Huck Norris has expanded their featuring of mountain bicycle tire inserts, introducing the Toast, Sandwich and Hamburger. Tailored for XC, Enduro and Downhill, respectively, these rim-preserving, puncture-protecting against inserts differ in their body weight and density, in accordance with the demands of each self-control.
Even though the lighter body weight Toast is composed of a one density shut-cell foam, the Sandwich and Hamburger tire inserts are dual-density, incorporating a little bit of development to tire-rim bottom-out eventualities and enhancing rim protection. We bought the Mega Norris Sandwich tire insert in for screening here’s how it fared on the Enduro trails of the Tweed Valley.
MegaNorris Sandwich Tire Insert
There are two variations of the MegaNorris Sandwich a 55mm (54mm actual) width possibility developed for 28-34mm internal width rims, and a 60mm width alternative made for 33-40mm inner width rims. I opted to operate the insert on the rear wheel of my Revel Rail, a 165mm travel enduro bike with 27.5″ wheels. The wheel in query was a Nukeproof Horizon V2 with 30mm inner width alloy rim.
Admittedly, I did not search at any recommendations right before trying to match the MegaNorris. I was in autopilot method that working day, and proceeded in an attempt to healthy the insert the identical way as other tire inserts I experienced come across beforehand. A lethal error was made when I calculated it towards its meant rim, slicing it down to size using the rim diameter as a marker. Lots of alternative words were uttered while I struggled to put in it with a 2.3″ Maxxis Minion DHRII DoubleDown tire.
Had I glanced at the again of the packaging I would’ve uncovered recommendations on how to slice the insert down for a 27.5″ wheel. Mainly, you need to slash it this kind of that it is a truthful bit much larger than the diameter of the rim, so that it can sit about fifty percent way between the rim and the tire, suspended among the two, and held in position by the pressure it exerts in opposition to the tire sidewalls. There are pre-minimize markers on just about every insert a person for a 27.5″ wheel and a different for a 26″ wheel. They are not labelled as this kind of, but it is pretty evident which slice pertains to which wheel sizing.
With the Sandwich tire insert reduce to its acceptable size, the endeavor of installation isn’t all that arduous. It is a fair little bit additional complicated than an insert-totally free tubeless set up, but very little a strong pair of fingers cannot manage. With the tire equipped to 1 aspect of the rim, the insert is slipped into the volume of the tire right before the second tire bead is teased on to the opposite rim. Our tire did appear a small wonky after set up, with the insert not sat entirely straight within the tire, but that arrived superior immediately after one particular very shorter ride.
Cut to size, the MegaNorris Sandwich weighs 196g, relatively middle of the highway for a tire insert rated for path and enduro using. It’s a good 50g lighter than a CushCore Professional or a RockStop insert, but around 40g heavier than a Rimpact Pro or a Nukeproof ARD. Yet another lighter selection is the Vittoria Airliner at 165g.
At its widest stage the insert is 54mm throughout, therefore, on the Horizon V2 rim which has an outer width of 35mm, all over 4.5mm of insert is overhanging the rim on just about every aspect. Although it is broader than most solitary-density tire inserts, it is considerably, much thinner at just 14mm thick.
Initially, I had two worries with the design of the MegaNorris tire inserts:
- The insert would rattle within the tire
- It would be as well slender to reduce pinch punctures at reduced pressures
I’m happy to report that neither of these problems had been realised.
Even with the truth that the insert is designed to sit suspended involving the tire and rim, I was not equipped to discern any rattling from the insert transferring about within the tire whilst driving along, which is more than I can say for the Nukeproof ARD or RockStop alternatives.
In the course of the month or so that the MegaNorris Sandwich insert was in support I remained puncture absolutely free, regardless of several bottom-out occasions with their linked thud. I did experiment with tire force, varying it amongst 17-22 PSI, and am pleased to generate that I hardly ever felt any discernable tire roll by fast, very well-supported turns, even whilst at the reduce end of that selection. The rim, as well, is in superior fettle, acquiring not experienced any problems throughout tests.
I’m delighted to propose the MegaNorris Sandwich tire insert, with it possessing provided me no rationale in any respect not to do so. It is undeniably one of the a lot more highly-priced selections out there, on the other hand the 55mm version reviewed right here retails at $64.99 USD for a one insert. It isn’t the most high-priced option for rim defense you can fork out up to $149.99 USD for a pair of CushCore Pro inserts and reap the vibration damping benefits. On the worth conclusion of the spectrum, you can pay $51.99 USD for a pair of Nukeproof ARD inserts, if you are delighted to reside with their rattle, which I am (they are lighter, also). Swings and roundabouts, as ever!
