>>1716705like it really is worth considering, if the price is $1000, and you have to overhaul it and replace tires and shifters, you could have this for the same money.
Which won't even be better by every metric but will be new.
Only a very specific kind of race bike is still worth $$$. Most of them are next to worthless for their intended purpose which is high performance. Their price should be less than an equivalent new bike. Fairly and generally, half. At least.
