Since I regard this as the "performance branch" of the 50+, I'm posting here even though I don't race. (I do plan on riding up some mountains in Italy next July though.)
After a good season outdoors, my chums and I have started back training indoors in the Velo Garage and I'm using my power meter again. The social aspects of these sessions are in a thread over in the normal 50+, but I thought I'd share the more performance oriented stuff over here.
My first ride with the powermeter last Thursday night kind of surprised me. Riding intervals of 15, 10 and 5 minutes at 70% effort (3 minutes recovery between), I blew away last year's power records by about 40 watts evenly between the 5 minute and 30 minute periods. These aren't great numbers for you racers, but shoot, I feel pretty good about it. Normalized power was 180w.

New 2013 Billydonn: stronger engine and improved aerodynamics.

Weight is no longer 218 as shown in the graphic... it's in the 206-8 range.
Anyone else who wants to post some indoor pictures, numbers ... I'd be interested. And I will update my numbers here from time to time too.
