Frame dent=not safe to ride
My Specialized Roubaix has a dent close to the bottom bracket on the outside of the chainstay. It had obviously been caused by a dropped chain. I took the bike to the Specialized dealer where I bought the bike and they said it "should be OK to ride". Not too convinced about this I took it to Specialized dealer #2. They were much more doubtful and suggested that the Specialized rep take a look at it next time he comes by. So I just got the call from the shop, that the rep had recommended against riding it anymore.
The dent is about 2 mm in diameter, round and almost 1 mm deep. I know it is hard for anyone here to judge the severity of this but I am just wondering if the rep said this due to liability issues and being overly cautious (sorry I have no pictures).
The shop suggested a possible repair by Calfee, who apparently does these things and secondly a new frame from Specialized under their crash replacement program that discounts frames about 30%.
It is pretty easy to put dents into carbon frames and I started to think of the possibilities of something similar happening to more expensive carbon frames. I have been happy with this bike, but now I feel luke warm to bying another carbon frame at all.
I would appreciate any opinions with regard to the necessity of repair/new frame or go with other materials. So much for looking forward to the rides during the upcoming holiday

If you have the money, why not look into other materials, like Reynolds 953?
I used to like carbon a lot, but this sort of issue has put me off. Now I would much rather have a 953 frame.

If this happened to steel or even aluminum it would be a non-issue.
So much for plastic bikes...

The chainstay is the most common location for frame breakage in any material (even steel) and is not considered particularly safety critical. You notice the bike feeling a bit soft and making some funny noises. Lance A. sprinted to a mountain-top victory in the Pyrenees on a carbon trek with a shattered chainstay.
Other locations for breakage have more immediate results (head-tube, fork, seatpost, crank) and will result in injury.
It is up to you though to decide. Personally I wouldnt ride a carbon frame that was damaged in such a highly stressed area.
