seatpost

further to my original post about buying and enjoying a windsor clockwork after some upgrading of parts, there is one thing i will likely be replacing in the near term - the seatpost.

the stocker is an alu. piece, and i feel that a cf or steel one would soak up a little more road "noise"

does anyone have an opinion on which material will mate better with the steel frame, and suggestions on a budget post in either material? thanks.

note: i'm not saying i NEED a new post, more like WANT one, at which point i will be very satisfied with my bike.

You are not going to notice a significant difference changing your seat post, especially if the frame is steel. Change it for aesthetics if you'd like.

coupling different materials is what reduces vibration frequencies - steel on steel would makes things worse (are steel seatposts even made..?).

carbon would be your best bet, but wider tires would help more.

if you're going for carbon, this is quite a deal: http://www.probikekit.com/display.php?code=A9183

^^^ wow that is a steal, any idea if it's safe to order from them now with the recent wave of credit card scams oddly associated with them?

also, i didnt know that the difference in materials helped dampen vibration, as opposed to the individual qualities of the particular material. i guess going with carbon is the way to go. thanks for the above link!

I dont know if the situation has been cleared up since I dont know the details, but you can always get one of those prepaid credit cards to be safe.

i've used carbon in steel with good results; ti is also a good option (purportedly, not from experience).

Unless your post bends or breaks, its the last thing you need to change. Sounds to me like you might have an uncomfortable saddle and you are blaming it on the seatpost.

Whatever the case, the idea of changing your seatpost to dampen vibration is absurd. Do you have any idea how much fat is in your perineum...even if you are skin and bones, there's several inches of fat down there, dampening whatever vibration is transmitted through your saddle. The ride characteristics of different materials are relevant for frame building mostly because you are free to vary the tube diameters to achieve desirable ride characteristics. On the other hand, the diameter of your seatpost is going to be the same regardless of material. Realistically, you aren't going to notice a difference unless you use a suspension post. If you want to dampen vibration get bigger tires and run lower pressure.

At least you can admit that you don't really need a new post. If you have the urge to waste your money, then buy an aluminum Thomson. Its the strongest, most highly regarded seatpost out there, and basically as light as carbon posts.

^^ yea, i'm trying to be very upfront with the fact that i dont need a new seatpost, and i dont expect to feel much of a difference with a new one. i'm not at all uncomfortable now, i have the best saddle (for me) that i have ever ridden on the bike, and i love the geometry in general.

No problem with upgrading bikes for fun. My strategy is usually to unnecesarily upgrade everything until I have enough parts laying around justify a new frame and....viola, a new bike. Then you put the original bike back together and decide again that it needs upgrading. I started with two bikes and I've upgraded so many times that I now have six and working on a seventh. I actually ride all of them, so its not really a total waste.

hell yea, i do the same thing. sometimes just having something like a new seatpost is somehow super motivation to go for a long ride. plus, as you mentioned, i've always wanted to try one of these thompson seatposts, everyone talks about how super they are...

To the OP. if you're not aware already, you can actually get a gently used thomson elite for dirt cheap on your local craigslist.

Thomson, not Thompson
Don't worry I made the same mistake.

as has been said...changing the post will do essentially nothing to improve comfort. try some 25c tires or less psi or both.

as has also been said...a trick post is a trick post. if upgraditis is the root cause, carry on.
