When these conversations come I always end up thinking who are all these people who use mtb kit for road riding?
I’m in one road club and familair with lots of riders from another road club and I was until recently in a mtb club.
So I know lots of people for who cycling is a big part of there life.
I dont however know anyone who rides a road bike with anything other than spd sl.
I dont know anyone who wears mtb clothing to ride road.
I dont know anyone who has discs on a summer bike.
I do know lots of people who wear lycra on mtb( try any competitive xc event).
This is all fitness/club/race rides btw if your commuting or going to the pub people will wear whatever.
