Design
This wheelset is designed for endurance racing offroad. Practically, this means that it needs to be light, but most importantly strong enough to withstand the rigours of racing on all surfaces.
The strength of these wheels is assured by 32 Sapim CX Ray spokes, strengthened rims, and tough Trailmech boost hubs. These wheels are therefore also suitable for heavier riders looking for fast road wheels.
All of our wheels are named after cities and rivers in Ukraine, out of respect to our Trailmech colleagues and all Ukrainians affected by the conflict. We chose the city of Poltava to name these 29ers after, the city where Trailmech are based.
Ultra-wide Rims
Our rims are made from a high-quality T700/T800 carbon fibre, for compliance and stiffness, lightness and strength. With a 30mm internal width and 25mm depth, these wheels are designed for proper MTB tyres, and can go as large as pretty much any tyre your bike will fit.
The wide rim bed means you can ride wider tyres with better handling, lower ‘squirm’, and reduced risk of pinch flats, whilst also increasing efficiency at lower pressures across a wide range of surfaces.
Our rims are paired with bladed Sapim CX-Ray spokes for their legendary strength, longevity, and aerodynamic advantages.
Hubs
Every Poltava is built on DT Swiss 350 Boost hubs, made in Taiwan, with 15x110mm front and 12x148mm rear thru-axles. It’s the hub more ultra-distance racers trust than any other: DT’s Ratchet system (36 teeth as standard, tool-free upgrade to 54), Centerlock rotor mounts, and spares in almost any bike shop in the world.
Choose SRAM XD, Shimano Micro Spline or Shimano HG when you order. Riding an older non-Boost frame? Email us and we’ll see what we can do. Our original hub partner Trailmech has paused production because of the war in Ukraine; read about our relationship with them and why this wheelset is named after their home city.
Handbuilt
The value of handbuilt wheels is often understated. They can last a lifetime if well-specced and built by an experienced wheel builder. Whilst it’s often thought that wheel building is just about producing wheels that are true (aligned) in all directions, this is far from correct.
The strength of handbuilt wheels really comes from the way the spokes are tensioned and ensuring this tension is uniform throughout. The spokes on our wheel are individually measured to ensure perfect tension and uniformity across the entire structure.
To finish the build, we seat a tubeless tyre on the wheel and then measure the tension again across all spokes. This ensures that there is no shifting or settling of the spokes and rim to worry about when the wheel gets its first use.
Customise Your Wheels
Don’t see the options you want on this page? Don’t worry, we often build to spec and are happy to advise on custom builds. Whether it’s adding a dynamo hub or accommodating an unusual axle combination, we can figure it out.
Drop us an email at hello@zolla.cc and let us know what you’re looking for. Lead times for custom builds vary depending on component availability, but we can usually get them turned around in a few weeks.
Warranty
Our wheels are built to last, with each wheelset individually handbuilt. Therefore, we’re happy to offer a five-year warranty across all our wheels. This covers any material or workmanship failures or flaws. You can read more here.
If you have any problems at all with your wheels or require advice regarding routine maintenance then don’t hesitate to get in touch. You can email us here.
