I’m upgrading from a dumb trainer to a smart trainer and decided on the Jetblack Victory. I comes with a zwift cog. Some basic questions to see if I can get my 1 by 12 SRDRAM Eagle GX based mountain bike working with this, set my expectations, or see if I need to cancel order. I plan on NOT using zwift, only TrainerRoad.
First, it’s incompatible with XD (XDR?). The trainer’s instructions state there is an adapter, but their support replied to my email stating there isn’t one because of demand for the XDR. Sorry a little confused on XDR vs XD for getting this to work on a trainer.
With the zwift cog, Is it correct I can only use this in ERG mode on trainer road? Again since I’m new to smart trainers, I think I would want to use ERG mode some of the times, but not all of the times.
Since XDR adapters don’t exist, Can I use something like the SRAM Pg-1230 Nx Eagle 12-Speed Cassette? It looks like it’s Shimano/splined-drive compatible hub, but SRAM Eagle drive train compatible.
Is there anything else I’m missing? Does jumping from one cassette (trainer) to another (wheel) just require maybe a little derailleur adjustments? Any sort of extra wear and tear on chain?
XD and XDR are slightly different, you can put an XD cassette on an XDR body with a small spacer, but you cannot put an XDR cassette on an XD freehub (too short).
Not necessarily your main concern but just helping to clarify that difference. Chances are because of that when you asked about XD they mentioned not having XDR parts since for their stocking purposes XDR and a spacer would make sense vs 2 skus.
their AU site seems to be showing a body available, maybe just not shipping globally? That being said seems not likely they designed their own freehub and are more than likely using something off the shelf you can find. If you possibly can research people replacing them and can then find out say what hub that body fits then you can figure out if that hub has an XD/XDR option. I realizing having to find your own parts isn’t appealing when you can just buy something else that works off the shelf but just wanted to mention that. I tried to see real quick if someone had found a compatible solution but didn’t see anything.
Sorry can’t help you on compatibility of some of the other cassettes as I have not dealt with them.
If you use that, you then cannot use a cassette or change gears manually. You need zwifts shifters and a compatible trainer that allows virtual shifting.
The only apps that natively allow that is (wouldnt quote me on this) Zwift and Rouvy. TR there is either ERG mode or single speed mode with ERG off.
There is a Qdomyos app to act as a middle man for other applications but not sure if its any good or how it works.
Can you not just use a 12 speed cassette that fits on a ‘normal’ (11 speed) freehub? Sram at least have an 11-52 option that works on the traditional freehub. Afaik you only need the XD freehub to fit a 10t cog.
Actually just realised that you mentioned that:
Yeah, I think that should work. I’ve got that cassette on my bike, on an old freehub.
You can use an NX cassette on the Jetblack freehub. You probably don’t need that low of gearing though. I run a 12 speed sunrace 11-30something on mine because I usually have my 2x road bike on there, but it works fine for my MTB too. I think the most annoying part is smaller front rings kinda feel weird just because of the lower flyweel speeds, but that may or may not bother you.
If you are only using ERG, just use the single speed cassette that ships with it though? No need to put a 12 speed cassette on it.
I saw it on their AU site. Either they don’t ship to US or it’s discontinued.
Email from their support “ we currently do not offer a SRAM XDR freehub for the Victory trainer due to low demand, as most users prefer to utilise the trainer with the Cog and Click. The Victory trainer specifically requires a unique XDR freehub, which is why there are no compatible aftermarket options available at this time. ”
I’m going to go with the SRAM Pg-1230 Nx Eagle route based on others’ replies.
