Isolating a ProblemReddpoint81

Ok I was riding yesterday and I began to notice that my bike seemed to be getting very sluggish. It was almost as if i was trying to pedal with the brakes applied. After checking to make sure that the brakes were not rubbing I came to the conclusion that it must be the rear hub. However I have only had this Shimano M535 wheelset for a couple weeks. So I was wondering if anyone knew of any other parts of the bike that might be in need of service. The only other thing I could think of would be the bottom bracket. Thanks alot

You can spin the wheels and tell if they are coasting well. In order for you to feel bearing friction while you are riding, they'd almost have to be seized. You can easily feel this at the wheel by hand. For the rear wheel, you can get the best feel by removing the chain so you are not seeing cassette mechanism friction. Same issues with the BB or pedals - the bearings would have to be nearly frozen to get what you describe and you could easily feel it by hand. Your two most likely culprits are soft tires and dead legs.

As posted before, make certain that it is infact the rear wheel. Open the brake QR, and spin the wheel. If it stops spining really quickly, then you have an issue with the hub. Drop the wheel out, and spin the axle by hand. Also check the freehub. If either is sluggish, then you need to adjust the bearings. Might as well open the whole thing up and regrease while you're at it. Once the bearings are out, check the freehub fixing bolt. I have seen them loosen and push against the bearings, causing binding. Tighten that bolt, and reassemble. If that doesn't work, then take them back.
