FOMTOR Bicycle Crank Arm Set 104 BCD Road Mountain Bike Crankset with Bottom Bracket and Chainring bolts 170mm Crank Arm

I bought this to replace my outdated square taper BB and crankset that recently died on my MTB, 90% of my riding is done on my road bike so I needed something cheap and easy for my mountain bike.Upon opening the parts were all well packaged, and after inspecting them, all seemed pretty solid, the BB is near enough identical to a Shimano Hollowtech ii maybe along the same lines as a Claris or Sora model. The crank arms are robust and a little heavier than expected but that’s not a big deal. Extras include the chainring bolts and bb spacers.I fitted the bb and luckily didn’t need to to fit any spacers, I fitted my existing chainring to the crank spider and everything felt solid and the chain ran straight after tightening everything up.I tested it on a quick ride mixing up smooth tarmac, gravel tracks and some rocky downhill single track and it performed fantastically, the cranks feel solid and stiff, the previous square taper always seem to feel a bit spongy. Obviously I know that time will tell, and I will update my review in a few weeks/months will further info. But as it stands this is a real value for money purchase, you could spend £40/50 more on an official Shimano/SRAM product but you won’t go wrong here at all. Definitely worth an investment if you don’t want to spend too much, as buying unbranded Chinese stuff can be a gamble but it paid off for me! As I said before I’ll return with a further update after a few weeks of riding but all seems well at the moment!***UPDATE***So 2 months in and it’s still running perfectly! I was expecting the BB to go first but it’s still as smooth as ever, I’ve been on multiple XC rides through both wet and dry conditions as well as rough terrain, I also commute to work 4 times a week using the same bike so it’s had a whole load of use and yep, it’s perfect. I can thoroughly recommend this crankset it’s practically faultless considering it’s unbranded. The cranks are rock solid and can take a huge beating, the BB I’m still preparing to replace as it’s obviously not an official Shimano, but a Deore replacement is only about £10-£12.

I've just purchased this set of cranks for my Son to replace his old square tapered bottom bracket and cranks.There were no reviews, so it was a bit of a gamble and felt it'd be worth it and it was. The cranks and bottom bracket immediately feel great quality and are pretty light.I was pleased that prior to purchase I thought they were a clone of a Shimano Hollowtech 2 system and was utterly delighted that they were when I saw them in the flesh - no chance was I spending hundreds on my teenage toerag!They're now on his bike and have been faultless. I implore anyone who needs to replace a bottom bracket and cranks to upgrade to these (if you're on a budget or want to move on from the square tapered type system).To get this bottom bracket sufficiently tight you'll need to buy a Hollowtech 2 bottom bracket spanner, such as this: https://www.amazon.co.uk/gp/product/B01JHXTIXKContained in the package is a bearing preload bolt which is made out of plastic. I personally think this is a good thing as it might prevent people overloading the bearings, although it's good plastic so maybe not!I did it finger tight - as is the requirement - and then tightened up the other crank arm. The arm doesn't hold the preload bolt in, so I removed it and plan to buy some bar end plugs to block the hollow axle up. This is far from a negative though, as once it's been used to add some "preload" (squeezing the arm lightly against the bearings/bottom bracket prior to tightening the arm up) there's no point in leaving it in.Also, I'll write this as I had a nightmare getting the old bottom bracket out and I'd hope that if others do, this might help. We did it by purchasing this bottom bracket remover for our old square taper typehttps://www.amazon.co.uk/gp/product/B002NGO2EYand then bolted this to the bottom bracket using a washer and the bolt used to hold the old crank arm on.This then meant I could then put the newly purchased 32mm spanner on this bottom bracket remover and stand on it forcing it to undo.https://www.amazon.co.uk/gp/product/B000LFXL1YAlso to help others, the bottom bracket undoes in the same direction you pedal the cranks when riding and this is the same for both sides.

First test ride on my gravel but already noticed some clicking, however it turned out to be the seat post. Cranks seem decent quality but a bit heavy. will see if the BB will be OK over time, so far its fine. I wish I had bought the version with chainring as the one I bought separate didn't match the profile of the cranks. Not a big deal though.

I've converted my 90's mountain bike from 3x8 to a 1x11 setup and this is one of the parts I used. I'm very pleased with the result.

I bought this to convert my main trail bike from a 2x9 to 1x9. The bottom bracket was smoother than the Shimano deore one that was already on there. Aswell as this the cranks are incredibly durable as I took them off a 4ft jump to flat and I am a fairly big guy at 115kg. Also, they were lighter than the 2x Shimano deore cranks I had on there although this was expected as the previous crankset was 2x. Also and additional note if you currently have a Shimano hollowtech 2 bottom bracket the spacers you have on there already is not the ammount of spacers you'll need as the crank spindle is slightly shorter than the Shimano one so take one spacer off the required ammount when installing the bottom bracket.

Decided to purchase these after seeing others use them for switching their bikes to a 1x setup. Came in good time, install was simple, really gave a different look and smooth feel to my bike. Its a good quality product for a very good and reasonable price.

Product was missing one of the chainring bolts. I recieved two female bolts instead of a male/female. Other than that it seems okay for the price.

Ottima alternativa ai marchi più prestigiosi. Compatibile con movimenti shimano. Il movimento di centro è un pò sottotono ma funzionale. Grande assortimento di corone in tutte le dimensioni desiderate.

A la espera de la duración, se ve de una calidad aceptable.

j'ai installé ce pédalier très simplement sur mon vtt, pas besoin des entretoises (73mm) et je l'utilise en monoplateau et le passage d'axe carré à l'hollotech2 est vraiment un gros plus (plus fluide et plus léger. Le boitier est de qualité et l'ensemble parfait.

Passt, wie angegossen. Fühlst sich hochwertig an. Bis auf das Lager: Beim Einschrauben mit einem Hollowtechschlüssel verkratzt der Lack leichter alt gedacht.

Funzionale e leggero, senza infamia e senza lode.
