Carbon vs. Aluminum Seatpost...Which One???(8 posts)

Carbon vs. Aluminum Seatpost...Which One???mek

Are there any arguements for carbon vs. aluminum seatposts? Durability vs. Performance vs. Comfort??? Looking at buying a Thomson or Campy Record (carbon) and wanted to know if carbon would have a softer feel or if aluminum would transmit any harsh feel. Any recommendations...

I'm a big fan of Campy Chorus and Record groups and have been using them since they've been around but if you look at the seatpost reviews you'll see that the Thomson post is rated better. The Thompson post has also been around long enough to know that it will last. The Record carbon doesn't have that on its side and I think I've even heard of a couple of them breaking but I've never seen it first hand. You could meet half way and buy a Ti post.
As to feel, I've used all types and can't tell the difference in the saddle. Your wallet, weight and ego is where this decision rests.

I'm a big fan of carbon, however this is one area where I would incline on the Thomson aluminum. My reason may be very specific, so it may not apply for you, but I put my bike on the workstand very often. With an aluminum seat post I'm much less concerned about crunching the post with the clamp. Mind you, this is pretty unlikely anyhow, but I thought I would throw this out in case it is helpful. From what people tell me there is no difference in the feel of the ride between any seatposts, provided they don't have something exotic like suspension.

I ride with a Campy carbon seatpost. Honestly cannot tell the difference in ride quality vs. my old aluminum seatpost. I really bought the Campy seatpost for it's looks and weight. Compliments my carbon bike extremely well. In regards to clamping the seatpost and possibly damaging it, I have not damaged it at all even after numerous times clamped to the Park stand I have. Hope this helps.

puts a lot more clamping force over a much smaller area than a repair stand, I wouldn't worry too much about damage by clamping. They seem to be pretty tough, and unless I heard from a manufacturer that clamping a carbon post was an issue, I would continue to do so.

The Thomson is often mentioned as a fine seatpost, which I'm sure it is, but it places the saddle much further forward than any traditional seatpost (at least 2cm). Even the elite model with setback, doesn't give the normal amount of setback.

If you can't get the saddle back far enough, your knee-over-pedal position and reach will be adversely affected.

Take a look at the position of the front of the seat rail clamp on you current post, before picking a new one. Most traditional posts have the front of the clamp located near the centerline of the seatpost.

A good 2-bolt post with infinite angle adjustment is the ITM Millennium. This post allows a little more setback than the Campy post, and a larger adjustment range, due to it's narrower clamping area.

The Thomson with less setback actually helped me. Having my knee just a few millimeters forward of the pedal has actually improved my spin and seems to put less pressure on my knees.

If it works for you, but even with the saddle all the way back on a Thomson, the saddle's going to be than a few millimeters further forward than a traditional road post. The difference is at least 20mm, maybe 25mm.

This post is only likely to work for those who already have their saddle pushed all the way forward on a traditional post. A longer stem may also be in order.
