Reading the Crank extractor item description, I would get; 2. Nimbus ISIS or 4. Allen Key ISIS, which both work on square-taper hubs and isis hubs, but you might need more than a crank extractor to change a hub from cotter-less to isis.
The quax isis hub is the only isis hub available with 48 spoke holes, do you have a 48 hole rim?
 the quax is probably the cheapest isis hub but not necessarily the lightest.
Unless you are very very lucky, the spokes will probably not fit, and it’s generally recommended to change the spokes if rebuilding a wheel.
Stringing a 36 or 48 hole hub to a 28 hole rim will end up with a very odd, and not very strong lacing pattern. You will be much better off getting a new rim to match the hub at the same time. It’ll save you a load of agro in both the short term and long term.
Well, you’ve got a new frame, seat post, and seat. You want to buy a new hub and cranks. All that leaves is spokes and rim. Why don’t you put the old frame, seat post, and seat back where they started, and just build up the other one as another unicycle? Leave the eBay uni as a beater, and build up a MUni or trials or something.
Ill have to give him a call to see whats the easiest way to do it.
Well I have had my uni for about three years, but a month after I got it I had 2nd degree burns to one of my arms in a gas explosion.
Then I started at the end of last summer. But I only had enough time to be able to get to the end of the street before it the weather turned into winter.
Now that the weather is better I have started again.
I have only seen one other unicyclist in York but then again I haven’t been to any of the juggling clubs here.
@tholub that was what I was thinking but I just wondered if it was possible to just change the cranks and hubs. But no such luck.
i thought mine sounded like more of a question where as yours sounds like a thought. But then again I never was very good at English. Dyslexia and a teacher that doesn’t like me, the lessons never went well.
It’s like saying you should be afraid to boldly split your infinitives, something that people got mislead about because they’ve met someone with a Latin obsession or a 100 year old school textbook that told them about a bunch of rules.
