SENSAH STI Road Bike Shifters Double 2×7 Speed Lever Brake Bicycle Derailleur Groupset Compatible Tourney Triban(2 * 7s Lever)

Used these to convert my fat bike to a "gravel bike". I kept my 1x11 MTB drive train so the left hand gear cable is not connected. Installation was a breeze. Couldn't figure out how to remove/replace gear cables so I wound the LH cable around under the hood and bar tape so its ready if I ever want to add a front derailleur.Note: these are road shifters so unlikely to work well on MTB derailleurs without a ratio converter like Wolf Tooth's Tanpan.So far I find the brake and shifter operation to be smooth and predictable. The hoods feel very natural and comfortable. The only issue I have had is that I occasionally use the bike on technical single track (not what I built the bike for). During steep and bumpy descents with a lot of "white knuckle" braking I find I have inadvertently changed to a higher gear. If the descent is long enough I'll be in top gear.

I have always enjoyed trying new stuff. After well over 25 years of using DuraAce I was pleasantly surprized by brifters of this quality and functionality.The right (rear) shift lever required the usual amount of fiddling with to dial it in for precise shifts but once done shifts are crisp and accurate. The double click to shift up the cassette took some getting used to but became natural after a couple of rides. The left (front) shifter Is an absolute joy to use, there are 4 clicks available for precise positioning making chain rub a thing of the past.All in all I say these are a great value and a fine working set of Shifter/Brake levers.

I was worried when I received these and both shifters had R7 marked on them. Usually there's a R7 and a L2. After close examination there was a left and a right shifter but I could never adjust the left shifter properly. It requires a long full shift to move the chain to the large chain ring and a double click to bring it back to the smaller gear. Not sure if this is by design or not. R7 lever works perfectly. Very smooth and quiet.

Installed on a 9-speed Dura-Ace bike where the right shifter broke. Decided to try these instead of going the used/eBay route. Very pleasantly surprised! Shifting is quick and accurate. The one-lever design is great and easier with gloved hands. I've ridden a couple hundred hilly miles since installing and all is fine. One quick adjustment needed via barrel adjuster in back but likely due to cable stretch, not the shifter. Front also shifts well and has one mid-point position. I like the hood design better than the old Dura-Ace. Brake action is smooth and drama-free with good feel.Installation instructions are almost comical (including smiley faces indicating how to do things properly) - think Ikea, not Shimano. Read other reviews and most questions will be addressed. If you are new to the installation of brake/shift levers, watch some videos first.

I originally loved these brifters. It was a bit of a gamble knowing there was an Achilles heel in these, a small plastic part that breaks basically rending it useless as it won't shift after. Supposedly this was fixed so I bought the brifters. They worked so well until about a month ago when the right brifter made a cracking sound and the shifting hasn't been the same since. It's getting worse and now I am planning on saving up to buy modern Claris shifters. I'd advise against these. Well see if the seller reaches out to try to make this right.

I have now installed Empire on two bike one with over 5K mile issue free, I have Quantum and Phi on ten speed rigs, Quantum is 11S pull so you have to use Tiagra 4700 for 10 Speed, but Phi is 10S pull and accommodates your existing 10 Speed Drivetrain, I have not used PHI outside of my indoor trainer but so far shifting is spot on and very crisp like all the other Sensah shifting groups I have installed so far. A definite value for your money when set up properly. One Note the front Shifter has huge trims that allow easy cross chaining but until you are used to this may cause confusion and frustration, but are brilliant when in use.

Update #2: ===========I have discovered only now that Sensah has a PHI version of the 2x10.... From the description, the PHI would have worked for a 105 shifter replacement that I was looking for. That's a 'bummer', I do not remember this choice being available when I got the shifters 2 months ago.The 2x10 non-phi did not really work with my Shimano RD 105 10s. It seems to be a 11s pull.I ended up replacing the RD with an Ultegra 11s. That seems to be working a lot better after a first ride, even with my 11-28T 10s cassette. I might need a little bit more fine tuning to have it perfect.I could have re-replaced the right shifter with the PHI, but at least now I am one component closer to a 11s conversion. I will 'only' need to get a 2x11s Sensah shifter, a 11s chain and cassette. I think the 10s chainring should work.Update: ===========After four rides, I have to update my review to avoid misleading people out there.The index is NOT 100% compatible with Shimano 105 (brand new derailleur btw). I spent quite some time trying to fine-tune the index, but I cannot get both the high cogs and the lower ones. That's with a 34/52 + 11/28. The best I could get is to have it works very well from the mid-cassette up to 28 with the small 34 ring. And ok indexing from mid-cassette down to 11 with the big 52 ring. Since I am mostly doing big hills, that works ok. That would be more annoying on flatter terrains.I am getting used to the shifter's big motion. Still many misses.Original review: ===========I have not been able to find a replacement for my Shimano 105 10-speed right shifter.I gave it a try to the Sensah STI. So far so good. The installation was simple. The indexing seems to be compatible. The downshifting works well.However, the upshifting is weird. If you pass the downshifting position, it will upshift. ok, fine. But if you go too far, it can upshift by one or more positions. Or if you pass the downshifting position too slowly, it will downshift. After a first ride, I had many miss-hits on the gear I wanted. I hope I can get used to this shifting design...Also, maybe because it is brand new, the shifter is relatively noisy.

Es un producto que comparado con el precio de otras marcas se ve muy bueno, espero y también funcione igual.
