SixC Seatpost: Only Truly Rated DH Carbon Seatpost

Rating: Featured Member Review
The Good:

DH stiffness and durability, Light weight, Damping perks that only carbon offers

The Bad:

Wish graphics came in as many color options as the SixC bars do, Claimed weights a bit off.

Overall Review:

I initially picked up the Race Face SixC carbon seatpost because I had previously purchased another carbon seatpost (Bontrager XXX) for my Session 9.9 but didn't have that great of an experience with it. I heard thewas almost as light (30 grams heavier) but offered DH rated stiffness and durability. Because of my previous negative experience and the promise of something better, I had to tryitout.

I picked up theSixC seatpost along with the Race Face Atlas I-Beam saddle.Afterabout 3 months of riding with it, here are my impressions.



Out of the box:


Pulling the post out of it's packaging, I was presented with, yet again, anotherultra-fine piece ofcraftsmanship. The carbon material and finish were bothflawless. Attaching the Atlas I-Beam saddle was as simple as loosening one bolt and sliding it in. No tricks, no dropped parts on the ground. After installing it on the bike, adjusting the angle was even more easy. Loosen, slide/rotate, tighten.

This saddle went on my 2016 Scott Gambler and had to cut it to tube length of 280mm. Weighing in at 187 grams, I feel the claimed weight of 190 grams for the full length might be off by as much as 10-15 grams. It went on a DH bike so like all that matters but still good information to know.


On the Trail:


The I-Beam construction of this post is amazing. Complete stiffness from seatpost clamp to ass. If that's what you are looking for, stop reading and order this post now. Besides being the stiffest carbon post I have had on a DH rig, it always offers a small amount of damping from the high speed bumps that are ever so common on the long flat sections during a race. It's nothing crazy but can notice a difference.


The main reason I was upset with my previous carbon seatpost was because the thing never stopped creaking which in turn really my gears as an OCD mechanic and rider. The I-Beam of the is a much simpler design than my previous post and hasn't made a single sound. Solid as a rock. The guts of the I-Beam are made from fancy plastic which makes me slightly nervous incase I have a "Nicholi Rogatkin – 2015 Rampage" style fall. However, if a part breaks, even if it were my own fault. I feel Race Face would do their best to make it right. They are a great company.



Bottom Line:


If you get excited by carbon, don't mind throwing down some extra bills for a few less grams, and love it stiff. This is the post for you. Hasn't on my yet which makes me feel it's an excellent option for people that like riding their bikes more than working on them. The claimed weight was a bit off but not by much. Great graphics, just wish they made them in multiple colors. 5 stars for function. 5 stars for looks. 3 stars for misleading spec information (weight). Average rating 4.5 stars.
