Basically the axle of the neo doesn’t pivot so it’s your frame that moves against the resistance.
You can install some plastic washers which will lesson the strain on your dropouts.
You can also loosen the skewer slightly to lessen the pressure.
I’m using a carbon frame and have not had any issues so far. That said I’m not precious over the frame as it’s a spare.
The Rizer pairs seamlessly with the Neo.
There is sometimes a bit of lag between it adjusting the angle compared to what Zwift is reporting but it’s not that noticeable.
Thank you Stuart. Sounds like a go then. It’s an old bike I’m using so not worried about the frame. If you have any details on the nylon washers that will be great, no problem if not, I can find that out thanks again.
They don’t need to be big. Maybe 3cm diameter with a hole big enough for your skewer to go through. One each side of your dropouts so 4 in total. I’d put some grease on both sides too. Nothing technical, just to help the frame slide better.
I used 3x 10x22x.01 washers between bike and frame, greased.
Then similar roller bearing between outer frame and trainer screw/nut (5mm width but no issues as outer frame). No issues so far, however, using an older alloy frame which I’m unlikely to use in the road.
About 3mm thickness, I got a used alloy frame to build as a trainer bike. There should be enough axle on the trainer to get me at least half of the drop out on the tacx axle. I ordered both 9 and 10mm. Just got the rest of the components for the trainer bike so this will be going down very soon.
So I used the above thrust washers but had to get some new endcaps made for the Neo. This way I can ride without worrying about slippage during a sprint. Works beautifully. I did need to spread the dropouts of the frame a bit to compensate but I chose a frame that flexes nicely with this set up.
Peter, perhaps you could provide some more photos of the parts and modifications you’ve made?
I too had contemplated a similar project. The perfect solution would be Tacx offering new thru-axle adaptors for both drive and non-drive side that included a bearing to allow the outer section of the adaptor to rotate.
