In many ways the choice of rim is the most important part of the wheel.

The latest aerodynamic rims mean faster speeds and increased comfort and handling. 

Our new Aero Pro rims use an improved aerodynamic profile and wider internals in line with recent changes in tyre standards.

Lightweight rims accelerate faster and climb better than heavier models. Bike handling and agility is agility is also improved.

Aerodynamics & rolling resistance

Our rims are aero optimized for today’s wider tyres – increasing speed, comfort and handling.

Nowadays more and more people are choosing to ride wider tyres. 

Our rims are aero optimized for today’s wider tyres – increasing speed, comfort and handling.

Our latest rim profiles smooth airflow in line with NACA principles for aerodynamics. 

Wider tyres mean lower rolling resistance as well as increased comfort. But that’s not all – wider rims mean an improved tyre/rim interface – better airflow from tyre to rim.

And that means they’re faster. 

Climbing & Acceleration

Lighter rims improve acceleration and climbing performance – they also improve the handling and overall agility of the bike

When it comes to saving weight on a set of wheels, the rims are the place to start

This is where you feel the greatest benefit in speed and handling due to the reduced rotational weight. Quite simply, lighter rims spin up faster. Not only do lighter rims improve acceleration and climbing performance – they also improve the handling and overall agility of the bike.

And lighter rims bring your bike to life!

Tyre Information

Our rims are suitable for both tubeless tyres and clincher tyres with inner tubes 

Although they’re aero optimised for 25 and 28mm tyres you can happily go wider – all the way up to 45mm!

Wheels are provided with rim tape pre-installed. Rim tape is suitable for use with tubeless tyres or inner tubes – whichever you prefer.

GXR 21 hubs

Lightweight straight pull hubs – ratchet drive

  • Ratchet Drive hub system
  • 36T ratchet
  • 10 degree engagement
  • Lightweight

Our latest ratchet drive straight pull hubs are smooth, light and responsive. 

The 2:1 lacing pattern at the rear equalises tension and increases lateral stiffness

The 36T ratchet drive provides a rapid engagement angle of just 10 degrees

And that means faster pick-up for climbing efforts, acceleration and sprints!

Lightweight, bladed spokes

Pillar PSR-XTRA triple butted, bladed spokes

 

Pillar PSR-XTRA triple butted, bladed spokes

All of our wheels are hand built here in the UK. For this model we have chosen to use the excellent Pillar PSR X-TRA – a lightweight, triple butted, bladed spoke – reinforced for extra strength and durability right where it matters.

What's included?

  • Quick Release
  • Brake Pads
  • Tubeless Rim Tape

Wheels are provided with rim tape pre-installed. Rim tape is suitable for use with tubeless tyres or inner tubes – whichever you prefer.
