Making Wheels

Hello all,

I'm trying to build some wheels. It's my first time but i've got to start somewhere.

I'm getting a set of Miche hubs and Mavic CXP33 rims. I'm getting them from ribble as they are the cheapest place that I have found.

I have been trying to use spocalc but their only measurement for the hubs is the rear (so I presume that they are the same front and back). I'm planing on a 3 cross pattern and using the ACI Alpina S/S DB Spokes also from Ribble. Spocalc says that I should be using 291.2 and 289.3 spokes. Is it alright to use 290 spokes all round? There is a lot of stuff on the net and there is a lot of different advice coming from all over the place.

Can someone help?

Cheers,
Elliot

suppose you can cut corners and use 290mm ;)

it's possible to use 290 all round.but you will have to take in consideration for the rear wheel dish.

there would be issues with nipples and threads.if you churning out the watts you could brake the spokes or retruing your wheels every 5 mins.

WTF?!?

most miche are double and if dished can style use same spoke length, just tighten one side and loosen the other. the rest is....err.....crap!

Errr. No. ALL Miche track hubs that I have ever seen are single so there is a slight dish. You can definitely get away with 290 on both sides.

Round up or round down?
Everyone seems to have a different opinion (and explanation)…

Also, if i recall correctly, spocalc tends to err on the side of too long so you could even use 289 all around.

Round down to avoid poky spokes

That's what I thought.
But Sheldon says round up…

Anyone know the hub width and diameter for a Miche front track hub?
Google is mocking me. And I'm trying not to scream at my laptop in frustration.

gee i could have sworn i rode into hell today on miche hubs.and being single sides there's a definately a dish there.

Don't all rush to my aid then!
I dug my calipers out and measured them up myself anyway.
But thanks all the same…

this thread reminds me that i should lace up my wheels

+1 to tramps

i do like having spoke lengths rounded off to the shorter one ... and end up building wheels with more spoke tension.

and use one of these so the nipples don't get naughty when you tighten them up:

best thing ever. i'm sure you can strip the spoke and nipple threads using this before the nipple gets rounded off or squashed.

i've seen pictures of double fixed miche hubs online. never managed to get hold of them. dogs you got some? seems like it? :P

Could someone recommend people on here who could maybe help me build my front wheel? I have all the parts and of course the money for the service! Cheers.

arup, trampsparadise, dogsballs, and many others, even me :P
i haven't killed myself or my mate yet so i bet i'm good enough but i'm too busy these days so forget it am i fucking drunk?

here's an idea:
how's about we begin organizing a database of the odder hub/rim specs that we use, since we all pick from the same dozen hub brands and two dozen rim types?

I'll see what I've got tomorrow morn…

good idea.

Well this is the info I used for my Primato's (36h, single sided, LF)
Front:
Centre to flange left 45mm
Centre to flange right 45mm
Flange Diameter = 59mm
Spoke hole diameter = 2.5mm

Rear
Centre to flange left 45mm
Centre to flange right 30mm
Flange Diameter = 59mm
Spoke hole diameter = 2.5mm

It happens.
But don't be getting used to it now.

Here's another question. When measuring by hand, is flange diameter calculated from the outside of the spoke hole or the centre? Again, the intermaweb suggests both. I'm confused. And if it is the outside (and spocalc suggests centre-centre) is that why spocalc errs towards the overly-long?

I'm getting, for a Miche 36h, HF:
S=2.5, d=60, WL=33.5, WR=33.5

Does this sound right? Anybody?

I think you're about right there, cos if anything my spokes were a little on the long side - not enough to shit my pants about, but they could've been shorter without a problem.
However, to put it in a bit of context, getting the flange diameter out by 1mm means that your spoke length is out by a whole 0.2mm (which is less than the amount I rounded the lengths off by). You're not going to go far wrong.

oh and I reckon you're right about those hub widths too;

Front:
Centre to flange left 33.5mm
Centre to flange right 33.5mm
Flange Diameter = 60mm
Spoke hole diameter = 2.5mm

Rear
Centre to flange left 45mm
Centre to flange right 30mm
Flange Diameter = 60mm
Spoke hole diameter = 2.5mm
