Wheel spindle
Front wheel spindle for Triumph front hubs, the shaft the front wheel and its bearings ride on.
This is a front wheel spindle, the shaft that the front wheel actually spins on. It passes through the hub and the fork end caps, and the wheel bearings ride on it. The catalog carries this one as 37-3582, which replaced the earlier factory number 37-2057 - same part, later number, so if your parts book or an old invoice shows the 2057 number, this is the current equivalent.

It shows up across several front wheel figures in our records, including the T100R and T100C listings, plus separate entries for an earlier and a later style of front wheel, so Triumph made more than one version over the years depending on hub and fork setup. Because of that, don't assume one spindle fits every front end - check yours against the fork end caps and hub before ordering.
If you're pulling the front wheel for a bearing job or tire change, this is the shaft you'll be sliding out. Worth a look at condition while it's out - straightness matters here since it locates the wheel in the fork legs.
