Tyre Hack: Boost Your Roost And Get Insta-Famous

by Hannah Dobson 11

Image is everything these days. And really, a mountain bike video without roost just doesn’t cut it anymore. If you want to get sponsors, you need Instagram followers. And to get them, you’re going to need great video and photo content. And to get great video and photo content, you need to be a certified gnarc0re-shredder.

But what if you’re not?

Well, it would appear that Roost Boost™ might just have the solution…

We’d been hearing rumours about a ‘roost boost’ hack for a while, but it wasn’t until Chipps was on holiday (see the Subscriber edition of Issue 118) with an Instagram celebrity late last year that we got chance to check out the secrets of the technique.

Having seen their tyres for ourselves, we noticed something was a little different about the tread. Something unique to the tread and how it had been adapted. After studying some high-resolution photos in the office, we set about creating our own. And that’s the great thing about this hack – you can do it yourself, so even if you’ve not yet landed a tyre sponsor it’s not an issue. And if you have got a tyre sponsor, more importantly, you can stay on brand.

The Science Bit

The science behind it is that, using a siping tool (aka: “side cutters”), you can create highly specialised cuts in your tyres. The specific Roost Boost™ angle of these cuts means that as you lean around a corner, the air between the narrow space in the cuts is compressed, while the open end is not. Following us so far? The difference in pressure between the narrow and open end creates a vortex effect, which sucks up dirt as you roll through the corner, then throws it up into the air once the contact patch leaves the ground. Like magic!

It’s this angled cut that creates the vortex.

We’ve been testing this on some of our videos recently, and the early signs suggest that there is at least a 57% increase in roost, even at bimble-velocities. There’s still some further analysis to be done, but so far we’re impressed, and our Instagram account is already reaping the benefits.

  1. I pity the fool who thinks roost boost is cool.

  2. Your video only shows a 34% increase in Roost, at best.

  3. Pinkbike is reporting that Shimano is going to release a chain device that can change between chainrings. Madness I tell you.

  4. I have been using a special gas mixture (78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide) with tubeless conversions, and totally failing to roost despite being told this is what expert roosters use.

    Thanks for this, I’ll start hacking my tyres right now.

  5. Nice
    but it only works til lunchtime today, right.

  6. I think we are all missing one thing here though, ‘dust’, I think it’s more of a squirt boost at the moment!

  7. please stop this clickbait garbage…

  8. Hey @pitduck you checked your calendar before posting that, right? 🙂

    And considering we are a British website I’ll think you’ll find it’s actually clickbait rubbish.

  9. If I use roost boost on boost will I get turbo boost roost boost?

  10. It wasn’t April 1st where I live when this was published and I immediately cut my tyres up!

    As for getting precious about the language on the site, surely that’s a joke too? /wink

  11. Wish I’d read the post date…. and the comments… Maxxis Minion plus tyre trashed. Roost no better….
