Rough joint on Mavic rims?
I just took delivery of some wheels I ordered with Mavic EN521 rims and am surprised by how rough the the welded joint looks. The milling away of the welding flash has actually left a visible depression in the rim walls, which isn't the most confidence-inspiring thing I've seen. I gather that this is fairly normal for welded rims, but these are supposed to use Mavic's 'SUP' technology which, according to Sheldon, means that the rim is made thicker than normal, welded and then machined down uniformly to leave a smooth join. Are these depressions something to be concerned about?
