hey, Hi, help, lol, just getting back in the game, Im older(40s) put together an ok budget beginner bike, craigslist, ebay , trade etc, finally got some wheels on trade, Maivc rims with Ringle Hubs, older ones I guess, I have never had sealed hubs like this, just came back from a ride earlier, was fine heading out ,on way back it feels like when I stop pedaling t bike slows down faster than before with the factory rims. I can pick bike up and they spin fine off the ground, would they need regreased or skewer to tight? Never had sealed hubs , so not sure o maintenance, or is it my imagination?
