Lightweight wheels for all mountain, enduro and E‐Bike. The new MT+MULLET wheel in 30‐millimeter internal rim width is on trend and price point to match big tires and rider preference. With a very light weight, the MT+ MULLET are available to drop heavy duty Bikes weight significantly.

What is Mullet and why?

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

- More agile: A smaller rear wheel allows you to turn faster in order to avoid obstacles or do curves better, it is also much more resistant to the impacts it receives.

- Accelerates faster: If a smaller wheel accelerates faster and on the other hand, a bigger wheel keeps up better inertia. So the mix of the two sizes is perfect.

Everything is better, riding with a 29" front wheel helps you to pass obstacles easier and it pulls you to the fast sections.
27.5 rear wheel make you very agile on difficult trails and capable of accelerating the bike quickly when you need it.

Which makes this combination the best options for riders.

PSG (Perfect Spoke geometry)

Every Progress Wheel is designed for his specific operation purpose. Our choice of rim, hubs, spokes and lacing pattern isn’t just a coincidence.
We strengthen rims at every spoke hole on each rim we develop. The spoke hole and nipple seat is perfectly aligned with hub and spoke angle.
This creates a perfect spoke geometry which allows us to use high spoke tension by an evenly and equal tension distribution. Releasing excessive stress from spokes we get long-lasting and high performance on every wheel.

ORTF (Optimized Rim & Tire fit)

Progress offers a wide range of wheels which are perfectly designed for each riding style. Every rim shape we offer matches with the need of modern tires and their installation.If you follow our rim dimensions you’ll find extra wide tire fit. Wider tires roll better, improve handling and cornering. The appearance is a perfectly integrated tire and more homogeny. Please follow our Tire Width Recommendation.
