Wheel trued but not straight

Hi all!

I just got new Mavics A719. The problem is that although they are trued perfectly and they sit all the way at the bottom of fork dropouts the rim is not centered between the forks at the point near the bottom bracket. Between the forks around the brake area everything is fine, it's perfectly in the center but if you follow the rim down to the horizontal forks it's there that the rim leans to the right. What to do? ;( Is that because the spokes on one side are tightened too much causing the rim to be off the center of the hub? As I said the wheels are trued and there's no problem.

Thanks in advance guys and gals!

Looks like you need to redish the wheel, if you are not familiar with building and setting up wheels bring it to your LBS to have a look at. Do a search on how to dish a bicycle wheel if you want to learn more. I am sure someothers will be along to chime in on this as well,good luck.

It could just be a bit crooked in the dropouts. Mount the wheel in reverse. If it's off in the same direction, it's how the wheel is mounted. If it's off in the opposite direction, it's probably wheel dish.

I mounted the wheel the other way round and it's bent the opposite direction. That would indicate bad truing then. Ehhh, another 15 quid to spend. At leas I know that it's not deformed frame or the rim.

True and dish aren't the same thing. A wheel can be perfectly true but not dished properly. Dish is required for a rear wheel to center the rim between the locknuts and that seems to be your problem. If you paid someone to true the wheel, proper dishing should have been done then and they should complete the job at no extra cost.

Oh! Thanks for an explanation At least now I'll be able to explain the the guy at the shop what the problem is. The problem is I live in London and the wheels came from the country where I come from originally (Poland). For me that means spending money on redishing the wheel nevertheless.

Thanks!!!
