Installed mine today. Was pretty easy. Took about half an hour. Then again, I've also taken off my plastics so much I could do it blindfolded
I really felt a difference in the steering. Extremely lighter.
Thanks Karen and RS for getting this together
For the record, this was my stem after less then 10 rides.
Notice the pitting. I've never seen such a highly used part so horribly designed for maintenence.
