Seeking advise. I’m looking for a less expensive trainer that will fit my Felt VR40.The bike does not have QR Skewer.
Today, had my first Zwift ride but the bike popped out of the trainer; it is skewer related. The skewer that came with the Ascent Fluid Trainer is too short. We bought a longer skewer but nuts don’t seem to fit as they should in the Ascent Fluid Trainer. We thought it was tight enough but the riding/ vibration just seems to loosen to quickly.
Sure, the unit was only $110. I’m not interested in spending much more. Perhaps $200. Do any of you have a Felt bike? What kinds of trainers do you use?
I’m not a racer, just an enthusiast who has winter sport interests so spending lots of money on this will take away from lift tickets. 
This has been one of my most frustrating fitness projects.
I have a Felt S32 and have use a very low end trainer (I think it’s a RAD) and a Tacx Satori Smart and have never had a skewer issue.
Wait… your frame uses a 12 x 142 mm thru-axle. You can’t (to my knowledge) just shove a standard QR skewer like the one that came with your trainer into it and expect it to work.
Higher-end trainers are often convertible to work with thru-axles or QR skewers, but I doubt there are many options at or below $200. There are a number of reasons why spending more and upgrading to a controllable smart trainer is a good idea… but that’s a topic for a different thread.
If you just want your bike to work with the trainer you’ve got? Try looking here:

Unfortunately, Felt bikes aren’t included in their axle selector drop-downs, so you’ll have to do a bit of extra work looking at your thru-axle to be sure you get the correct one for your application, but it shouldn’t be very difficult.
Good Luck!
