Pepi’s Rokkline Tire Noodles

by 5

Pepi’s Tire Noodle is another foam sausage designed to fit betwixt rim and tyre, protecting both from those nasty pinch flats and dings. Due to their colour, which is much more fluorescent than my camera or screen can reproduce, these are probably the most Enduro tyre inserts we’ve seen yet. You also get two for the money. They don’t sell them singly, so you could either put them in both wheels, or just go for the back and eke out longer life.

This is the tenth insert I’ve reviewed for Singletrack. Since trying out Procore in 2015 though, I’ve become a big insert believer. I used to smash so many wheels, and now I don’t. With so many inserted into 2019 though, I am running out of things to say about tyre noodles. While writing this, I definitely, one-hundred percent absolutely did not waste an hour inserting them into famous works of literary fiction and poetry.


When Pyotr came back in with the tyre inserts Ivan Ilyich looked at him distractedly for some time, unable to work out who he was or what he was doing there. Pyotr was embarrassed by the long look. The embarrassment brought Ivan Ilyich to his senses. ‘Yes,” he said, “Tyre inserts… Good. Leave them there.”

Pepi’s Tire Noodles come in two densities and three sizes, to fit any rim/tyre combo or use (if you’re wondering, there’s a chart on their website). These yellow ones are the heavier Rokkline, but Pepi’s also do lighter, red ones named Raceline.

Claimed weight for these large Rokkline Pepi’s Tire Noodles seems to be 88 – 90g, but I weighed one at 132g. Compared to other inserts, it’s light for its size, and unlike most other inserts, it’s wrapped in plastic; all the better for shedding sealant.

Good quality valves

The valves these ship with are nice and long compared to a standard cheapo no-name tubeless valve. Like the ones that ship with CushCore and Rimpact, they have solid bases with cross holes to minimise any airflow blockages. Weight: 12g per valve.

Quite easy to fit

The wheels and tyres I used these with were 35mm internal width Sun Ringle Düroc Pros, running 2.6in wide WTB tyres – which are not the easiest beads to mount. I was glad of the extra space though, and the noodles went in without much drama. A little bit of stretching and bead stuffing, but that’s it.

At first, the insert was squashing down hard enough on the valve to block airflow. After a little jiggling though, it went up quickly like any other tubeless tyre.

The only insert comparable in size is Vittoria’s Air Liner, and Pepe’s Noodles feel a little softer than that, which makes sense given the comparison of weights – 132g for this, compared to a measured weight of 246g for an Air Liner of similar girth. Albeit, that size air liner is meant for plus tyres.

As I’d expect for such a lightweight but large bit of foam, giving the tyre a squeeze revealed that Pepi’s Noodle compresses quite a lot under air pressure. It was still wide enough to cover the sides of the rim though, and snug enough it wasn’t rattling around inside the tyre.

Why do you ask for registration to view some articles?

We get asked this a lot. The simple reason is that content is increasingly expensive to commission, create and publish and where once the cost of this process was mostly covered by advertising revenues, now that’s no longer the case. We increasingly rely on our paying members to keep Singletrack going and we’d love you to become one of our supporters. however, that’s not we are asking right now. You can read the rest of this feature simply by registering an account on our site.

How does being a free, registered user help you?

It’s NOT so we can sell your email details. It’s not so we can show you more ads either – in fact when you register we show you fewer ads. The reason is actually because registered users come back and look at more of our content. They start interacting with us and posting comments of their own and joining in forum discussion. That level of interaction is what eventually feeds our new subscriber numbers and so for us the journey to gaining new subscribers is to start by encouraging you to simply register an account. We hope that the benefits that will bring to you will be the first step in you joining us as a Singletrack Premier supporter.

David Hayward

Singletrack Contributor

David started mountain biking in the 90’s, by which he means “Ineptly jumping a Saracen Kili Racer off anything available in a nearby industrial estate”. After growing up and living in some extremely flat places, David moved to Yorkshire specifically for the mountain biking. This felt like a horrible mistake at first, because the hills are so steep, but you get used to them pretty quickly.

Previously, David trifled with road and BMX, but mountain bikes always won. He’s most at peace battering down a rough trail, quietly fixing everything that does to a bike, or trying to figure out if that one click of compression damping has made things marginally better or worse. The inept jumping continues to this day.

    These look good.

    I have now put a snakebite in 5, yes, 5, rear tubeless tires in the last 2 yrs, had a credit voucher for alltricks and they had them in stock. Job jobbed.

    Once I get them in and use for a bit I’ll stick a review in the forum.

    These things are looking more like Moto-Cross mousses every second.

    Are we getting to the point of airless tyres? Seems like we’re most of the way there with noodles like this, so I’d love it if we could go the whole hog and never have to worry about punctures again…

    The more I read of these the more I’m thinking that Keithr has it on the nose. What is the weight penalty of going the whole hog and just having a solid (but still squishy) foam tyre?

    I should add that I’m well aware that airless bike tires do already exist – but they seem mainly to be in the road-riding discipline. I’m looking forward to them becoming the norm for off-road riding.
