Vintage Touring Bike Moustache Handlebar 24.8 - 460 Steel R574

The R574 moustache bar is a steel handlebar intended for a classic touring bicycle. Its clamp diameter is 24.8 mm and its width is 460 mm. The profile follows the moustache shape associated with older road and touring machines, before the widespread adoption of compact drop bars.

Vintage touring bike fitment

The 24.8 mm centre section determines compatibility with the stem. A period-correct stem with the matching clamp bore is required. Handlebars of this type were commonly paired with steel frames and side-pull or cantilever brakes. The 460 mm width gives a narrower hand position than modern gravel or trekking bars, which suits the shoulder width and riding position of many older builds.

Moustache bar profile and use

The moustache shape offers two main hand positions: on the outer curves, with the wrists turned slightly inward, and on the central straight section for a more upright posture. This makes the bar a practical choice for a period-correct touring bike used on longer, steady rides rather than aggressive racing. The steel construction can be bent back into shape more easily than aluminium if a fall or shipping impact causes a minor misalignment.

For a wider alternative, the Eroica Moustache Handlebar 470mm 25mm uses a 25 mm clamp diameter. If you are comparing widths, the Moustache handlebar 24.8 - 440 mm sits slightly narrower than this R574.
