This is an pretty good product.
Pros lightweight, easy to install, bearings are durable
Cons with my carbon frame and these plastic cups, THE CUPS BACK OUT!!! So i repeatedly have to back off the BB preload or else the crank rotational friction increases drastically. As I race the bike each weekend i have been fooling with the crank/PF30 bb constantly! What a pain! Most recently a mechanic told me to use green loctite to prevent the cups from slipping outwards. I did that 2 days ago. I'll see if that fixes the problem. Basically i'm pretty unimpressed with the PF30 bb standard so far. Bearing friction tends to be high, exactly what I don't need.
