ti versus carbon seatpost?(9 posts)

ti versus carbon seatpost?rgass
Aug 19, 2003 9:07 AM
I currently have a Litespeed titanium seatpost on my Litespeed Tuscany (bought it used, the seatpost came with it). However, swapping saddles on Litespeed's seatpost is a tedious affair. I want to switch to another seatpost, so I can swap saddles easily depending on whether I'm going for a shorter or longer ride.

I'm considering U.S.E.'s Alien seatpost, which comes in a titanium or carbon version. Is one seatpost material significantly stronger than the other? Does one material offer a smoother, more comfortable ride? Is another seatpost, Like Easton's EC 70 or 90, a better bet?

I'm not a particularly heavy rider (148 lbs) and most of the riding I do is either uphill or down--very little flat terrain in my area.

I'd appreciate any insights or experience folks might offer.

If you are going to be pulling the seatpost out of the frame frequently, I would go for the ti post. ex. you are taking it apart to put it in a bike case.
I just don't think carbon will hold up to all the scratches and abrasions, not to mention the constant crush potential of retightening the clamp.
Carbon is said to offer more vibration dampening to the rider, but all things in your post considered, I'd personally go for the Ti.

Find a saddle that is comfortable on all rides and stop switching it.

why do you want to swap saddles depending on the length of your ride? Can't you find a saddle you like and just stick with it? I think that's what everyone else does.

A carbon post will not make any difference in the ride of your bike. I've had carbon posts and aluminium posts and could never tell the difference. Carbon looks cool though.

If I were you and wanted to do this, I'd mount saddle #1 on your existing seatpost, buy another seatpost and mount saddle #2 on it. Then just switch the whole post/saddle at once. I did this once on a bike where I had a rack mounted to the seatpost (they both had the same saddle though -- Selle Italia Flite). Personally, I find putting a saddle on, and getting it set up correctly to be a pain in the butt, and try not to do it unless I have to.

You evidently do not have children.

I've never met anyone who thought that a U.S.E. Alien seatpost was easy to adjust. If you plan on using one, and are going to be constantly swapping saddles, I hope you have *alot* of patience or a little bourbon handy. It can be done, but you need to know how to get it tightened properly after re-installing a saddle.

Goodluck, Bob

P.S. If you do a search on Alien seatposts here you can see some of the troubles you might expect and also some remedies for them.

For someone who swaps seats frequently, the Alien is NOT the post for you. It is the only post I know of you need to bang on with a mallet to losen the clamp.

That said, I have a alien post that I like very much. I understand and can appricate others problems with it but for me it works.

If you really need to use different saddles, why not use two seat posts as well. It is alot easier to get you saddle height right than to make all the other adjustments.

With the others, I vote for a new saddle.

Good luck,
JC

I just bought one for a ridiculously low price of $65.99 from World Cycling Productions. It is very light (195 grams) and will last for a long time.
Use anti-seize compound with a Ti Seatpost...PdxMark

it might not matter if you're switching posts all the time, but Ti-on-Ti can easily seize. That said, I have a Chorus Ti post on a Litespeed with no problems (and a bit of anti-seize on there to be safe).

Thanks for all the input. Your collective insights were most helpful.

It sounds like using two different seatposts and saddles is the way to go. That way I won't have to futz with each saddle's fore/aft position and tilt every time I swap seatposts. It also sounds like a ti posts would be more durable if I'm going to be reclamping them on and off.

I'll check out the Campy ti post as well as the U.S.E. Alien ti.

I envy those of you who've found one saddle that suits all your riding needs. I prefer different saddles for different types of riding.

Quite often, I ride up steep inclines (Mt. Baldy road for those of you who are familiar with SoCal). For climbing, I like to use the lightest saddle possible, comfort be damned. At other times, I go for leasurely rides with friends on fairly flat roads (Newport's back bay and the Santa Ana river trail). Comfort trumps weight on those rides.

I can't be the only one who notices the trade off between speed/weight and comfort. The saddle reviews people have written are replete with tales of sore arses. And there must be a reason every cycling store I've been in sells a variety of butt creams.

I would liken changing saddles to the different between using tubes versus solid state gear for high end audio, or different knives when cooking; a bread knife, a butter knife, and a paring knife all serve different functions. When I go running, I wear different running shoes for pavement, cushioned track, or a treadmill.

I also change wheelsets depending on the type of riding I'm doing. But then, I enjoy tinkering with my bike. If I could afford it, I would own two or three different bikes so I could tweak even more.

Thanks again for the input.
