Best Bike Crank |

Which bike crank is the best?

Cycling can sometimes be a complicated hobby. There are many complex mechanical parts on a bicycle and they are not always easy to understand for an inexperienced rider. The bicycle crank is a good example. This generic term represents a series of parts near the pedals which includes the gears, the crankshaft, the bottom bracket and the spider support. Inside these parts are even more complex parts that keep them working properly. It is best to have a good understanding of a bicycle crank before making a purchase.

Buying the right part largely depends on the bike you own. In general, the best bike crank is the Shimano M361 hybrid crankset, which features three chainrings for multi-speed bikes.

What to know before buying a bicycle crank


Cranks are several parts of a bicycle. All parts reside in one place at the base of the bike. This term can be used broadly to describe all parts of the area. Cranks and chainrings are the most common parts you will see. However, it also includes a bottom bracket, spider hanger, front derailleur, axle and several bearings, bolts and washers. When buying a new crank for your bike, the chainrings and the crank are the most important.

Crank arm length

Before you start shopping for a new crank, it’s important to know what length your bike needs. You can measure it yourself by starting at the middle of the pedal axle and working your way up to the beginning of the pedal support base. You can also check your pedal axle on your cranks below. Most manufacturers will engrave measurements on it. The most common lengths are 170, 172.5 and 175 millimeters, depending on the size of your bike.


The trays are the round metal parts with teeth. They are a crucial part of the mechanics as they sit at the central base of the bike along with the pedals and the chain. It works by the chainring attached to the chain which is turned by your pedaling. Single-speed bikes will only use one chainring, while multi-speed bikes can use up to 12 for pro bikes. Chainrings are measured by the number of teeth or tips they have. For example, 48/38/28 is a common measurement for a multi-speed road bike.

What to Look for in a Quality Bike Crank

Aluminum alloy

Aluminum alloy is a very strong metal. It is also very light compared to similar metals. This makes it the perfect choice for a bicycle crank. It offers enough power transfer to turn your pedaling into speed and you won’t have to worry about it cracking. It can withstand more bounces and bumps than carbon. In fact, many other bike parts are made from aluminum, including handlebars and even some frames. If you are looking for the best quality bike cranks and chainrings, look for an aluminum alloy set.

Bottom bracket included

The bottom bracket is the part that goes inside your bike’s frame. It is a lubricated cylinder that acts as a bridge between each crank arm. Some cranksets come with a bottom bracket. This makes installation easier because you know everything will be compatible. It can be difficult to search for very specific pieces that fit together. It is therefore much more practical to find a crankset with a bottom bracket already included.

Single speed crankset

Single-speed cranksets are the easiest to install. They also offer great quality thanks to their simple design. Cranks for multi-speed bikes have several extra parts, leaving more room for misalignment and error. Single-speed cranks can be used for mountain bikes, road bikes, BMX bikes and folding bikes. The number of teeth on a single-speed crankset can range from 32 to 46. For fixed-gear bikes where the crank can only be moved forward, it is recommended that you purchase a crankset with more teeth.

How much you can expect to spend on a bike crank

Bike cranks cost between $28 and $54.

Bike Crank FAQ

Why change a bicycle crank?

A. If you’ve put more than 5,000 miles on your bike, it’s a good idea to install a new crank. It can make your riding smoother and safer and easier to pedal.

Are shorter bike cranks more comfortable?

A. Unless you are a very tall person, having a shorter crank can make pedaling more comfortable. Changing to a shorter crank means less range of motion. This can put less strain on your hips, knees, and back.
