I know this has been discussed, I did do a search, but I have a two-part question and the second part doesn't seemed to have been answered in past threads.
I have a few year old entry level road bike made from Reynolds 631. (It's a 2004)
I noticed that inside of the seat tube there is some rust forming. I also noticed some around the rear brake mount. My bike lives inside but it has been ridden in the rain plenty. I assume that it is superficial simply because of the young age of this bike.
Here are my questions:
If I take to the shop that I bought it from, what are they likely to do? And how much will it cost me?
I want to save this frame. Is this something that needs to be taken care of immediately?
Thanks to anyone with the patience to answer yet another rust question.
