Why is that optimistic? That's their 'price' from the Manchester Velo Assoc (or whoever is selling the old track).
They go up from their too. If you want finish line it's £40.
Some people have bought it too and why wouldn't you, if you'd won a national/world title there or raced many times.
Kinda cool I reckon, but never having raced there I'm not gonna buy any.
