Schwalbe Kojak 700x35c tyre

The Schwalbe Kojak offers great all-weather cornering prowess and are the fastest big volume slick I’ve ever used. Superior town manners mean they're a real hoot when shod to crossers that do turns on the tarmac. Reflective sidewalls, dynamo tracks and similar detailing are notable by their absence, however, and despite a sympathetic riding style, the race guard protective belt seemed unduly susceptible to thorns, sharps and other roadside debris.

The Kojak is available in a wide variety of sizes from 16x1 through to 26x2; even catering for small-wheeled folders, trailers and tagalongs so shamefully discriminated against when it comes to decent quality, performance orientated rubber. We chose the 700x35, which should fit most crossers, hybrids and sporty tourers. 50 Ends per inch (EPI) is two down from top-flight race tyres so you’d be right to expect something pretty swift while the folding version’s 110-kilo maximum payload will reassure heavier riders/those that lug a load or two.

Ours slipped effortlessly aboard shallow and deep section rims with nominal effort, save for a deft nudge of the tyre lever come the final ten centimetres. Soft, speed grip compounds are designed for speed and tenacity through the concrete jungle and at their 95psi maximum, the first few pedal strokes left me reasoning the big ring was the way to go; riders turning CX drivetrains might feel the call of taller gearing.

Wet manhole covers, last minute swerves around errant pedestrians and opening car doors, never flustered the Kojaks, although a soggy towpath proved a genuinely scary experience-even relieved of 20psi so these aren’t the rubber for riders craving a crafty cut-through. This also marked our first of three flats, a thorn burrowed deep inside the carcass that was easily removed using tweezers; a drop of superglue sealed the casing. Despite periodic brush-overs, glass and similar nasties infiltrated the protective belt twice in the space of fifty miles, leaving me disappointed by their middling dependability. It could have just been the luck of the draw though.

Verdict

Super swift commuter rubber for most machines, although they seem more susceptable to punctures as a result.

I like these, but I consider them a "dry weather only" tyre due to their lack of good puncture protection.

two wheels good; four wheels bad

Just to offer an alternative viewpoint on the durability of these tyres - I only recently binned the Kojaks on my commuter after 3,000 miles riding through central Edinburgh. In all that time I had one flat.

I put these on my Salsa Vaya for a short tour of Wales last week. I'd previously been slightly frustrated by the enormous weight of Schwalbe Marathons, and found the Kojaks to liven up the feel of the bike enormously. Very comfortable and surprisingly fast. I haven't spent enough time on them to offer much of an opinion about durability, but I spent a fair proportion of my week on wet back-roads, cycle paths and tracks with a moderate saddlebag on and didn't have any trouble with flats.

The review left me wondering if you got a pair without the puncture protection belt. My 700x35c Kojaks felt surprisingly sluggish. The casing is far from supple and the ride quite harsh. Also the compound feels more plasticky than rubbery. Trying to fold the tyre inside out reveals the stiff nature of the protection belt. I got no punctures in a couple thousand kms.

In my opinion Marathon Dureme is a much better tyre. It's about 70g heavier but rolls at least as fast as the Kojak. It's more comfortable, versatile and confidence inspiring.
