Budget portable trainers for time trial warmups


I’m looking to join time trial races for the upcoming season. Anyone have recommendations on portable budget trainers specifically for pre-race warmup? I know the omnium portable trainer has been mentioned quite a few times on the podcasts, but I think it’s too expensive especially if I’m only using it for pre-race warmup 2-3 times a year.

I see some of these trainers on Amazon for $100. Wondering if anyone has experience using them for this purpose (model, price, how many years, etc.).

Thank you.

Find a used KK road machine.


Many I know use the Feedback Sports. Some are sponsored, so that helps.
Others use the KK Road Machine.
I think these are the two best options.
Rather than spend $100 at Amazon for lower quality, go for the KK used.
They are solid and last well.
I got mine on Craigslist for $100.
Took a bit of persistent looking, but it can be done.
