Do you need anything else?

Do you want to reduce the weight of your E-bike or Heavy duty bike with a lot of travel or do you just like to impress?
These carbon wheels withstand the highest demands for E-bike, Free Ride and/or Enduro.

What is Mullet and why?

Mullet refers to the mixing of wheel sizes on the same bike, front 29" and rear 27.5".
Since the UCI allowed mixing wheels of different sizes on the same bike, many brands have joined this trend.

- More agile: A smaller rear wheel makes it possible to turn faster to better avoid obstacles or take curves, and it is also much more resistant to impacts.

- Accelerates faster: Yes, a smaller wheel accelerates faster, while a larger wheel maintains inertia better. So the mix of the two is perfect.

It's all advantages, having a 29″ front wheel that helps you get over obstacles easier and pulls you through fast sections.
The 27.5″ wheel makes you very agile on difficult trails and you can accelerate the bike quickly when you need it.

This makes this combination the best choice for pilots.

PAL-TECH

With our latest generation 5-axis CNC machines, we guarantee absolute precision in all machining operations.
Thanks to PAL TECH technology, we ensure 100% parallel bearings to offer maximum performance to your wheels.
The Hubs PROGRESS are designed for minimum weight and maximum durability.

PSG (Perfect Spoke geometry)

Each type of wheel has different requirements.
At Progress we design each wheel for its appropriate use.
The choice of spokes, hub design, Rim and centering are not left to chance.
On each Rim PROGRESS we add extra reinforcement material in the spoke area and we specify the seat angle of the nipples in perfect geometry with the spoke angle on the hub. This allows us to work with the optimum tension and get the maximum performance out of each wheel. In addition, we avoid spoke breakage and provide a long-lasting wheel.

ORTF (Optimized Rim & Tire fit)

Each modality needs its specific Rim along with its specific tire.
At PROGRESS we only offer Rims designed specifically for each type of wheel and use.
Only the perfect size, both inside and outside, allows you to install the perfect tire to fit properly on the Rim.
A wide Rim offers more stability and minimizes undercutting. It allows the tire to maintain a larger contact patch making it more stable against lateral forces.
On technical climbs it provides greater traction and on descents it improves cornering.

Tire Width Recommendation

The inner dimension of the Rim is what gives us the width we should choose for our tire.
Here is our recommendation for MTB wheels.
