4 steel mudguard stays for 650 porteur utility bike front rear Vintage

A set of four steel mudguard stays sized for 650 wheels on a porteur utility bicycle. The stays are intended for use at the front and rear of the bike, providing the structural link between the fender and the frame or fork dropouts. This is a used component, and its current state is reflected in the photography that accompanies this listing. One serre tringle is broken, so the set is best suited to replacing a damaged stay on an existing mudguard rather than building a complete new set from scratch.

Condition and Compatibility

The listing includes four individual steel stays. Minor storage-related marks may be present. The main issue to note is a broken serre tringle on one of the pieces. This is not a system with indexed sizing or a brand-specific interface; the stays attach through the standard mudguard stay hardware found on classic porteur and utility frames. The leg length and eyelet positioning are visible in the photos, which serve as the dimensional reference for this item.

What Fits a 650 Porteur Build

On a 650B or 650C platform, these stays work with fenders that require a rigid steel support arm. The front and rear designation means you can address both ends of the bike. For a complete rear mudguard setup, you may also want to look at our 6 Mudguard stay bolts and nuts 4.34 mm D8 for the hardware that threads through the eyelets. If you're sorting out the rest of the rolling stock on a 650 project, the SUPER CHAMPION 650B front wheel offers a matching rim width for this fender type.
