Huck norris™

Huck Norris’s mission is to eliminate the fear of wheel and tYre damage. We aim to put the mountain bikers mind at ease so that you can concentrate on your riding and not worry that your tYre will get punctured or your carbon rim might get destroyed. Thank science there is a cure! Say hello to Huck Norris.


Huck Norris is undefeated in every way and there are three general scenarios where you need our system:

  • Race: Everything above plus you can save your run by running flat and without destroying your wheel. This is very important in Enduro races where you get penalty if the wheel is replaced.Huck Norris is a an closed cell foam insert which floats inside your tubeless bicycle tire and prevents damage to rims and tires. The shape is developed with professional athletes and experienced mountain bikers. The benefits of HuckNorris are low weight (~80g) and  low friction (~0.3W).
  • Trail or running light tires: You are going for a long ride and want to get rid of excess friction or you want to make up time in competition by using lighter tires. For example in enduro ride you can use around 200g lighter tires with Huck Norris and get better damage resistance.
  • Rocks, roots and riding in harsh conditions: Use Huck Norris to make more damping between the ground and the wheel. This helps you to make the rims last longer and save money.

How does Huck Norris prevent damage

Huck Norris is made from material that has been specially developed with scientists for MTB use. Huck Norris has three times the impact energy damping than anything commercially available from a hardware store.

All Huck Norris products are Made in Finland. Huck Norris tire insert is Patent Pending.

FAQ

Ok, did you guys just make it out of camping mattress?

No, not this version. During past 4 years we have made prototypes from just about all the things that are light and can absorb impacts energy well. Fortunately one of us has material scientist as a neighbour, and through him we got to develop material that is optimised to dampen impacts in force just below what light sidewall protected (read: Exo, Snakeskin, etc.) tyres can survive. So that Huck Norris will absorb as much energy from the impact as it can, and then cells in Huck Norris will break if the impact is hard enough, almost always still saving the tyre and rim. If it would be any harder material you could puncture your tyre before breaking the cells of Huck Norris.
We are looking into making it in more lively colour than this Shady Grey, so that people can start asking whether we made it out of kids beach toys.

WHY?

It’s really simple, if you want more protection from pinch flats in your tubeless setup, you “can” add material to sidewalls of the tyre, but that stiffens the casing and results significantly more rolling resistance. We added the material inside the tyre, so that it has no impact on rolling resistance, and material is exactly where it needs to be to dampen hard impacts to the tyre, making it light, simple and efficient.
We are all racing MTB’s ourselves. We have tried all current commercial solutions available and ghetto tubeless. We were not happy, and this is the best we could come up with. Ghetto tubeless works, but is major pain to install. Other commercial solutions are over engineered, heavy, expensive and require rim modifications or weaken the rim too much.

Will it soak in the sealant?

The material will take 2% of the sealant into itself. In other words; No.
Over time, when cells inside Huck Norris break from hard impacts it takes little bit more sealant, but nothing significant.

Is it directional?

The simple answer is no, fit it what ever direction you want.

How does tire width influence the correct size?

If you run something like 21-24mm rim, you are ok with 2.5” size tyre for the size S, but if you are on the 25mm rim, and on 2.5” tyre, you are risking that Huck Norris won’t be in the right place during impact for the size S and you should choose size M instead. If you are between sizes and in doubt use the bigger size.

What its lifespan?

If you are a regular trail rider you should get a riding season out of your Huck Norris. If you are a rider that likes very rough terrain and races hard you might get a shorter lifespan from your Huck Norris, if this is the case then check for excessive wear and replace if needed.

My Huck Norris makes noise?

Your Huck Norris can move around slightly in the tyre hence the noise. If the noise bothers you, you can shorten the Huck Norris by 2cm’s (about 3/4 inch) so that it fits snuggly against the rim. Shortening the Huck Norris may make it harder to install the tyre.
