Hello, can anybody tell me if the Campag Ekar 13spd chain works with the zwift cog?? I already use a zwift cog and am thinking of buying a bike with Ekar 13spd. However compatability with the zwift cog is a must for me Thanks in advance!

Doubtful, but I don’t have an Ekar bike to check so perhaps someone who owns one can say. Official word is 8-12 speed. [image] Zwift Hub One Compatibility Red XPLR 13 Zwift Equipment Hello @Leo_S1 welcome to Zwift forums. Shuji at Zwift HQ here. The Zwift Cog that is equ…

If you’re not switching back and forth between outdoors and indoors from day to day, you could just use a wider chain for indoors though, the Ekar crank certainly won’t mind (plus you can get a reusable 13s Campagnolo quick link for the Ekar chain).

This… or you may want to ask around the campy bike forums out there. Is there a chance you could replace the stock Cog with an ekar cog? That said, I have no idea if you can buy such a thing. While I know you can’t mount a full ekar cassette on a campy standard freehub, I don’t know if this also …

Hey, thanks for the input. The idea of having a designated wider chain for indoors is not such a bad idea. However, I do switch back and forth a bit. Anyone have a 13spd chain that they could measure the internal width of for me? I’ve googled about, but no success on that dimension

GPLama has a video up on his YouTube channel where he measures the Zwift cog to 1.72mm (scroll to about the 3min point of the video). Spoiler alert: It’s too wide for the Ekar chain … BUT you can switch the cog if you can find something narrow enough.

Hey, thatnks heaps for that tip! Seeing how simple the zwift cog is, I could just buy a 14t ekar cog and put it on. …or just machine down the zwift cog a few tenths of a mil on the lathe at work :wink:

Did you ever figure this out? I’m in the same boat

It would definately be nice if they could release a narrower cog so that you can use it with narrower chains…. But I think using a wider chain is the only answer currently - unless you file down the cog.

I think Zwift could/should release a compatible 13s cog soon. It can’t be too hard to source someone to make a single steel sprocket in the necessary width.

Sadly what I am going to do on my new SR WRL 13 bike is use my old 11sp campag cassette and use the middle 6th sprocket on the trainer and then put my 13sp bike into 7th gear Should work and be all aligned Or I can just reuse my older11sp chain indoors Saves me buying a new cassette and N3W hub j…
