As a consequence, it's actually slower-rolling than many mountain knobbies, let alone performance-oriented road slicks.
I currently have brand new unused 2 semi-slik tyres:
Shwalbe Marathon Mondial 2.0
Maxxis Pace 2.1
I have checked slik tyres in local store today, and I was told, that probably there will be no much difference in speed between semi-slik and slik.
The question I have now:
Should I keep my old mountbike Maxxis Larsen TT 2.0 and do my brevet using this tyres or if I put those 2 semi-slik tyres I mentioned above - I will get improvement in speed?
Larsen tyres already used, so protection is kinda weared off and they look like slik tyres somehow. Or new semi-slik tyres is still better then old used mountain bike Larsen TT tyres?
