“Introducing the HZN Stem”

Nukeproof have a proud tradition in developing premium components for riders. The latest addition to the HORIZON range is no different. Designed and developed by our engineers in Belfast and tested by Enduro World Series winning athletes Sam Hill and Elliott Heap. 

Since launching our HORIZON components have been a favourite with our riders, won numerous media test and also the Enduro World Series title as well as multiple national races and titles. All HORIZON components are designed with riders needs and demands in mind. As with the rest of the range we had a clear brief in what we wanted to achieve. The new stem needed to offer lightweight performance whilst still being super durable and stiff with a quality aesthetic and finish. Precision machined from a billet of aluminium the new stem offers a super wide clamping point to be super secure on the bars and disperse the pressure on the the bars.

Sketches to get the aesthetics prior to CAD modelling 

Rendered design

As with all our HORIZON products, life starts from hand drawn sketch to get the forms we like within the tolerance set by our engineers. This is then fed into our modellers to create the CAD mock up models and test the stem. We also print the design to check fitment and aesthetics in real life and get a good feel for the design. This is a multi stage process and was repeated numerous times until the stem was perfect.

 3D modelling all in house to refine the design and 3D printed to test fitment  

From here we will go through a testing phase with our in house team prior to handing it over to the race team to ensure it proves itself at the highest standard. This process has taken us over a year and numerous models have been refined and improved to provide what we feel is our best stem ever.

The HORIZON stem


The HORIZON stem has a +5mm rise, this can be inverted to be -5mm if desired.

Final HORIZON stem, weighing in at just 129g (35mm)
