Velo Orange PioletGeometry & Bikepacking Bag Fit2026
Discontinued. Velo Orange no longer lists the Piolet. It's here because these frames stay in circulation second-hand and the geometry is still what you need to pick bags — but you won't find one new.
What it can carry
Mount provision and clearance, as Velo Orange publishes it.
Velo Orange's wording: “Tire: 29" x 2.4" or 27.5 x 2.6" (M, L, XL), 26" x 2.4 (S)”
Geometry
All figures in millimeters except angles. Effective top tube and seat tube are the two that decide frame bag fit.
| Size | Eff. top tube | Seat tube | Standover | Head tube | Stack | Reach | Chainstay | Wheelbase | BB drop | Head angle | Seat angle |
|---|---|---|---|---|---|---|---|---|---|---|---|
| S | 548 | 468 | 756 | 150 | 548 | 381 | 430 | 1044 | 40 | 71° | 73° |
| M | 578 | 483 | 782 | 135 | 591 | 408 | 460 | 1107 | 70 | 71.5° | 74° |
| L | 609 | 518 | 814 | 165 | 619 | 419 | 460 | 1127 | 70 | 71.5° | 73° |
| XL | 629 | 553 | 843 | 190 | 643 | 432 | 460 | 1148 | 70 | 71.5° | 73° |
Bottom bracket height
Roughly 305–335mm off the ground. Velo Orangedoesn't publish this directly — we derive it from their BB drop and a typical 75cm tire diameter, so treat it as indicative rather than exact. It changes with the tire you fit. Lower means more stable and more pedal strikes; higher means the opposite.
Source — Velo Orange's own geometry chart: https://velo-orange.com/products/vo-piolet-frameset — checked 2026-08-18. A dash means the figure isn't published; we leave it blank rather than estimate.
Note: Manufacturer page says "Last chance to get a Piolet!" Wheel size is size-specific: "Wheel Size: 29" & 27.5+ (M, L, XL), 26" (S)". Product copy also says "Medium, Large, and XL use 29 x 2.4" or 27.5 x 2.8" tires," while the spec bullet lists 27.5 x 2.6. Geometry chart image publishes lengths in millimetres and angles in degrees.
Which frame bags fit
Every frame bag we track, checked against this frame's published geometry. Pick your size.
Checking 19 frame bags against a 609mm effective top tube and 518mm seat tube. 19 fit.
Frame bag fit is calculated from Velo Orange's published geometry, so it's as reliable as their chart. Seat packs and handlebar rolls depend on your exposed seatpost and bar width, which no geometry table lists — the bag finder covers those once you add your own measurements.
