Doing the park-and-ride approach today with my Giant FCR wasn't sensible. It's a flat bar road bike, with 52x11 road gearing, and I had the front wheel slide out on wet cobbles
Cue an unceremonious dismount where I managed to get one leg down whilst the other slid sideways when clipped in.
Given I was going the wrong way up a one-way street at the time*, with police at the other end watching, at least I provided them with some entertainment.
* It's one way plus an opposite cycle lane for 90% of the cobbles, then just stops as it directs cyclists over a bridge south-wards. Where else was I supposed to go?
