Canyon announced the Lux Trail on July 14 as a 2027 model, and it takes over the job the Neuron used to do in the range. 125mm rear, 140mm front, 200g lighter than the bike it replaces. The number that stands out in the chart is not the travel though. It is the head angle: 64.8 degrees on a downcountry bike, when most of the category still sits between 65.5 and 66.5.
Two other things in the table are worth more attention than Canyon’s press material gives them.

The XS and the S share a front end
Look at the stack row and then the head tube row. XS and S are both 603mm of stack on a 93mm head tube. Identical. The only thing separating the two sizes at the front of the bike is 20mm of reach.
That matters for the rider most likely to be choosing between them. Someone on the XS is not getting a proportionally scaled bike, they are getting the S with a shorter front centre. Bar height relative to the bottom bracket is the same on both, so if the S feels too tall at the front, the XS will not fix it. The fix is spacers and a bar with less rise, not a size down.
Canyon is not unusual in doing this. Head tubes come in a limited number of lengths and the smallest sizes tend to bottom out against the shock and the front triangle. It is worth knowing before you order a bike you cannot throw a leg over first, which is how most Canyons are bought.
The rear centre barely moves while the front grows 80mm
Chainstays take two values across five sizes: 435mm on XS, S and M, then 440mm on L and XL. Reach over the same range goes from 410mm to 490mm.
Run the ratio and the balance of the bike shifts considerably. On the XS the rear centre is longer than the reach, 435 against 410. On the XL the reach is 50mm longer than the rear centre, 490 against 440. The XS rider sits proportionally further back between the wheels than the XL rider does, by roughly 18 percent when you compare the two ratios.
The practical version: the XL will feel more weight-forward and will want more deliberate work to keep the front wheel tracking on a steep climb, while the XS will feel like it wants to loft the front more readily. Neither is wrong. It is the normal consequence of sizing the front of a bike five ways and the back of it twice, and it is the single most common compromise in the category.
What a 64.8 degree head angle is doing on a 125mm bike
Pair it with a 38mm bottom bracket drop, which is generous, and a wheelbase that reaches 1,258mm in XL, and the picture is a bike set up to be ridden harder than its travel suggests. For reference, plenty of 140mm trail bikes from three years ago ran steeper head angles than this.
The seat angle row is the counterweight. 76.4 degrees on XS easing to 76.0 on XL is on the slack side of current practice, and it barely varies with size, so taller riders end up further behind the bottom bracket than they would on a bike with size-specific seat angles. On a 125mm bike that will be pedalled uphill a great deal, that is the number most likely to be felt on a long day.
Where it sits
Put it next to anything else in the bike geometry comparison calculator and the Lux Trail reads as a short-travel bike wearing trail-bike angles. The comparison worth running is against a 140mm trail bike rather than against other 120mm race bikes, because the head angle and bottom bracket drop have far more say in how a bike behaves than the shock stroke does.
What the chart cannot tell you is how 125mm of rear travel copes when the front end writes cheques at 64.8 degrees. That is a question for a long-term test, not a geometry table.
