1-1/8" Sealed Bearing Threadless Headset

Great quality at affordable price

I installed this headset myself and the difference in smoothness when turning the handlebars from the previous one was definitely perceptible. This headset is super smooth. I opted to put the VO logos on the side, and I appreciate that a logo was even etched on parts of the cups inserted into the head tube- a sign of quality. I recommend.

I've yet to install, but looks great.

Excellent Headset, Good Price

I've had an identical VO headset on another bike for well over 25.000 miles and it's still in excellent condition. The split crown race is a great feature that makes installation much easier.

Excellent Headset

I installed this headset on a Litespeed road bike to replace the original FSA. Installation was very easy, particularly due to the split crown race, and it has been very smooth and solid with 18,000 miles so far. Very pleased.
