I have a fixie that I got from a friend, and really wanted to use it as my trainer bike with my Zwift Hub. I have the Zwift Cog single gear on the trainer with this application.

These are a very high quality adapter that will hold a big fella like me with ease (230lbs). They make it to where you can mount the bike on your trainer. What else do you need?

I will note that since the Zwift Cog has a goofy little plastic spacer on it, you have to get your own metal hub spacers to put on there so that the screw doesn't hit that piece and it reduces the overall size. I'm sure this is not an issue with most trainer setups, the Zwift cog is just a super goofy little piece with that extra plastic.

Very easy fix with some quick collaboration with my local bike shop! I also had to slightly lengthen the chain, but that's also easy and was expected.

Thanks Velobike!

The thing I noticed as soon as I fitted the Velobike cogs to my track bike was the reduction in chain line noise. Less noise means less friction, which means more speed. That's speed for free. How good is that!

The single speed adaptor was of high quality and extremely easy to install onto my Redbox trainerafter watching the helpful video on you tube by velobike. The transmitting was flawless too and I would highly recommend this product along with velobike.

muy buena calidad

Bought the 10mm expander so I can add another spacer underneath my stem. Bottom half clamps on steerer itself and top half clamps to the expander. Haven’t had any issues and already rode the bike multiple times.

Love it when you can keep awesome working equipment going! Belt is hard to find too.

I’ve been searching for a quality 160mm stem for a while, and I finally found the Longboi stem from Velobike. An added bonus was that it received it 2 days after I ordered it. Great product and even better customer service. Thanks

Handling is good, and the aero position is easy to take.

정말 해외배송이 이렇게 빨리 도착할 수 있나요? 주문하고 300mm로 교환하고 싶었지만, 받아보니 너무 맘에 들고, 핸들바교체 후 속도가 엄청 좋아 졌습니다.
채팅도 엄청 빠른 속도로 대응해 주시고 정말 최고 였습니다.
너무 감동 받았어요 다음에 꼭 다시 구매 할 겁니다.

If you ride a track bike, and you train indoors through the winter, this is an indispensable piece of equipment. It's very well machined to tight tolerances and works exactly as advertised. Installation is simple and only takes a minute.

Best Upgrade made to the Track Bike, 100% worth it!

Prompt delivery, smart box.

I bought these to replace a more endurance focused bar. The shape is great- allows to really get on the bottom of the drops and do standing start without wrists bumping into the bars. Bend is deep enough for my hands. zero complaints

Awesome. So much fun to print and so handy to check chainrings will fit!!

Epoxied into an alloy steerer tube for a Fox 34 and it hasn’t budged since. Good quality product that does what it’s supposed to.
