I've seen Weeksy's price and know the spec so it's included in the exercise. But there is merit in Weeksy's arguments and being very slow I would need every advantage I could get = bhp.
I'm not ready to buy yet and Weeksy wants to sell now anyway ...
But hang on Tim, I was cruising through some old posts and saw a thread that you started about getting a track bike and were potentially interested in the very same things I've listed above - what did you end up doing?
