Just one? No way.
Now, I'm not like these other biking playboys who have to have the latest and greatest velo idea to add to their ever increasing stable. But, I admit that I have more than 1 steed and I could not live without them. (well, maybe I could stand to let the Haro and the Nishiki go and probably will someday. Soon.)
I have my Orbea for road riding.
I have my Hei-Hei for off road riding.
I split my time equally between the 2 and I'm in domestic bliss.
