    Carbon seatpost rails, yay or definitely nay?

    I've always avoided carbon rails because of cost and personal worries about durability... but there's a saddle I've been trying to get for some time and it's finally available but only with carbon rails.

    I know my seatpost is okay for carbon rails, just hoping to get opinions from people who've actually ridden saddles with them... are my fears misplaced?

    3/28 Edit: I know shape-wise the saddle will work for me, I have ridden same saddle with alloy rails for a long time but it was destroyed in a crash. It's taken a long time for me to find a replacement with the color scheme I wanted but I have only found that with carbon rails.

    have a Selle Italia SLR w/ carbon rails...it's uber-light and fits my tush nicely.

    have about 16K miles on it with no issues.

    I've used carbon railed seats for a long time with no problem. My only advice is to get a seat post that has clamps that support the rails the full length of the clamp (both top and bottom) and not one that just pinches the rails in just a couple of places.

    I've been using a "Specialized Romin" with carbon rails on one bike and with Ti rails on the other bike for about 4 years now. I've noticed no problems with either.

    They're fine and are durable in normal use, but i've also seen them damaged in stupid freak accidents. I can't imagine getting very excited about a saddle i haven't put thousands of miles on, what's up with that?

    I had the same saddle with alloy rails and put a lot of miles on it, liked it, but it got destroyed in a crash. It's taken me a while to find another with the proper color scheme, and now that I've found it, it's the carbon rail version.

    Thanks everybody for your feedback.

    If you want a certain saddle for reasons of being comfortable and it's only available with carbon rails, I suppose that's a unique situation. (I doubt you know that's the case because you said 'finally available' but whatever).

    But under normal circumstances I just don't see the point. You want to make sure you have an appropriate clamp that fits in the middle of the rails but I don't think there's much risk however I don't think there's any reward either so why bother taking any risk. But like I was saying if that's the only way you can get a saddle that would work well for you that's an exception to no reward.

    Currently use both the Shimano Pro Stealth carbon rail and alloy. Previous to the Pro I used Specialized Romin carbon and alloy railed saddles...Durability has never been an issue for me. The main difference I have found with carbon rails v. alloy is the carbon railed saddles are less compliant/stiffer. Slightly less comfortable.

    I recently switched from a Fizik Arione (Ti rails) to a Fizik Arione 00 (braided carbon rails). I'd guess I have 500 miles on the saddle... and can't tell the difference. I've heard the carbon rails take some of the vibration out. But, come on... just how sensitive are these guys' assess if that much carbon makes a difference? Maybe I'd feel it if ditched the chamois and aired up to 200 psi.

    Not sure if you are replying to my post but, to be clear I stated alloy was more comfortable...ime

    How much of you weigh? That would factor into the durability question.

    Your weight may factor into the durability. I'm a Clyde, right at 200 lbs, and wouldn't ride carbon rails. Reason? My riding partner, who is just under 200, maybe 190 or so, had a saddle with carbon rails. He was doing a hilly organized century and was about 2 miles from finishing when a rail broke suddenly causing him to crash. Broke his collarbone and have him a good case of road rash. Plus ruined his Orbea Spirit steel frame which he loved riding. We both vowed off carbon rails afterwards.

    Nah - just a general comment. I think the cost of carbon parts is often justified because it's "more comfortable" "takes some of the vibration out" etc. Ya hear this a lot with handle bars.

    Full disclosure: I have have carbon handlebars, a carbon stem, carbon frame, carbon fork, carbon wheels, carbon seat, carbon cranks... carbon shoes. My bike soooo comfortable ;-)

    Right now I'm grappling with the high cost of the saddle...
