Deity Components Carbon 35mm handlebar, 35mm CopperHead Stem, and spacer kit. The bars have a 25mm rise and better vibration damping vs the Pro Tapers. The stem is just a nicer stem and matches the rest of the bike. Same with the spacers. Also ditched the dropper post for a Control Tech and Hope Tech post clamp. Now I just need to find the Fox DHX rear shock that I want. Love this bike, best in my stable. So far on a very slight incline I’ve hit a non GPS verified 39 mph pedaling like a crazed gerbil on crack. Definitely the fastest bike I own.
