Great service, great product!

The quality of the product was immediately apparent, even before I had a chance to use it. Simply seeing and handling it straight out of the package, I could tell how beautifully crafted and meticulously finished it was. After actually using it, that impression became a certainty.

The design is equally impressive. The consistent black aesthetic gives it a sophisticated and cohesive look, while the minimalist approach makes the overall design feel complete and refined.

What impressed me even more, however, was the exceptional service I received after placing my order. From the thoughtful follow-up and care throughout the process to the beautiful packaging and handwritten letter, every detail was filled with genuine hospitality. It was far beyond what I would expect from an ordinary online purchase, and I was extremely satisfied with the entire experience.

I am Japanese and lived in New Zealand for about two years as an international student around 20 years ago. This experience reminded me once again what a wonderful country New Zealand is, and how warm and thoughtful its people can be.

This was not simply an online shopping experience. It was a genuinely wonderful experience from beginning to end.

You may need a specialty lockring for 12T

Good and strong sprocket, but please be aware that if you buy it in 12T you may need to buy a special lockring to ensure the chain can safely engage the teeth. I would double check with 13T and 14T if you're eyeing those sizes. Had I known that I would have ordered the lockring at the same time, but instead have to wait for the part to arrive from NZ - might be helpful to put that in the product description.

Hi Michael, thank you for your feedback! I'll add this into the product description. It isn't a common issue as the majority of our audience don't use Lockrings on the track. Out of sight, out of mind I guess.

A solid sprocket.

It does what it’s supposed to do and is noticeably quieter than the previous sprocket I had from a different brand.

Great product, quick shipping!

Got 12t & 13t sprockets, I thought it would take longer to get to the US, but was very quick! Great product, easy to pay the tariffs, nice packaging, care in some nice bags that will ensure they don’t get banged up. Velobike will definitely be a go-to for ordering well made parts!

Surprised how smooth the cog felt.
Really like the presentation and small branded bag included. Little touches really matter and you can this is a premium product. Would buy again.

Only missing a 17t and then my set will be complete!

Durable, yet lightweight these sprockets are smooth to install and paired with the Velobike lock-ring, add both performance and looks to my drivetrain. Designed and fabricated with a high tolerance, they stay true and don't wear down quickly like other brands. (The pouch they come is is also perfect for pins!)

Great cog.

Since installing my first one of these cogs on my bike a year ago, I saw an immediate increase in hot babes winking at me. I now use these on both my bikes.

Perfection. .

I recently picked up the Velobike Track Sprocket, and honestly, it’s been a game-changer for my rides. I was a little skeptical at first because I’ve tried other mid-range track sprockets, and they’ve always fallen short somehow. But this one just clicks — no pun intended. It’s machined from high-quality steel, and you can tell Velobike put some thought into making it durable without adding unnecessary weight. The engagement feels smooth, and it hasn't given me any weird chain skips or that annoying wobble you sometimes get with lower-end sprockets.

It also gives off this solid, "built to last" vibe, which gives me peace of mind, especially on longer rides. I can't say it’s made me faster (yet), but it definitely feels like it transfers my effort more efficiently, which is all you can ask for. If you're serious about your track setup and want something reliable, I’d say give this sprocket a go. It just feels right on the bike.

Great value, smooth running

Excellent value, these are quieter and smoother running than NJS certified cogs from a big name OEM. For practically the same price it's definitely worthwhile to support Velobike who supports the niche track racing community!

Another great one!

Everything VB produces is the highest quality. Thanks for finding this gap in the marketplace and filling it with the best track gear money can buy.

Nicely finished and runs quiet

The thread was a little tighter than I was comfortable with so I took it back into the shop for him to have a look at. He ran a thread chaser through it after which it fit perfectly. I'm pretty sure it would have fit fine just gently but firmly threading it on without any need to clean the thread. Just my first time changing a sprocket so I wasn't sure if I'd cross-threaded or had the wrong pitch.

Best sprockets in the game!

I love Velobike sprockets, as they are beautifully engineered and finished. I have an 11 tooth for off-season 'big gear' sessions - and keep a set of 12 to 16 tooth for my racing days.

Long live Velobike!
