Shimano RAPIDFIRE Plus Shifting Lever Left Only (3x8/7-speed) SL-M315-L

I cannot claim to be a very experienced biker, but I can say that these were easy to install and work well. The previous originals were broken and only partially worked. I do not have years of experience with other competitors, so I can only fairly rate them 5 star in that they were easy to install, work well and were at a very reasonable price and they are well made.

Perfect replacement for front derailleur shifter on an old Raleigh mountain bike. Installation was quick and easy for me as I pretty much have no clue what I am doing but I am learning as I go. I really got a kick out of the chain gliding onto the largest chain wheel as I clicked 1 through 3 and 3 through 1 over and over. The old Shimano shifter had pretty much fallen apart. Maybe it could have been salvaged, I dunno. This was an easy solution to overcome some procrastination and get the bike working. On to tuning...and new handlebar grips.

My bicycle originally came with grip shifters which I replaced them with shimano thumb shifters (the silver one in the picture), but the thumb shifters stick out on top of the handlebar, which not only looks strange but is also easy to bump into, especially when transporting the bike in the back of my car. This shimano goes under the brake lever so it does not protrude. I was initially concerned about its compatibility with my non-Shimano brake levers, but it fits fine. The shifter works well—I have both sides—and it’s easier to shift compared to a thumb shifter or grip shifter. You use your thumb to shift with the front lever and your index finger for the rear lever, which operates between the handlebar and brake lever. As with most Shimano products, it came in a blue/silver box with the shifter cable pre-installed and a cable end cap included, but no cable housing.

Buyer beware. Do not buy the "unisex adult" Shimano shifter from other sellers. It's THE SAME EXACT SHIFTER as this one. It's not BIGGER or STRONGER. The difference is the price! This shifter and the matching 7-8 speed Shimano ml-315 are great. Notice that they are like 15-20 bucks. The "unisex adult" has it listed as being larger and heavier than the other ml-315s. It's NOT. I got ripped off. I COULD have returned it but I had a race to attend to. Also, be careful of shifters being labeled as "Atlas". Shimano DOES make an Atlas, Atlus, shifter however their shifter says Shimano on the shifter itself. The ones that say Atlus are NOT Shimano's. They cost about 4 dollars less so people buy them. ALSO, be careful of buying from ebay. They have TONS of fake shimano accessories. Ok, now for the shifter. It works PERFECTLY. It's all you need to work with ANY Shimano 8 speed. Just be sure to put the adjustment screw located on the shifter itself about half way so you can make adjustments afterwards. Drop the bike to its highest gear (8) and drop the front derailleur to the smallest chain wheel. If your derailleur was tuned before the shifter swap it will work pretty much without any adjustments. Oh, be careful where you put the shifter. If the brake lever it to low, it will be difficult to drop down gears and chain rings because the down shift lever will hit the handlebar grip. I did a conversion from grip shifts to rapid fires and I couldn't be happier.

I have 3 chainrings in the front and 7 cogs in the back. Along with this shifter I also bought the matching shifter for the other side and two Shimano derailleurs - the Altus FD-MD310 and RD-MD310 because I wanted a matching groupset. Installation was easy and it was mostly shifting out of the box. I have to adjust indexing but I can tell it is running smoothly. If you are using these for an ebike I would think twice because I'm having a lot of problems getting everything to clear the brake levers and throttle body and such. For a regular bicycle I'd say they're decent for what they are, just don't expect them to last forever because these types of shifters will break eventually.

Works perfectly on my mountain bike

Works great! I replaced some 20 year old Shram Axis grip shifts with these and so far they work well and are sturdy and well worth the value.

This SL-M315-L shifter fits with the Shimano SLX BL-M7100 brake lever. My bike used a grip-shift for the chainrings, so this shifter was necessary when using the 7100 brake lever. Shifter works fine. The indicator does not. It initially went to 3 yet while chainrings 2 and 1 are used the indicator is at 2.5 position. Sometimes I can pound on the handlebar and the indicator will go from 2.5 to 1 when using 1 chainring. I returned an initially ordered new SL-M315-L shifter because of this condition. This is the 2nd shifter which is repeating the same condition - indicator will not return to 2 or 1. One other observation: The clamp bolt had too much green grease applied to it. See photo. I'm wondering if the inside of the shifter also has too much grease causing the indicator to be sluggish. Possibly a new employee without proper training and monitoring. UPDATE 2022 Aug 10th: The indicator mentioned above in 2nd paragraph is finally working properly. It is moving as one would expect and is consistent. I again say I believe there is too much grease internally which caused this initial lack of proper indicating of the chainring.

Llegó un día antes de lo estipulado y tal cual como está en la imagen te llega
