Very fixable. Best done with a pair of tools made for the job. It can also be done yourself, but is a bit more complicated to do. It might be pricy at a bike shop, but hopefully there's a co-op (aka bike kitchen, or community bike shop) where you live, where you can either rent the tools for a low fee, or have them do the job.

BTW- add your city of residency (or a nearby city if you're concerned about privacy) to your profile so folks might direct you to local resources.
