SWI Geometry & Size Guide — Aequus and Aequus Leve

Start with fit. Build a bike with soul. This is the official SWI Aequus and Aequus Leve geometry chart, brought together by The Wheelhouse, your Canadian premium SWI dealer in Calgary. Both frames share the same mould, geometry and seven factory sizes: 48, 50, 52, 54, 56, 58 and 60.

Choose your frame by its measurements, not by the size printed on your current bike. Standard and custom carbon layups use the same geometry; custom layup tunes the structure for the rider, not the shape or dimensions of the frame.

SWI Aequus & Aequus Leve geometry chart

All lengths are in millimetres. Angles are in degrees (°). Size numbers are SWI's factory size designations. They are not the measured seat-tube lengths; those are shown separately in row B. On a phone, swipe the table horizontally to see every size.

How to choose your SWI frame size

Frame stack (row K) is the vertical distance from the bottom bracket centre to the top of the head tube. Frame reach (row L) is the horizontal distance between those points. They are the useful starting point for comparing an SWI frame with a bike that already fits you.

Stack and reach are frame measurements, not the final handlebar position. Cockpit length, headset spacers, bar shape, saddle position and seatpost offset also affect the fit. Rider height alone cannot reliably choose between sizes, so we do not publish generic height bands as a substitute for a fit assessment.

Not sure which size to order? Bring your current bike dimensions or fit report to The Wheelhouse. Our Calgary team can review the frame, cockpit and saddle position before the build is specified. Explore IDmatch bike fitting or contact our SWI build team.

Cockpit and seatpost options

SWI lists integrated handlebar widths of 380, 400 and 420 mm and stem lengths of 90, 100, 110, 120 and 130 mm. Its 27.2 mm seatpost is available with 0 or 20 mm offset. The Wheelhouse will confirm the available cockpit combination and suitable seatpost before your order; not every listed width and length should be assumed to be a stocked combination.

SWI geometry questions

Do Aequus and Aequus Leve have different geometry?

No. SWI states that both use the same frame mould, geometry and seven sizes. The main difference is the outer carbon lamination and frame weight, not fit.

Does custom carbon layup change the frame size?

No. The custom layup tunes carbon across twelve zones for rider weight, power and ride feel. The factory geometry shown in this chart stays the same.

Can I copy my size from another brand?

Not reliably. Compare stack, reach and your fitted contact points rather than assuming another brand's size number means the same thing.

Where can I get help with SWI sizing in Canada?

The Wheelhouse is SWI's listed dealer in Calgary, Alberta. Contact our team for sizing, IDmatch fitting and a road groupset and wheel build consultation.
