My local bike workshop owner relates:
“I always remind customers to take it easy for the first 50 miles or so - to scrub the tyres in”
The odd customer states: “They’ll be scrubbed in by the time I get to the end of the road!”
“Hang on - I’ll just go and get my dustpan and brush............ “
I’m a fan of the Roadtecs, which give me the mileage and grip I want. Road5s are about £50 dearer per pair.
