Liv D-Fuse Handlebar: Separate Clamp Size, Width and Flare
A Liv D-Fuse handlebar enquiry needs more than one number. The US 2026 Avail Advanced 2 specification lists a 31.8 mm figure and size-dependent widths from 380 to 420 mm; its performance description separately mentions an eight-degree flare drop. Each entry describes a different part of the comparison.
Liv D-Fuse handlebar dimensions by frame size
The named component is Liv Contact SL D-Fuse. Its listed widths are 380 mm for XXS and XS, 400 mm for Small and Medium, and 420 mm for Large. The 31.8 mm specification accompanies the bar entry; it must not replace those width figures in a note headed “handlebar size.”
| Frame group | Published bar width | Published stem length |
|---|---|---|
| XXS and XS | 380 mm | 70 mm |
| Small | 400 mm | 80 mm |
| Medium | 400 mm | 90 mm |
| Large | 420 mm | 90 mm |
This pairing shows why a width alone does not describe the complete cockpit. Small and Medium share the same bar-width entry but have different stem lengths. The source does not turn either combination into a recommendation for a particular shoulder width, hand size or riding position.
Keep flare separate from the width label
Liv describes an ergonomic bar shape with an eight-degree flare drop. The captured product table does not specify the measuring position used for its width entries. Do not calculate an exact hood width or drop width by assuming a convention from another handlebar.
When comparing a replacement, request the applicable drawing and complete component identifier. Include the actual frame size, bar and stem rather than discussing “a 400 bar” in isolation. The relevant fit question concerns the positions you use on the assembled bicycle; a catalogue width is one part of that evidence.
The listing identifies Liv Avail Advanced 2 Bike — Moonstone / Gray. Ask which documented cockpit accompanies the chosen size if the offered bicycle differs from the standard record. No bar swap, compatibility approval or installation setting is established here. The Liv brand introduction and model topic help keep the road-platform context attached to that enquiry.
FAQ
Does 31.8 mm mean the handlebar is 31.8 mm wide?
No. The specification gives the separate width entries by frame size.
Is the Large bar width listed at 420 mm?
Yes. That is the published width for Large in this US model record.
Does the page define an exact width at the hoods?
It does not identify that measuring convention, so no converted hood-width figure is supplied here.
