From the eMailbox: Servicing a crankset

Q: Over the winter, I like to keep my bike running smoothly. I can do most of the repairs myself, but the crank is one part of the bike I haven't worked with. Will your bike mechanics at Century Cycles work on just one component -- like take apart the crank and check the bearings?

A: Sure, we can do just the service that you'd like. Does your bike have an older-style bottom bracket with loose-ball or caged bearings? If so, then we'd have to take a look at it once it's taken apart to see what kind of condition they're in and whether or not they need to be replaced or just cleaned and re-greased. It would be hard to give you an estimate until we see it.

Most newer bikes have a newer cartridge-style or sealed-bearing bottom bracket. If that's the case with yours, then for about $20-$25, we can take off your crankset, take out the bottom bracket, clean and re-grease the threads, and put it all back together. If the bottom bracket is not in workable condition, then a replacement could run about $25 and up, depending on the brand/model/type.

Feel free to stop into any of our Century Cycles stores and have us take a look at it. The turn-around time will vary from store-to-store, depending on what else we have in the repair queue at the time.

  1. Bottom bracket bearings are the most heavily loaded bearing on the bike, and sadly the most overlooked as well. It's one of the first things to check when evaluating a bike's condition. Replacing a bad one makes such a difference!
