For Sale: Burls Ti track frame, fork and parts

crane before you sell, I'd advise you to go and speak to scherrit, and get sized, if you haven't already and see if that and some foot beds, might not overcome the knee issues. Shame to see a bike you spent so long, building up disappear from its rightful home, because of an recurrent injury which could be sorted.
if you've already seen a bike fitter, and there's no way its gonna work, my apologies and good luck with the sale..

This guy is a colleague/good mate of mine, he did the frame for me and helped me fit it up when it was finished
