I recently overhauled my theadless headset. When I put it back together after cleaning and relubing, it seemed grindy still, and not as smooth. I loosened the headset cover all the way but this only helped slightly. The headset isn't loose or too tight but i still feel grinding slightly. I'm not sure where to take it from here. could the bearings be installed backwards? I believe I put them back the same way they came out.
Thanks for any help

It's likely one of the components was re-installed incorrectly. I would try reversing the bearings to see if it makes a difference.
