Post by: CoCo on 28 August, 2017, 08:00:53 pm

Does anybody know what stock chainring sizes Challenge fitted to the Hurricane?

If a 100" gear is the old standard top gear.
Then working backward from a 20" wheel and an 11t sprocket, you need a 60t chainring.
So as a pure guess something in the range 56t-65t.
But probably edging toward the 65t for a 110" top.

A 40-60 double was standard on various Challenge models.
