It was so much fun to get these and put them on a beater bike. After a month, the one for the front derailleur busted, so I can't shift to the larger gear on the 2x; when I move the lever, it just moves the entire mechanism so it's all swiveling in the housing. For the rear shifting is still okay, but I find that it sometimes moves itself into smaller gears if I'm doing a bit of a climb.

For $14, I'm not complaining, and it's not worth the effort and expense in shipping to goof around with a return. But I'm definitely eyeing more robust friction shifters from here.

Very easy to install and they work great on my 1x7 townie.

Downgraded review because I managed to break one of the shifters by forcing the lever.

This pair of shifters runs a Shimano Shadow MTB derailleur on a 10 speed cassette in the rear. I know they are advertised to work on 9 speed derailleurs but I have had no trouble running a 10 speed Shimano MTB rear derailleur and an old Suntour front derailleur on a RaceFace triple chainring setup. The bike is a 3 x 10 speed setup. No problems, no broken parts, good repeatable shifting all the time. That said the little bail on the friction adjusting bolt is not up to the task of tightening the rear derailleur shifter enough not to slip. I have to use a phillips head screwdriver to set this tension. Once set I have never had it come loose over a period of a couple of years now. The front derailleur shifter has been a great performer with no issues. For the price these shifters are a home run in all respects. Are there better shifters out there, yes. Are better shifters worth the price, maybe. Will these shifters get the work done for a very low price, yes. A couple of pictures of these shifters in service on my early 80's Nishiki Sebring.
