CrossWorx lists 79° as the seat tube angle on all four sizes of the LITE MK2, and Pinkbike’s launch coverage called it “the steepest of any bike in this travel bracket”. That number alone would be worth a look. What makes the bike genuinely strange is what sits at the other end of the frame: a 66° head angle, which in 2026 reads as conservative to the point of contrarian for a 135mm trail bike running a 140 to 150mm fork. Announced on 9 September 2026, the MK2 is the second generation of the German brand’s alloy trail platform, and it is the rare modern bike whose geometry sheet you have to read twice to be sure it is not a typo.
The published chart
This is the manufacturer’s own table from the CrossWorx LITE MK2 product page, reproduced in full, in millimetres and degrees. The final column is the delta for the mullet (29″ front, 27.5″ rear) configuration, which CrossWorx publishes as an offset rather than a separate chart.

Travel is 135mm rear from a 210x55mm shock, with a 140 to 150mm fork. The chart’s 551mm axle-to-crown figure corresponds to the 140mm setting; Pinkbike notes the head angle relaxes to roughly 66.5° with a 150mm fork fitted, which is the expected half-degree per 10mm of fork.
The chainstay question, settled
Pinkbike’s write-up gives chainstay length as 435 to 455mm, while CrossWorx’s chart lists 455mm across S, M, L and XL. That looks like a contradiction and has been read as one, but it is not, and it is not adjustable dropouts either.
The 435mm figure is the mullet configuration. Running a 27.5″ rear wheel pulls the rear axle forward in the same swingarm, and CrossWorx publishes the resulting numbers as a set: 435mm chainstay, BB drop falling from 40mm to 28.5mm, wheelbase down by 20mm. The Dutch coverage at Trail Addicts states it plainly: the mullet setup reduces the chainstay to 435mm against 455mm with the 29″ rear. Pinkbike’s own figures list it the same way, 455mm for 29″ and 435mm for 27.5″, and the range in the summary line is simply both wheel options collapsed into one span.
So: 455mm on every size in full 29, 435mm only if you fit a 27.5″ rear wheel. There is no flip chip, no size-specific rear centre, and no dropout adjustment. If you want the short back end you accept the lower BB drop that comes with it, and vice versa. That matters because the two setups are not close: 40mm of drop with a 455mm rear is a stable, planted bike, while 28.5mm and 435mm is a noticeably livelier, higher one. These are different bikes to ride, not a trim option.
What 79° actually buys
Seat tube angle is a lever on where your hips sit relative to the bottom bracket when the post is extended. Steepening it moves the saddle forward and, in effect, shortens the effective top tube while lengthening the front centre you are sitting behind. The practical consequence on a climb is weight transfer: more mass over the bottom bracket and the front wheel, less hanging off the back.
At 79° the LITE MK2 is roughly one to two degrees steeper than most current 135mm trail bikes, which cluster around 77 to 78°. On a steep fire road that difference is worth real front wheel weighting; the wandering, lifting front end that plagues slack-seated long-travel bikes largely disappears, and you can keep pedalling seated on gradients where you would otherwise be perched on the nose of the saddle. It also tends to improve pedalling biomechanics for riders with limited hip flexion, because the hip angle opens up when the saddle comes forward.
The trade-offs are honest ones. A very steep seat angle shortens effective top tube more the higher your saddle goes, so tall riders on long posts feel it most. Seated pedalling on flat ground can feel cramped and a touch perched, with more weight on the hands. And because seat angle is measured from the actual saddle position at a given height, the effective figure gets steeper still as the post comes up. CrossWorx’s 12mm seatpost offset (listed as J on the chart) is part of how they arrive at the published number, so the layback of your own post materially changes what you actually ride. Fit a zero-offset dropper head and it gets steeper again.
Why pairing it with 66° is unusual
The prevailing orthodoxy runs the other way. Since roughly 2019 the industry has coupled steep seat angles with progressively slacker head angles, the logic being that a forward seated position needs a long front centre and a slack fork to stay safe on descents. A 2026 trail bike at 135mm rear travel typically sits at 64.5 to 65.5°.
CrossWorx has gone steep at both ends. 66° with a 551mm axle-to-crown fork gives a shorter front centre and quicker steering than the class norm, and the 40mm BB drop keeps the bike low without relying on a slack front to provide stability. Put those together and the result is a bike biased towards direction changes and tight, technical terrain rather than straight-line speed on open steeps. It is closer in spirit to what the class looked like in 2020 than to what most brands sell now, and that is clearly deliberate: CrossWorx’s previous LITE 290 was reviewed as a poppy, playful bike rather than a plough, and the MK2 doubles down on that character rather than chasing enduro-adjacent numbers.
The 455mm chainstay is what keeps the whole thing coherent. It is long for a 66° bike, and it offsets the short front centre by keeping the rider’s mass reasonably centred between the axles. Without it, a 66° head angle and a 505mm reach would put an XL rider uncomfortably far forward on steep terrain. The combination that looks eccentric on a spec sheet, steep head angle plus long rear, is actually a fairly rational weight-distribution argument.
Digressive to progressive, and what your shock has to do
The MK2 runs a linkage-driven single pivot on a 210x55mm shock. Pinkbike describes the previous LITE as having a digressive curve up to sag that turned progressive later to prevent harsh bottoming; the MK2 is now consistently progressive through the stroke.
A digressive-then-progressive curve is a specific compromise. Digressive early means leverage ratio falls as the shock compresses in the first part of travel, which gives a supple off-the-top feel but makes mid-stroke support depend heavily on the damper rather than the linkage. Riders often end up chasing that support with compression damping or extra air pressure, both of which cost small-bump sensitivity.
Consistently progressive means leverage falls steadily throughout. The wheel rate rises the deeper you go, so support builds mechanically rather than hydraulically. In practice this does three things. First, it widens the useful range of shock tunes, because you are no longer leaning on the damper to hold the bike up in its mid-stroke. Second, it makes coil shocks viable in a way a digressive-early curve rarely does, since a coil’s linear spring rate needs the linkage to supply the ramp. Third, with an air shock you can usually run fewer volume spacers and a slightly lower pressure than the outgoing bike, gaining sensitivity at the top while keeping bottom-out resistance. On a 135mm bike on a 55mm stroke, that is a meaningful gain: short-travel bikes have the least margin for error in how they use the last 20mm.
Anti-squat behaviour on a linkage-driven single pivot is dominated by main pivot height relative to the chainline, and CrossWorx does not publish an anti-squat curve, so this article will not guess at one. The steep seat angle already handles a good part of the pedalling platform question by moving the rider forward; a bike that does not need to rely on high anti-squat to pedal well is generally the better-behaved bike under power over rough ground.
Where a small German brand sits
CrossWorx is a small operation building alloy frames in Germany, welded and assembled in-house. That is a different proposition from the mass-market trail bikes this site usually measures. The comparison is not really on spec-per-euro, because a Canyon or a YT will win that fight every time. It is on the things volume manufacturing makes hard: unusual geometry decisions that would never survive a focus group, serviceable alloy construction, and frames that can be repaired rather than replaced.
Be careful with the pricing, because CrossWorx publishes two sets of numbers. The consumer-facing figures are €2,499 for the frame and €4,499 to €8,845 for complete builds, all including VAT. The product page also lists ex-VAT figures, roughly €2,100 for the frame kit and about €3,644 for the cheapest complete, and those are the ones you will see quoted by accident. The ex-VAT numbers are relevant if you are buying from outside the EU; for a German or EU buyer, the €2,499 and €4,499 figures are what you pay. Reported weights are 3.7kg for a medium frame and 14.3kg for a complete large, which is respectable for alloy and unremarkable against carbon.
Sizing, and specifically for tall riders
The reach ladder is 415, 445, 475, 505 in clean 30mm steps, which is unusually tidy and makes size selection legible. Stack does not step with it, though: S and M share 625mm, then 634 and 643. That means the M has the lowest stack-to-reach ratio in the range and will feel the most aggressive of the four, while the XL’s 643mm stack is generous by class standards.
At 6’4″, the XL is the right size and it is not a marginal call. 505mm of reach with a 643mm stack and a 1282mm wheelbase is a properly proportioned large bike, and the 79° seat angle is most useful precisely at that height, where a slacker seat tube would put your hips well behind the bottom bracket with the post at full extension. The 465mm seat tube with 288mm of maximum insertion will take a 210mm dropper comfortably, which is the figure that actually decides whether a tall rider can use the bike.
Two caveats for tall riders. The effective top tube of 618mm is long, but the steep seat angle means it will feel shorter seated than the number suggests, so budget for a slightly longer stem or a saddle set further back if seated pedalling feels cramped. And a 455mm chainstay behind a 505mm reach is proportionally shorter than it is on the size S, where 455mm sits behind 415mm; with the rear centre fixed across sizes, the XL rider ends up further forward in the wheelbase than the S rider. That is the standard penalty of a non-size-specific rear end, and it argues for the full 29 setup rather than the mullet if you are tall, since the mullet’s 435mm would push the balance further still.
For riders in the 175 to 187.5cm band, the L at 475mm reach is the obvious pick and the best-balanced size in the range. Anyone between sizes should size down if they ride tight, technical terrain (the 66° head angle already rewards that) and up if they mostly ride fast and open.
