Are you just wanting the rubber, or are you wanting them fitted to the wheel? or are you wanting them installed on the bike?
If your just wanting the rubber then see if spanner man can sort you out with a pair of Maxxis Supermaxx Radial had a set on for just over a month now and couldnt be happier hoenstly belive you wont get a better set of tyres for less than £150
Mine were £130 fitted to the wheels.
