The Third Canyon Grail: 57 mm Tyres, One Chainring and a Lower Front End, Explained

Summary

• Canyon launched the third generation Grail in September 2026. Tyre clearance goes from 42 mm to 57 mm, front and rear, with 45 mm Schwalbe G-One tyres fitted as standard.
• The frame is single chainring only. Canyon says a front derailleur would have capped rear clearance at 50 mm.
• Three frame grades. Raw size M frames weigh 989 g in CFR, 1,095 g in CF SLX and 1,128 g in CF, per BikeRadar.
• Six builds from €2,499 to €8,000. The CFR AXS is claimed at 7.9 kg for €8,000, £7,600 or $8,999.
• Every aero figure is Canyon's own, measured at 35 km/h. No independent wind tunnel test has been published.

What the third Grail is

The first Grail is the one people remember, for the double decker handlebar that split opinion. The second dropped that idea and settled into a conventional gravel race bike with 42 mm of clearance. The third keeps the category and changes the constraints.

Two decisions define it. The frame takes a 57 mm tyre, roughly a 2.25 inch mountain bike casing. And it accepts one chainring only. Everything else, from the chainstay shape to the bottom bracket standard, follows from those two.

Canyon fits 45 mm tyres as standard and quotes seven sizes, from 2XS to 2XL, for riders between 158 cm and 204 cm, per BikeRadar.

The 57 mm clearance and why the front derailleur went

Canyon is unusually direct about the trade. Keeping 2x compatibility would have limited rear clearance to 50 mm, so the front derailleur was dropped and the driveside chainstay rebuilt as a solid, slimmer section, per gravelpassion and brujulabike. The bottom bracket moves to PressFit PF86 to widen the chainstay junction.

That buys 57 mm with the ISO safety margin included, at a 435 mm chainstay across every size. The cost is gearing. A 1x13 cassette covers a similar range to a 2x, with bigger steps between sprockets. GRAN FONDO also found the stock 40T chainring conservative for flat racing.

Aero: what Canyon measured and against what

Canyon tested in the GST tunnel at Immenstadt at 35 km/h, with a dynamic mannequin and yaw sweeps to plus or minus 20 degrees. Brujulabike published the full set of figures.

Read the table as Canyon's own protocol, because that is what it is. Two things stand out anyway. The gap to the two closest rivals is under a watt, which is inside the noise of a tunnel run. And the new frame on a 55 mm tyre is still ahead of the old frame on a 40 mm tyre. That second line is the real claim: the frame pays for the wider tyre.

BikeRadar quotes the headline as up to 5 W against the gen 2 on 40 mm tyres.

Geometry: lower stack, longer wheelbase

Figures from GRAN FONDO's review of the CF SLX 8 AXS. Against the previous Grail, stack drops 15 mm while reach is held, the wheelbase grows about 10 mm and Canyon fits shorter stems, per BikeRadar. Trail is 69 mm in the middle sizes and ranges from 67 mm to 90 mm across the size run, per brujulabike.

The short version: a lower, longer front end than the bike it replaces, with the stability recovered through the wheelbase rather than the stack.

Builds and prices

Prices per BikeRadar and brujulabike. The €2,499 bike is the interesting one: a carbon frame, a carbon Canyon Pace bar and carbon Canyon GR 50 CF wheels at that price is not normal. The compromise is a mechanical groupset and 9.2 kg.

The GR 50 CF wheelset is new. It runs a 50 mm rim, 27 mm internal and 38.5 mm external width, hookless, on DT Swiss 350 hubs, at a claimed 1,675 g a pair and €999 sold separately. Tyre compatibility is quoted from 35 mm to 60 mm.

The cockpit is Canyon's Pace system: 50 mm of width and 20 mm of height adjustment, in 15 configurations, without cutting the steerer. The new Control Drops flare 17 degrees in widths of 370, 395 and 420 mm. The VCLS Aero seatpost is claimed at 25% more vertical flex than a rigid post.

What Canyon has not published

No maximum chainring size, which matters if you want 50T or larger on fast courses. No per size stack and reach table on the product page, which is why the numbers above come from a review. Down tube storage is limited to CFR and CF SLX, and the DEFEND mudguards fit CF SLX and CF but not CFR.

The independent evidence so far is one review. GRAN FONDO weighed the CF SLX 8 AXS at 8.69 kg in size S with stock tyres. It called the DT Swiss GRC 1400 wheels heavy enough to dull acceleration. Its verdict placed the bike with ambitious racers and ultra endurance riders rather than with climbers chasing weight.

The new Grail or the pre-owned alternative

If your calendar has long, rough events and you already run 50 mm tyres, the third Grail is built for exactly that. If you race fast European gravel on hardpack and white roads, a 45 mm tyre is still the quick choice, and a second generation Grail carries it without complaint.

Three checks before buying either. Whether you actually want a single chainring for the next five years. Whether the lower stack suits your position, since the integrated bar limits how much you can put back. And the wheels, because a 45 mm tyre wants a 25 mm internal rim or wider.

The Canyon Grail collection lists the Grails at Bikeroom, and the wider Canyon collection covers the road and mountain range. The gravel category has the alternatives, and the pre-owned gravel collection is where the previous generation sits. For the two bikes that launched alongside it, see the Ridley Kanzo Fast 2.0 and the Factor Elara. A colleague is preparing a wider explainer on the 2027 gravel race class in this same batch.
