My bikes have names, and I talk with them.
Dash is a 35 year old custom steel frame equipped with an Ultegra group, used for training, and touring. Lou is a full carbon steed equipped with a Dura-Ace group, used for century rides. Dash Too is a custom, all road speedster boasting a 1x SRAM drive train, hydraulic disc brakes and 35 mm Compass tires. And, Thatch is a modified mountain bike used for running errands.
They are my best friends 😂
There are advantages to having 4 bikes. It reduces the wear and tear on any one bike. The drive trains do not have to be replaced as frequently. I ride more often, even in inclement weather. And, it adds variety to the rides. Each bike has preferred routes. Thatch stays in the city. Lou likes smooth, fast surfaces. Dash likes longer rides on rougher, rural roads. And Dash Too likes all road surfaces and terrains.
