Compare ride character, intended rider, geometry, and fit. Add your measurements to see which bike suits you better and which size to choose on each.
Fit verdict: the frame positions are close, a few millimetres apart. The frame alone will not decide this; use your measurements to see which size and setup gets nearer to your position on each bike.
BMC URS 01 TWO: all-road geometry. Canyon Grail CF SLX 8 AXS: race geometry.
These two split on internal frame storage, bottom bracket, maximum tyre clearance; the sourced values are below. What each difference means for your size, your setup and the riding you describe is in the full comparison.
In-frame storage means tools and a tube ride inside the bike instead of in your jersey or a saddle bag, and it changes what you carry on every ride.
A threaded bottom bracket is simpler to service and less prone to creaking; press fit saves weight and allows a wider shell.
Tyre width decides which surfaces stay comfortable. A few millimetres is the difference between staying on tarmac and being able to drop onto gravel without a second bike.
Canyon Grail CF SLX 8 AXS is the dearer of the two, going by the cheapest build you can buy of each; BMC URS 01 TWO starts lower.
Subjective findings from independent tests on stock or near-stock builds. Tyres, pressure and size change how a frame feels.
We compare differences at frame and model level. Components, current price, and availability depend on the exact build and seller.
Start with the decision you are making. We will ask only for the details needed to answer it.
Step 1/1
Your answer decides which questions follow and what the result focuses on.
The matched frame measurements differ by only a few millimetres, so stem and spacer choices can matter more than the frame.
Typical difference across matched sizes: frame front height 7 mm, forward length 6 mm.
For a personal answer, the fit-and-size path uses your measurements to show only the relevant frame sizes. The full chart remains available as a reference.
See the closest size matches and the differences in stack, reach, and riding position.
Stack: 18 mm taller
Reach: 18 mm shorter
Stack: 4 mm taller
Reach: 21 mm shorter
Stack: 10 mm taller
Reach: 8 mm longer
Stack: 8 mm lower
Reach: 6 mm longer
The same size label can create a different position on each frame. Stack and reach are one part of the decision; the personalized comparison connects them to your body and each bike’s ride character.
