Obvious newb question

52/18 is pretty high.
depends on the person though, it takes a bit of trial and error before you find the prefect ratio
i run 48/20. spin to win man!

if it's a 144 bcd chainring you're looking for. i might be looking to change mine for something smaller so gimme a shout. it's a reasonably new 48t miche primato 1/8 track chainring.

big up 48/20
