Hubs need servicing or?

Noticed lately, when fixing a flat or whatever, spinning my rear or front wheel that they sound bad and come to a stop sooner than they used to. Iím guessing something is up with my hubs but have never taken hubs apart myself so donít know for sure. I have formulas front and rear that come on the Dawes from bikesdirect. Said on their site they are sealed. bike is about 6 months old so maybe itís time for the hubs to be serviced? Is this something I can do myself without special tools or should I just take it to a bike shop? What would be a fair price for a shop to check em out/fix? Thanks.

First verify that your hubs have cartridge bearings or loose ball bearings because both can be sealed and Bikesdirect misleading. There are lots of videos and articles on how to service either kind of hub. You will need special tools either way, cone wrenches for loose ball hubs and some kind of bearing press (there are DIY threads here for this) for cartridge hubs. That said, all the cartridge Formula hubs I have had also require cone wrenches to service.

Thanks. Not sure how to tell if the hubs are cartridge or loose but found this thread https://www.bikeforums.net/commuting/1040228-dawes-streetfighter-review.html with some pretty good pics of the hubs. Can anyone let me know?

The bearings in the link are loose ball bearings. Of course, you'll want to verify that your hubs actually match those. It wouldn't be unusual for BD to spec different hubs or wheels at some point.

Those are loose ball hubs. You will most likely want a 13mm cone wrench for the front and a 15mm for the rear as well as a 17mm combo wrench or two. As for grease, you will get many many different opinions, I have $5 tubs of molybdenum grease and marine trailer bearing grease, either works great.

The only thing I have that you mentioned is the grease so I will probably go the bike shop route. If they try to charge me an arm and a leg Iíll probably fork over the cash for the tools and do it myself.

At the very least doing it yourself would be a good learning experience. I have serviced a lot of loose ball bearing hubs before, and the only fiddly thing is getting the right bearing adjustment after cleaning out and re-greasing. The grease you put in will probably be better quality than what's there too. Just go slow and make sure you don't lose any bearings
