I am planning on selling my Rip 9 and entertaining the idea of a Carbon Jet. I have an AL Jet 9 also and love it. I went over the RIP 9 very good over the weekend. It looks like new with the exception of a few rock hits to the underside of the downtube where there are 3 or 4 dings/small dents from high speed rock hits. Where I ride there are LOTS and LOTS of rocks. Some large, some small. They can be kicked up and whack your cranks, downtube, shin, etc. Some at high speeds 20+. My question is: are there any precautions taken in the design/manufacturing process for the Carbon Jet for this type of occasion which is inevitable in a riding environment such as mine? I know there is a 5 year warranty (which is great) but will the Carbon Jet survive these types of blows? When would you know if you need to send it in for inspection or whatever? I don't like the idea of not having a bike for any length of time. If a frame did have to be sent back, what sort of turn around time could be expected?
