A lot of travel from a small shock
Why does the Thunderbird FR frame have 180 mm of travel when the shock only has 75 mm?
At first glance, the answer seems simple: it’s all about the suspension leverage ratio. But in practice, the topic is much more interesting.
In this video you will learn about:
- what the frame leverage ratio really is
- why not every frame works the same way
- the difference between linear, progressive, and regressive leverage curves
- when an air shock works better and when a coil shock is the better choice
and much more !!
