As the IG London Nocturne is an indoor race, with a tight and fast circuit I knew that I wanted to finally get and eventually fit something I have coveted since buying a Brompton. Kojak slick tyres.
I have seen Kojaks on lots of Brompton bikes and admired them from afar. They are certainly lightweight.
Kojak 230g Max psi 115
Marathon 420g Max psi 110
Marathon Plus 480g Max psi 95
This of course means that both Kojak tyres are almost the same weight as one of the Marathons. It doesn't stop there. The 115 psi will provide and even sportier feel to proceedings. The slim profile offers less rolling resistance to the extent that gearing is lowered sum 2.5%
They do have a RaceGuard protection strip along the middle of the tyre but one does have to be careful about the surface your ride on. Roads are generally okay but anything rougher and they wouldn't be particularly suited.
Kojak's are tyres I have always wanted to try out but i have not been brave enough, until now. I cannot wait to fit them but the bike that I fit them to is still under debate.
Regular readers will know that I have two Brompton bikes. My beloved Orange Brompton, an M6L and a Raw Lacquer S2L. For the Nocturne in 2012 I opted for the S2L as I felt it was a nipper and sorter ride. Kojak tyres would look stunning on my S2L and take the weight overall down to roughly 10.4kg as apposed to my M6L would be about 1kg more.
I will have to deliberate long and hard about this but if you out there have any suggestions or opinions about which Brompton I should use, please feel free to comment!
