Great cog. Yuge. I know cogs so well, the best cogs, this is a great cog - trust me.

Worst ninja star, horrible, nasty ninja star. Too heavy. Who uses this as a ninja star? Nobody.

Probably one of the lightest cogs i've ever used. All others that say they're light weight still have some heft to them but none have yet to come to par with this cog. No issues with performance or installation. Installs smoothly and turns smoothly without a gear crunching sound due to the perfect round shape that cheap cogs lack and have minor imperfections that cause chain binding and grinding sounds. My top pick for anyone looking for a lightweight and durable cog to upgrade to.

I used to used a Gusset 15t Cog, but then I switched to the Aventon cog and I'm happy with it. I've switched it to a couple wheelsets I've had. The aluminum teeth on it have not frayed or worn down at all. I've been riding 48x15 and it's very responsive I have that cog on my Mavic CXP22 wheelset for now and the cog sounds nice asf because of the vibrating aluminum against my Izumi Toughness Chain. It's an all around great cog in my opinion.
