Hub OK to rebuild?(9 posts)

Hub OK to rebuild?pitt83
Jan 3, 2004 9:41 AM
I've ridden this hub only about 1000 miles and maybe 30 hours on a trainer. I hit a stick once and put a flat spot in the rim ending the life of that wheel.

I'm going to try and build my first set of wheels and thought this old hub was a good candidate. So, when I removed the spokes, the hub looked like the attached photo.

Is that elongation normal? I'm building the same 3X pattern and will be pulling in that same wear direction. Should I trash this hub and start a new one? The front will be new as that wheel was sold with the bike, but not this rear. It's 105 so it doesn't break the bank to buy new, but if it's still OK, I'd like to get more mileage from it. The hub spins just fine and the free body is perfect.

Thanks in advance from a newbie wheelsmith.

.....to me the holes look pretty crapped out. I'd rather start new considering how long a wheel usually lasts.

IMHO, it's fine. Your new one will look the same as soon as it is built.

You just need to make sure the spokes follow the same pattern in the hub as the original build. That pattern develops as the wheel is built or shortly after in use. It's not a wear pattern or a sign of damage. The chances of this being a problem are EXTREMELY small. To me, the hub looks (and is) virtually brand new.

It's just fine Dave. Switch the spoking pattern so that the spokes dig into the other side of the hole.

For those who say that you MUST follow the original spoking pattern well, that's just their opinion. I've done it many times the other way and the sky didn't fall. The hub flange didn't self-destruct either.

Recently I got the latest Sapim brochures with their wheelbuilding tips - they suggest, when re-using a hub, to switch the pattern to the opposite side of the hole.

but yet again when I rebuild wheel I always go with same rim or rim of close ERD. That way I don't have to relace it, just tape at cross and switch rims.

I've rebuilt wheels both ways: following the previous build and going opposite. Both seem to work equally as well.

As always YMMV...

I'd guess they're probably OK but I'd sure check before I got even this far.

The flanges look OK to me. Nearly everybody says to use the same spoking pattern. In the past I've done it several different ways. I've just used whatever pattern I felt best, I've used the same pattern just because, and I've reworked the flanges with a Dremmel before changing the spoke pattern. To my knowledge, none has ever failed due to the problem you seem to be concerned about.

The hub spins smooth as new. I will use it and thought it was usual wear. It's the first time I've ripped down a wheel and was surprised that a hub that lightly used could actually not look out of the box new.

Looking at my other bikes, that hub is indeed fine.

Thanks all.
