Our all-new Pacenti trail xc rim only comes in 29" size 

When designing this new range of rims we looked closely at every aspect of modern mountain biking and what's gone before.

We designed these rims to have no rider weight limit, at 415g we have a rim that can take the punishment out on the trail or the demands of the toughest XC racer. 

Key design features

Convex spoke bed: By creating the spoke bed this way and drilling the rim to support it we are able to achieve 65% lower stresses at the spoke nipple.

Moment of inertia: These rims being low profile will reduce the translational moment of inertia in simple terms the flywheel effect. This improves suspension response, acceleration, braking and cornering.

Deep and wide tyre well for easy mounting of tubeless tyres. 

Hookless rim, why hookless you might ask? Pacenti has always had its eyes fixed on the future, as stated in several independent articles in the cycling press: "What the bead hook doesn’t do is to prevent the tyre from blowing off the rim or keep tubeless tyres from burping". The bead lock and tyre construction are actually the main factors, our bead lock is secure and therefore we don't suffer burping even at lower pressures. We predict that bead hooks will all but disappear in the future. 

The material selection

We are using a high quality 6069 T9 alloy for our MTB rim range. Selection is one thing, quality is another. We test all the alloys we use in production to determine their quality. The T9 process improves the strength and durability over T6 it is more expensive. However, the resulting rim easily justifies the extra cost. 

The proof as always is in the riding and our test team have been waxing lyrical about these rims for months. 

The goal was to produce a modern MTB rim that can be both light and durable these rims are not the easiest to build or manufacture however that is exactly why the ride so darn well.

Manufactured in Taiwan, Designed in the USA.
