Quill stems

sparse

I was hoping to replace the Quill stem on my hybrid with an old road bike quill stem for a lower angle but have hit some problems. The value on the hybrid quill stem reads 25.4 (1") but most of the ones that I've found on ebay tend to be 22.2. What gives!?

I'll take a guess and say that the 25.4mm refers to the handlebar clamp, which was standard for MTB bars. 26.0mm was standard for drop bars so you may need to look around to find a quill stem with a 25.4mm clamp, or you might be able to use a shim.

I'm open to correction but I have never seen a quill stem that was for anything other than a 1" steerer tube so I don't think you need to worry on that count.

Sounds right, I'm pretty sure all quill stems are for 1' steerers. Don't see why you can't find any 25.4 mm bars?? examples here and here,

Quill stems come in two sizes - 7/8" (22.2mm) to fit in a 1" (25.4mm) steerer and 1" (25.4mm) to fit a 1 1/8" (28.6mm) steerer

Huge potential for confusion as both standards include a 1" sizing. Best to measure the diameter of your current stem first. Sighting over a ruler pressed against the stem should be accurate enough to tell the difference but callipers are best

could you clarify those measurements please? what does the 22.2mm refer to, steerer i.d.?

The smaller measurement is for quill outer diameter and the larger is steerer outer diameter

That's what i thought. I'm pretty sure you won't find a quill stem for a 1 1/8" steerer
