I have a new fixed gear Kilo TT. I installed a new cog and lockring on the rear wheel. When I tighten the lockring, it causes the axle to sieze up. Ive adjusted the hubs and tried to do so with the lockring already in place, but it doesnt allow the drive side cone to move freely. Its a DuraAce lockring and a Surly cog. The wheel seems to spin fine when I use the stock lockring that came with the bike. Any idea what could be causing the issue, and/or what I should do about it? I have a video demonstrating the issue but I am not allowed to post URLS until I have 10 posts.

Thanks!
