Mountain bike crankset chainring compatibility

5 min read

Asked by: Cody Amundson

A replacement chainring has to have the same BCD as the crankset, as well as the same positioning of the bolts, so the two join up. The BCD of any given crankset also sets the lower teeth limit for chainring compatibility. If you have a 130mm BCD crankset, for example, the smallest compatible chainring is a 38t.

How do you know if chainring is compatible?

One of the easiest ways to determine which chainring is going to be compatible with your crank is to simply type in your brand, type, groupset, and type, added with “chainring”, and possible the amount of teeth you want. You can find the type of the crank located at the back of it.

Are all mountain bike cranksets universal?

Many chainrings are not compatible across different brands or even across different models for any given brand. Cranksets attach to a frame via bottom bracket, and there are many different types of bottom brackets.

How do I know what size chainring I need for my mountain bike?

Broadly speaking, if you ride a 29er and/or ride in steep mountains go for a chainring with 32T or fewer (the 11 speed Sram XX system goes down to 28T if your bike has the XX drivetrain). If you ride 26″ or 27.5″ wheels and/or ride in less mountainous terrain then go for a 34T or possibly even 36T chainring.

Can I put a bigger chainring on my MTB?

Yes, you can put a bigger chainring on your Mtb.

Does any chainring fit any crank?

You can replace the chainrings on your crankset, but not all chainrings will fit all cranks. First, different cranksets may have a different number of arms or direct-mount interfaces (connecting the cranks to the chainrings), and they may be positioned differently.

How do you buy the right chainring?

Do you like spinning your legs in faster rotation or more of a slower and harder push? If you like spinning quick then smaller chainring will get you spinning the cranks like you want. But if you like pushing the big gears, go for a larger chainring. Also consider your fitness level when combined with the terrain.

Are SRAM and Shimano cranksets interchangeable?

Thus, cranks from Shimano, SRAM, and Campagnolo are freely interchangeable along with those from all aftermarket brands (e.g. FSA, Rotor, Praxis, etc.). And while it is preferable to match the chainrings/crankset to the transmission, there is no strict need to do so.

Can I replace chainring without removing crank?

Changing rings is not that difficult, and in some cases, it’s possible to replace chainrings without removing the crank. That possibility is limited by what ring sizes you’re using, but hey, it’s always nice when you can work smarter not harder. This trick works for most road cranks and some mountain cranks.

Are Shimano MTB cranks interchangeable?

Shimano road cranks are interchangeable between other component levels that utilize the dual pinch bolt. Nearly all pinch-bolt style Shimano road cranks are able to be interchanged in equivalent lengths.

Is a bigger chainring faster?

Bigger chainrings and cassette cogs run more efficiently than smaller ones but extreme cross-chaining can cancel out those efficiency gains.

How do I choose chainring size?

The larger chainring gives you bigger, harder to turn gears that move you further per pedal revolution – so it’s suitable for higher speeds – while the smaller chainring gives you gears that are easier to turn but move you a shorter distance per pedal revolution – so it’s suitable for lower speeds, including riding

What gear ratio is best for MTB?

Here’s the short answer: The best mountain bike gear ratio for climbing is 46 to 49 on a chainring and 16 to 18 on a cassette. For more diverse rides, mountain bike gears of ratios 46/17 to 42/17 are what work for flatter terrain or occasional hills.

Can I use a Shimano chain on a SRAM chainring?

Shimano and SRAM 11-speed chains are cross-compatible. If you have a Shimano 11-speed drivetrain, a SRAM chain will work fine and vice versa, however manufacturer’s recommend pairing your components for optimal performance.

Are all chainrings the same size?

Rings are supplied with different sizes with different amounts of teeth. The more teeth, the bigger the chainring. The number of teeth affects how much effort is needed to turn the pedals. The larger the chainring the more rotations of the rear wheel you’ll achieve by a single rotation on the front chainring.

Can I use an 11 speed crank on a 8 speed bike?

How do I know the size of my chainring?

Quote from video: And you could go around it just count the number of teeth on the chainring. And that's real easy or often the chain rings will have a number stamped on theirs this is 53.

How do you match chainring and cassette?

In general, cassettes, chains and chainrings are compatible with each other across manufacturers. You just have to make sure you select a chain and chainrings that are compatible with the number of sprockets in the cassette. The number of rings on the crank does not matter.

What type of chainring do I have?

The two main determinants on which size of chainrings you can use is the spider type and Bolt Circle Diameter (BCD). Cranks have either four or five bolt chainring attachment know as the spider. You can’t run 5-bolt chainrings on 4-bolt cranks and vice versa. Newer chainsets are 4 bolt while everything else is 5 bolt.

How do I choose a bike chainring?

Quote from video: And this area here where the chainrings Glide is smaller in diameter. Now these chain sets generally come with a 52 big chain ring combined with 34 or a 52 tooth big chain ring combined with 36.

Is a bigger chainring faster?

Bigger chainrings and cassette cogs run more efficiently than smaller ones but extreme cross-chaining can cancel out those efficiency gains.

What is the best chainring combination?

Standard Setup. Currently, the most common gearing setup on new road bikes is a 50/34 chainset with an 11-28 cassette. This means that the big and small chainring have 50 and 34 teeth, respectively, and the cassette’s smallest cog has 11 teeth and its largest cog has 28 teeth.
