Must have

This is my 2nd one I bought, this time for wife's bike. Much more comfy to ride.

Riding made better

Made riding the cannondale much better. Why cannondale is aware of this complaint and they dont do anything is terrible but glad there is a company that helped with the problem of the handlebars being to low.

Female section of extension too short!

The female section of the extension is too short! Handlebars these days are 1 3/4 deep where they connect to the forks. This extender's depth is only 1 21/32 inches, 3/32 of an inch too short. I'll return it rather than buy a headset spacer.

It was the the correct diameter, but I needed a wider spacer to fill the gap.
