works for me

I replaced my stock shifters with both left and right shifters. They both were very easy to install and setup. Great product for the price!

Quality made.

I have put a pair on my road bike and I used them on a bike trip in France. They never let me down, I love this shift.

Best shifters!

Great inexpensive shift of entry level shifters. Worked great to replace worn out twist shifters on a mountain bike.

Great shifter, great value

This is a good shifter. It works perfectly and now I can shift with no problem. It wasn't very difficult to install, and it made such a difference out on the trails. Couldn't be happier.

Good replacement shifters.

Excellent replacement/upgrade shifters. These are at the lower end of Shimano's range but would definitely be an upgrade to the twist shifters or brake/gear shifter combinations. Nice smooth up/down changes together with the benefit of the the 3-gear multiple shift down facility on the right hand shifter - very useful for those sudden hills! I'm using them on an old 21-speed MTB, as opposed to a 24-speed as it was a lot cheaper for me to get this set than the correct 21-speed set - note left hand shifter is identical, just make sure for the 8-speed right hand shifter that your derailleur limits are set correctly at the back. The included cables work fine although I cannot tell whether they are galvanised or the better stainless steel variety.
