breeze to install and tune. The thumb shift design allowed me to keep my existing brake levers. This kit comes with both left and right shifters and new cables.

Can't be happier for the price
For the price, these are really well-made. The picture makes them look a lot smaller than they are. I do wish they were a little quieter, and the short lever was a little easier to reach. They're otherwise an amazing buy.

Lacks front trim adjustment or option to run friction
Easy to install rear shifter worked great with rear mech. Front shifter different story. Cannot get it to index properly with my front triple- zero trim adjustments let alone friction option is available. Very disappointed with the lack of trim adjustments especially for the middle ring. Chain rub on half the rear cassette and I know the front mech is positioned correctly.Had to order a friction thumb shifter for my front mech/crank combo.At least this is an inexpensive shifter set so I’ll be keeping the right shifter for now and running a different friction shifter on the front.-A Retrogrouch

Great replacement for cheap twist shifters
These are a low budget yet effective replacement for junky twist shifters on department store bikes. They work great with the factory derailleurs and index the shifts without the annoying grinding of the cheap twist shifters they replaced.
