When the Crux 5 launched in May, it was the bike everyone else had to answer. Five months later, most of them have. Canyon released a new Grail with even more clearance, Ridley’s Kanzo Fast 2.0 just won BikeRadar’s Bike of the Year, BMC reworked the Kaius, and X-Lab started selling a 55mm-clearance carbon gravel bike for about a quarter of the S-Works price.

I ride the previous-generation Crux, so I have a horse in this race. I haven’t ridden every bike below. This is a read of the specs, prices and the reviews from people who have, with my own experience as a Crux owner where it applies.

Quick answer: No single bike beats the Crux 5 at everything, but three beat it at something specific. The Ridley Kanzo Fast 2.0 has more clearance and more versatility. The Canyon Grail CFR gets you a SRAM Red build for $5,000 less. And the X-Lab GT8 is the value pick by a mile. The Crux 5 is still the best all-rounder if you value low frame weight, a threaded bottom bracket and being able to walk into a shop.

X-Lab GT8 55 mm 8.78 kg complete (M) 1x or 2x $3,199 complete, frameset $2,000

Claimed numbers, not my scale. Frame weights in particular are measured differently by each brand, so treat that column as a rough ranking, not a lab result.

Where the Crux 5 Still Wins

Frame weight. At 789 grams for the S-Works frame, nothing else in this group with 50mm+ clearance is close. The Grail CFR frame is 200 grams heavier. You feel weight most on long climbs and when you’re lifting the bike over things, and if your gravel looks like mine in Southern California, there’s a lot of climbing.

The boring stuff that matters. The Crux 5 keeps a threaded BSA bottom bracket and a UDH dropout. The Grail moved to PF86 press-fit. Canyon has its reasons, but after years of creaky press-fit bottom brackets on other bikes, I’ll take threads every time. UDH also means any of SRAM’s Full Mount XPLR derailleurs bolt straight on, which I go into in this UDH frame guide.

The lineup. Seven price points from a $3,999 GRX Sport to the $13,999 S-Works, all on the new frame shape, plus framesets at $3,499 and $5,799. And you can test ride one at a shop this weekend. That counts for something on a bike you’ll put real miles on.

Where it’s weak: reviewers keep saying the front end is firm for a gravel bike, even with the new Terra cockpit, and the stock Tracer tires lose grip on steep, dusty descents. The tires are an easy fix. On my old Crux I ran a 2.1" Schwalbe Thunder Burt up front (clearance test here), and with 55mm of room the Crux 5 makes that kind of swap easy. And the S-Works price is hard to defend when you look at what Canyon charges.

Ridley Kanzo Fast 2.0: The One That Might Actually Be Better

If any bike here beats the Crux 5 outright, it’s this one. Ridley went from 42mm to 58mm of clearance, which fits a 29 x 2.3" mountain bike tire. It clears a 56-tooth chainring for riders who want big gears on fast courses. It takes full mudguards with tires up to 50mm, which the Crux 5 can’t do at all, and it has internal down-tube storage. BikeRadar named it their overall 2026 Bike of the Year and called it “well-priced” and “very quick everywhere.”

Ridley’s own numbers are worth reading carefully. They claim 13 watts saved over the old Kanzo Fast with a rider at 36 km/h, but they also say a 55mm tire costs about 6 watts of aero drag compared to a 38mm one. Their argument is that lower rolling resistance on rough gravel more than pays that back. I think that’s right for chunky courses and wrong for smooth ones.

The catch for US buyers is availability. Pricing is only listed in euros so far (€5,499 for Rival XPLR, €6,999 for Force, €11,699 for Red), and it’s electronic 1x only. If you can get one and your riding is rough, wet or long, this is the bike I’d look at hardest.

Canyon Grail CFR: Same Idea, Much Better Value

The new Grail is the Crux 5’s closest match in philosophy: aero, 1x only, big tires. It clears 57mm, two more than the Crux, and Canyon’s wind tunnel testing put it ahead of the Áspero-5 and Rose Backroad FF. I covered the launch in detail in Canyon’s New Grail Is Here, and It Finally Fits Real Tires.

The real difference is price. The SRAM Red XPLR Grail CFR is $8,999 at a claimed 7.9 kg. The S-Works Crux 5 with Red XPLR is $13,999. That $5,000 buys a full set of nice wheels and a season of race entries. The S-Works is lighter, but the Crux 5 S-Level, at a claimed 7.7 kg and $10,499, is the fairer comparison, and the Grail still undercuts it by $1,500.

What you give up: a heavier frame, a press-fit bottom bracket, and direct-to-consumer buying, so no test ride and you’re on your own for setup and warranty logistics.

BMC Kaius 01: Fixed, But Expensive

BMC’s 2027 Kaius goes to 52mm of clearance, drops the front derailleur mount for 1x only, and fixes a lot of what people disliked about the first version. BikeRadar’s reviewer gave it 4 out of 5, but noted it’s firmer over rough ground than the best in this group, and said he’d personally buy the Kaius 01 Two at $8,999 over the $12,999 Red build. At 7.97 kg for the top model, it’s heavier than both the S-Works Crux and the Red Grail while costing about as much as the S-Works. Unless you love how BMCs ride, it’s hard to pick over the Grail or Crux.

Trek Checkmate SLR and Cervélo Áspero-5: Fast, But Falling Behind on Tires

Both are excellent bikes on smooth, dry gravel. The Checkmate SLR shared a German magazine’s race gravel test win with the previous Grail, and Trek claims it’s almost six minutes faster than its own Checkpoint SLR over Unbound at 200 watts. The Áspero-5 is one of the most aero frames in gravel.

Both top out at 45mm, though. A year ago that was plenty. Now that the Crux, Grail, Kanzo and even a $3,199 X-Lab clear 55mm or more, it’s a real limitation if your races or rides get rough. If your gravel is fast and dry and you want something that rides like a road bike, either is great. For everyone else, the clearance gap is hard to ignore. The 2026 tire clearance chart has more frames if you want to compare further.

X-Lab GT8: The Value Wildcard

At $3,199 complete, the GT8 comes with Shimano GRX Di2, carbon wheels and a power meter crankset, and it clears 55mm, the same as the Crux 5. Bikerumor called it “a solid, modern gravel bike priced to move.” The tradeoffs: it’s heavier, at a claimed 8.78 kg, it isn’t as aero, and nobody knows yet how these frames hold up long term. The bare frameset is $2,000. If you’ve read the backstory on why a factory brand selling direct isn’t new, the GT8 is what that looks like in practice. For a first carbon gravel bike, or a race bike you won’t cry over, it’s the obvious pick.

So Which One Would I Buy?

  • Lightest, best-supported all-rounder: Crux 5, and the Comp at $4,499 is the sweet spot. You get the same FACT 10r frame shape as the Expert and Rival XPLR shifting.
  • Most bike for the money at the top end: Canyon Grail CFR with SRAM Red at $8,999.
  • Most clearance and versatility, if you can get one: Ridley Kanzo Fast 2.0.
  • Best value, period: X-Lab GT8 at $3,199.
  • Smooth, fast gravel only: Trek Checkmate SLR or Cervélo Áspero-5.

If I were replacing my Crux today, it would come down to the Crux 5 Comp and the Kanzo Fast. I’d lean Crux for the threaded BB, the weight and being able to get it serviced locally. But if Ridley lands in the US at prices close to the euro numbers, that could change my answer.

Whatever you pick, the frame matters less than the tires you put on it. My picks for mixed pavement and dirt are a good place to start. If you’re wondering whether one of these could also replace your road bike, I made that case in Crux 5 vs Road Bike.
