>>1078317If you know a lot about bikes, you can get a retro bike, but if you don't, get a newer one.
First of all, you need to know what you are buying. If you won't be able to identify which parts are fucked before purchase, you will either be riding a underperforming bike, or get tricked and end up having to replace a lot of shit anyway.
Some retro parts can be renovated, some can't. If you know how to disassemble them, you can do a lot to improve brakes, derailleur and some other things. There are also those that can't be repaired in any way, things like chain, cables, casette, etc.
If you like working on such things, having a retro bike is a lot of fun. If you buy it and find out that you don't, it's just gonna be a lot of dissapointment. The pros is also the fact that you can gradually invest into it replacing the things that you consider worth the money, eventually ending up with a very well performing bike if you know what you are doing.
