The spacer works as advertised and is a must have if you have a Giant bike with Overdrive 2
This spacer is exactly what it says. The special thing about it is that the good folks at Mac-Ride make it. From a Giant owner who has painfully shopped for a stem and headset, this part is greatly appreciated.
YES! It's hard to get a review on an accessory, but Ryan just helped us BIG TIME!
