M: stack 530 → 562 mm
L: stack 547 → 581 mm
XL: stack 567 → 600 mm
XXL: stack 585 → 615 mm

On the Lapierre website, stack for sizes M to XXL is 30–35 mm lower than the head tube length and angle and the top tube length allow. It’s a typo on the manufacturer’s site. I remember it from 2022, when I sold Lapierre and rode a Sensium myself. I worked out the stack from the head tube, starting from size S, and the top tube confirms it.

52: stack 535 mm, reach 382 mm (calculated)
54: stack 551 mm, reach 383 mm (calculated)
56: stack 565 mm, reach 389 mm (calculated)
58: stack 579 mm, reach 394 mm (calculated)

The manufacturer doesn’t publish stack and reach. I worked them out from the angles, the effective top tube and the head tube, assuming a typical road fork (372 mm axle to crown, 47 mm offset) and 70 mm BB drop. The wheelbase agrees to within about 5 mm. Accurate to about ±10 mm for stack and ±5 mm for reach.

49: stack 535 mm, reach 372 mm (calculated)
52: stack 548 mm, reach 378 mm (calculated)
54: stack 565 mm, reach 378 mm (calculated)
56: stack 583 mm, reach 387 mm (calculated)
58: stack 609 mm, reach 394 mm (calculated)
build size 59 → 58

The manufacturer doesn’t publish stack and reach. I worked them out from the angles, the effective top tube and the head tube, assuming a typical gravel fork (395 mm axle to crown, 50 mm offset) and 72 mm BB drop. The wheelbase agrees to within about 2 mm (7 mm for size 54). Accurate to about ±10 mm for stack and ±5 mm for reach. The builds are sold in size 59 (XL), while the geometry table’s largest size is 58. I’ve treated them as the same frame.

build size M/52 → M

The manufacturer sells sizes 47/50/52/54/57 cm, but the geometry table says XS–XL. Size 52 is M.

L/56: reach 385 → 393 mm

Scott’s website gives a reach of 385 mm for size L, shorter than size M (391). The top tube and seat angle put it at 393 mm, and the same sum is within 1–4 mm for the other sizes. Most likely a typo.

S: stack 542 mm, reach 370 mm (calculated)
M: stack 562 mm, reach 375 mm (calculated)
L: stack 583 mm, reach 379 mm (calculated)
XL: stack 603 mm, reach 385 mm (calculated)

The manufacturer doesn’t publish stack and reach. I worked them out from the fork length and offset, the angles, the head tube, the top tube and the BB drop. The wheelbase agrees to within about 2 mm. Accurate to about ±5 mm (I don’t know the height of the lower headset cup).

S: stack 538 mm, reach 376 mm (calculated)
M: stack 559 mm, reach 375 mm (calculated)
L: stack 591 mm, reach 379 mm (calculated)
XL: stack 610 mm, reach 383 mm (calculated)

The manufacturer doesn’t publish stack and reach. I worked them out from the fork length and offset, the angles, the head tube, the top tube and the BB drop. The wheelbase agrees to within about 2 mm. Accurate to about ±5 mm.

S: stack 532 mm, reach 382 mm (calculated)
M: stack 547 mm, reach 383 mm (calculated)
L: stack 563 mm, reach 384 mm (calculated)
XL: stack 582 mm, reach 393 mm (calculated)

The manufacturer doesn’t publish stack and reach. I worked them out from the fork length and offset, the angles, the head tube, the top tube and the BB drop. The wheelbase, though, comes out 10–19 mm off the manufacturer’s table, so one of the published figures is wrong. That makes it accurate to only about ±15 mm.

S: stack 537 mm (calculated)
M: stack 564 mm (calculated)
L: stack 577 mm (calculated)
XL: stack 598 mm (calculated)

Pells publishes reach but not stack. I worked the stack out from the reach, the effective top tube and the seat angle (73.5°). The steps between sizes match the head tube lengths to within 1–2 mm. Accurate to about ±5 mm.

M: stack 606 → 577 mm

Lapierre gives the same stack for M as for L (606 mm). From head tube length and angle, M comes out at about 577 mm, so it’s a typo on the manufacturer’s website.

XL: stack 654 → 618 mm

Pells’ geometry table gives 654 mm for XL. A head tube 30 mm longer than on L gives about 618 mm.

60: stack 664 → 634 mm

Raymon gives a stack of 664 mm for size 60. A head tube 25 mm longer than on 58 gives about 634 mm.

M: stack 612 → 587 mm

Polygon gives a stack of 612 mm for M. From the head tube it works out at about 587 mm, and size L (621 mm) confirms it.

XXS: reach 326.6 → 357.5 mm

Guerciotti gives a reach of 326.6 mm for XXS. From the top tube, stack and seat angle it works out at 357.5 mm, and the same sum is spot on for sizes S to XL.

XL: head angle 75.5 → 72.5°

Argon 18 gives a 75.5° head angle for XL. From the wheelbase and the other dimensions it works out at about 72.5°.

56: stack 579.5 → 597 mm

Basso gives a stack of 579.5 mm for size 56. From the top tube, reach and seat angle it works out at 597 mm, and the same sum is spot on for the other sizes.

XS: head angle 75.4 → value removed, seat angle 75.4°
S: seat angle 74.8° (calculated)
M: seat angle 74.2° (calculated)
L: seat angle 73.6° (calculated)
XL: seat angle 73° (calculated)

SAVA gives a 75.4° head angle for XS, which matches the seat angle. I don’t know the real figure, so I’ve left it blank. SAVA doesn’t publish the seat angle. I worked it out from top tube, stack and reach.

XXS: head angle 75 → 71°, seat angle 71 → 75°
XS: head angle 74.5 → 71.5°, seat angle 71.5 → 74.5°
S: head angle 74 → 72.5°, seat angle 72.5 → 74°
M: head angle 74 → 72.5°, seat angle 72.5 → 74°
L: head angle 73.5 → 73°, seat angle 73 → 73.5°

On the Pardus website, the “Seat tube angle” and “Head tube angle” rows are swapped for the Robin Sport (a 75° head angle on an XXS makes no sense). I’ve swapped the values back, which matches the other Pardus models.

S: bar width 420 → 380 mm
L: bar width 480 → 420 mm

The manufacturer gives two widths for these bars: at the hoods and at the drops (the bars are flared). I’d entered the width at the drops by mistake. It’s now the width at the hoods, as for every other bike on sedimi.bike. The bar position isn’t affected.
