Shimano Shift Lever, SL-M315-7R, Right, 7-Speed RAPIDFIRE Plus, W/Optical Gear Display

I replaced the twist-grip shifters on my bike with these shift levers and am very pleased with how they perform. They are much easier to operate and provide better control of shifts.

I'm 77, former occasional marathoner, couldn't run because of bad hips, started walking had to stop because of bad hips, ortho doc said ride your bicycle. My old hybrid bike had a Shimano grip shifter and wouldn't you know it, I developed arthritis in the base joint of my right thumb and could not shift because of the pain. I read up on this shifter, watched a couple of YouTube videos, and bought this one. I am not a bike mechanic though I do play one in my garage. Took me all of 25 minutes to remove the old grip shifter, install this one, and go for a test ride. This shifter does not come with instructions, so, here's what I did. You will need: -- a 10mm socket for your ratchet handle; -- a set of mm size Allen wrenches, I didn't notice what size I used, just pull out a set; -- flat-blade screwdriver; -- wire cutter; -- big pliers or crimper of some kind; -- spray bottle with a little rubbing alcohol in it; -- a bike repair stand -- if you do any biking at all, you need to invest one of these - it's the stand you see in the bike shop where they lift the bike off the ground and clamp it onto the stand. When this shifter arrives from Amazon, in the box is a tiny silver thing wrapped in plastic. DO NOT LOSE THIS THING. DON'T LOSE IT. GOT THAT -- DON'T LOSE IT!! 1. Put your bike on your repair stand. Trace the cable from the right-hand shifter to the derailleur. The cable is in a black housing that you MUST re-use. 2. Standing on the RIGHT side of the bike, with your LEFT hand on the pedal and your RIGHT hand on the shifter to be removed, pedal the bike forward, shift into 7th gear and leave it there. 3. With your smartphone, take pictures of the entire route of the shifter cable from the shifter to the derailleur. Also take a pic of where the cable is connected to the derailleur shifter at the rear chain sprocket. Pay special attention to where the housing goes into/through clamps welded onto the bike frame. 4. Stick a flat-blade screwdriver under the hand grip where it joins the shifter, pry the hand grip up, hold it up, spray a liberal amount of alcohol under the grip; do the same to the underside of the grip. 5. Find the mm Allen wrench the fits the screw clamping the sifter and the handbrake lever to the handlebar. Loosen them slightly. 6. Now that the alcohol has loosened the handgrip, pull it off - you may have to work around with the screwdriver blade, but it will slide right off. 7. Go the rear derailleur and find the screw that clamps the cable to the derailleur. Will take a 10mm socket, loosen it. Cut the little tip off the cable; pull the cable up through the clamp so it's free. 8. Go to the front of the bike, grab the old shifter, loosen it, pull it off the handlebar, then pull and pull and the cable will slide out of the housings and eventually pull free. 9. Now -- clamp the new shifter in place, tighten onto the handlebar with the Allen wrench. 10. Thread the cable through the housing pieces. Be certain to hang/insert the housing pieces into their brackets -- see, I told you to take some pics before you took it apart -- refer to the pics. 11. When you get the cable pulled all the way through, check to ensure the lever is tightened to the handlebars, then, go to the back of the bike and PULL the cable through the clamp on the derailleur shifter -- make certain the housings are in place. Pull the cable TIGHT. 12. This will take more hands than you have, but you can do it -- hold the cable TIGHT through the clamp, using the 10mm socket tighten the cable to the derailleur shifter. 13. Stand on the right side, left hand on the pedal, right hand on the shifter, pedal the bike and try to shift. May not work. If it doesn't work, put the shifter back in 7, loosen the 10mm nut, pull the cable through the clamp, move the derailleur shifter up slighty, and tighten again, lifting up on the derailleur shifter as you tighten the cable. Took me three times and on the third time, it shifted smoothly. 14. Remember that little sliver thing I told you DO NOT LOSE? There will be several inches of cable hanging out under the clamp in the derailleur shifter -- cut that to about 2 inches long, slide that little thing onto the cut end of the cable and crimp it with pliers or a crimper. This thing keeps the cable from raveling. 15. Install the hand grip back onto the handle bar -- use a hammer to tap it on. Grip the handgrip, see if you can operate the shifter up/down, and THE BRAKES. Loosen, re-position, tighten the brake lever and shifter to positions on the handlebar that are comfortable and safe. And now it's Miller time. Nothing to it. I just ordered a 3-position shifter to replace the old handgrip shifter on the left side.

I'll start by saying I haven't ridden a bike in almost 40 years. I purchased a 7 speed myna bike a few weeks ago, mostly to bond with my kids, but also to get back into shape. Unfortunately, the bike came with a twist shift. After a few days of accidentally shifting gears all the time, I had enough. A few days of research led me to this shifter. Now, while I'm generally mechanically inclined, multi-speed bike gears is fairly new to me. Having said that, I had this shifter installed and fully functional within 30 minutes of delivery. The hardest part is threading the cable through the guide tubes. Other than that, it's so simple. I may need to tune the derailleur, but that's not an issue of the shifter. If you're on the fence because you think it's beyond your skill set, it's not.

I didn't know what I was missing until my previous twist shifter broke and I had to get a replacement. This shifter is amazing!!!

works as advertised

I bought a Rev 20 kids bike from REI and none of the kids could shift to 1st gear because it was too much force to twist it to gear 1 and when they did it would hurt their hands. So then I switched it up to a TX30 which is a great upgrade but still not great ergonometrics for them to push that hard with their thumb. I looked around for other upgrades and found their weren't many options for a 6 speed but this actually ended up being compatible with very light tuning. Plug and play with the handlebar setup and it fits perfectly with standard lock grips. Such an amazing upgrade. It's so easy for them to use and so far they've abused it pretty well on some bike drops and it holds up. I'll be replacing every bike with any shimano twist shift with these. RV200 was just too tough.

Really great product to bring back life and functionality of your old 90's bikes that need new shifters! Smooth action, reliable shifting and great product at a decent price. These trigger shifters, in my opinion, are far better than any grip shift devices, and they work on a wider range of handlebars.

Works as it should.

Excelente calidad se lo puse a la riprock 20 de mi hijo ya que el shift de circular está más incómodo para un niño! Y a funcionado súper bien original y excelente compra! Además que se ve mejor apariencia ahora que antes! Compra no te vaz arrepentir !

Easy to fit, arrived 4 days early (came from America to uk)

Great quality and quick delivery

Really great product. We bought them to replace the very poor grip twist Shifters that came with our daughters bike. These were the perfect solution! Very smooth shifting and easier to use.

Muy caro
