Building on the success of the previous
The Direto X now supports up to 2100 watts, that’s up from 1,400 watts the previous models support. The integrated OTS power meter is now also more accurate and can measure accurate power within +/-1.5%. That’s half a percent better than previous models. It can simulate up to 18% gradients, enough to crush your legs up the steepest climbs on Zwift. And it’s equipped with a 9.25 lbs flywheel.

Similar to other trainers from Elite, The Direto X comes unassembled. You need to attach all three legs and install a cassette. Attaching the legs isn’t difficult to do and all the required tools are included. You will find the trainer, power cord, bag with end caps, and manuals. A quick-release skewer is included and a front-wheel riser block as well.
IN THE BOX
- Power cord
- End caps (130 -135 quick release, 142-148mm adapters).
- Front-wheel riser block.
The Direto X doesn’t come with a cassette. So you need to purchase a cassette that is compatible with your bike and install it.
You can purchase an 11-speed Shimano 105 cassette for about $45 but if you are still on a 10-speed cassette then you can save a few dollars and get a 10-speed Shimano 105 cassette for about $50. If you need a cassette plier, the Feedback Sports cassette plier and Cassette Wrench are one of my favorite and easy to use. But you can find a cheaper chain whip, a lock ring tool, and any adjustable wrench should work.
Once assembled, pair the Direto X to the new
Calibration needs to be done to set the brake strength and accurate power measurement. For best results, ride the trainer for about 10-minutes and perform the calibration. Calibration on direct drive trainers should be done once every couple of weeks, if you switch bikes, or if you move the trainer around. Personally, I ran the calibration once and the trainer has been measuring power accurately since. I was able to run the calibration using TrainerRoad and Zwift but I didn’t test it for accuracy.
The Direto X broadcasts power, speed, and cadence. So, it is simple to use with Apple TV which only allows two simultaneous Bluetooth connections.
If you want to hear how loud or quiet the Direto X is, you can watch the video above. But if you prefer to just skip to the noise demo section, just click here.
The trainer is not loud. Maybe a tiny bit louder than the Flux 2 and not as quiet as the KICKR CORE. I didn’t feel any noticeable vibration either. So if you live in an apartment or on the second floor, I think you might be ok.
And for decibel comparison sake, here is how it compares to the KICKR Core and Flux 2 based on my own measurements.
The Direto X
- The Direto measures power accurately based on my comparisons with two different power meters – Assioma Duo pedals and Power2Max crank-based power meter.
- In ERG mode, it’s quick to respond to changes and measures power accurately regardless of gear selection or flywheel speed.
- You might run into wattage floor issues due to its mechanical limitations depending on your gear selection.
Elite claims the Direto X is accurate within +/-1.5%. The goal is to see if the Direto X comes within that claim.
The first ride was just a regular ride in Zwift in sim mode. I used my Assioma Duo pedals along with my Power2Max powermeter. The data looked really good and overall the Direto X was spot on with my power meter. There is really nothing to point out. Everything just looks beautiful and charts like this make me happy.
I did three sprints to see how it behaves during these sprints and again, it looked really good. Maybe overshot at the beginning of the sprint for a second but now I am just nitpicking.
Switching over to ERG mode, the Direto X worked very well to keep me at my target watts. Here is a longish endurance ride with some tempo. It worked well throughout the 2 hours.
Moving on to another workout, this workout is from
Overall the Direto X was very good. It was within a watt or two from the target and a few watts from my Assioma. It was always measuring a watt or three higher than my Assioma but still within range and consistently higher. The consistent part is what’s important to me. As long as the trainer is doing the same thing and that “thing” is within range and not erratic, I am ok with it.
The highlighted section above is when I switched from 53/17 to a much bigger (53/13) gear and the trainer hit its wattage floor and couldn’t bring me down to 224 watts as you see in the below chart. After about 30 seconds of this, I realized the trainer isn’t going to bring me down so I went back to my 53/17. That’s where the little dip happened in power until it stabilized.
So just keep that in mind. If you are a big gear type rider and notice the Direto’s resistance is pretty high, then go up to
ERG MODE AND POWER DISTRIBUTION
Overall, the Direto worked well in ERG mode. I like to look at power distribution to get a good picture of how a trainer responds in ERG mode. For example, if the power target was 235 watts I look to see how much time I spent +/-10 watts of my target. This is usually where more money gets you better results.
In the table below, using the small ring, this is when trainers usually do their best to keep you within range. Out of the 5min interval, the Direto kept me within +/- 10 watts from my target 76.7% of the time or 3:50. Only 30sec above my target and 40 sec under my target zone. This isn’t as good as higher-end trainers. I usually see numbers in the 70% range when using a bigger gear.
When going to a bigger gear, the Direto X kept me within +/-10 watts of my target 50% of the 7min interval. That’s 3:01min. Over 23% of the time spent above my range and over 26% or 1:36min under my range. This is a little below what I like to see but not the end of the world to me. If you want something smoother, then spending a few hundred dollars more would make a difference.
Onto the next test. This is where I look to see how quick it responds to ERG mode. I ran the Direto X through short 30 seconds to 10 seconds long intervals.
Going from 100 watts to around 380 watts took about 3-seconds.
Going from around 350 watts down to around 100 watts took also 3-seconds.
Overall, the Direto took about 3 seconds to reach the target for each interval. This isn’t bad at all but also personal. Some might think it’s slow and yes, it might be 1 or 2 seconds slower than other trainer but I am also not a big fan of hitting a brick wall when entering an interval.
The Direto X broadcasts cadence as well over Bluetooth FTMS and ANT+ FE-C. It tries to estimate it using a combination of power and flywheel speed. Most smart trainers use a similar method to calculate cadence. Some do it better than others.
Here is the cadence data from my sim ride. Overall it was ok. Some occasional drops which is expected when trying to calculate cadence instead of measuring it with an actual sensor.
Overall, I am not that picky when it comes to cadence and I am generally ok as long as the trainer gives me a number to look at. But if you care about accurate cadence
Elite made tiny tweaks and improvements to the Direto year over year making the Direto X the best Direto. The Direto X simply worked out of the box. It’s quieter, better road feel, worked well in ERG mode and measured power accurately. That hasn’t been the case with all the trainers I received this year. At $899, I think you will be happy with your purchase and I have no problem recommending it to anyone
