New Gruppo on older bikes

well I broke the carbon seat post and the carbon forks on my cross bike, not by crashing just hard riding. It could have been very nasty, and I absolutely dont trust the stuff.

My steel frame catastrophically failed last febuary, but thats because I hit the back of a taxi at 20mph.

staring nervously at my bike across the room. One of the spokes just snapped right there without me even moving the bike. Wierd. This ever happened to anyone else?

So have you given up on aluminium parts too?
