I cut my hair twice last year, taking off a total of 24 inches or so; and kept both braids. We weighed them together and they totaled, dry, approx. 17 grams.

Personally, I'd rather save the money at the hairdresser and keep the long hair if it feels comfortable enough when you ride. No point in cutting it unless you *want* to.
