Review: Raceface SixC Seatpost & Atlas Saddle

Raceface Atlas I-Fly and sixc seatpostThere’s alot of blathering in the industry about light, and cheap, and strong, but sometimes we only want to concern ourselves with light and strong. For those still listening, RaceFace claims of offer one of the lightest DH worthy seatpost and saddle combinations on the market – in the form of the Sixc carbon seatpost and Atlas I-Fly Saddle.

The pair will set you back $250, but is the weight savings worth it?

Weight

Raceface Atlas Ibeam Saddle WeightThe RaceFace Atlas I-Fly saddle retails for $100 was purpose built to take a beating and weighs 168 gms. For all the weight conscious downhillers counting their grams and calories, that’s 12 grams more than claimed.

The saddle is available in every color, so long as you order black. The good news, it’s also available in a railed design. Weight for that model with Ti rails is claimed at 220 grams.

Raceface Sixc Seatpost WeightThe Sixc seatpost is 350mm long and available in 30.9 and 31.6mm post widths. Claimed weight for our 30.9 post was 190 gm,but  it seems our post drank a small sip of beer before getting on the scale, and was 7 grams over weight. The Thomson Masterpiece seatpost which retails for $10 more at $149, has a claimed weight of 192 gm.

On the TrailRaceface Atlas Ibeam Saddle Close up

Since we’ve been waiting on a few little adapters to get the new downhill bike rolling, we stuck our post and saddle in the dirt jumper and unleashed it on the streets. Unlike Goldilocks, RaceFace hit up on the right size for the Atlas I-Fly saddle on the first try. It’s not too long that it feels XC-ish and not so short that it resembles a dirt jump saddle. The shaping is also spot on, with the rear portion of the saddle being narrow enough that it doesn’t impede your ability to get back quickly.

When cruising around, you’ll immediately notice how hard this saddle is. It’s a fairly thin and flat platform, but the plastic unibody construction makes it feel incredibly stiff compared to traditional railed saddle designs. We wouldn’t want to do any all day epics on this saddle, but it’s fine for smashing between the lifts on your downhill bike, or cruising the streets between spots.

Raceface Atlas Sixc Ibeam Saddle combination rear shotLike all I-Beam saddles, the fore, aft, and tilt can be adjusted via the use of a single hex bolt. We didn’t have a torque wrench handy when we installed the combination, so we clamped everything together using a small multi-tool. What we quickly found was that compact trail tool did not provide enough torque to keep the saddle in place, so we recommend using a standard hex tool to secure everything.Raceface Atlas Sixc Ibeam Saddle combinationThe Sixc Seatpost and Atlas I-Fly saddle may be at the top tier of what many downhillers might consider spending, but the combination appears to be incredibly well built and you won’t find anything lighter rated this tough.
