Specialized launches the Epic 9 – claiming the lightest full-sus XC frame ever made

If you care about cross-country racing, or just enjoy watching the weight-weenie arms race escalate to increasingly absurd levels, this is worth paying attention to.

The headline claim: a 1,589g frame weight (medium, with shock, hardware, seat collar, axle, and water bottle bolts included), which Specialized say makes it the lightest full-suspension XC race frame in production. That’s 129g lighter than the nearest competitor, and 179g lighter than the Epic 8 it replaces.

To put that complete bike weight in perspective: the top-spec S-Works Epic 9 Ultralight LTD tips the scales at 8.5kg. For a full-suspension mountain bike with 120mm of travel front and rear, that is an extraordinary number.

The savings came from full-frame finite element analysis optimisation – essentially stress-mapping every gram of carbon to work out where material wasn’t earning its place. The biggest single saving (110g) came from removing the SWAT in-frame storage that featured on the Epic 8, replaced by an external bolt-on box. Whether that’s a pragmatic weight decision or just Specialized giving up on an idea they should have abandoned earlier depends on your view – but the result speaks for itself. The rear triangle shed 37g, the seat tube 17g, and the main pivot hardware another 15g.

It’s not just about the weight, though. The suspension kinematics have been revised to reduce friction by 11% compared to the Epic 8, with a lower leverage rate at sag to improve pedalling efficiency. The three-position damping setup – Wide Open, Magic Middle, Sprint-On-Lock – returns. The geometry is close to the Epic 8’s modern XC feel, which was well-regarded, with minor adjustments to head angle and stack.

The Epic 9 also simplifies the range: it replaces not just the Epic 8, but also the Epic World Cup and the Epic Hardtail, folding everything under one name. Pricing runs from $7,500 USD for the Expert build up to $15,200 for the S-Works, with the Ultralight LTD landing at $15,250. UK pricing to be confirmed. Christopher Blevins — who won both the XCO and XCC overall titles in 2025 on the Epic 8 — will be on the new bike when the World Cup season kicks off in South Korea this weekend.

  1. Weren’t they the shocks that were more often sat on a workbench waiting for parts/service rather than next to the rear wheel?

    The original epics were pretty reliable, mine still in the shed. 
    The 2020ish epic evos had real problems with their integrated shock, yoke, brain set up. Mine had a new rear shock under warranty. Service is a pain as it requires the whole rear dismantling to get the shock off.
    The new 9 looks great, but the price is scary. It kinda looks like a hybrid of the previous world cup and 8, and purely for speed and not sure something quite so lightweight will lend itself to downcountry. 
    My epic Evo is great for coffee rides and long days, hasn’t seen a race.


  2. No chance, not with the third rate components hung off that.

    My Chisel Comp was decent enough value when I bought it at half price.
    Not sure where they got the original RRP from for a bike with SRAM NX… 😳

  3. The original epics were pretty reliable, mine still in the shed.
    It was the early 00’s that i used to see them in our local spec dealers, shocks off. Waiting on spares/replacements for the brain shock. (Wasn’t there a remote/hose version and a normal sort of right angled piggy back as well?)

    Half price yes, better then buying the frame set. There seems very little value in specialized full bikes at RRP.

  5. If I had the money (come on lottery win….) I’d definitely buy the full blingy bling version and use it for mincing around the Peak. It would never see a race, but it would see some beer gardens.
