Tubeless Ready: Tubeless tyres provide the rider with many benefits: the ability to run lower air pressures, which improves traction; lower rolling resistance when compared to a tube-type tyre; and less chance of flatting since there is no tube. Maxxis Tubeless Ready (TR) tyres provide the benefits of a UST tubeless tyre without the weight penalty. Our TR tyres use a standard casing and require the use of a liquid sealant in order to make them airtight


EXO: An extremely cut-resistant and abrasion-resistant material added to the sidewalls of select mountain tyres. This densely woven fabric is also lightweight and highly flexible, ensuring that the performance of the tyre remains unaffected. Choose EXO Protection for exceptionally rocky, treacherous trails where the chance of sidewall cuts and abrasions is high.

Maxxis HR2 is already a legendary tyre used by enduro and DH pros (though likely not on the 2.3" guise) so I decided to try having had little prior experience with Maxxis. It was easy to install tubeless with sealant on a mavic wheel. Immediately I was a bit disappointed by how low volume and narrow it is, particularly when compared with the 2.35 Magic Mary it replaces. It's not that light either which made me believe it would be a big tyre. I think it's more of a 2.2 than a 2.3. It feels much smaller than the semi-slick Rock Razor 2.35 I have on the rear wheel for comparison. Would I buy it again? Myabe not , mainly due to the low volume, I would probably decide on the 2.4 version or look at another Mary, Butcher or Onza Ibex (though I have no experience with the latter 2. Performance wise I can't say much yet as I only had it for a couple of rides. It seems to roll better than the Marys but I'm less confident on it, it may be the narrow /low volume nature that is affecting my confidence and maybe with time I learn to rely more on it's abilities. That said it didn't let me down so far on any of the fast corners and jumps. Fast and reliable service from Merlin once again.
