Campag/Shimano Dish

Do Campag and Shimano wheels have a different ammount of dish? (10 speed) For instance, if you had some Shimano wheels and changed the freehub to Campag, would you have to redish the wheels?

Unless I have got the whole concept of dishing completely wrong, then the dish of the wheel is the relation between the position of the rim in relation to the hub axle, with the aim to get the rim centred between each end of the axle. T

Therefore, as the hub will still be 130mm wide, the rim should stay in the same place in relation to the hub. I have built many Zipp wheels and dished them so that they are centred on the hub, and the Zipp hubs have Shimano/Campag interchangeable freehubs that do not require re-dishing after changing.

So, in response to your question it shouldn't require re-dishing after you change the freehub.

yes they do. it depends on which hubs you have. some are made to be interchangeable and as such the shimano version compromises its dish down to the level of campagnolo. shimano specific hubs have more dish and build a stronger wheel.

Why's that? Surely a rear wheel with more dish to it means tighter spokes on the drive side and longer, less tight spokes on the left.

Strongest wheel surely has spokes of exactly the same length, like a front wheel.

Depends on how the wheel has been built, but the rim is aligned to the middle of the axle, not the end of the freehub - if you're fitting Campagnolo onto a wheel built for Shimano, it may need adjusting as the freehub body is 3mm longer i.e. you need to respace the axle and therefore re-dish the rim.
