Q: How does the tube top work?
A: The tube top attaches to the seat post and neck (aka headtube) of a bike, effectively creating a traditional top-tube type structure for mounting on trunk or hitch racks. This is the solution for difficulty fitting kid’s, women’s, and odd-shaped bikes.
Q: Will it fit every bike? A: It fits most bikes and is adjustable from 14" to 30". If in doubt, the best way to tell is to try it out at a local dealer.
Q: Is it easy to take off? A: The TubeTop is very quick on and off, so you can leave it in the car while on your ride.
Q: Can I use the Tube Top adapter with my dropper post? A: Though it may work, we don't recommend it. We recommend using the Tube Top adapter with standard seat posts only.
