I've switched to Sram XO 10 speed gripshifts for the new handlebars, this ment I had to buy new derallieurs (I got some nice used Red on ebay) So I put the old Dura Ace on my Cannondale yesterday and will do 10th gear trials now.
If I'm still going up the hill faster, I'm going to go 15 miles to Stanford University and talk to the engineering department, and see what they think. I hope they don't just argue about it. I will get back to you.
