Omnium Zero-Drive Portable Trainer

Trainers that lock in the rear wheel are heavy, and full-length rollers take up a lot of space in the car. And as dedicated cyclists, it's all about getting in the workout as conveniently as possible; and Feedback Sports has a solution with the Omnium Zero-Drive Portable Trainer. The folding design is a scant 13.3 pounds — compared to the typical 40+ lbs of rear-wheel resistance trainers — and fits most wheelbases, and accommodates 16 through 29-inch wheel sizes. Feedback Sports designs the Omnium to offer no resistance other than the rollers' inertia and allow the rear wheel to move about a bit more naturally and mimic normal riding. The trainer totes easily to races for a quick warmup or for hitting key, high cadence drills that are more skill-based.

The trainer comes with a durable, water-resistant carry bag, and thru-axle adapters for boost and non-boost bikes, and 9mm quick release. Cannondale Lefty, 20 x 100mm, and folding bike adapters are available separately.

I love this trainer!

I've put it through the wringer

I travel a lot in a van. This little trainer is light, takes very little space, and sets up quickly. I’ve used it probably 100s of hours, and it’s still going strong. I used a PM on my bike to connect to Zwift. The motion in the back wheel helps prevent sores and promotes comfort. It’s a brilliant design.

Not a good trainer for heavier folks

I've used it several times

The description says no resistance but that is simply not the case if you are overweight. Ive tried different bikes with different tire sizes and there is just too much resistance even on the easiest of gears. I will say the feel of the bike moving naturally is spot-on. If you need something to get warmed up on for a brief period, this is a good trainer. Sadly it just didnit work out for me.
