Top Tube

What is Top Tube?


1.

The section of a bike frame that connects the head tube (where the forks go) with the seat tube (where the seat post goes). Usually 20-21 inches on a BMX bike. A shorter top tube generally means a shorter wheelbase, therefore making the front end easier to lift. Flatland frames commonly have shorter top tubes (~18.5") for ease of maneuvering. A tall rider may find bruised knees as a result of a top tube being too short.

Jack: Yo, my top tube is 22 inches!

Jill: Compensating for something?

Jack: Blow me.

Jeremy: HAHAHA! That's what you get for trying a flatland trick!

<James moans>

James: Yeah, I was looking into a flatland frame with a shorter top tube...

Jeremy: Panzy.
