|Best Seatpost for Chipseal||Ultegra|

|I am wondering what is better for dampening the ride on chipseal- carbon or titanium? My thought was perhaps a carbon post and a saddle with titanium rails. Any experience with this setup?|

|The exposed section of seatpost is so short that I doubt anything will make a difference. Nonetheless, everything I've read indicates that carbon transmits less vibration than any of the metals. However, the difference will be miniscule compared to your tires, frame, saddle, shorts, etc. You'd be much better off just lowering tire pressure 5 psi, unless you are already dangerously close to pinch flat pressure. Alternatively install fatter tires and lower pressure a bit.

|Just rode about 10 miles of chipseal over Fremont Pass last weekend on a carbon post, ti rail saddle. Everything was still miserably numb after 3-4 miles.
No good fix, and ride softening is more easily accomplished by changing tires, not seatposts.

|When I got a Thudbuster seatpost for my rigid mountain bike, I tried the old cheap post ($59.95 Post Moderne from Supergo) on my Atlantis for a few rides. That's a comfortable frame anyway, and it didn't make much difference. One thing it DID do well, though, was take the edge off that chip seal buzz.
Long term, the best thing I've tried is bigger tires at slightly lower pressure. I'm using 35s most of the time now, at about 80 psi. Not as slow as you'd think, and very cushy.

|Thanks for the help guys. The main reason I ask is because if I go much larger than 700x23 tires, I dang near have to let air out of the front to get it past the brakes. This was pretty much what I expected to hear- Thanks!|

|If they are average either carbon or ti will be about the same. But if chip and seal is being charitable and they are more like rubble and oil then actually the ti seatpost will be more comfortable. The carbon doesn't flex but ti does so if the bumps are larger ti is a little better and usually cheaper too. Either will be better than aluminum, although the difference is not great - about like taking a few psi out of your tires. But since roads seem to just keep getting worse every little bit helps.|

|Thanks! As is the same everywhere else, we have a little bit of everything including the bad chipseal you described. I've often thought it would be fun to organize my own ride that only road crews and event organizers could ride in. I would call it the Chipseal Century and you could only ride it on a 650 full aluminum bike with the stiffest possible wheelset. I swear some of the roadwork around here is done by airdrop.|| |
