So just following up on a part we listed previously, Atomlab is soon to bring out their own hydraulic brake rotor which basically replaces your headset spacers. Check out their new brake series for a complete brake system to power your dirt jump bike.

Now for all the Cam McCaul's out there wanting the ultimate jump bike - just need to find a downtube water bottle mount for a road bike shifter :)
