Been running the dart on the front for years now.Somewhere in the distant past I must have replaced the rear smoke and not been able to get another.Out at Cannock today with my eldest and noticed one of the rear tyre nobs was hanging off and the tube starting to bulge through on the Jones tyre.Careful ride into Swinnerton cycles to replace said tyre, mentioned I'd got a Dart on the front the guy disappears and comes back with a Smoke Classic Oh joy worth every penny, surely one of the best tyre combos you can get
