A2Z hubs dimensions


Racer X

Recommended Posts

Hi Guys,

 

 

 

I am building up some new hoops, ZTR Olympics/ A2Z hubs/ DT Revolutions.

 

 

 

I have the ERD for the rims but need to know the hub dimensions, does anyone have the pitch circle diameter and the flange distances for the A2Z superlight hubs? If not does any one know where I can get them off the web, I can't find the figures any where.

Why don't you just measure it?

 

I build a database of hub and rim dimensions but that one's not on there yet. Measure it and share.

Fair point. In all honesty I don't have the hubs yet, they are somewhere between points A and B where I am point B. I wanted to order the spokes so they arrived with the hubs, less lag time etc.

I'll get the measurements ASAP and post them.

OK. That's exactly the problem I have with half the wheels I build. I can only order the spokes once I have the components at hand and have confirmed measurements.

Those hubs are the old American Classics, I understand. If you have an AC that looks the same, then it probably is the same and you can use the AC measurements.

Otherwise, get them to me and I'll measure and publish the dimensions.

I had a look at the CAD drawing and the dimensions that matter are as follows:

 

Front Hub

 

Spoke hole:  2.4mm

Spoke hole diameter left flange: 56.5mm

Spoke hole diameter right flange: 60mm

Centre of left flange to centre of hub: 22.4mm

Centre of right flange to centre of hub: 29mm

 

Rear hub:

Spoke hole: 2.4mm

Spoke hole diameter left flange: 56.5mm

Spoke hole diameter right flange: 39.5mm

Centre of left flange to centre of hub: 22.5mm

Centre of right flange to centre of hub:  29mm

The No Tubes Olympic/ A2Z Build seems quite popular. Here's the required spoke lengths using the DT calculator.

 

Variables used:

 

> A2Z XCF - 32 disc hubset

> No Tubes Olympic ZTR rims

> DT Swiss Revolution Spokes, 1.8 - 1.5

 

Build done using a 2 cross lacing pattern.

 

I am sure the length are correct, maybe Johan would be able double check them?

By now you should have completed your first 10 000kms on your wheels and you are still fiddling around with spoke calculations! Tsk, tsk tsk...

 

If you have plugged the right figures into the right boxes, your calculation will be fine.

 

However, if you are building with Revolutions, round down another mm at least. Those things stretch like crazy under tension and you then end up with thread sticking out beyond the nipple, making it impossible to use a screwdriver to remove a rounded nipple.

 

I'll also stay away from the aluminium nipples, but I know you won't

Mine are allready built and running, done about 4000 Km, problem free.

 

Just thought I'd be nice, I'm having a good day and post the measurements up for everyone else to see.

 

I got my spokes measured at the LBS, that was a bad day and I was feeling lazy. Then did the buid myself.

 

Aluminium nipples, me!!! Never...They looked so nice in silver and weighed alot less

Yeah as mentioned above, mine have been running for a while now. Good value hubs and pretty light weight as well. Not the fastest engaging units on the market but hell @ the price I'm not going to argue.
