In the last 3 weeks I've had 4 punctures 2 new rear tyres and both the rears I've had repaired. Last week had the new rear repaired at universal tyres Greenwich[mates run it]then through the Blackwall tunnel picked up a job in Whitechapel going west .Got to Upper Grosvenor st outside the US embassy donk! donk! donk!.Pulled over ,a screw in the middle of the front  tyre must be quite long because the donks I heard was the screw hitting the mudguard .Didn't pull it out, going to need another tyre on the front soon so I'll leave it in .A dear old game going to work, spend more on this bike than I do the wife.I know dispatching your riding on all the dirty parts of the road up the gutters down the outside of the traffic ,but is anyone else finding more more crap your riding over
