Description

The Challenge Grifo is a handmade Italian cyclocross folding tyre of professional quality. In combination with a latex inner tube this tyre approximates the quality of a tube, but with the comfort of a clincher!

The feel, flexibility and stability of this tyre feel extremely good. It is the perfect training tyre, which feels just as at home at competitions.

Great all round grip

This tyre is almost perfect for multi surface cyclo cross racing. Good in most conditions and most surfaces bar deep mud. My only gripe, and why I can't give 10/10 is the fact it will not stay on my Stans Alpha rims due to the year drop shaped bead! Fine on every other rim I have tried but the slightest pressure from a dropped curb, cycle cross hurdle or flying remount pops it straight off the rim. My Scwalbe 1 tyres and Clement pdx don't have this issue.

Pros

  • Great grip
  • Multi conditions
  • Multi weather
  • Supple

Cons

  • Will not stay on Stans Alpha rim
  • Not "officially" tubeless

Great choice of tyre for autumn Cx

I tend to really research the hell out of every product I buy. I went through all sorts of forums, took advice and it always pointed to these tyres. Yes they are a few quid more than your next best tyre but to get what you pay for. Silky ride and great grip. I used them with latex tubes and can not fault the ride. Mantel best the opposition by about £5 per tyre. Well packaged and well received. I’ll be getting some Limus’ for the really muddy stuff in November.

Pros

  • Silky feel
  • Fast roling
  • Light
  • Look great

Cons

  • Hard to get on first time

The best tyre for most conditions

The Challenge Grifo open tubular is my choice of tyre for all occasions until the real thick mud arrives and can be run at low pressure when fitted with the challenge latex cx tubes with less chance of pinch punctures they also look cool on the bike

Pros

  • Grip
  • Lookrun at low pressure

Cons

  • Can be hard to fit
  • Have to be clean straight away to keep side walls
