The Kojak Tire is made exclusively for Brompton by German tire experts, Schwalbe. It's full slick, narrow profile and ultralight Kevlar bead make this the fastest and lightest tire available for a Brompton.
This tire is most at home on city streets for fast commutes but because of its lower profile and foldable Kevlar bead it is great for touring too. Its Reflective sidewalls keep you visible on dark nights and its RaceGuard gives enough puncture protection to keep you out of trouble.
The Kojak should be kept at a higher pressure than the Marathon or Marathon Racer making these lightweight slicks the fastest Brompton tire in the range. When you combine that with the slightly smaller diameter, the gearing ratio is lowered by 2.5% so we recommend pairing these tires with a +8% (54t) gear ratio.

A BIT ABOUT BROMPTON: If you were to walk into the store and look at a Brompton we would say there are three things you should look for in a folding bike. All of them are fairly obvious. One, the bike should ride well - and, on a small wheeled bike that's tricky because there's a fine line between maneuverability (which is a virtue) and twitchiness (which is a vice). Two, the bike should fold well - otherwise you're blood pressure will rise and you'll curse the day you bought it. Third, it should be transportable, or highly storable - because that's the whole point, right?
Brompton is the only company we've seen that answers all three criteria - and believe us, we've tried every brand out there. The reason others can't compete is because Brompton has answered a fundamental engineering problem. If a bike is going to unfold to a large footprint (which takes the twitch out) then it is unfolding to a bigger bike - and by all logic, a bigger bike unfolded would be a bigger bike folded. So, it's pretty much true that for most folding bikes they either have great rideabilty but poor transportability or vice versa. And nearly all of them are a mess to fold.
Not Brompton. Brompton has designed the Platonic form of all folding bikes. The bike folds to the smallest size on the market, unfolds in a highly precise and easy manner, and has the same axle-to-axle footprint as a hybrid bike. How did they do this? By not only designing a clever frame, but also designing some 1200 proprietary parts that make everything fit - and fit perfectly. Oh, and nearly all of this is made in England. No wonder this bike has a cult following.
