Sun Sept 21st, High-noon - LFGSS Track Day 2 at Herne Hill Velodrome

If you have a flip-flop hub then you can stick another sprocket and flip the wheel over or change sprockets when you get there. You should aim for mid 80s GI. I assume your charge has drops and you can easily remove the front brake? In that case you should be fine

I'm rocking with 46x14 (two fat ladies and a bit)
other than that its bar tape, tyres in good nick, helmet and bar tape.. anything else?

there a chance we can get there early and test the set up before racing?
