Extrovert drivers

[belcher]

my recently acquired s/c apex still has the factory drivers. I want to put on extroverts. My question is if I go to 2.86 pitch how many teeth do I need to keep the gearing the same. I want to put on the ripsaw 1.5 137. They don't make the ripsaw 1.5 136 anymore. Thanks

8 tooth extrovert 2.86 drivers is what you need for the same gear ratio as the stock 2.52 drivers.
