Sat 5th April - London to Brighton 2 (Curse-free)

Ya, I've been trying to figure out what gearing to go with myself. Right now I have 51x19, which I believe is around 71". You guys think that will be okay? Seems like it might be too spinny for a long ride, but then again I keep hearing everybody talk about hills so...

Sorry, I don't really know the route/area so any advice would be appreciated.

you should be fine, depending on how you do in the city

i rode down there last time on 42 x 16 which is 69" and i think i was the lowest, i did fine, if its what you ride normally then you probably have a higher cadence than others so you should be cool
