Press release:

Horizon V2 Carbon Bars

Building on the success of the original Horizon carbon and alloy handlebars, for 2020 we have completely redesigned the entire range.

Building on the success and performance of the original Horizon Carbon bars, one of the strongest and best performing bars on the market. After extensive testing from computer modelling, lab testing and importantly on the bike, the Horizon V2 is ready for the trails.

The V2 is a ground up redesign, all new shape, feel and lay up in both 31.8mm and also introducing an all new 35mm offering (HZN Stems are also available in 35mm).  The new bar profile retains the same angles and rise options but with a unique offset profile. We think 9° backsweep is the most ergonomic angle for your wrists but the trade-off is you lose some reach vs using a bar with a lower degree of backsweep. This new offset design reduces the overall backsweep at the end of the bar as you roll your bar by 10mm. In effect, compared to standard 9° bars, the new Nukeproof Horizon bars will reduce the lost reach significantly putting your bar in the same position as a bar with a lower degree of backsweep whilst retaining the ergonomic angle. To keep it simple all versions of the bar are available in 780mm and 800mm widths.   

When we looked at developing our carbon bar, we were confident that the handlebar we had was already one of the strongest on the market, but we wanted to confirm this with lab data. To do this we tested our existing bar along with our competitor’s handlebars in the lab to see the like for like results. We saw some surprising results as well as gathered the data needed to develop a new carbon bar ensuring that the strength and flex characteristics of our old bar remained, whilst allowing us to develop our new handlebar and improve further on the original design.

After extensive testing we have optimising the layup. The carbon V2 bars retain a designed degree of compliance to help reduce trail fatigue and small bump chatter but have superior strength figures. To ensure safety and longevity we have incorporate a 3k carbon weave at the bar tips and grip surface. This increases strength around grips/ shifter/ brake lever clamping areas as well as areas where they are most likely to impact the ground. The main body utilises high quality UD carbon layup.

3K Carbon- ultra strong where you need it most

A result of the re-design the V2 Horizon Carbon Handlebar overall weight is reduced by approximately 20g lighter than the previous bar (25mm rise, 31.8mm clamp 252g vs 232g).

The finish of the bars is also improved with a graphic revision. To aid set up, all angle markings are in the riders view to dial in the perfect feel for ultimate control. All clamping points feature particle paint to grip to components at the recommended torque settings.

We’re confident in these bars and continue to offer our lifetime warranty on the Horizon Carbon handlebars.

As well as the carbon bar, our ultimate aluminium Horizon alloy bars are also re shaped to offer all the benefits of the carbon bar design. Again, available in 31.8 and now 35mm options and 800mm width. The bar is formed from high quality 7075 alloy and available in 6 colours and updated graphics and finish. Neutron bars are 6061 alloy with the same rise and clamp options as the carbon bars.

Not Just Carbon we have also available the updated Alloy range

Nukeproof Chain Guide

Fully engineered in Belfast the all new Nukeproof Horizon Chain Guide ensures riders chain remains secure on even the roughest trails. Tested at the highest level on Enduro World Series stages through to your local trails these guides are designed to be compatible with both SRAM and Shimano drive trains and fit most frames.

The Guides are available in 3 options:

  • Low direct Mount (SRAM S2 / Shimano E-Type Standard)
  • Top Guide (ISCG 05)
  • Top Guide with Bash (ISCG 05)

The guides machined 6061 aluminium black plates combine with a composite top guide and bash (where applicable) to secure and protect the drivetrain. On models featuring composite bash guards we include both 32t and 36t bash guards to give you the option on the trails.

The composite top guide on all the chain guides is co-moulded with a softer rubber on the inside to vastly reduce noise and increase longevity. The line which is the top of this co-moulded also corresponds with the height your chain should be at inside the guide.

Mounting holes on the guides are securely slotted to clock the guide at exactly the right angle on your bike. Height adjustments are simply made by loosening the M4 bolt and sliding the guide. Stainless steel hardware has been used through out to give maximum strength and keep the guides looking fresh with ultimate protection from the elements.

Nukeproof will also offer a full range of spares to keep the guards running fresh.

Fully compatible with round and oval chain rings from 28t – 36t.

All guides available in 6 horizon colours (Black, Copper, Grey, Red, Blue and Purple)

Nukeproof Horizon bottom bracket & headset range:

Nukeproof have a long history in components. Our headsets have been on 1000’s of bikes for 10+ years now. The new Horizon headsets is a big step change in performance and quality.

The Horizon headset will feature sealed bearings with titanium coated races with stainless steel balls which can handle even the harshest conditions. If you own a Nukeproof headset already then you can simply upgrade the bearings as they are available as part of our upgrade and spares package. We’re confident of their longevity and have chosen to offer a 5-year warranty on the headset bearings*.

Joining the new headsets for 2020 are an all new range of bottom brackets again featuring sealed titanium coated racer bearings.

On sale in February we are offering a number of Bottom bracket types (UK SRP £59.99):

Threaded 68/73mm:                  Shimano HT2, GXP & DUB

Threaded 83mm:                       Shimano HT2 & GXP

Threaded 73mm:                       30mm spindle cranks

Pressfit 89mm/ 92mm:              Shimano HT2, GXP & DUB

The bottom brackets will come with a 2 year warranty*.

Both Headset and Bottom bracket ranges are available in the 6 Horizon colourways of Black, grey, copper, red, blue and purple.


Scientific bit:

The titanium coating is applied using “Physical Vapour Deposition” which means that the material is vaporised in a vacuum environment and then deposited on the bearing races as a composition coating. This process allows the structure, density and stoichiometry of the coating to be controlled allowing the exact attributes in our design brief to be achieved. The coating is 0.000118” thick and has a molecular bond to the bearing races so it won’t wear off or corrode. The bearing is ABEC 5 certified which means that it has passed tests which include ID and OD tolerance’s, roundness of ball, trueness of faces & surfaces as well as noise testing at high RPM making it the perfect bearing for use in a headset.

These bearings have been designed for use in the harshest conditions, are highly inert and do not oxidize (Therefore will not corrode easily).

Ti coated bearings

The Nukeproof test team have put them through various extreme tests so we are 100% confident in their performance. So confident that Nukeproof will back the new Ti headsets with a 5-year warranty and bottom brackets with a 2 year warranty.

In laymen’s terms, they perform well and last for ages- what more do you need?
