This morning I changed my singlespeed bike's tyres to more "tarmac" friendly tyres, but still mountain bike derived. They have deep treads, but no knobbly bits. So, this afternoon, I decided to go for a speed run. Immediately the tyres made the bike faster. The pedelling was easier and the rolling resistance was noticably smoother.
So, what time did I do my standard run in? Mmmm...interesting, 1 hour 10 minutes. Less then 5 minutes from my fastest in its 24 geared version. However, that 24 speed time was done on slick 1.5 inch tyres!!!
So now, I'm off to buy another single speed convertion for my other rear wheel, the one with slicks on and I bet I'll beat the geared bikes time next week ;-)
