View Full Version : Aerospoke - Questions

I'm really into the aesthetic of what aerospoke has to offer, and I have wanted for along time to build up my own wheel set. I have access to a CNC machine and I was wondering if anyone could advise how I could get measurements. Would I have to measure one of their wheels for an autocad drawing or could I just experiment with my own measurements? Do they follow any sort of industry standard measurements?

Thanks in advance.

first of all they are a carbon fiber mold around a velocity aerohead rim, not all alloy like you seem to think.

Now why did you need to go point that out?
I was really curious what his finished pair of solid aluminum Aerospokes would weigh.:D

Thank you for pointing that out. I was however asking about how to go about getting measurements which I could turn into a computerized drawing for the machine. Any suggestions?

I'd probably find a wheel to dimension. What are you planning to cut this out of?

From the velocity website:
700c
Bead seat diameter 622
Weight: 425g
ERD = 602
The Areohead OC is 20mm wide and 20 some deep. The site did not have specs for the Areohead.

You know the hoop size. Now you need the hub and axle size. Measure from the hub flange to rim and you have your propellers for your wheel.

BTW you realize that you are going to have to machine in a hub that is not laced like a traditional hub? Not to mention the try to find the aerodynamic properties/profiles that will not turn your wheel into a propeller?

You could machine in a front hub because the loads would be less, but with the rear. Unless you are really adept I wouldn't. Its an engineering nightmare of forces and loads.

Why not just buy a set, as it's their design, they won't help you, as you will be costing them a sale.

I would like to see a shiny set of Ti Aerospokes. That would be sweet.

Bamboo, it's the new carbon fiber

If the OP is asking these questions, he's probably not qualified to build a wheel that won't explode.

"Standard" Aerospokes are carbon fiber... and at that they're heavier than comparable spoke wheels. Much, much heavier.

Teak tubular. Ala the old track style. That would be sweet. Would not want to commute on that.

Just buy a Mavic IO...should end up being cheaper/lighter/bombproof than all the time and effort you put into designing your own 5 spoke wheel. And you're going to CNC it out of an aluminum block?

Thanks for all the advice, I have decided not to go through with it and make a purchase down the road. It would have been cool but too much work to design.
