Shimano Dura Ace Cog 16 Teeth Track (Grey)

i put this baby on, greased my chain and it was good to go.super smooth cog i only hear my tires touching the floor.just be the name shimano dura ace you already know this is an amazing product.pros- light, smooth, NJS approved.cons- nothing.i recommend this cog to riders who want to upgrade their cogs and that dont have 120 bucks for a euro asia gold medal cog.ive riden euro asia god metal cog that cog is amazing, smooth and 100% quiet but this dura ace cog is just as good only thing is that the dura ace makes a noise but a good noise, meaning you hear the drive train but it sounds really nice.

Product worked perfect! Correct width and all. I have ridden a EAI Deluxe cog and it's great as well. I actually prefer it because I like the finish more and its the same price. Functionally, they are both the same, take the same amount of wear over the same time. Genuinely good product and good price.

I expected more from shimano. Cog comes lose every few days. Chain skips and super noisy!! Never buy this crap again!!

I bought this for a fixed-gear conversion that I'm working on, and it's going to be one of the toughest pieces I've installed on the bike so far. Dura Ace is a trusted line from Shimano, and I only wish that I could afford more Dura Ace parts.

Installed this on my bike and it's held up very well..love riding fixie and having the option to just swap it back to normal when i want to take my daughters on a bike ride...

Beautifully finished, smooth threads

Shelling out the money for Dura-Ace drivetrain parts for your fixed gear is a pretty good idea. You can't find tougher parts. They are going to last. This cog is lightweight and dead sexy. It works perfectly with my Dura-Ace lockring.

Shipped in the Shimano box and arrived in perfect condition. The cog is clearly high quality and made a noticeable improvement on rides.
