The Maxxis High Road HYPR K2 claims to be the brand’s best road race tyre, and features a 170 TPI casing with a K2 Kevlar composite puncture protection layer, which is also claimed to be more effective than Kevlar only or Vectran.
Maxxis says that its all-new HYPR compound rubber tread will lower rolling resistance as well as improve traction in the wet.
My 25mm pair weighed in at 575g, but the non-tubeless version costs £10 less and will save on weight: a claimed 80g per tyre.
I tested the TR tubeless-ready version of this tyre, which, when used on an appropriate rim, along with sealant, offers the benefits of a tubeless tyre but with lower weight. Sounds ideal.
I did find that it was a little tight when fitting, as is to be expected, but it was still flexible enough to wrangle in to place. It seated willingly with a track pump and sealed satisfyingly fast.
On rims with 17mm internal width, the Highroads inflated to 25mm with a fairly tall shape. Most of the tread is slick, with file tread-filled leaf shapes alternating with siped slick sections along the shoulders.
Together it ensures great straight line speed and progressive cornering grip, helped along by the High Road’s supple casing.
These tyres accelerate well from slow speed and they ride with confidence.
