Smart trainers and the V20

Have been using a Wahoo Kickr Snap (wheel on type) with a V20 with caliper brakes regularly since March 2019. Hopefully, I will be able get back on the road with the V20 this summer, to compare with my performance on the trike.

I've had no problem using a Saris/CycleOps Fluid2 wheel-on trainer with my S30. And yes, you can orient it properly so that the trainer spin direction is correct. Just locate the resistance unit under the front of the bike. It does help to use a road wheel with a 130 mm dropout width so you can use the prescribed skewer, but you can work around that issue if your wheel is wider. I keep an old spare 130 mm road wheel with a trainer tire permanently mounted for use on the trainer.

I have an elite also. Works w both S40 and V20 w discs. Also have used my Kurt kinetic wheel on trainer but finding an appropriate skewer was a challenge

Do you use your regular skewer on a direct drive trainer or buy one specifically for the job? the skewer that comes with the kickr core is shorter than the one on the Vendetta. I've searched some of the threads but I haven't found the definitive answer.

Took lots of searching but a tandem skewer did the trick. Actually just checked my trainer set up. Forgot that I have a board under the Elite’s front feet to rotate the trainer body slightly to eliminate the disc problem

I ride my V20 with either a KickR Snap or a Kinetic Road Machine. I made my own skewer for the front using some M5 threaded road and two skewer nuts. Work good. I have not had good luck with the Snap (2016 model). I just recently bought a new resistance unit for it because Wahoo will not sell the $10 circuit board that failed so I had to pay $300 to replace something that was actually defective from the get go. Tried to get the issue resolved when I first bought it but Wahoo refused to believe that it was their product. They blamed my computer, my WiFi, my house, etc. Needless to say, I can't recommend Wahoo. The Kinetic isn't a controllable trainer but it is consistent from ride to ride and with the Inride sensor, Zwift considers it a smart trainer.

I recently got a Wahoo Kickr Core. The skewer wasn't long enough, so I used mine...

That is a wheel off trainer so the stock skewer is perfect. Wheel on trainers are the problem because the ends of the skewer need to fit into the cups on the trainer.

I have a wheel-on "dumb trainer" and made my own axle for use with it. A piece of 5mm all thread cut to length with a trainer skewer nut on both sides. I got the idea from someone on this forum, I'm pretty sure.
My only issue is that clamping the bike in the trainer makes it shift poorly in the two smallest cassette cogs. It shifts fine on the road but the chain drags like the cable is out of adjustment when it's on the trainer.
I tried to fix it but don't want to jack up my shifting IRL to make it work on the trainer, which I only use as a last resort if there's too much snow/ice to ride outside.

It sounds as though something is getting in the way of the derailleur/ getting all the way out. If it is like mine, the spring in the derailleur is what pulls it out to the smallest gears so if the cable is curved tighter, or something is restricting the derailleur movement down or out then it can get grumpy even if the everything is set up correctly so look for something that puts some pressure on the derailleur or its cable. It could be as simple as cable routing above vs. below where the trainer attaches.

Routing and stuff is ok. I think part of the problem was that the skewer nut wasnt sticking out far enough and the trainer was basically clamping on the outside of the fork on the drive side.
I put some washers behind the nut so the clamp could grab the nut better and it cleared up the problem for the most part.

Works fine with a Tacx Neo, I use the skewer that comes with the trainer, it's long enough and make of steel.

I had the same issue with my homemade skewer. I added washers on both sides because I didn't want to scratch the paint, lol!

Every bike I've had up until the V20 has been a bit of a beater, so I didn't even think about it. Now I have circular scratches around the QR . Oh well. Now I'll be able to pick mine out amongst all the other V20s at the cafe.

For anyone needing to remove their disc brake caliper to mount to the trainer, I suggest you remove the mounting braket from the frame instead of the brake caliper from the braket. The braket will always go back on the frame at the same centerline position unlike removing the actual caliper, this means you won't have to adjust your brake when you go back out on the road.

That's a great point, which I didn't do 2 years ago. That's why I got annoyed and returned the Directo trainer. :) Suito much better.
