I have about 25,000kms (if not more) on my current ones, time for a new pair

Roll realy fast on tarmac and excellent grip in all but the wettest of conditions. Have put over 2000 miles on them so far both on a mixture of tarmac, gravel canal towpaths and cross country not had a single puncture to date, although the centre section of the tyre is starting to show some wear on the rear but I am a heavy rider, will swap front and rear soon.

Unacceptable quality on a fairly expensive bike - highly susceptible to punctures even in smooth wet tarmac roads.
