Liv Avail Advanced Size Chart: Compare XXS and XS Before Choosing
The Liv Avail Advanced size chart puts a rider measuring 154 cm inside both the XXS and XS reference bands. That overlap is present in Liv’s published table: it is not a reason to invent a rule that everyone between two sizes should choose the smaller frame. Compare the two actual columns before arranging a fitting.
Liv Avail Advanced size chart: the overlapping pair
The US 2026 Avail Advanced 2 page gives XXS as 145–156 cm and XS as 153–162 cm. These are rider-height references, whereas the geometry section describes the bicycle. Keeping those two tables separate prevents a height recommendation from being mistaken for a measurement of the frame.
| Published entry | XXS | XS |
|---|---|---|
| Reference height | 145–156 cm | 153–162 cm |
| Stand-over height | 683 mm | 712 mm |
| Frame stack | 510 mm | 528 mm |
| Frame reach | 363 mm | 373 mm |
The XS therefore has a taller published stand-over and stack, as well as more frame reach. Those differences describe the two frames; they do not predict whether either will let an individual rider reach the controls comfortably. The chart supplies neither an inside-leg recommendation nor a universal clearance margin to subtract from the stand-over figure.

Turn the overlap into a useful appointment
Tell the dealer which two columns you are considering and bring the details of any bicycle whose position already works for you. Liv explicitly describes its chart as a reference and asks riders to consult an authorized Liv or Giant dealer to determine the correct size. Its height bands are a starting point for that conversation.
Ask to discuss the actual complete setup, including the bar and stem supplied with each size. A frame comparison and a contact-point assessment answer related questions, but one cannot finish the other. No personal fitting, ride assessment or saddle-height prescription is reported here.
The listing identifies Liv Avail Advanced 2 Bike — Moonstone / Gray. Its five recorded size choices include both XXS and XS; that catalogue list does not establish which example is currently available or which size is right for you. The Liv range introduction explains the endurance platform, and the Liv topic groups the model references.
FAQ
Does 154 cm automatically mean XS?
No. That height falls within both published reference bands and needs an individual assessment.
Is 712 mm a recommended rider inseam?
No. It is the XS frame’s listed stand-over height, a different kind of measurement.
Can the same height chart cover every Avail year?
This comparison uses the US 2026 Advanced 2 page. Another version needs its own record.
