I'm the one pcad saw who took the stickers off. I had the SL5 front wheel and SL4 rear wheel. I thought they worked great. The bearings were very smooth. I'd still have them but I sold off the bike they were on.
Did I buy another set for the new bike being built? No.
Why not? because for $120 more I got a custom set built with similar 27mm rims (maybe even the same), lighter, stronger spokes, and dt swiss 240s hubs.
