The one thing I love about these carbon fiber boards (over the other wood/composite MTB's available) is the flex - really does help to absorb the harder hits but a slight trade-off with top speed as it also increases you chance of speed wobbles if you're running a looser suspension or cornering feedback from spring trucks.

This has served as one of my main R&D boards as I use it to test just about every part I make, I've put over 500 miles on this setup and it has been by far my favorite board built to date!
