We think in future Brompton riders need to bring at least one inner tube for their bike and to ensure they know how to remove the wheels, inc the rear one obvs, and possess the necessary spanners to get the wheels off. They should not rely on the TEC team knowing the intricacies of Brompton wheels and having the right tools.
The TECs usually don't have a Brompton spanner and have usually never removed a Brompton rear wheel. Riders such as
@AKA Bob are experienced but usually not on the TEC team.
