Neat Chip

I ride regularly outside, usually 26 miles a day, weather permitting and longer rides in the summer months.
My bike has Shimano Ultegra and Dura Ace is the top dog - more than I need.

It refers to all the components on the bike.
Gears, brakes, derailers, etc.

The weather in NJ is taking a turn for the worse, so this may be sitting for a couple weeks.
