Did Giant Turn the 2026 Life Time Grand Prix Into a Season-Long Product Test?

2026 has been a massive year for the GIANT Group. To add to the many product launches and move announcements this year, on March 3 2026, Giant and Liv announced a multi-year deal to be the official bicycle sponsors of the Life Time Grand Prix. The release promised a “significant presence” at all six races, support for Giant and Liv dealers near each venue (demo rides, athlete meet ups, in store events), and a tie in with Life Time’s clubs that gets Giant (AKA Stages) into their cycling studios. Reuben Hernandez, who runs marketing and retail for Giant Group USA, framed it as a way to get in front of people who race on Saturday and are in the gym the rest of the week. This partnership made sense to me, considering  Giant’s acquisition of Stages in September of 2024. Life Time has tens of thousands of spin bikes now in clubs across the country.

Back in June at Unbound, we spotted a prototype Giant Revolt that I was able to sneak some photos of in Emporia. That bike had a bunch of interesting features: a new frame, one piece cockpit, a 50mm CADEX Max GRX wheel that technically didn’t exist yet, and a 700 x 50c tire nobody wanted to talk about. 

The day after the race I was able to see the actual bikes of both Cole Paton and Brendan Johnston. With their bikes the only thing they were missing versus the prototype I’d seen before were the tires (as they are both sponsored by other tire companies). 

The above photos are a clear visual reminder of just how important it is to get rider feedback. You can be the best engineer in the world but unless you can use the products in these sort of conditions you are just that.. an engineer.

So with that, let’s look at what launched in 2026.

The Revolt Advanced SL

The bike Johnston and Paton raced on is Giant’s first Advanced SL level Revolt, and that matters when you read the numbers below.

Most of what I had eyeballed in Emporia held up in the actual numbers. The geometry is more aggressive. Stack on a medium drops from 586mm to 557mm, reach goes out to 395mm, the seat tube angle gets a full degree steeper at 74.5°, and the head angle is 71.5° with a 50mm rake. Wheelbase on a medium is 1,033mm with 433mm chainstays and 80mm of bottom bracket drop. The flip chip dropout from the old bike is gone and there’s a UDH hanger in its place, so no more long/short clearance game — it’s 53mm max, period. The bike was designed around 45mm as the so-called “magic” number. In a nod to the racing aims of this bike, the GXR Internal frame storage is gone. The bike keeps the proprietary D-Fuse post which means no dropper.

The frame comes in at 839g, down from 990g, with a 385g fork. Giant credits the CNT resin, a one piece front triangle molded with one bladder instead of three, continuous fiber through the junctions, and cold blade cutting of the carbon swatches (392 of them if you’re counting). The Contact SLR XR one piece bar and stem is 295g and replaces the 400g two piece cockpit on the old top model, and it’s got clean routing for SRAM AXS or Shimano Di2, though every build currently ships with SRAM.

The system numbers include the cockpit and the CADEX wheels, which is Giant’s Total Speed System pitch in a nutshell. It was the same with the Propel launch that we covered this year as well. The frame, fork, bar, wheels and tires were designed and developed as one package, and the stiffness and weight claims only apply to the SL 0 build that ships with all of it. The SL 1 and SL 2 get the same frame and cockpit with Giant’s own 50mm CXR 0 wheels, so expect slightly different numbers there.

On aero, Giant’s wind tunnel work has the complete system at 257.58 watts of linear drag versus 271.39 for the old bike, measured across a plus and minus 20 degree yaw sweep, which is a 13.81 watt improvement. Add 2.15 watts of wheel rotating drag and 3.03 watts of tire rolling resistance and the headline number is 18.99 watts of total resistance saved. The frameset by itself is worth 3.72 watts of that. The speed band they tested at is 30 to 45 km/h, which Giant says is where the front of a gravel race actually lives for five to ten hours. Fair enough. It’s still a manufacturer tunnel comparing its own two bikes, so file it to where you file those.

CADEX Max GXR WheelSystem

Launched in conjunction with the the Revolt Advanced SL 0, the wheel is built on the same Max hub and spoke architecture that CADEX has been rolling across its road line that we have covered for a couple of years now, pushed under a new redesigned specific gravel rim. It includes the Carbon Super Aero spokes bonded into a one piece carbon hub flange, hidden titanium nipples, internal spoke tensioning, Dynamic Balanced Lacing to even out tension under pedaling and impact loads, and an R3-C60 hub with a 60 tooth ratchet on a wave spring. It is the same foundation as the Max 40 and Max 50 on the road. The engagement and that dead quiet stiffness are going to feel very familiar.

The rim is where things are very different. It is 50mm deep, and of course its hookless. But unlike the rest of the gravel world, they have stuck with a 25mm internal rim width like the AR 35 Wheel, but went with a Wide Guard 5mm bead that I called an upper and outer flare. This is something that team manager Carl Decker has been asking for years for. CADEX’s explanation is about what you’d expect. A fat, rounded rim edge spreads an impact out and resists pinch flats without adding a lot of weight, and a 25mm bed lets you run a 45 or 50c tire at the pressures you would expect. 

So far all of the performance claims are against CADEX’s own AR 35 gravel wheel. Wind tunnel testing put the Max GXR 4.61 watts ahead of the AR 35 as a system, 3.74 of that in aero drag and 0.87 in rotational drag, across what CADEX calls a broad range of yaw. Rear wheel transmission stiffness is up 24.8 percent and transmission stiffness to weight is up 19.9 percent. Giant’s bike level data compares the new wheel and tire against the old CXR 1 and 40mm GX combo and has rotating drag at 4.86 watts front and 3.64 rear versus 6.09 and 4.56, which is a combined 2.15 watt gain. Different baselines, so don’t go adding the two sets of numbers together.

The Max GXR is one of most expensive wheels on the market at $4,000 in the US (€3,799, £3,499, AU$5,399) as a standalone WheelSystem, and it only comes stock on the Revolt Advanced SL 0.

CADEX GXR Tire

The CADEX GXR Tire is the only piece that both pro athletes didn’t really touch, and the only piece that I have been able to actually ride myself. The 700 x 50c tire on the Emporia display bike was the GXR, and it comes in two sizes, 45c and 50c. The Revolt Advanced SL ships with the 45 on every build. The tire slots in above the existing GX from a fast performance stand point. CADEX hasn’t said whether the GX is going away. My guess is it sticks around and hope it does as I think it’s a better tire for every day use. Think of it as your high milage running shoe. It’s got a little more support and you’re not going to slide as much in the corners on the downhill during your zone 2 workouts. 

The GXR is what it’s supposed to be, a racing tire. It’s got a tight fast rolling center tread, reshaped shoulder knobs that are shallower than the GX while sticking with the 170 TPI casing that CADEX calls its Supple Race Casing. Protection is a two layer deal, Race Shield+ under the center tread and X-Shield in the sidewalls, which CADEX describes as bead to bead coverage. The compound is their GX-S dual compound, harder down the middle and softer on the shoulders. Other features: Kevlar folding bead, tubeless, hookless compatible, 25 to 50 psi.

So far on my rides, the tire is noticeably faster but it’s not something that I would personally buy for around my neck of the woods on the daily. It’s a little too fast for this part of the world. It lacks the extra cornering grip that I want to have on the tight single track that I ride 95% of the time around my house. But with that said, this tire would be fine on a midwest course that was mostly flat and fast. I like the idea of being able to have the same feel at my disposal though. So if I was a die hard user I would train on the GX’s and depending on the course race on the GXR

The one hard number CADEX gives us is rolling resistance. On their own drum the GXR 45c tests at 30.91 watts per wheel against 32.41 for the GX 40c, so savings of 1.52 watts per tire and 3.03 per bike at the same pressure. That’s the 3.03 watts Giant folds into the Revolt’s 18.99 watt total. Keep in mind that’s a 45mm tire going up against a 40mm tire. Giant also claims the 45mm GXR has the same aero drag as the narrower 40mm GX, which they put down to the smoother, less blocky tread. These claims haven’t been tested by any other 3rd party that I have seen yet. 

A weight of 490g for a 45c race tire with real sidewall protection is competitive but not remarkable, and the pressure range makes sense for a 25mm rim. The interesting one to me is the 50c, which is the size that was on the prototype at Unbound. The bike officially clears 53mm, so a 50 is in play on the production Revolt, and I’d bet that ends up being the size a lot of people actually ride at something like Unbound or Big Sugar.

CADEX Max XC

As we now know 50% of the Life Time Grand Prix is mountain bike racing. And that 50% starts at Leadville every year, which is when this wheel first appeared on bikes. Later Johnston’s second at Chequamegon on September 19 came on an Anthem Advanced SL with what Giant would only call a prototype CADEX WheelSystem. CADEX announced that wheel as the Max XC on October 5, their first mountain bike product. Giant put it on a limited edition Anthem Advanced SL SE a couple of days later, and on October 11 Paton won Little Sugar on an Anthem wearing production Max XCs. So it was pretty cool to see a Grand Prix win within a week of product launch.

The CADEX Max XC Wheelsytem is the Max architecture again, with bonded carbon spokes into carbon hub flanges, now in a 29er Boost package with a 22mm deep hookless rim, 30mm internal and 40mm external, the 5mm Wide Guard bead, ceramic bearings and a 120 tooth helical bevel ratchet. CADEX claims a total weight of 1,247.6g with tape and valves, which is light but not class leading, and they know it, because the launch material spends two full pages on a head to head against the Roval Control World Cup — same seven lab tests, measured by CADEX’s lab.

The Roval is a quarter kilo lighter and noticeably more vertically compliant, and in XC those are not small things. The CADEX wins everywhere stiffness under pedaling torque matters, and it takes nearly twice the crushing load before the rim gives up. CADEX calls the compliance gap a deliberate trade for durability. Fair enough, and I’ll give them credit for printing the three datapoints they lose, but the weight line is the one the XC crowd is going to stare at. Paton’s win and Johnston’s Chequamegon podium should tell you the wheel is plenty fast enough. The other thing that we also always have to keep in mind is that you can’t win a race if you don’t finish so CADEX is clearly chooses the battle with what markers they want to be at the top of the list on.

The CADEX Max XC Wheelsystem is also one of the most expensive wheels on the market at $4,000 (€4,200, £3,500). The Anthem Advanced SL SE it comes on is the fourth generation Anthem that launched last November, the same frame Alan Hatherly rode to the 2025 XCO world title, with 120mm of FlexPoint Pro travel, a flip chip, room for two bottles, the integrated Contact SLR XC cockpit, SRAM XX SL Transmission with a power meter, RockShox Flight Attendant, custom colored SRAM brake hardware and a Stormfire paint job that is either spectacular or a lot, depending on your taste. Giant has it at €14,000 and £11,999 with availability from November.

The Team on the Ground

The Gravel Collective, as Giant calls its gravel program, is led by team manager Carl Decker, a 51-year-old native Oregonian who lives in Bend. Decker spent more than 20 years on the Giant Factory Off-Road Team before sliding over to run the gravel squad, and his own résumé is hard to top: five Downieville All-Mountain titles, a singlespeed world championship, and seven trips to UCI Worlds with the US team. He also races rally cars on the side.

On the bike, the Collective is anchored by two riders. Cole Paton, 28, hails from Cashmere, Washington. He won four collegiate national championships at Fort Lewis and has three US XC marathon titles. Until this year, though, he had finished top five in the Grand Prix three times without ever winning a round. That kind of record gets you called “consistent” when what you really want is a trophy.

His teammate Brendan Johnston, known as “Trekky” to anyone who follows Australian racing, is 34 and from Canberra. Riding for Giant-SRAM, he has collected two Australian gravel national titles and seven Australian marathon titles. In 2024, he and Paton became the first two riders from the same bike brand to both finish in the series’ top five in the same year. And this January, Johnston rode across Australia in eight days.

In speaking with Carl, it became clear that the riders’ history together over the last three seasons gave them a real role in development. They were able to give feedback on geometry, compliance, and handling at race speeds, and they tested concepts in real-world conditions. Looking at the timeline of when these riders went from prototypes to production launches shows how that process played out.

That timeline also includes one rider from outside the Gravel Collective. Melisa Rollins races for the Liv Racing Collective, but she was supported just as closely by Carl and others under the Giant umbrella. She raced exclusively on custom Liv frames, the Pique and the Devote, which is why she appears alongside Paton and Johnston.

During the season while Giant and Cadex were not talking about these new products in the open they also weren’t really hiding them either. The gravel package raced Unbound and the mountain bike wheel raced Leadville and Chequamegon and a national championship before CADEX would officially talk about it.

How Did the Racing Go?

Here’s how the Life Time Grand Prix broke down. Six races, best five count, three on gravel and three in the dirt. The Grand Prix is invite only, so when somebody from outside the series like Mads Würtz Schmidt or Tobias Kongstad wins, the series points start one spot back. Where the overall finish and the series finish are different I’ve listed both. Results come from the Life Time Grand Prix athlete pages for Johnston and Paton.

Sea Otter was pretty forgettable for both of them and success really didn’t start until Emporia.

Unbound 2026 was a mud year. Rain, wind, riders on the ground at mile 11, and a lot of the big names heading home early. Johnston got tangled up in a string of early mishaps, chased back on to the front group more than once, missed the three rider move that decided the race, and then rode the last couple of hours mostly by himself to finish fourth, 22 minutes behind Mads Würtz Schmidt. Career best for him at Unbound and second among the series riders. He did it on the prototype Revolt and the prototype CADEX wheels, the same stuff I had been poking at that weekend, and in Giant’s own write up he called the bike “outstanding from start to finish.”

Leadville was two solid top tens at altitude on a course that got rerouted around this summer’s wildfires. Paton sixth, exactly five minutes behind Swenson, and Johnston seventh, both on the Anthem Advanced SL. Johnston’s previous Leadville results were 19th, 14th and a DNF.  He said on his IG account post race that he was very happy with the result and was looking forward to trying it again in 2027.

Chequamegon is where the second half of this story shows up. Johnston was second on the 40 mile point to point from Hayward to Cable, 58 seconds behind Matthew Wilson and two seconds in front of Keegan Swenson, and Giant’s reportmentioned his Anthem was built up with a prototype CADEX WheelSystem. That wheel is the Max XC, and CADEX didn’t announce it until October 5. Paton was ninth, 1:19 off the win. He later admitted he went way to early in the chase group and just end up getting crushed towards the end and missed those higher spots. A week later Johnston flew home and won his seventh Australian XC marathon title in Canberra on the same setup.

Little Sugar on October 11 was Paton’s day. He attacked with about 24 miles to go on the Back 40 trail and rode in alone in 4:06:37, 1:12 up on Bradyn Lange, with Andreas Seewald third and Johnston fourth after a rough first hour. First Grand Prix win for Paton in five years of trying, and the Anthem was on production Max XC wheels (the wheel had been a product for all of six days) with a custom eagle paint job for his national title.

That set up Big Sugar, 101 miles through the Ozarks, with Johnston in a spot to take the overall. It came down to a nine rider sprint. Kongstad won, Mārtiņš Blūms was second, Paton third, Johnston seventh, and all of them got the same time give or take a second. Swenson flatted early, finished 24th, and still won the series by one point, 123 to 122. Points go two per spot at that end of the sheet, so one more place in that sprint and the title is Johnston’s. He said afterward that he raced to win rather than to protect a position, and that he spent 400 hours just traveling to Grand Prix events this year. Paton’s third moved him from fifth to fourth overall.

Closing Thoughts

Pretty dang big year for the Giant Family and not to mention LIV as it had the same prototype frames that launched as well. The story is still the same though while CADEX lives on its own as a very premium product in the marketplace it’s nice to see some of the merging of products with the Giant line. The thing I really liked about this year was personally seeing the rider feedback get realized in some overall victories and podiums. Companies work hard, athletes work hard and it’s always awesome to see hard work payoff and the team that made this year happen have lots to celebrate.

According to Carl and Ewan (Cadex product manager), the team and riders suffered zero product faults all season long and had a reduction of flats during the year by over 60% from last year. They credit that success to the product team and what will now be available for public use.
