I have a question though, I recently purchased a set of BT's 021, but only had the front installed due to cupping. The front has over 500miles on it, and I was contemplating in having the rear installed before I leave for VT. I had 8600miles on the stock tyres, wear band on the rear is starting to show with some squaring off and plenty of rubber on the edge for leaning. Should I wait until after the VT meet or get the new 21's installed on the rear. If I go with the latter part, I'll have about over 230miles to scrub off the new tyres before our ride on Saturday. What you guys and gals think??
