165mm Rotor crank arm. Rotor is a specialist of 165mm cranksets and this length is available for 100% of the manufactured cranks. With the modular system, Vegast and Aldhu are one of the cheapest solutions if you need a 165mm crankset

Introduction to 165mm Cranksets on Velo-Perso.com

165mm cranksets provide an ideal solution for many cyclists seeking both performance and comfort while improving their position on the bike. At Velo-Perso.com, we understand that every detail counts, which is why we highlight the advantages of 165mm cranks for optimized pedaling.

Better Cadence and Pedaling Efficiency

Riding with 165mm cranks optimizes cadence, allowing you to maintain a higher pedaling rate and fully leverage 12-speed transmissions that offer a wide range of small gear options. These cranks promote smoother pedaling, reducing muscle fatigue and enabling cyclists to stay efficient for longer. It’s important to note that switching from 170mm to 165mm cranks can reduce torque, making it harder to power through force alone, thus requiring a greater focus on cadence for effective riding.

Less Knee Stress

165mm cranks limit movement range and reduce joint load, offering better comfort and preventing pain. This makes them an excellent choice for cyclists with joint sensitivities or those engaging in long rides. When paired with Rotor oval chainrings, these cranks help reduce the dead spot and place less stress on the knees at specific pedaling angles, enhancing the overall cycling experience.

Optimized Aerodynamic Positioning

165mm cranks allow for a lower and more aerodynamic position on the bike, which is essential for time trialists and triathletes. By reducing the angle between the torso and thigh, these cranks facilitate a more aggressive and efficient position without compromising comfort. This helps maximize performance in fast-paced courses and competitions.

Reduced Risk of Contact with Obstacles

For cyclocross and gravel riders, shorter cranks increase ground clearance and reduce the risk of striking obstacles during tight turns or technical terrain. 165mm cranks provide this added safety, minimizing the chance of contact with the ground, especially during quick accelerations after corners.

We have selected several 165mm crankset models to meet your needs. Choose according to your budget, weight and stiffness goals, and the necessity for an integrated power meter. If you are unsure, the Vegast cranksets are an affordable option. You can start with a 165mm crankset and later switch to 170mm cranks by changing only the arms (at a cost of around 100 euros). This is the strength of the modular Rotor crankset range.

At Velo-Perso, we offer a range of 165mm cranksets that cater to cyclists looking to optimize their performance and comfort. Explore our selection and find the model that best suits your needs.

Frequently Asked Questions (FAQ)

How can I check if my 165 mm crankset is compatible with my frame?

If you already have a 165 mm crankset, ensure that your bottom bracket matches the diameter and axle length of your crankset. At Velo-Perso, our selection of bottom brackets ensures compatibility with Shimano, SRAM, or Rotor setups. If you don't yet have a 165 mm crankset, you have two options: aim for performance with a Rotor 30 mm crankset and a compatible 30 mm bottom bracket, or keep your Shimano 24 mm bottom bracket and choose one of our 24 mm cranksets, like the Vegast 24 or Aldhu 24.

If I don't like the 165 mm, can I switch back to 170 mm?

Yes, it’s possible. If you have a complete Shimano or SRAM crankset, you’ll need to replace the entire crankset. With a modular Rotor crankset (Vegast, Aldhu, Aldhu Carbon), you can simply replace the crank arms with 170 mm models. Make sure the axle diameter matches: 24 mm crank arms must be replaced with 24 mm arms, and the same applies to 30 mm.

How do I maintain Rotor 165 mm crank arms?

Rotor 165 mm crank arms are very robust. The bolts can be replaced if needed, but if you use a torque wrench set to 35-40 Nm and follow proper installation practices, the bolts should last for many years.

Is the weight of 165 mm crank arms reduced?

Yes, shorter crank arms typically use less material. On average, you save about 10 grams per pair of 165 mm crank arms compared to 170 mm. However, for Aldhu Carbon models, the weight difference is often negligible.

What are the benefits of 165 mm crank arms?

165 mm crank arms optimize cadence, reduce muscle fatigue and knee stress, and allow for an ideal aerodynamic position. They are particularly suited for long rides, triathlons, and time trials.

Are 165 mm cranksets compatible with all bikes?

Yes, just stay focused on the bottom bracket and check that your BB is compatible with your 165mm crankset

Are 165 mm crank arms suitable for triathlon or time trials?

Absolutely. They allow for a more aerodynamic position by reducing the angle between your torso and thighs, improving performance on fast courses.

Are 165 mm crank arms suitable for gravel or cyclocross?

Yes, they increase ground clearance and reduce the risk of hitting obstacles, which is especially useful on technical terrain.

What is the price range of 165 mm cranksets?

Prices range from €350 to €800, depending on the model and options (with or without a power meter).

Why choose shorter crank arms instead of 170 mm?

Shorter crank arms improve cadence, reduce knee stress, and make better use of modern drivetrains, especially 12-speed systems.
