I don't know about that.

It depends on how clean it is. A 710 frame is a really nice, quality frame with 531 frame/fork and stays.

As far as what's "bad." IMO, taking a REALLY clean frame and changing things that can't be changed back. Cutting stuff off, drilling into it, unwarranted painting...

Yes, it's "your" bike, you can do what you want to it. But at some point it won't be "your" bike. For all the "what kind of mystery frame" threads as we have here (and this is just one forum- and this is just the people that ask)- tons of ill advised stuff happens to bikes in the name of "it's mine."

Rather than taking "A" bike that's "yours" and making it into something that it's not- Chances are someone wants the bike you've got, and someone's got the bike you want. Get the bike you want instead of ****ing up a perfectly good bike.

NOW- the idea of changing components isn't a "bad" thing because it's totally reversible. Hell, that breathes new life into an old bike.
