Coming Soon. Please contact our Customer Service team if you're interested in pre-ordering.

Specialized’s most aerodynamic gravel race bike they’ve ever created, the Crux 5 is a speed machine – inspired by the lessons of the Tarmac SL8 and decades of research in the aero discipline. Now, the Crux 5 Sport sits at the height of elite gravel racing for its unmatched speed, telepathic handling and balanced compliance to keep fatigue at bay. Sporting a Flow State Design in the FACT 10r carbon frame, it’s one of the very lightest frames currently on gravel, weighing in at an impressively small 897g without compromising strength and handling.

The Rider First engineering creates a bike that delivers the same unmatched performance of stiffness, compliance and handling in all sizes, including improved balance with shorter stems (in the longer size specific reach), increased confidence at speed with a slacker head angles and that “in the bike” stability that stems from a lower bottom bracket height. And, the Crux 5 Sport now has the ability to switch out the Pathfinder 700x45mm tyres for something much chunkier with tyre clearance up to 55mm whilst maintaining its effortless handling, just with better traction. The Shimano GRX 12-speed drivetrain offers a smooth shifting experience as you travel off-road whilst the Shimano GRX brakes keep speed reductions efficient in all conditions.

Race day ready when speed is key, the Crux 5 Sport will turn more of your effort into pure speed with its unparalleled aerodynamics and unheard of levity – and even better, it currently delivers the lowest real-world Time to Finish of any gravel bike ever made.  

Features: 

  • Flow State Design delivers a 897g frame - one of the very lightest on gravel
  • More aerodynamic at up to 5.8 watts faster with better handling - still nimble but smoother with better traction
  • Delivers telepathic handling, instantaneous acceleration and balanced compliance that reduces fatigue on the roughest courses
  • Rider First engineered and now with 55 / 2.2" mm tyre clearance for unmatched traction and comfort
  • Improved balance with shorter stems (longer size specific reach)
  • Increased confidence at speed with a 0.5° slacker head angle
  • "In the bike" stability with big tyres and a lower bottom bracket height
  • More efficient power position and tyre clearance with a 0.5° steeper seat angle
  • Aero Gains Breakdown: frame, fork and seatpost - 50%, Roval Terra Aero wheels - 30%, Roval Terra cockpit - 20%
  • Unbound Winner Sófia Gómez Villafañe’s Time to Finish at Unbound would be 9:58 faster on the Crux 5

Would recommend!
Color: White, Size: Queen
I bought this mattress topper for my teenage daughter for her bed. It was on sale when I purchased it and when it arrived I loved the quality and softness of the topper. Great buy for the price! It stays in place and fits as sized. I have yet to launder it, but I would assume it will wash up just fine. My daughter loves it and makes her bed dreamy.

Saved me so much money
Im loving this mattress topper. It has added a noticeable layer of comfort to my firm mattress without making it feel too soft. The cushion is plush yet supportive and has made sleeping more comfortable overall. The bamboo feels soft and breathable. It fits on the mattress with the deep pockets and stays in place alk night. Setup was easy and it fluffed up after unpacking. If you have a firm mattress and want extra comfort without replacing it, this topper is a great option. Highly recommend

Comfortable, cooling, and OEKO-TEX certified, it’s a great way to refresh any mattress.
This 3-inch mattress topper instantly upgraded my bed with a softer, cooler, and more supportive feel. The bamboo-viscose fabric is noticeably breathable, helping regulate heat throughout the night—great for hot sleepers. The 1200GSM down-alternative fill adds plush, cloud-like cushioning while still offering balanced support for the back and shoulders. It fits securely with the deep pockets and stays in place even when turning. After allowing it to fully expand, the topper fluffs up beautifully. Comfortable, cooling, and OEKO-TEX certified, it’s a great way to refresh any mattress.

Great upgrade for a rental apartment mattress
The mattress in my rental place is firm to the point where it almost feels unfinished. Instead of replacing it, I decided to try adding this topper. It made an immediate difference in the way the bed feels when I sit or lie down. There’s a nice cushioned layer that softens that “flat” feeling but still holds its shape. Another thing I noticed is how breathable it is. I expected thick padding to feel warm, but the airflow here feels better than the original mattress surface. Even after moving around, it never felt heavy or stuffy.

Soft and Comfortable Topper
I got this bamboo mattress topper for a small single bed we keep in our guest room, but I ended up testing it out myself first. The material feels soft and breathable, which is nice because that room can get a little warm in the afternoons. It adds a good amount of cushioning without making the bed too soft. After a couple of nights, my back actually felt better compared to the old mattress alone. I also appreciate that it’s machine washable, because our guest room sometimes doubles as a nap spot for my son after swim class, and spills happen. It dried pretty quickly in the dryer and kept its shape. Overall, it made the bed feel much more comfortable and fresh.
