Sixty-four degrees on the XS, sixty-five on the XL. That single line in the Litespeed Pisgah’s geometry chart is the most interesting thing about the bike, because it runs directly against how almost every brand doing size-specific geometry has handled the front end for the past decade. The convention is to hold the head angle constant across sizes, or to slacken the big frames slightly to settle down a long front centre. Litespeed steepens it. The smallest Pisgah is the slackest bike in the range and the largest is the steepest, and the company has not published a word explaining why.
The Pisgah was announced on 19 August 2026 as Litespeed’s first dedicated trail bike: a titanium hardtail built around a 150mm fork, clearance for a 29 x 2.6″ tyre, a T47 threaded bottom bracket, and a UDH rear end with an optional sliding titanium dropout. Base price is $6,999 with Shimano XT Di2, a Fox 36 Factory Grip X and Industry Nine 1/1 Sector V2 wheels, with custom configuration available direct.

Litespeed’s rider height brackets: XS 152 to 165cm, S 162 to 174cm, M 174 to 180cm, L 180 to 192cm, XL 189 to 198cm.
Reading the inverted head angle
Fork offset is constant at 44mm across every size, which is useful because it means all of the trail variation comes from the head angle and nothing else. Trail runs 137mm on XS, 133mm through S, M and L, and 129mm on XL. Wheel flop, the product of trail, the sine of the head angle and its cosine, works out at roughly 54.0mm on XS, 51.7mm on the three middle sizes and 49.4mm on XL. The steering gets progressively lighter and quicker to initiate as the frame gets longer.
Now look at where the mass sits. Chainstay length is fixed at 445mm across the whole range while front centre grows by 113mm from XS to XL. Expressed as a share of wheelbase, the front centre accounts for 62.3% of the XS, 65.2% of the L and 65.5% of the XL. The rider on a big Pisgah is sitting proportionally further behind the front contact patch than the rider on a small one, which is the unavoidable consequence of not scaling the rear end. A front wheel that is further away and less weighted responds more slowly to a given bar input, because the yaw moment arm is longer and the tyre has less normal force to work with. Cutting trail by 4mm and flop by roughly 2mm is the cheapest way to hand some of that response back without touching reach or rear centre.
Run the same logic at the small end and it holds up better still. The XS has a 1156mm wheelbase and a 720mm front centre, and a 152cm rider sits high and forward relative to a 29″ front wheel. That is a bike with a genuine over-the-bars problem and a nervous, twitchy front end waiting to happen. Adding half a degree of slack and 4mm of trail is a stability and safety measure, not a fashion statement.
Put plainly: this looks like an attempt to keep the steering feel consistent across sizes rather than the angle. That is a defensible engineering position and arguably a more rigorous one than the industry default. It is also entirely my reading. Litespeed’s own marketing talks about size-specific tubing and “balanced handling” but offers no rationale for the angle progression, and none of the launch coverage, including Pinkbike’s, got an explanation out of them. A builder making an unconventional choice should be willing to defend it in public.
One thing they have not thought as carefully about: the seat tube angle goes the wrong way. It slackens from 75.5° on XS to 74.5° on XL, which is backwards. A tall rider runs far more seatpost extension, and every millimetre of extension on a slack seat tube pushes the saddle further behind the bottom bracket. The XL already has the least favourable weight distribution in the range and the slackest seat tube compounds it on steep climbs. Size-specific practice elsewhere steepens the seat tube on large frames for exactly this reason.
What the sliders actually change
Pinkbike reports a 420 to 445mm chainstay range for the optional sliding titanium dropout. That figure does not appear on Litespeed’s product page, which lists 445mm flat and documents no adjustment range at all, so treat it as single-sourced until Litespeed publishes it. It is the only adjustment number I could find anywhere.
The useful property of a slider is that it changes almost nothing else. The front triangle is untouched, so head angle, reach, stack and trail are identical at either end of the range. Bottom bracket height does not move, because BB drop is measured from the axle line and the axle stays at the same height. What changes is wheelbase, which drops from 1256mm to 1231mm on an L at full forward, and weight distribution, which shifts rearward: the front centre share rises from 65.2% to 66.6%. That makes the bike easier to loft and pivot and noticeably worse at holding a line on a steep climb, since the front wheel is carrying even less. If you have the sliders, running them long is the more coherent choice on a bike already designed with long stays.
For singlespeed, the slider position is not yours to choose. Chain length quantises in half-inch increments, so your cog and chainring combination dictates where the axle sits, and you accept whatever wheelbase falls out of it. A half-link buys you finer resolution. Worth noting that Litespeed does not state whether the full 2.6″ tyre clearance survives at the 420mm end of the range, and on a 445mm nominal frame pulled 25mm forward, that is a fair question to ask before ordering.
Titanium, honestly
Titanium determines nothing in the table above. Reach, head angle, trail and chainstay length are identical whether the tubes are titanium, steel or aluminium, and they are what dictate how the bike steers, where your weight sits and how it behaves when things get fast. Litespeed’s Superform X tubeset, described as cold-worked into 3D shapes with size-specific wall thicknesses, is real engineering, but it is engineering aimed at fatigue life and stiffness distribution, not at geometry.
The compliance claim deserves scepticism proportional to how often it is made. Vertical deflection at the saddle on a well-built titanium hardtail rear triangle is a few millimetres. The 2.6″ tyre this frame is designed around, run at trail pressure, delivers an order of magnitude more than that. If you want a hardtail to ride smoother, tyre volume and pressure are the lever, not tube material. What titanium genuinely gives you is excellent fatigue resistance, no paint to chip, no corrosion, and the ability to run unfinished for a couple of decades. Those are good reasons. “Titanium feel” is not one.
The 150mm fork problem
Every number in that chart is measured with the fork fully extended at a 555mm axle-to-crown, and you never ride it there. The fork compresses along the steering axis, so vertical axle drop is travel multiplied by the sine of the head angle, and the frame rotates forward about the rear contact patch.
On an L at 20% sag, that is 30mm of travel, about 27mm of vertical drop, and a rotation of roughly 1.2°. The head angle you are actually riding is closer to 63.3° than 64.5°, reach drops by something like 15mm to around 460mm, and stack rises. Full compression, 150mm, is about 135mm of vertical drop and roughly 6° of rotation, putting the head angle near 58° with the bottom bracket dropped correspondingly. These are my calculations, not published figures, and they ignore second-order effects, but the magnitudes are right. The practical point is that the size spread survives the compression intact: the XL is still half a degree steeper than the L at sag, and the XS is still half a degree slacker. The relationship Litespeed designed is preserved through travel even though the absolute numbers are not.
A 150mm fork on a hardtail also makes fork setup a geometry decision rather than a comfort one. Run it soft and you are permanently riding a slacker, lower, shorter-reach bike than the chart describes. With no rear suspension to sag in sympathy, the front-to-rear attitude change is entirely one-sided.
Sizing
The brackets overlap deliberately and the decision points are at 180cm and 190cm. Under 190cm, the L at 475mm reach and 64.5° is the default aggressive-trail fit. Between 189 and 192cm you have a genuine choice, and it is a choice between two different bikes rather than two sizes of the same one: the L is slacker with more trail and a shorter front centre, the XL is steeper, longer and quicker-steering.
At 6’4″ (193cm) I am in XL territory with no ambiguity, and the counterintuitive part is that the biggest frame in the range has the steepest head angle. Do not read 65° as a retreat from the bike’s intent. With an 833mm front centre and a 1271mm wheelbase, the XL has more directional stability than the L does at 64.5°, and the extra half degree is what stops it from steering like a barge. The number to watch on the XL is not the head angle but the 74.5° seat tube combined with a 520mm seat tube length. Tall riders should expect to run the saddle forward on its rails and should think hard before choosing a layback post. If you order one with sliders, leave them at 445mm.
