16h hubs to 32h rims, will i die?

I have old cosmic carbone hubs that are 16h and I would like to lace them to 42mm deep aluminum hoops, only thing is i cannot get them in 16h and was thinking of lacing them to every-other-hole on a 32h drilling.

I will fill the alternating holes with a touch of expanding glue (weightless)

the rims weight about 640g/each.

1. will this hub/rim combo work?
2. with only 16 spokes front/rear, is the rim sacrificing any durability/strength?

sorry, i am new to wheel building, but my old carbones have eaten their eyelets...

It would be better to do it with a 32 hole hub in a paired spoke pattern, but it can be done on a 16h hub. The trick is compensating spoke length for the slightly off spoke angle.

ah ok thanks man, i didn't want to pollute the road forum more than it already is

i figure this should be a pretty strong wheel, if the carbone rims were any indication when laced with only 16 spokes.

If the rim is drilled right/left then you might have a problem. Otherwise, it should be fine structurally since it's such a deep and heavy rim. Though it's not ideal.

This is also the problem that I see. It seems that deep section wheels will always have alternating offset spoke holes. I guess you could do a left spoke then a right spoke followed by two empty holes, then another left - right pair followed by two more empty holes and continue with this pattern around the wheel. This would result in a paired spoke pattern similar to a Bontrager Race Lite (ugh!). And it would be a nightmare to true.

And there may also be a problem with the type and length of spokes that will work with the Carbone hubs.

Let us know what you figure out.

Al

Can you afford to look at 16H rims? You can get some aero rims through some sites.

hey aki,
yes i would want 16h rims but they are so far and few between..

right now the 42mm set are $89 for the pair, and i guess i should be able to lace them right, although no one can give me a straight answer on if the holes are offset right/left or not...

im guessing i would need a touch longer spoke length for the incorrect offset 8 spokes on a 16 spoke build...?

noting this, would that angle thing (opposite) present any issue in tensioning or strength since it not straight on?
