FRONT WHEEL COMPLETE
Complete front wheel assembly for Triumph, listed under catalog number 37-3904 (also W3904).
37-3904 is the complete front wheel assembly, listed in the FRONT WHEEL figure of the parts books. This is the whole hoop as it left the factory - hub, rim, spokes, and bearings assembled as one unit rather than a collection of parts you'd have to build up yourself. The older parts book form of this number shows up as W3904, so if you're cross-referencing an earlier catalog or a tag on a used wheel, that's the same piece.

Our catalog record ties this to appearances across 1971 through 1973, but we don't have more detail on this one beyond the figure it's listed under. Front wheel assemblies vary by hub width, spoke count, and rim size depending on brake type and model, so before you order, check what's actually on the bike or send us photos of what you've got.
If you're rebuilding rather than replacing outright, we can also help source the individual hub, rim, and spoke components separately - but as listed here, 37-3904 is the complete wheel.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
Sorry if we got something wrong here. If you think this information isn't correct, .
