I have a PT G3 and my only complaint is the alloy free hub. I dug some 3mm bite marks into it while doing sprintervals. I downgraded to a tiagra cassette after taking a double chain whip to un-bed them from the hub. LBS who built my wheels (which otherwise I love) called cyclops and they said the had a steel freehub for $50... but wouldn't warranty mine... which is 2 months old. I will most likely never purchase another PT hub, but I am happy with my current configuration... the tiagra cassette was $10 cheaper than the new free hub ironically, so it was an acceptable fix; granted I would never had to do it if it hadn't been so soft.

oh and on stages, they will not accept your crank arms on trade.
