Shimano Deore FC-M5100-1 crankset - 10-speed with only one chainring

The Shimano Deore crankset FC-M5100-1 are cranks with only one chainring, which was designed for 10-speed and 11-speed drivetrains. The chainring is not mounted directly but via a 4-arm spider. You can choose between 30 and 32 tooth. Thanks to the 2-piece construction, a balanced ratio of stiffness to weight is ensured.

2-Piece Crankset
With the 2-piece designed cranks from Shimano, the right crank arm is precisely matched to the interaction with the bottom bracket. This increases the stiffness and keeps the weight low. Further spaced bearings also improve strength and contribute to more pedalling efficiency. The precision manufacturing of the bearings ensures easy installation and low maintenance. 2-Piece cranks share a 24mm axle diameter with Hollowtech II cranks, so they are also compatible with Hollowtech II bottom brackets.

I will tell you the opposite, Shimano played a trick and decided to make the system fit all standards in one fell swoop, which brought problems to our users! If you have chain line 49-49.5 then this system will have 51-52 and in first gear there is a very strong skew! No carriage spacers will help you. Buy an old system in this case, so as not to run into a problem. I have 1/10 and I had to install another manufacturer the chain is thicker by 2 mm then I got a more or less even chain line. Well, or put spacer rings under the bonds. And this is a collective farm system. Be more attentive comrades.
