I am in the process of building my first 29er. Need to spec the bars and post. I have been a Ti and Steel guy in the past, this is my first Aluminum frame. Asthetically, Thomson Post and Al. bar are a great fit, but wondering about too jarring a ride. How do most folks feels about carbon for applications such as seat posts and handlebars?? I am about 185 in riding gear and ride strictly XC (stairs are drops to me). The new 26" Salsa carbon bars look interesting, but I have always been a little leery about the durability of carbon for these applications. Thank you in advance.
