Having bitten the bullet and replaced my '70s road bike for a '05 LeMond, I was off on my first commute into London (A22/A23). Journey in was fine (getting used to the gears etc), journey home wasn't quite so good. Heavy downpour from Purley was OK, but the flat at the top of the north downs was a pain. Now the question, I've got Bontrager Duel Composite on at the moment and wondered whether I should consider changing them to something more puncture resilient and if so, what. Suggestions please folks.
