Due to the age of the bikes I sell components for, some parts may be temporarily or permanently unavailable. I am always in the process of updating and verifying our parts lists. I apologize for any inconvenience this may cause. I am in the process of updating and soon changing the website. Some of it is updated, more will be.

Updated Prices Dec 8. I try to be accurate, but am quite capable of messing up!
