Was out on a ride yesterday and about 62 kms in I stood up to get over a small hill. Then snap! I had to hitchhike home.
I have the early 07 Liquigas System Six.
The Spindle broke. So my LBS is very apologetic and is trying to get the black aluminum crankset upgrade to replace it - at no cost to me. I will let you know what happens on this front. It appears that the problem relates to the overcooking process which created some tiny stress fractures it the aluminum. Im not entirely sure on that though.
I prefer to not think about the defect and tell people that I was so powerful that i broke the spindle!

I was bummed at first cause I thought this would put me out of commission for a week or so, but my LBS has offered to put another carbon one on for the short term so I can keep riding while this gets sorted out - gotta love creating a good relationship with your LBS!
