As for ZIPP, that is a quality brand. Their more basic offerings run under the 'Service Course' model and are perfectly fine. Zipp Service Course is comparable in entry level offerings to the 4 brands I mentioned above.

I think what
ArgoMan needs is a shim that would "thicken" his 1" steerer to 1-1/8" so he can use more widely available stems. I also recently had to go that route to attach a 31.8 mm handlebar onto a 1" steerer, because I cannot find a stem for a 1" steerer that would also accept a 31.8 mm handlebar.
