I was servicing my rear wheel on a year 2000 Schwinn Frontier. I found that the cones are worn to kind of a sharp edge and need to be replaced. I have no idea of how to order these. Do I just measure the axle? I will probably replace the ball bearings also. Thanks!

Do you have photos? The cones shouldn't distort, but can get pits which then tear up the ball bearings.

The easiest thing might be to go to your local bike shop to ask if they can match.

Wheels Manufacturing is one of the largest third party manufacturers of replacement cones.

More important is what brand is the hub

If the cones were OEM ones and they wore to the point of a sharp small end being sharp there's a lot of chance the cups are also worn. Do your homework as a replacement wheel can be the lower cost solution when dealing with decades old hub issues. One benefits from new spokes and rim too. Andy

Yeah like others have said, do you have images? Cones tend to pit, but I have never heard of them getting a "sharp edge". If they are actually that worn, it's best to get another wheel.

Andrew R Stewart 

Cones getting a "sharp edge" is just wear that has gone on for way too long. Steel is a material that can be molded and flowed by pressure and cycles of force. Forging is an example of this process done on purpose. With hub cones this deforming is usually from a way too loose a bearing adjustment and as the wheel revolves on the cones the slop increases the banging on the cone's ball track that the balls will do (as the wheel flops from one extreme to the other). This is a different process than what causes pits (and that is from work hardening of the ball track's surface and it's micro cracking, usually from a too tight bearing adjustment.) Andy

I'm having a hard time imagining a wear situation where the pitted cones have turned into rutted cones such that the small end of the cone is now a sharp edge. Such a cone set would really be totally trashed. But maybe I'm misunderstanding the question.

blingshock

That's exactly what I am picturing as well. At least 1 or 2 spokes would definitely break well before the cones get that worn, but then if the spokes started breaking, then the wheel would just not even be rideable at all, so I do not know how a wheel can even get to the point of "sharp" cone edges... unless OP had replaced the spokes before. But if OP has replaced spokes before, then he probably knows how to replace bearings and would not be asking this question in the first place...

These folks (Bike Parts USA) have the cheap axle kits that will probably work with your Schwinn hub. If you brought your Schwinn into a shop, this is what they'd use. If you get the axle too, you don't have to worry about threading. Bike Hub Parts

Sorry but you are wrong. Spokes and cones are two rather different things that have different stresses and different failure modes, their overlap is both get worse with continuing use.

I will say that not knowing why stuff happens does not mean it won't happen. Andy

KerryIrons

What makes you say that? Cones wear due to badly adjusted hubs, lack of lubrication, and poor quality material. Spoke breakage is completely unrelated.

A dry, way over tightened cone may be destroyed on a trip around the block.
