Frog Bikes Track Handlebar Width: Bars, Stems and Fit

Frog Bikes Track handlebar width is one of several measurements to keep during a fitting. Podium lists different drop bars for Track 58, 67 and 70 while listing the same 38mm stem length across the three entries. Those figures describe separate parts of the cockpit. Neither number, by itself, establishes a comfortable position for an individual child.

Frog Bikes Track handlebar width: Compare the named bars

The distributor describes a Frog aluminium alloy drop bar with a 320mm dimension on Track 58, 340mm on Track 67 and 360mm on Track 70. Its tables do not explain whether that published dimension is measured centre to centre or at the outside edges. Keep the catalogue's number and component description together rather than adding an unstated measurement convention.

For each model the stem entry says 38mm and notes that it can be swapped. This is a statement about the listed component, not approval to install any stem carrying that length. Clamp dimensions, the actual steering assembly and suitable installation instructions still have to be checked for a proposed replacement.

Observe the child's position before choosing parts

At a fitting, explain where the child is struggling to reach or maintain a comfortable position. Bring the usual riding equipment and ask the fitter to assess the actual bicycle. Avoid selecting a wider bar simply because it appears on the next model, or assuming a shorter stem will solve every reach problem.

Inspect tape and end protection

All three Podium entries describe cushioned racing tape with caps supplied in the box. Supplied is different from correctly installed. Check that the actual bicycle has intact tape and protected bar ends, particularly when it has passed between families or returned from a session with a damaged contact point.

The Frog owner's manual specifically warns about exposed handlebar ends and asks owners to replace damaged grips, plugs or extensions. Its fit chapter directs owners to seek a stockist's help with handlebar height and stem changes. The general manual does not establish a Track bar position or a torque for an unidentified replacement component.

Keep an adjustment record that can be followed

Ask the fitter to record the installed bar and stem, the reason for a change and any component instructions supplied. Photograph the completed position for identification, while keeping clear that a photograph is not a measurement or tightening specification. A later mechanic needs the part details as well as the appearance.

After an impact or an unexplained movement of the bars, stop using the bicycle and arrange an inspection. Do not keep experimenting with bolt tightness until the movement disappears. The manual's general warning about insufficient or excessive fastener force applies to the need for the correct component-specific procedure, rather than a number guessed from a similar stem.

The Frog Bikes topic separates these equipment questions, and the Frog Bikes brand guide introduces the range. A Frog Bikes Track handlebar width decision should leave the child with an assessed position and clearly identified parts.

FAQ

What handlebar dimension does Podium list for Track 70?

It lists a 360mm Frog aluminium alloy drop bar for that model.

Does the source define its width measurement convention?

No. This guide therefore does not label the figure as centre-to-centre or outside-to-outside.

Does a swappable stem mean every 38mm stem is suitable?

No. Have the actual interfaces, fitting and installation requirements checked before choosing another component.

The Track tables distinguish bar dimensions from a 38mm stem and list tape with caps. Their bar-width measurement convention is unstated.
