I wonder if any folks here do their own maintenance other than simple tire changes. Admittedly, I’m a little rough on my road bike; I probably get less than 3,000 miles on a chain. I didn’t know this at first (just was noticing sloppy shifting), and the rear sprocket had started to wear due to chain stretch, and needed to be replaced,
After this morning’s ride, I was replacing the chain (I finally bought the tool to measure chain stretch and the extractor) which is not a difficult job. Much to my horror, I discovered the crank was quite loose. I mean shake it up-type loose. I know I had the dealer replace the crank bearings last year. So I maybe have 4,000 miles on it.
Perhaps this is not abnormal, given the hard road riding I do. No complaints, just wondering how often folks check and/or replace their bottom bearings.
