Cranks

(34 products)

A crankset (or bike crank) is a key component of the drivetrain. It transfers power from the rider's legs to the bike’s chain and rear wheel.

Choosing the right crankset can make a noticeable difference in efficiency.

Our collection includes a range of options for different riding styles.

Choose from lightweight road cranksets, durable MTB cranksets and advanced power cranksets. Power cranks have built-in power meters that help you train smarter.

Power Crankset

A power crankset is a performance upgrade with a built-in power meter.

Power meters measure how much force a rider is applying during each pedal stroke.

These cranksets track wattage output, assess training load and optimise performance over time.

Power cranksets deliver data like cadence, torque and left/right leg balance.

They are compatible bike computers and apps.

Their purpose is to:

  • Help you train specific power zones (e.g. endurance, threshold, VO2 max...).
  • Help you pace for racing and long events to stop you burning out.
  • Help riders assess pedaling efficiency and correct left/right leg imbalances.
  • Set a clear benchmark of their abilities using FTP. Functional Threshold Power (FTP) is the maximum average power a rider can sustain for an hour.

There are two main types of power cranksets:

  • Single-sided power cranksets. Measure power from one leg (usually the left) and estimate total output. These are more affordable and lightweight.
  • Dual-sided power cranksets. Measure power independently from both legs for greater accuracy and insight. Ideal for advanced riders or those recovering from injury.

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

MTB Crankset

A MTB crankset is a critical part of the drivetrain.

It's designed to handle off-road terrain, rough trails, and technical climbs.

Key Features of MTB Cranksets:

Durability. Built from aluminium or carbon to withstand rock strikes, mud and impacts.

Chainring. Modern mountain bikes use a 1x (1 chainring) setup for simplicity.

Older or more traditional set-ups may use 2x or 3x configurations for a wider gear range.

Crank Arm Length. Most MTB crank arms range from 165 mm to 175 mm.

Shorter arms are often preferred for technical terrain or smaller riders.

Boost vs Non-Boost. The spacing of your bike’s rear hub affects the chainline.

MTB cranksets come in Boost (148 mm rear spacing) or Non-Boost (135/142 mm) options.

Chainline and Q-Factor. MTB cranksets are designed with a wider Q-factor to accommodate larger tyres.

Plus with your feet slightly further apart, there's more stability on rough trails.

Types of MTB Cranksets

1x Cranksets (single chainring):

  • Most popular for modern MTB.
  • Simpler, lighter, and less prone to dropping chains.
  • Often used with wide-range cassettes (e.g., 10–51T).

2x Cranksets (double chainring):

  • Offers more gears, useful for mixed terrain or touring.
  • Slightly heavier and requires a front derailleur.

3x Cranksets (triple chainring):

  • Rare on newer bikes but still used on budget or older models.
  • Offers the widest range but more complexity.

MTB Crankset Compatibility

Bottom Bracket Type.

MTB cranksets are designed to fit specific bottom bracket standards.

BSA threaded, PressFit and DUB are some common ones.

Always check your frame’s bottom bracket compatibility before buying.

Chainring Mount Style.

Common interfaces include Direct Mount, 4-bolt, and 104 BCD.

Direct mount systems allow easy swapping of chainrings without spider removal.

Brand Matching.

Choose components from the same brand. This to ensure smooth shifting and drivetrain performance.
