wheel building problem

Ok so I am having some mega problems trying to build the front wheel for my new bike.


I ordered two brand new Mavic CXP 33 700c rims and have a shimano paralax hub that i bought new from ebay.


A friend of mine laced up the wheel a while ago but the spokes were a little too long and something was off. So we re-did it today with slightly shorter spokes and the whole thing is beyond crooked (not just out of tru) and we can't for the life of us figure out what is wrong. I couldn't even get the last few spokes laced up.


Maybe the hub is messed up somehow, but I'm really not sure. Has this happened to anyone/ anyone have any suggestions?


I've been working on this bike for awhile and everything seems to be going wrong. It really sucks. Any help would be greatly appreciated.

Sounds like your spokes might be off by a hole. Meaning the spokes in one flange need to be moved one hole over. I've done this a few times, and everything seems fine until the last handful of spokes.


Might want to take it apart (again) and re-lace, using the instructions on Sheldon Brown's site.

Wait, I see your problem. You have one too many rims.

ha ha...my rear wheel has a sturmey archer 3 speed internal in it and laced up fine, using the same process i used for the front hub. i will look into the one spoke off thing though, maybe that is the problem. is there any way to tell if your hub is messed up?

Hard to say what "messed up" means. Bent? I'm having a hard time imagining "beyond crooked."

I think it's a spoke length issue. If it was messed up once it's probably messed up again. That you couldn't get the last few spokes laced also makes me think that.

i'm going to agree with eric. 9 times out of 10 if someone has that problem, it's that the spoke holes are one off relative to the rim. the spoke holes in a hub are offset from flange to flange (only paired spoke design hubs have the spoke holes directly across from each other).


the hub itself is not messed up.
