New Nukeproof Horizon Headset And Bottom Bracket

by 7

We told you last week about new pedals and chain guides, now we have more component news from Nukeproof for you. This time, it’s updated Nukeproof Horizon headsets and all new Nukeproof Horizon bottom brackets.

Horizon Headsets

You may well have a Nukeproof headset already as they’ve been appearing on thousands of bikes for over ten years. So what’s new in the Horizon headset? Over to Nukeproof:

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 (see the Nukeproof website for terms and conditions).

You can also upgrade your old headset with the spares kit.

Nukeproof also provides the science bit. Are you ready?

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.

Parts, built to last.

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

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?

5 years! Make sure you pick a colour you like!

Hannah came to Singletrack having decided there must be more to life than meetings. Having worked in policy and project management roles at the Scottish Parliament and in local government, Hannah had organisational skills that SIngletrack needed. She also likes bikes, and likes to write.

Hannah likes all bikes, but especially unusual ones. If it’s a bit odd, or a bit niche, or made of metal, she’s probably going to get excited. If it gets her down some steep stuff, all the better. She’ll give most things a go once, she tries not to say no to anything on a bike, unless she really thinks it’s going to hurt. She’s pretty good with steri-strips.

More than bikes, Hannah likes what bikes do. She thinks that they link people and places; that cycling creates a connection between us and our environment; bikes create communities; deliver freedom; bring joy; and improve fitness. They're environmentally friendly and create friendly environments.

Hannah tries to write about all these things in the hope that others might discover the joy of bikes too.

    ‘noise testing at high RPM making it the perfect bearing for use in a headset’

    Yeah. Because I’ve alway said to myself ‘feck me my headset is noisy at high RPM’ when turning it through about 20 degrees maximum riding down a trail.
    Marketing BS x1000 = I’m oot.

    60 quid for a stainless BB compares pretty well with Hope, not to mention the usual Nukeproof discounting. I could see myself buying a few

    I take it the second line on the top cups should be a zs44 code not ex34 and that’s just a copy paste error?

    Yep, at £60 for a BB, I’ll keep an eye on these, especially as honourablegeorge says, they’re likely to be discounted at some point – should last longer than my XT ones anyway!

    BSA / DUB option is welcome. £10 off £50 with NCV2020 code for ‘new’ customers.

    I’ll certainly be keeping an eye out for the BB when mine needs replacing, although like robertajobb aludes to, it seems a bit extreme to do high RPM testing on a bearing the will at most (and only if you crash a lot) travel 270 degrees in most of it’s lifetime, and even then very slowly.

    Hopefully the Threaded 73mm: 30mm spindle cranks bottom bracket will be a decent alternative to the RaceFace I need for my Next SL cranks
