I needed a shorter stem and this fit the bill. Plus I wanted some orange to match other parts on my bike. Stem is great, has held up to a lot of abuse. It's much lighter than my older stem.

I was however a little let down it didn't include the top star cap.;

Pricey little booger... But well worth the pick. I put it on a 2019 Evil The Wreckoning that I built from the frame up... and it looks fantastic with the aluminum purple pedals and bottle cage. I looked all around for a less expensive stem.. but I'm happy with my splurge.;
