Moustache Samedi 28 ES Gearing: Identify the CUES and Sunrace Parts Together

Moustache Samedi 28 ES gearing is described by several component names, not one all-encompassing CUES label. The archived build combines Shimano CUES shifting parts with a Sunrace cassette, a narrow-wide chainring and a Shimano chain. Keeping those identities together makes a more useful purchasing or service enquiry than asking for an unspecified nine-speed part.

Moustache Samedi 28 ES gearing: start with the complete list

The rear derailleur is Shimano CUES RD-U3020, listed as nine-speed. The shifter is Shimano CUES SL-U4000-9R, also nine-speed. These entries identify two components; the CUES name does not automatically identify every other part in the transmission.

The cassette line instead names Sunrace CSU98.9AW, nine-speed, 11–36T. Write that supplier and model beside the tooth-range figures. Replacing “Sunrace” with “Shimano” to make the list look consistent would misreport the actual manufacturer record.

Keep front and rear tooth counts separate

The chainring entry says narrow-wide, 40 teeth. The 11–36T figures belong to the cassette at the rear. A note that says only “40 teeth” or “11–36” leaves out which part the number describes.

For comparing a shop description with the archived build, use a short table with component, named model and stated size. This keeps a missing model number visible without inventing one from a broad nine-speed label. The table is an identification aid, not approval for an alternative transmission.

The chain and cranks complete the enquiry

The source specifies a Shimano LG500 chain with 108 links and Stronglight aluminium cranks with a 170 mm entry and ISI wording. Retain those as the listed build details. A catalogue link count is not a chain-sizing instruction for a changed or repaired bicycle.

If the individual bicycle has replacement parts, ask which entries still match and which were changed. Supply the actual model labels to the workshop rather than ordering from the number of speeds alone. No derailleur adjustment, chain-cutting procedure or universal compatibility conclusion follows from this specification comparison.

The Black glossy Samedi 28 ES reference identifies the four-size local model used here. Its colour and size choices should remain separate from the manufacturer component identities. The Moustache range story and Moustache model topic supply broader context without changing the named ES drivetrain.

FAQ: recording the transmission

Is the listed cassette a Shimano CUES cassette?

The cited ES line names Sunrace CSU98.9AW, so keep that exact identity in your notes.

Does 108 links tell me how to cut a replacement chain?

No. It records the catalogue build, not an instruction for sizing a replacement on an individual bicycle.

Does nine-speed alone establish a replacement match?

No. Bring the complete component list and the actual bicycle's details to a qualified service provider.
