Marin Muirwoods wheel replacement: collect the hub and brake interfaces

Marin Muirwoods wheel replacement needs more detail than the model name and wheel diameter. This reference uses the official Muirwoods 2025.1 27.5 listing, rather than an older Muirwoods catalogue. Its hub and brake entries provide useful starting information, but an actual wheel order still needs the installed interfaces to be identified.

Build a Marin Muirwoods wheel replacement record

The current reference identifies a twenty-seven-and-a-half-inch wheel family. Its hub rows list front spacing of 110 millimetres and rear spacing of 141 millimetres, with thirty-two holes. Record front and rear separately. A pair of wheels does not share one spacing simply because both belong to the same bicycle.

Also state whether the job is a complete wheel replacement or a rebuild using existing components. The listed hole count is relevant to matching a hub and rim for a rebuild, but it does not establish spoke lengths. A workshop needs the actual parts and the intended work, rather than an isolated catalogue number copied into an order.

Keep spacing separate from the complete axle interface

A spacing measurement is not a complete axle description. The cited entries do not give an axle diameter, total length or thread pitch. Do not turn the front or rear spacing into an assumed standard name and order from that assumption. Give the supplier photographs and markings from the actual bicycle, and have the interface confirmed before committing to parts.

Use the exact current build as a comparison, then describe any difference found on the bicycle. This is especially important for a used Muirwoods with an uncertain replacement history. The historical 2021 photograph accompanying this article is a family illustration; it cannot verify the present build's hubs, axle arrangement or factory equipment.

Include the braking and rear-wheel equipment

The 2025.1 table specifies Tektro M275 hydraulic brakes with a 180-millimetre front rotor and a 160-millimetre rear rotor. Include those distinct sizes in the enquiry and have the supplier confirm how the actual rotor attaches to the proposed hub. Rotor diameter alone does not answer the hub's rotor-interface question.

For a rear-wheel order, also identify the installed cassette and its attachment requirements. The current build lists a ten-speed SunRace cassette spanning eleven to fifty-one teeth, but that tooth range is not itself a hub-interface specification. A complete written quotation should resolve the remaining component matches instead of leaving them for discovery after a wheel has arrived.

Muirwoods wheel enquiry FAQ

Does 141 millimetres identify the whole rear axle?

No. It is the listed rear hub spacing; other axle dimensions and the actual interface still need confirmation.

Are the front and rear rotors the same size?

No. The current reference lists 180 millimetres at the front and 160 millimetres at the rear.

Can these entries be applied to every older Muirwoods?

No. Identify the actual generation and fitted equipment before using the 2025.1 listing as an ordering reference.

Resolve the remaining interfaces in writing before ordering a complete wheel or scheduling a rebuild. When the wheel is retained, consider wider-tyre assessment in the Marin collection.
