At age 52, I am happy to say, I have never been faster. I re-discovered cycling in 1985 when I bought a Peugeot "Canyon Express" mountain bike. I followed that quickly with a new Lotus road bike and haven't looked back since. I currently own 9 personal bikes and a bike shop full of new ones I offer for sale. I ride when I can, which is not often enough. This year I tallied around 2000 miles. Nothing I like better than to nail a technical section and have to wait for folks half my age to catch up. Of course this does not happen that often, but that's what makes it so sweet when it does.
The list

Add in all the old parts, frames and biking knick knacks I couldn't bear to part with, and I was kinda forced into the bike business just to have a place to put it all. I have been in the business now about 16 years.
