Ivan

My bike comes with Shimano MT500/MT510 cranks, would they fit without any additional changes?

Answer of Nikita

I think answer is No! You need to change buttom bracket for this crankset , and you will also need to change chainring.

José Miguel

I want to buy the Shimano SLX M7120 12s Hollowtech II 165mm cranks. Do they come with or without a chainring? I see that the chainring type is direct mount. If it doesn´t come with a chainring, what tool do I need to buy to tighten the direct mount chainring?

Answer of Nikita

No, kit only include cranks

Answer of Bartlomiej

The crankset doesn´t come with a chainring. You´ll need a Shimano TL-FC41 or another manufacturer´s Direct Mount wrench. The chainring itself can be from any manufacturer, but choose the offset that matches your chainline.

I have a Scott, bottom bracket measurement 92 mm, what type of hub do I need to mount the Shimano m7120 cranks?

Answer of Gabe

Any pF92 or BB92 bottom bracket will do by various manufactures but commonly by Shimano or Race Face. Depends how much you want to spend...the higher the price, the supposedly the higher quality bearings.

Franco

Hi, I would like to know if the shims/spacers are included to compensate for the size of the longer shaft, I mean for the transition from slx 7100 to slx 7120. Thanks

Answer of Ana Cristina

I apologize for the mistake, I was checking and right at the bottom of the box are the 2 spacers. There is also the ring to fix the chainring and the piece to hold the crank.

Answer of Giovanni

YES, spacers are included.

Is this crank compatible on a 2023 Specialized Stumpjumper evo?

Answer of Cilia

If your specialized uses a SRAM DUB Bottom Bracket then the answer is no as the spindle diameter is 29mm and the Shimano crank uses a 24mm spindle. However if you have a Shimano Crank on it at the moment then it will fit. It all depends on the Bottom Bracket.

Is it possible to fit a 36 T chainring?

According to Shimano information only up to 34T

No, it is not. FC-M7120-1 only allows for 30T, 32T, 34T: https://bike.shimano.com/en-AU/product/component/slx-m7100/FC-M7120-1.html

No, a 36T dial will be too big
