The legendary SuperX is BACK, reborn as a stripped down, souped up, pure gravel race machine—purpose-built for chasing podiums and PRs everywhere from Kansas to the local lunch-ride world championships. Its predecessor, the SuperSix EVO SE, set the fastest time ever for Unbound Gravel in 2024, and with the new SuperX, we’ve gone all in to make it even faster. Less aero drag. More fatigue-fighting compliance. Sleeker integration, and of course, less weight. Ready for faster?

Made to absolutely smash gravel races. Simple as that. This is full-gas road race performance engineered for the full thrash world of gravel. Elbows out, head down, get off the front and don’t look back. SuperX only has one destination – the top step.

FEATURES:

  • Fast & Light: Our KOM-winning road tech meets Unbound-winning engineering. The LAB71 SuperX is super aero and over 100 grams lighter than its predecessor, helping you stay ahead of the pack in this rapidly -evolving era of highspeed, elbow-to-elbow gravel racing. With gravel race speeds averaging well over 35 km/h, the LAB71 SuperX brings a whole lotta free speed over any distance.
  • Gravel Glider, Not Grinder: SuperX’s sophisticated carbon construction smooths out the rough, floating above the gravel to keep you cranking. Specially constructed flex zones in the seat tube, rear triangle, and top tube work as a system with the D-shaped seatpost to absorb shock and vibration, keeping your mind and body fresher longer.
  • Built to Take It. Tuned for You: SuperX’s Proportional Response carbon construction is tailor made for gravel racing and for you. Fully customized by size, precisely oriented layers of different types and moduli of carbon fibers deliver an ideal balance of weight, stiffness and durability for every rider. All backed by our lifetime guarantee.
  • Get 'Crossed Up: Is cyclocross your thing? SuperX has you covered. Throw on some 33c tires and hit it. With its straight-line speed, planted handling, and massive mud clearance, SuperX loves to battle it out between the tape. Oh, and the flat top tube is pretty nice on the shoulders too.
  • Rolling Fatties: Courses vary, terrain varies, weather varies. The SuperX fits tires up to 48mm for the frame and 51mm for the fork, with at least 4mm clearance on each side, ready for whatever tire the day demands. 
  • Delta Steerer: The Delta steerer design is great for gravel racing. It allows for clean cable integration from the cockpit into the frame, and a reduced frontal area for increased aero efficiency.
  • OutFront Geometry: OutFront pairs a slack head angle with a longer-than-normal 55mm fork offset, increasing stability and control on the steep and loose – while maintaining the snappy handling you need for quick  line changes and last-second corrections.
  • The Cover Up: A slick cover hides SuperX’s top tube bag mount. It's there when you want it, invisible when you don’t.
  • D-Lightful: The D-shaped design of SuperX’s seatpost enhances aerodynamics and boosts vertical compliance, reducing muscle fatigue so you stay fresh and fast for the final sprint.

This stuff works!
Size: 32 oz
I was sceptical but wanted to avoid replacing 2 rear tires on my zero turn mower. The tires were leaking air and had bad sidewall cracking. I found the use of the product to be easy and quick. I aired up the tires and rode around the yard a few minutes to distribute the product in the tires. It has been 4 days and both tires remain aired up. Previously both tires would already be flat within this timeframe. Excellent results for me!

Doesn’t work for a car Tire seal slow leak
Size: 16 oz
Does not work for a car tire. Had a slow rim seal leak. Out 32oz in still leaks the same. Do not buy. I got the one with fibers in it. It worked just fine. This does not work. Period. $30 wasted actually I purchased two so I wasted $60 when I could’ve bought probably a new tire

#1 Tire Repair
Size: 16 oz
This stuff is Fantastic. I have a riding lawn mower and one of the front tires, which is small, had been running low for a couple of years, we took it off. to fill it with the liquiTube and you could see cracks all around the outside of the tire. The liquid tube oozed out of one of the cracks and sealed , immediately. My brother rolled the tire around real good before we put it back on the track lawn mower. It has been 3 days now and today I mowed for 1 1/2 hrs and the tire as full as it was the day we put in the LiquiTube. This stuff is fantastic, it really, really works!
