Mountain bike hubs are a compromise between weight, friction, and durability.

If hubs are built too light, there’s a risk of breaking the internals when you apply sudden bursts of power. And when a rear freehub fails, you become a walker – instead of being a rider.

Only the toughest hubs will do for heavy-duty mountain bikers, like downhill, enduro and e-bike riders. And that’s what Trailmech does.

Helical shaped internals 

The Ukrainian cycling component brand differs from many other hub suppliers.

Instead of designing locally and contracting production to a Chinese or Taiwanese vendor, Trailmech fabricates and assembles its hubs. And it happens in Poltava, which is very much amid the Ukraine war, as the capital city of its similarly named Oblast.

What makes these Trailmech Enduro hubs so good? Instead of pawls and tiny leaf springs, they use a patented Vortex freehub system. Trailtech’s Vortex hub internals use helical shaped lock-in channels, and they work better the more powerful your pedal stroke is – especially beneficial for e-bike riders.

When bigger is better

Beyond the clever helical shaped internals, Trailtech also use bearings three times larger than most other hubs. And oversized bearings are much better at distributing load, making them last longer.

Packing these oversized bearings within the constraints of a mountain bike’s rear axle system is a challenge, but Trailtech’s industrial designers and engineers have solved it with advanced design and manufacturing methods.

Despite the Ukraine war, Trailmech continues to produce its innovative hub systems and has functional distribution through partners in Germany, Italy, Poland, Slovakia, and the Czech Republic.
