Headset parts

[zobman]

Looking for a good site to purchase headset parts, like crown races and bearing cups. Looking for low cost replacement parts for reusing hacked bikes.

I'm not sure they have cups, but this place has some of the headset bearings and parts.

It looks like they also carry the cups and crowns at bikepartsusa.

Hacked three different bikes all have different sizes of head tubes? Not sure, how to measure to order parts for any of them. Do you go by the steering tube measurement? Looking for parts on differnet sites and not sure what head tubes sizes should be. The steering tubes are all 1", but the races and bearing cups are all different. Can anyone help with what to measure to order parts. THey are all cheap bikes. Some mountain, some road.

I don't know enough about them to help zobman, but you might try either calling or emailing these guys at

I tend to call everyone now (faster response), but I have Skype's unlimited calling so, it costs me only $2.95 a month to do so.

Here are two articles on measuring headset parts

1" headtubes come in 21.1 mm and 22.1 mm. Measure the inside diameter of the steering tube. There are also 1 1/8" headsets. Here are some links:
