XD-R is for road, primarily for the new AXS 12 speed groupsets. XD-R is backwards compatible with XD, using a cassette spacer. This is similar to the Shimano 11 speed/10 speed spacer and cassette compatibility. You would know if you need XD, but if I were you and need XD, I would just get XD-R and put a cassette spacer on it.
XD is for road and mountain. Some 1x bikes (gravel, CX, etc.) run SRAM XD cassettes. You can’t miss this, as the cassette is screwed onto the freehub. XD-R is the same way, just that the XD-R body is a tad longer.
Campagnolo is for Campagnolo drivetrains. You would know if you have this.
SRAM uses both HG and XD, so you need to know what you have. XD would normally be on the MTB/1x Gravel/1x CX type drivetrains that run 10-50, 10-42, etc. The easiest way to tell, if you have a lockring, you’re not using XD technology. If you have the smallest cog as 11T, you’re most likely not XD, but the lockring is the dead givaway as XD and XD-R do not use lockrings. You use the same tool and screw the cassette onto the freehub.
For your groupset, assuming it’s 11 speed road such as Force, Red, etc. You are most likely using a Shimano HG freehub, which is probably what comes default on the trainer.
I have dubbel checked it and it is one like that link.
So I just buy a new one? Or are there better hubs/body’s available on the market?
I also thinking of buying a new casette and a new chain for the smarttrainer… Good idea ?
Edco cassettes doesn’t come with bikes as OEM, that I know of. Regardless…there’s a number written on the freehub body. Take off your cassette, and look for the same one.
The Tacx Flux freehub body that comes with the trainer is the Edco one (I’m not sure if this is what you mean when you said Edco) and is compatible with both Campagnolo and Shimano. Take off your cassette and take a look at what you have.
It is technically called a freehub body. A hub is the entire thing in the center of your wheelset that the spokes connect to. The freehub body is the thing the cassette attaches to, and it is part of the hub. It is sometimes referred to as a cassette driver.
Try contacting Tacx? It’s hard to say what the problem is until you disassemble and take a look. It might be the freehub body (the pawls may have seized for some reason, or it may need to be lubricated and not replaced, or may have some debris there), it might be something else entirely as well. I’d hate to waste the money. If you don’t need the trainer for some time, you can try to pull out the freehub body and see why the pawls are not retracting.
Contact Tacx. If you’re under warranty, they’ll ship you a replacement (Shimano). If you’re not under warranty, they still might ship you one for free. Worst case, you can buy the replacement parts on the Tacx website.
My Neo1 Edco freehub died last month or was it the month before. Anyway, after a couple email exchanges they sent (Netherlands -> Taipei) a Shimano replacement freehub under warranty. It arrived two days later.
I want to use my eagle cassette on the Tacx neo smart 1 can I use any companies XD-R work or will I have to but the tacx version T2805.81 SRAM XD-R or will this one workhttps://www.evolutioncycles.co.nz/Product/293596/sram-red-axs-xd-driver-freehub-body-with-bearings?variationId=292847&gclid=EAIaIQobChMIhYqVgOrI5wIVwzUrCh0_0QFoEAQYAyABEgIN-_D_BwE
