I'd like some help with a build I'm eyeballing at the moment. I have a bare Peloton frame circa 86 that I want to put together for exercise and fitness purposes. I initially wanted to build it out with new(er) components, but the cost just doesn't justify it right now. I'm looking for a more budget build but don't know much about components pre 2000. My only absolute is a Brooks (type) saddle. I'm okay with DT shifters, 5, 6, or 7 speed, but not really hung up on either. I've thought about buying a cheaper complete bike from ebay or craigslist and cannibalizing it, but not sure what to look for. I'm looking to keep the total project under 300. Any help would be appreciated.
