The Atlas I-Beam post takes the Worldcup proven I-beam head design and combines it with a Race Face designed seatpost tube. The SixC Carbon post is manufactured with a leading edge composite material which reaches Raceface's high strength requirements at an impressively low weight. The carbon layup tube offers outstanding fatigue & impact strength. This is Raceface's lightest ever downhill-capable post.

The I-Beam System uses a single, easy-access 5mm bolt for quick and simple adjustments or saddle changes. Micro head design allows precise angle adjustment. 2014 clamps and 6061 cold forged aluminum head. Patented head design is lightweight & distributes loads more efficiently than conventional seatpost head designs. Offers unprecedented adjustability - with tilt adjustment completely independent from the fore/aft adjustment.
