All-new HUNT Trail Wide and Enduro Wide Wheels 1

A new generation of wheels for the latest demands of trail riding and enduro racing.

All-new HUNT Trail Wide and Enduro Wide Wheels

Lab Developed. Race Proven.

Why?

After almost three years of valiant service on local trails and EWS stages alike, with numerous awards and recognitions along the way, the restless design team at HUNT saw an opportunity to update the Trail and Enduro Wide wheelsets to meet the evolving demands of today’s riders.

By listening to customers and sponsored athletes, we set out with a clear understanding of the task ahead. Knowing front and rear wheels perform very different roles, we initially focused on the rear rim development of the Enduro wide. After a detailed review of rider feedback, we identified the potential benefit of creating a slightly narrower rear rim. With this change, the rider benefits from an improved tyre profile with 2.3-2.5" tires, as well as additional rim protection and the opportunity to redistribute the saved weight to further strengthening the profile.

Our vision was to improve the strength-to-weight ratio of the rim through rim profile optimization using new in-house testing equipment designed specifically for this project. The data gathered in our lab established the benchmarking for the damage analysis stage of the project, using two key criteria.

  • First damage energy - The amount of impact energy resulting in visible damage (dent) to the hook.
  • Failure damage energy - The amount of impact energy resulting in ride-ending rim damage.

The rim profile changes, when combined with new hubs and spoke configurations, resulted in all-new HUNT Trail Wide and Enduro Wide wheelsets that offer the rider similar system weights, but with significant improvements in impact resistance to denting.

Development Processes

Impact Testing

We recognized that the UCI impact tests, although key for ensuring safety standards, are not fully representative of the real-world impact performance of rims, which is of real benefit for riders when choosing a product. Our in-house testing equipment and protocol fills that gap and provides riders with the data they need to make the best decision for their riding.

Impacts experienced while riding are not often delivered uniformly or spread over the rim equally. In real-world riding conditions, rock strikes and impact forces are often transferred through a single side, at random incidence angles. To replicate these variables, the wheel is mounted at an angle in our lab equipment and impacted by a round-edged impactor on a single side of the rim (during development we tested a number of shapes to determine the most suitable).

The protocol for the test results described here ensures the isolation of rim profile performance data only, by controlling other variables such as tire, pressure, hub, and spokes used. The graph reflects two results for each rim; first the impact energy at which the initial equivalent sign of an impact is seen in the form of a visual ding, and the second being the energy at which a comparable ding would likely render a wheel unrideable.

*As impact energy levels increased, the damage was not isolated to rim dings but also compromised the integrity of the wheel with spoke de-tensioning and loss of trueness. For all wheels reaching160J, the damage to the overall wheel system was severe enough that as riders and engineers, our experience told us that these wheels would require mechanical attention beyond that of a ‘normal’ trailside repair.

FEA (Finite Element Analysis)

FEA is a numerical modeling method to visualize and analyze the structural behavior of components. When applied to rims, this enables us to perform simulations on the proposed profiles and under identical conditions compare stresses and deformations to the original.

We utilized the power of FEA to modify the material thickness distribution throughout the rim, focusing material in the key areas.

As pictured above, the new EW V2 (right) profile reduces the stresses transferred from the hook, to the tire-bed and rim sidewall, which means under the same load/impact the rim experiences less deformation (dinging).

Hunt Enduro Wide V2 Wheels

This is our all-out, hardest-hitting wheelset for your Enduro rig. Designed to take a beating on the most unforgiving trails, the Enduro Wide takes it all in stride.

27.5"/29"/Mullet | 33 Front/31 Rear Int. Width

Using the impact test protocol, the performance of the current Enduro Wide rim was assessed and validated against real-world impact damage. This highlighted some high-stress areas which could be strengthened with profile updates and by adding an internal support structure located to best dissipate energy.

From here initial concepts were sketched, focusing around a reduced 31mm internal width profile with an internal I-beam structure. FEA was utilized to confirm the high-stress areas in the original model and then to iteratively optimize material thickness distribution throughout the rim, focusing material in the key areas.

After seven consecutive design iterations, the final profile lovingly codenamed ‘Project Senduro’, was achieved.

 

One wheelset, One season | Enduro Wide V2

We were lucky to work with a certain young Scot during his breakout 2020 EWS and DH campaigns. He's since moved onto bigger things this season. Good luck!

Hunt Trail Wide V2 Wheels

Photo

The Trail Wide is your go-to wheelset no matter the conditions. Optimized to still take the A-lines on the descents and not hold you back on the climbs.

27.5"/29"/Mullet | 30mm Int. Width

Starting with what we learnt around profile optimization from the burlier Enduro Wide project, we set out to improve upon its lighter sibling the Trail Wide, not an easy task with an Editor’s Choice-winning wheelset. Beyond simply taking the new Senduro rim and scaling it down to 30mm internal, we went back to the impact rig with its competitors.

Applying pinpointed design tweaks highlighted during the impact testing process, we optimized the material distribution for the desired strength-to-weight requirements. This trail-orientated profile produced a rim that visually appears the same as its predecessor, yet provides a 20% improvement in impact resistance.
