  • Where is the race? Would be good fun to come and watch! After my brompton racing debut at Nocturne I was thinking about giving it a bash - 58T chainring is a good choice, can you still fold?

  • St James Park, race starts at 7.15 this evening. I'm gonna head there soon to sign in, I think. Come on down!

    58t still folds fine. I seem to remember reading 60t is the biggest you can have that'll still fold but could be wrong.

    What I should've done is get a 13t sprocket to fit it, so I could run 58 x 12/13 rather than 58 x 12/16. Don't think the 16 is gonna be much use for this but can't find anywhere to buy the 13t by itself.
