Royce rear track hub = dished wheel?

Hi,

I have a brand new pair of royce track hubs which i will be getting built up today,

I was just looking at the rear hub sat in the frame, and to me the distance from the drive side flange to the frame seems slightly smaller then the non drive side, which raised the question... so will the wheel be slightly dished?
I had assumed that it would'nt be.

Anyone else have some royce hubs and know if the rear wheel is slightly dished?

I will call royce later, not sure they are open saturdays though, i just called and no answer, however it is still early.

thanks in advance

deffo broken and only good for the bin, in fact I'd be doing you a favour by giving you a tenner for then :^]

noice hubs…

:) deal, they are yours for a tenner. you can always use them as paper weights.

But seriously does anyone know?

If its single sided, and there isn't a HUGE cone thing designed to balance the dishing of the hub then yes, it has to be dished, like single sided Phils.

The easiest thing to do is measure the distance from the flange to the end of the outer cone. If its the same no dishing required. If its not dishing required.

Thanks, yest it is single sided, royce only have single sided, I measured the distances either side and there is about 4mm difference, so a little dishing will be required.

probably not much, spokecalc might even throw up such close numbers that you can use the same length spokes both sides, you know, for the win, like.

I did have the numbers at some point - something like 29mm/31mm.

It makes fuck all difference to the build. Same length spokes both side, and make sure things are sweet with your dishing tool.

i thought royce hubs were made so that they don't have to be dished.

Yeah, I wouldn't call it a dish. It's just the centre to flange distances are slightly different, for some esoteric reason Cliff mentioned; that I've forgotten.

I used the same length spokes either side, and yes it is only very slightly
"dished". The distances are very slightly different, i measured the differences either side of the flanges today, about 2 and a bit milimeters shorter on the drive side.
I will speak to cliff on monday and find out why there is a slight "dish".

The single sided hubs are built asymmetric to give a bit more bracing angle on the non-drive side spokes, which makes the wheel slightly stiffer laterally. Rational design of cycle hubs pretty much dictates that the bearing centreline is fairly close to the flange centreline to keep the load path through the hub shell as direct as possible, and maximising the bearing spacing adds a bit to radial stiffness of the complete wheel by moving the load application on the axle closer to its support point. Both are tiny effects, as demonstrated by the success of symmetric double sided hubs, but Phil, Royce, Campag are all asymmetric on their single sided hubs, and I assume Shimano, Suntour and Suzue are too although I haven't actually seen them in the flesh to measure. They build up with a little dish, although you could build them practically dishless for 126mm OLN conversions by putting the spacers in the non-drive side only if you could live with the +3mm chain line

Thanks for the info, it definetly makes sense, however i'l let you all know what cliff says on monday.

and cliff will be thinking, " not another hipster, shhhesh".....

Haha, although trust me i'm no hipster! :)

Surely f anyone is using a Royce on a frame that has 126 spacing they have spent a dissproportionate amount of their budget on hubs?

I don't think you'll get such a lucid answer from Cliff.

There are some sweet old 126mm frames out there which, even at nearly 20 years of age, still warrant Royce hubs.
