Cervelo's new P5X was launched in fine fashion with a really cool display on Ali'i drive. My favorite thing about the bike is the one-bolt stack adjustment. The pads telescope up and down as a complete unit, like a seatpost. I had some discussion with Cervelo Co-Founder Phil White about disc brakes in general, and although I'm not sold on their appropriateness for triathlon, Cervelo is not the only company marching forward with this theme.

BMC also released their new Time Machine 01 and 02 bikes. The thing is a UCI-legal rig, very clean when all put together. It does look like quite a bear to work on, however. The brakes are set up with an extremely complicated cam system in the stem unit, that with practice, can take 'only' 20 minutes to take apart for travel, according to BMC. Other than the potential mechanical difficulty, it does look like a very clean setup.

Parlee made some waves this year when they announced their disc-brake bike, the first in what has become a small wave of disc-equipped tri bikes. They had this colorful one on display.
