I bought these shifters to replace the rotary shifter on my Mongoose Dolomite fat tire bike. It was a quick, perfect fit. I had to buy another set of grips also, as the rotary shifter side had a short grip, but that was easy also. The old shifter did not index quite right and you could hear the gears clicking a lot as it was between shifts. It is a seven speed bike, so I only needed the right shifter, but the price was unbeatable for the pair. Now, the bike shifts perfectly and the indexing is right on. No more gear clicking. I did need to tilt my brake lever down to make room for the shifter, but that was easy enough. I also like the push button shifting to go up on the gears. All in all, a perfect purchase for this bike.

I don't actually know a lot about shifters. I needed new ones and these are the ones my boyfriend said would be best so I bought them. I do know that they work well. They do exactly what they are supposed to do, they are easy to use and they look great on the bike. I would definitely buy from this seller again. They were delivered right-on-time and were in excellent condition.

My disclaimer: I bought these and installed them on a 1982 Raleigh Rapide with its standard 10-speed (2x5) gearset, which might seem strange. I received the bike for free, but wanted to upgrade from the "suicide shifters" (name given to these by other people online, but basically they were 2 levers with no markings, just shift by feel...).These Shimano shifters are designed more for some of their 21 speed (3x7) gearsets, but they can be adapted for use on other bikes with careful adjustment. They come with quite a length of thin steel-braided cable already attached to the shifters. They are a bit tricky to get into place on most road/race bike style handlebars (especially if you have brake levers that sit further out on the handlebars), but removing the bolt and bending the clamping surface underneath allows just enough clearance. After that, overall setup is relatively easy. In normal operation, the shifters work very well, shifting up a gear at the rear could not be much easier with the button, while shifting down at the rear is straightforward as well. The shifter for the front gears is a little stiffer (though not surprisingly stiff), but still performs well. I would recommend these to anyone, as they have helped make my bike much more enjoyable.For those of you who just might want to try something similar and are wondering how mine is set up for 11 less speeds, they best approach for the rear gearset is to adjust the cable based on your 5th/6th gear with the indicator in 7, and then confirm that it will change exactly to a gear as you go down. While you will end up with an offset, it's a lot easier than trying to get it into 1 at your first gear, as it requires 3-4 hands to do this. The front gear can really be set up to your preference, and mine is much more normal in operation.

I recently bought a Specialized HotRock 24 Road bike for my 8 year old son. This bike, along with the Trek equivalent and his older Trek 20" bike all come with grip shifters. I truly wish all of these bikes would STOP shipping with grip shifters. I even have a hard time shifting my kid's bike into the big ring. As an 8 year old, he just doesn't have the grip and hand strength necessary to move his bike into the big ring. One of the main reasons we bought the bigger bike was because he was maxing out what he could do with the smaller bike and needed more high-end gear ratios. The stock grip shifters made it so he couldn't even use them.Enter these shifters.First, the price made it a no-brainer. They're not like my SRAM Forces that would set you back over $1K. They are dirt cheap and surprisingly well made for the money. Yes, they're big. Almost comically big. But that makes it easier for a kid to work them. (Don't worry - if you're an adult, they won't look stupid or out of place, just big).It took me about 20 minutes to replace the existing shifters with these new ones. Coming from grip shifters, the handlebar grips were quite small, so I also upgraded to full-length grips but that made removing the existing grips easier since I didn't care if I damaged them. Though I didn't.Using the existing brakes and cable housing (this is a newish bike so nothing wrong there), I ran the new cables through, attached to the derailleurs and made a couple minor tweaks to tension and voila. Done. I did wind up swapping the order that the shifters and brakes went back on the handlebars, but only because of a different form factor.The right set shifts beautifully with no mis-shifts. The left side takes a little to get used to but the great news is, since it's non-indexed and you have a lot of room to play, you can work your front derailleur and eliminate chain rub. Normally, when my son was in his middle chain ring up front, he would get rub on gears 1 and 7 on back. Now he can easily adjust and keep from getting the chain rub.In all - a HEARTY recommendation for these shifters. Well worth the money and a must-have for any kid's bike. Don't hesitate to try the install work yourself. Just grab a pair of cable cutters (Park Tool ones work the best, but if you don't want to spend the money, a solid pair of wire cutters may work) and a couple ferrules (a few cents a piece) and get to work.

Recently purchased these to replace the grip shifters on a cheap mountain bike. They work quite well, even with off brand derailleurs (x-trac?). Installation was straight forward following the instructions. Adjustment was easy enough. My bike has non-compression cable sheaths, though they are old and due for replacement, so the indexer works perfectly.The product comes with an indexed right-side shifter (rear gears) and a non-indexed left-side shifter (front gears). Steel inner cables are included and were plenty long enough. The instructions are printed in several languages but the print is somewhat small and not very well translated. If you have never worked on your derailleurs before, seek help from a good bike mechanic.Also in the box was a selection of short outer cables. I presume to help with cable routing. Some cable lube would have been a nice touch, but was not included.Please note. Do not cut the inner cables until you are sure of your installation and adjustments. The cables are quite strong and will need special cable cutters to cut properly. After cutting the ends should be soldered or a cap crimped on to prevent fraying.The only downside to these shifters is that they take up a fair amount of room on the bars. While the attachment clamp is fairly narrow the body of the shifter extends towards the center. If you have a lot on your bars, be prepared to juggle things around for best fit.
