Bike Cranks

(35 products)

A crankset is a core drivetrain component that transfers power from the rider’s legs to the chain and rear wheel. Choosing the correct crankset depends on your riding style, gearing preference and compatibility with your bottom bracket and drivetrain system.

Our range includes road cranksets, MTB cranksets and advanced power meter cranksets from leading brands.

Compare crank length, chainring configuration and axle standard to find the right option for your bike.

Power Meter Cranksets

A power meter crankset is a performance-focused upgrade that measures how much force you apply through each pedal stroke. This allows riders to track wattage output and train with precision.

Unlike heart and cadence, Power tells how much you're actually working not just how it feels.

They are commonly used to:

Train within specific power zones (endurance, threshold, VO2 max)
Pace efforts during races and long rides
Measure performance using FTP (Functional Threshold Power)

Types of Power Meter Cranksets

Single-sided power meters. Measure power from one leg and estimate total output. More affordable and lightweight.
Dual-sided power meters. Measure power independently from both legs for greater accuracy and insight. Ideal for advanced riders.

When choosing a power crankset, consider crank length, drivetrain compatibility and your bottom bracket type.

MTB Cranksets

MTB cranksets are designed to handle rough terrain, technical climbs and off-road riding conditions. They prioritise durability, chain retention and stability.

Key Features of MTB Cranksets

Durability. Built from aluminium or carbon to withstand impacts, mud and trail riding.
1x Drivetrain Systems. Most modern mountain bikes use a single chainring for simplicity and reliability.
Crank Arm Length. Typically ranges from 165 mm to 175 mm.Shorter arms improve clearance on technical terrain.Longer arms provide more leverage.
Boost vs Non-Boost Compatibility. MTB cranksets are designed for different rear hub spacing:Boost (148 mm)Non-Boost (135/142 mm)
Chainline and Q-Factor. Wider Q-factor improves stability and accommodates larger tyres.

Types of MTB Cranksets

1x Cranksets (Single Chainring)

Most common on modern MTB bikes.
Simpler, lighter and more reliable.
Works with wide-range bike cassettes (e.g. 10–51T).

2x Cranksets (Double Chainring)

Offers a wider gear range.
Suitable for mixed terrain and touring.
Requires a front derailleur.

3x Cranksets (Triple Chainring)

Found on older or entry-level bikes.
Provides maximum gear range.
More complex and less common on modern bikes.

Crankset Compatibility Explained

Choosing the correct crankset requires matching several key components.

Bottom Bracket Compatibility

Cranksets are designed to work with specific bottom bracket standards, including:

BSA (threaded)
PressFit
DUB

Always ensure your crankset matches your frame’s bottom bracket.

Chainring Compatibility

Cranksets use different mounting systems, including:

Direct mount
4-bolt spider
104 BCD

This determines which chainrings can be fitted or upgraded.

Bike Crankset FAQs

What crank length should I choose?

Most riders use crank lengths between 155mm and 175mm.

For mountain biking, more and more riders are choosing shorter cranks. To the point where 155mm cranks are becoming popular.

Even for road riding, riders are choosing shorter cranks. These deliver better sustained power rather than high peak power.

Are bike cranksets universal?

No. Cranksets must match your bottom bracket type, drivetrain and chainring mounting standard.

What is the difference between 1x and 2x cranksets?

A 1x crankset uses a single chainring for simplicity and reliability.

A 2x crankset uses two chainrings to provide a wider gear range.

Do I need a new bottom bracket with a crankset?

Not always, but your crankset must be compatible with your bottom bracket.

In some cases, a new bottom bracket may be required.

Can I upgrade my crankset?

Yes. Upgrading your crankset can improve performance, reduce weight or change your gearing setup.

Just ensure compatibility with your drivetrain and frame.
