We made Crux, the lightest gravel bike in the world, even lighter. With the unrivaled capability of massive tire clearance and performance gravel geometry, it’s not just the ultimate expression of gravel performance—it’s your one-way ticket to gravel enlightenment.

With UDH and the all-new SRAM RED XPLR, the S-Works Crux drops another 102 grams. Featuring Roval Terra CLX II wheels, Terra Bars, Alpinist seat post, S-Works Power Saddle with Mirror, and Pathfinder Pro tires, the new S-Works Crux with SRAM RED XPLR is our most premium build.

  • Lightest: 725g S-Works 12r frame. We took the breakthroughs that made Aethos the lightest bike ever and applied them to the Crux. The result? A gravel bike that climbs like a dream, floats over nightmarish terrain, and weighs less than a full bottle in your cage.

  • Capable: 47c/650b x 2.1” tire clearance. More clearance means more capability. With Diverge-level tire clearance, Crux takes you anywhere you can imagine at full gas.

  • Responsive: Nimble, supple, and reactive. Responsive at the pedals. Supple in the saddle. With performance gravel geometry and race-influenced fit inspired by Crux’s iconic history in ‘cross.

  • Now equipped with UDH - Universal Derailleur Hanger - and built with the new SRAM RED XPLR, it features a 13-speed 10-46 cassette, power meter, updated lever ergonomics, and brake calipers that reduce brake effort by up to 80%.

Perfect bike!

It's my third one. I love every single thing about it and I use it for gravel, road or touring. There is nothing that this bike can't do and it does it perfect. SRAM XPLR is a match made in heaven for Crux. You wont regret:))))

Crux Sworks - First month

After hesitating between a new road bike or a gravel bike, this one blew my mind. So far happy about the investment and it is a joy to ride it everyday. Luckily with this one also with colder weather, the motivation is there as there is less risk as with a road bicycle. Quality great and it feels like all the roads are possible with the competitiveness of a road bike on no matter what terrain.

Amazing Bike

I also have a Diverge and they are different. One is comfortable and one is fast. This bike is fast. You almost can't keep up with it. You have to keep shifting gears. It just keeps getting faster. Build quality is awesome. SRAM 13 speed is best shifting I have tried. Doesn't matter how much power you are putting down it shifts quickly and solid. Great Bike!

It's the BEST all road bike - PERIOD (I bought last year Crux S-Works).

I wanted a bike which I can ride on tarmac/gravel very fast with comfort...basically just start from home. (I have spur/rail/5010). Demoed following brands: Cannondale, Cervelo, Giant.....Liked Giant. Later demoed Crux and fell in love....especially S-Works. I demoed all Crux models 2024/2025...Including DSW/S-Works........But I bought 2023/2024 Crux S-Works because I could not find even 5% percent difference even with 46 tooth going uphill. Weight: With Fox Transfer SL 70mm, Tubeless and Pedals ME03T/218 Grams....Total weight of bike is 16.75 LB....Which is INSANE. Definitely I can say Specialized is BEST brand out there with the best bikes in each category....especially S-works. You cannot go wrong with this it's best of both worlds (Road + Gravel)...and there is no competition even $2600 DSW is better that 7K Giant/Cannondale/Cervelo. I have taken ONE STAR for one Negative which is price.....:-) But you are getting the BEST.

Great Purchase Experience

I will edit this once I have the bike for a while. I just wanted to say how good the Purchase Experience was. Once the order was placed it shipped the following day. Expected delivery is only 3 days away. That is great that you can order the bike and have it that fast.
