Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Bad Bearings?

Yesterday I was riding my single speed beach cruiser when a horrible, grinding noise came from my rear hub. It progressively got worse as well as becoming more difficult to pedal. I've had the bike for a few months but I suspect I either have a bad bearing or there isn't enough grease packed in causing the noise. Any thoughts. Also, anyone know of a good site for instructions on servicing a rear hub?

The bearing cage may have broken due to lack of (or contaminated) grease.
If the cage has indeed broken you will have loose bearings and shards of metal in your bb.
Stop riding until the bb can be opened up and inspected.

I did that same thing with a 1990 Buick LeSabre. $700 and a new transmission later, what did I learn? Anytime a vehicle makes a grinding noise, stop moving (unless you are fairly certain that it is only the neighbors trashcan dragging underneath you).

Sounds like a shot hub.

You may want to post in Mechanics forum.

You probably just need new bearings.

Bearings or axle. Get it off the bike and open (sheldon, etc will show ya how) and replace the mangled bits.
