Marin Four Corners 1 CUES: identify the listed components individually

Marin Four Corners 1 CUES identifies a current equipment version, but the CUES name is only the beginning of a useful parts record. The manufacturer's current CUES listing separates the controls, derailleurs, crank, cassette and chain into individual rows. Read those rows before assessing whether a used example matches the reference or asking a shop for replacement equipment.

Read the Marin Four Corners 1 CUES identifiers

The listed rear derailleur is Shimano CUES RDU3020, described as nine-speed, while the front derailleur is FDU6030. The dual-control entry is STU3030 in a two-by-nine arrangement. The crank row identifies FCU6030-2 with forty-six and thirty-two teeth. Save those component names as separate entries rather than reducing the entire list to a gear count.

The cassette row gives CUES CSLG300 with an eleven-to-thirty-six range, and the chain entry is Shimano LinkGlide LG500. The bottom bracket is described as Shimano outboard bearing. Those are the manufacturer's recorded entries; a chain model name or a bottom-bracket category should not be silently rewritten into a different part number that the source does not provide.

Include the braking controls in the record

The brake rows identify Spyre-C road mechanical discs with 160-millimetre rotors front and rear. The lever row identifies integrated CUES shifting controls. A familiar CUES hood therefore does not establish that a bicycle has hydraulic brakes, and a seller's phrase all Shimano does not accurately replace the manufacturer's individual brake and drivetrain fields.

Ask for readable markings on the actual equipment when the bicycle is not available for inspection. Record confirmed replacements beside the original-list column. A substituted component deserves a compatibility and condition check, but a difference alone does not diagnose the whole bicycle or establish when a particular part was changed.

Use the list for a defined ownership question

For a used purchase, separate original specification, current installation and current wear. A matching model number cannot prove correct adjustment or a serviceable chain and cassette. If the goal is repair, describe the symptom and give the workshop the actual installed identifiers instead of ordering the first component labelled nine-speed.

Keep the source's model scope explicit. The accompanying exhibition photograph was taken in March 2025 and is a historical Four Corners example, not confirmation of this current CUES configuration. The current listing also reserves specification changes. Obtain the actual supplied equipment list when arranging a new purchase, and preserve any agreed differences with the bicycle's documents for future service.

CUES build-reference FAQ

Does this reference describe a three-by-nine drivetrain?

No. The current CUES listing explicitly describes two-by-nine controls and a forty-six/thirty-two double chainset.

Does an integrated CUES lever prove hydraulic braking?

No. This build's separate brake rows describe mechanical Spyre-C discs; read the braking entry independently.

Can the nine-speed label alone select every replacement component?

No. Identify the complete installed system and have the proposed replacement checked against the applicable component requirements.

A separate identifier for each installed component makes the next parts enquiry useful. To distinguish the brake arrangement, consult brake service interfaces in the Marin collection.
