Hi guys, would like to ask for your opinion. For the first time I got a rusty chain: On Friday we were riding a nasty single track and at one point my master chain link snapped - the chain went down to the mud. We replace the link , installed the chain but there was a lot of mud on it. Rode another 50+ miles - in the evening we got hit with snow and I trailed the bike home Saturday night in rain and snow. When I woke up this morning the chain was super rusty and there was some rust on the rear and front sprockets as well. I am assuming all the mud, sand etc. wore of the protective coat and the rain/snow did not help - but it happened so fast. I cleaned the sprockets and chain with WD40 and nylon brush, wiping it clean. But there is still some rust on some of the links and it looks like there is still some gunk on the inside rings. The sprockets look OK Does it mean I need to get a new chain? Or is it just a cosmetic issue and I can keep riding as long as I lubricate regularly? I would like to avoid shorten live for the sprockets. Chain is only about 9 months old, with ~ 1200 miles. Bike is Husky 701.
