I had an older Tacx smart trainer and decided to upgrade this year. I do lots of GPS rides of routes in the Texas Hill Country and this one is much more realistic than the old one. It's also much quieter, all around just a huge improvement. After using it for 2 months I'm going to upgrade my wife's trainer as well.
This has transformed winter training for me. The direct drive with Zwift compatiblity actually makes working on the trainer an enjoyable experience. The flex in the trainer is nice, Unit feels stable. Was concerned about quality issues described shortly after release, but have ridden about 40 hours without problems. Only thing I would say is that the Tacx software is not the most user friendly and the unit is cumbersome to carry around
It is expensive, but well worth it. Let me first say that I was not a fan of trainers. I have had a few and tried others and found them to be unrealistic in the resistance and not smooth at all. Until I got these, I preferred rollers. Now I like both for different reasons. The Neo is smooth and really quiet. You bike makes more noise than this trainer does. The box and the styrofoam were badly damaged when I got mine, but the heavy unit was intact and is working well. I mounted a 10-spd Shimano cassette (with 11 teeth) using the provided lock-nut and a Shimano cassette tool. It pairs with my Garmin and provides speed, cadence, and power data.
Very quite trainer. Using with Zwift. I like the simulated hills, and rough roads. The first time I went over coblestones, I was not paying attention and was shocked at how realistic it was. I went from basic rollers where it was tough to keep from going mad from boredom after 10min, to easily riding for an hour fully stimulated. Only issue is overheating, so I need to invest in a larger fan. Pretty expensive, but I figure it will keep me in shape through winter so hopefully it pays for itself in the long run based on my life expectancy .
