rear wheel spoking(10 posts)

the link leads to some pictures, showing how I want to build my new rear wheel.
involved are a FIR Apollo rim with 24 holes, a Bees Helium hub with 32 holes( )and 24 spokes (2 mm ).
1st picture: the whole wheel
2nd pic: right side (drive side) spoking
3rd pic: left side spoking
4th pic: from above

opinions and tips are welcome.

I tried posting a reply earlier, but apparently it got lost (user error, I suspect). In any case, I'll try to repeat what I said earlier:

I can't really tell what I'm seeing do a degree of certainty from the pics on that sight, so I may be off base. Wht I think I'm seeing is a 8-drop pattern (4 holes left open at the hub on each side, clocked 45 degrees between the hub flanges), with a midified crow's foot lacing to put the crossings nearer the hub. Is this correct?

I certainly don't see anything wrong with this pattern, though you probably don't want to go with gossamer spokes, as you're reducing the number of pulling spokes. The radial spoke doesn't buy you much for torsion, but I don't think it hurtds you either.

under the left corner of the pictures there is a link named "Originalansicht". that means in this case: real size.
if you try this link, you will get the pictures in real size.

Combined two cross and three cross on the non-drive side. Hmm...

Still, I see no problems here. You may need a different spoke length for the three cross spokes, but if you can keep it straight when you lace it up, then it should do fine. As with all builds, be patient.

yes there are different spoke lenghts on drive side and left side.
one reason I did this with CAD was to measure the correct lenghts.

the 2-cross and 3-cross. I'd have to run it through a spoke calculator to know for sure. Of course there's a difference between left and right. They'd be shorter anyway, without the taller flange.

they may work with standard hubs, rims and standard spoking, but i don't trust them in this case.
I got all the necessary geometry from the hub manufacturer, the rim I measured myself.
so I drew it three dimensional with CAD to check possibilities and spoke lenghts.
there are 3 different spoke lenghts on drive side and 2 different spoke lenghts on left side.

liked your idea; i am going to build a 'similar ' whell - that means a 24 hole rim - i think it will be an alex rim
and a 36 spoked stx-rc mtb hub (weight - between tiagra and 105) . I'm still building a road wheel but i think the mtb hub has stronger flanges - (if you have less spokes then the flange is more challenged)
i think with a 36 hole - hub u could build a symmetric wheel - nothing wrong with your project of course - just for the sake of looks maybe: 18 = 6x3 and 12 = 6x2 so for every two used holes u would have one hole free on the hub

hey what means the erd - parameter for a rim? and what kind of spokes are u gonna use?
good luck
