trek 400 - need front wheel cones and ball bearings

So I'm rebuilding this bike for a friend.. the front wheel has a little grinding.. so I wanted to buy just the outer ( removable cones ) and a new set on ball bearings.. any Idea where I could obtain these?? John

Typically, you'll have ten 3/16" balls per side.
Shimano alone had dozens of different cones for their various hubs.
Without a brand & model# one wouldn't have a clue which cone you need.
Trying to find replacements for old cones can be near impossible to sometimes very expensive.

If you have actual grinding, I'd inspect the bearing race to make sure it's not pitted before i invested in cones.
Bearings are relatively cheap & generic. Grade 25 is what we usually use, but even lesser grades such as 100 or 200 are suitable. Typically the price difference doesn't justify the cheaper bearing balls.

As a parts those can be difficult to source, a coop or a local shop that sells used bikes could have some old hubs for parting out or replacement set of wheels.

https://wheelsmfg.com/products/hub-p...cones.html?p=2 is another place to start if no coop or old established
LBS is not available. Looks like many are out of stock but the profiles and measurements should be helpful.
FWIW, for casual riding, a bit of grittiness in a hub is of little real consequence. And as noted, sometimes it is
cheaper just to replace a wheel if a secondary or tertiary market for such exists in your area. Older wheels are
sometimes quite nominally priced or free. Just check the rim carefully for damage or humps/wobbles when spun.

Oddly enough a Trek dealer can provide you with all the information and probably even order the parts for you.

I don't know if that is still true for that bike. The Trek 400 was a steel frame road bike sold in the early to mid-1980's so it's been out of production for over 35 years.

I had a 1983 model and the vintage Trek catalog says it came with "Atom alloy" hubs and 27" (ISO 630) wheels. I recall these hubs had conventional cup-and-cone bearings using 10 x 3/16" balls in the front hub and 9 x 1/4" balls in the rear freewheel hub. If the cones are pitted, I'd take them to an older bike shop and just look for a close match. A Trek dealer will probably no longer stock an exact match.

400 was discontinued around 1993, so unlikely.

Yes, and the 400 of 1993 was probably far differently equipped than the 400 of 1983 so the hubs would very likely have been a different make and model.

Nine more posts, and you can upload pics of the cones. Doubt they're that bad.
