Kyiv 40mm road Wheels

(1 customer review)


The first wheelset we ever built, our Kyiv wheels are remarkably strong and speedy. They only differ from the Dnipros thanks to their slightly narrower rim, although this still pairs perfectly with 28mm tyres.


This wheelset is designed for riding, racing, or bike-packing on 25/28/30mm tyres. Practically, this means that it needs to be light, aerodynamic, but most importantly strong enough to withstand the rigours of racing on a variety of surfaces.

The strength of these wheels is assured by 28 Sapim CX Ray spokes, strengthened rims, and tough gravel 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. Our Kyiv wheels are our first ever wheelset, so it was natural we would name them after Ukraine’s capital city.


Our rims are made from a high quality T800 carbon fibre, for compliance, stiffness, lightness, and strength. With a 27mm external width, 22mm internal width (below rim hooks) and an 18.35mm width between rim hooks, these wheels are most aerodynamic with 25 and 28mm tyres, but can accommodate anything up to 43mm.

A U-shaped rim profile provides maximum aerodynamic efficiency at a wider variety of yaw-angles than a standard V-shaped rim. Our rims are paired with bladed Sapim CX-Ray spokes for their legendary strength, longevity, and aerodynamic advantages.


Our Ukrainian Trailmech hubs are some of the finest gravel hubs on the market, and with their patented Vortex ratchet engagement system power transfer is almost instant offering between 6 and 7.2 degrees of travel. It’s not only quick, but also strong – the unique vortex design means that the more force you put through the pedals, the harder the ratchet engages reducing the risk of slippage.

As with all ratchet hubs, the sound of the freewheel is a distinctive mark of quality so be prepared to get used to that ‘angry bee’ sound, and wonder how you lived without it before. Note: if you’re not a fan of a loud freewheel, adding a little more 5w-40 oil to the ratchet will reduce the volume.

Inside these beautiful CNC alloy hubs, you’ll find high-quality Japanese EZO bearings for high efficiency and low maintenance.


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.

  1. Jonny

    I bought these wheels specifically to withstand the rigours of ultra cycling events where reliability is paramount. In several months of riding they have lived up to my expectations. I also configured these to run tubeless tyres and fitting each tyre effortlessly took only a few minutes using normal hand-levers which may prove crucial when faced with a puncture in a remote location.

    So far the ride has been incredible and they have performed well in all conditions including high winds and rain.

    The pre-sales support was excellent and helped with choice of additional components that I required for the tubeless setup.

    Finally the wheels look fantastic and I look forward to using them on many adventures.
