Schwalbe Kojak Slick Road Tyre Review:


  • Great grip, no matter what you are riding on, though best suited to smooth concrete and gravely trails
  • Perfect weight to go fast on just about any road
  • Excellent puncture protection from the RaceGuard protection belt
  • As light as a racing tyre, but can be used in all weather conditions


I have to admit I can’t think of any, except maybe that I wish there were a Marathon GreenGuard, too

The tyre will go fantastic in the tight tight twisty trails. The 3.0in tyre still have plenty of cornering authority, but faster riders may prefer the 2.25in version. The wide tyre also gives you better roll over on the inside edge of turns, both on the trails and when at high speed. With roomy sidewalls, you can trust these tyres to take a beating and not be deflated when smashed against rocks or hit with sticks and branches on the trail. The Schwalbe Marathon Green Guard (GS) has great tread, and the ‘shoulder’ of the centre ridge gives great feedback when cornering to keep your trusty bike hugging the trail. The tread pattern is symmetrical, making it a good choice for front and rear tyres. The Marathon Green Guard is unfaultable when it comes to handling, even with low pressures. The round tyre bead is less prone to rolling damage, so can sustain higher pressures. However, you can still roll this tyre at extremely low pressures, though you will suffer a slight loss of grip.

Performance: (out of 5)
