Where can I buy a hub adapter?

[Mind_Reader7]

I need a place that will ship to Australia. RSE carries them, but has been out of stock since forever. I noticed my sprocket was kinda wonky, and I took it off to look. It was warped for some reason. I just spent 2 hours trying to fix it, never want to do it again.

Pirate Cycles, ad on top right carries a real nice sprocket adapter. I have no idea if they ship to Australia or not, they probably do, but I'm sure they'll have an answer for ya if ya ask.

What size hub are you looking for. Ive got a spare at home that is 1.50 inches

How exactly do I measure the hub?

I got a cable tie, wrapper it round the hub, it was somewhere between 3.8-4inches (not 100% sure) and divide by 3.14 = about 1.2-1.3 inches. Is this how I measure it?

 

[skjjoe]

that's close but you need a set of calipers to get it right and measure in three different places across the hub . it sounds like mine is too big

What three different places?
I figured it would just mount in the middle of the hub.

all hubs are not completely concentric .think of an hourglass but not that extreme .if you check it in three places (right side center and left side ) then average it then you will know what size you need. sounds like your close to 1.25.

Ah ok. But now I'm wondering why would need to measure the outer of the hub? Shouldn't the adapter just be mounting on the flat part of the hub, not the inclined bits?

 

[skjjoe]

yes but some hubs are not flat all the way across. take the jaguar hub for instance looks like this )( that's a little exaggerated but its about 5 to 10 thousands smaller on the center of the hub. just make sure you measure it on the flat part in a few places to get a good average. and make sure you dont have one of those rarer hubs . read this post http://motorbicycling.com/f3/jims-sprocket-adaptors-great-value-7636-5.html
