Herne Hill Bike needs

Hey, haven't been up there myself but definitely want to give it a go, apart from bars and brakes, is there anything else I need to know?

Also, i'm currently running 42/16, so would I be better going for a 45/13 setup, or a 42/12 but having to shorten and lengthen the chain when I arrive and when I leave, as I will be cycling from Uxbridge.

@ Herne hill I run 42/13 if its windy or 44/13 when its not to bad out there.

STW FTW!!
