Fluid 2 Trainer with Sensor

CycleOps takes its top-selling trainer in the USA and adds a dual-band ANT+ and Bluetooth sensor so you can reap the benefits of virtual training through various apps with the Fluid 2 Trainer with Sensor. Unfortunately, that gives you one less excuse to stray from that training regime once daylight savings time hits and the weather goes south. Its fluid resistance unit is quiet (64-68 decibels at 20mph) and offers a progressive power curve for an accurate, real-world road feel. With that going for it and the ability to compete against other cyclists on virtual courses online via training apps and its included sensor means you'll actually have fun and get results this winter in the relative comfort of your pain cave.

If you can swing it, we'd always recommend a fluid trainer over a magnetic one. Rather than using a giant magnet to slow down the freewheel, the unit is encased in hydraulic fluid. Unlike a magnetic unit, where the resistance's variability is controlled with a remote, a fluid trainer's resistance reacts to your pedaling force to increase and as such, feels more realistic. CycleOps uses its Power Band technology that makes the level of resistance function with the rollers speed taking your gearing and cadence into the equation. This gives you a range of anywhere from 20 to 725 watts, ideal for most any workout. The Fluid 2's precision-balanced flywheel doubles as a fan so no matter how many watts you produce the resistance is stable and the unit stays cool.

The Fluid 2's two-inch roller means you'll have a smoother ride with less tire wear. It features a wide, stable base adding security on any surface, and asymmetrical leveling feet ensure you'll always be balanced. The rear wheel mounts easily and a simple bolt-action lever tightens the resistance unit around the skewer. You won't have to readjust your bike every time you put it on the trainer. Sprint, jump out of the saddle, and time trial without the worry that you'll pull the rear wheel out of the trainer.

The CycleOps Fluid 2 Trainer will accommodate tires from 26 to 29-inches with rear spacings of 120, 130, and 135mm. An optional thru-axle adapter for 12 x 148 and 12 x 142mm bikes is available separately.

My new morning routine.

  • Familiarity: I've used it several times

I live here in Utah and our air quality takes a turn for the worst in the winter. I'm not really a gym goer. So after some deep research, borrowing of a friend's trainer and lots of convincing testimony, I broke down at purchased my very own. I can't lie. I love it. I love riding my bike(s) when it is nice out, so hopping on the training for a quick ride in the morning is no big deal. I haven't yet connected to Zwift, or other available apps. BUT I EASILY set up and connected the cadence reader to my Garmin Vivo Active. (On you're watch you'll go to set up and "add apps".) Noise was big factor for me, because I fully planned on vegging out and watching movies, and this trainer s about as quiet as it gets. I have noticed my tire wearing down, so I'd recommend a proper training tire if you plan to ride often. My road tires need to be replace so I'll probably just wear them out this season. Set up was easy. It's very stable, feels solid standing and pedaling. And the trainer comes with a plastic cupped stabilizer for the front wheel. Overall, love it. CycleOps makes a really nice product.

Quick update. Riding 1 to 2hrs a week has worn down my road tire quickly, which lead to a slightly noisier and squeakier ride, so I just picked up the Vittoria Zaffiro Pro Home Trainer Tire - 700x23 and wish I had done so sooner. The ride is smoother, and some how cut down dramatically on the noise for a much quieter experience!

You sure that’s the right image for this product? That’s a Cyclops Supermagneto. I think the image should just be a Fluid2 with a cadence sensor.

Hey there,

You are correct, that photo is incorrect, sorry about that! We will get that updated and corrected ASAP. In the meantime, feel free to reach out with any other questions.
