Areas of Use – from MTB to Road & Gravel
Bicycle cranks are made for various disciplines:
- MTB cranks: Robust and often with 1x drivetrains for maximum simplicity and ground clearance off-road.
- Road & gravel cranks: Available as 1x or 2x, with finely graduated gears for long climbs or wide ranges for adventure.
- Spiders & accessories: Vary based on BCD (bolt circle diameter), crank standard, and axle interface. Modularity allows later chainring changes or power meter integration.
- Power meter options: Integrated or upgradeable measurement systems for data-based training.
This way, you’ll find the right solution for every bike and riding style.
Materials – Light, Stiff, Durable
The choice of material influences weight, stiffness, and comfort:
- Aluminum: Durable and attractively priced, ideal for all-rounders.
- Carbon: Ultra-lightweight and stiff, perfect for racers.
- Titanium: The luxury solution – classy, durable, and a mix of low weight and robustness.
Crank Arm Lengths – More Than Just a Detail
The right length is crucial for ergonomics and efficiency. As a general rule:
- Rider height < 170 cm → 165–170 mm
- Rider height 170–185 cm → 170–175 mm
- Rider height > 185 cm → 175–180 mm
Shorter cranks offer more ground clearance and are suitable for technical terrain. Longer cranks deliver more leverage and therefore torque – practical for powerful sprints.
Pay Attention to Compatibility – Crank and Bottom Bracket Must Match
When buying a crank, it’s not enough to just pay attention to material or length: it’s also crucial that your bike features a compatible bottom bracket for the chosen crank. Differences in axle standards (e.g. BSA, BB30, Pressfit, or DUB) determine whether the crank can be fitted without trouble. So if you want to upgrade or modify, check beforehand which bottom bracket standard your frame uses.
Conclusion: The Right Crank Makes All the Difference
Whether mountain bike, road bike, or gravel: The right crank ensures not only better power transfer but also greater comfort and riding fun. At R2BIKE you’ll find a wide selection of bicycle cranks, spiders, and spare parts – from solid aluminum models to high-end carbon cranks with a power meter.
