The reason you see a lot of Tarmacs is because they are exceptional bikes for many riders, but not the only ones...
Components? Wheels? Size/Fit?
We all have our preferences... color of my bike is the last thing I'm thinking about at 80 miles into a long, hard ride. You're '80' may certainly bring different Qs to your mind...
WHEELS !!!! ?
Ride On
