All-City Aluminum Thunderdome Frameset
Steel may be the most comfortable material on real roads, but in the dangerously smooth velodrome, comfort takes a backseat to performance. The Thunderdome is made from 7000 series aluminum that is designed to make it lighter and stiffer than its steel brethren. It also features a shorter axle to crown carbon fork that also helps to make the ride stiffer and lighter overall. Together, this makes the Thunderdome an ideal velodrome race bike, perfect for quad-bursting pursuits.
