These are 9mm axles but biketoolsetc lists 9x1 and "9x1i" threads in a 9mm size - which is correct or are they interchangeable?
I'm looking to use this hub as a rear hub with bolt-on cog. Would this axle work? Are there longer axles available elsewhere? The length would be just sufficient with these (126mm rear spacing) but a bit more would be nicer.
