In my training the plastic cover has the same scratches ā¦ I think the reason for the scratches is due to the proximity to the upper pulley and the oscillation that it has when applying force.
I have scraped the plastic cover with a cutter to gain space between the upper pulley and avoid rubbing with it

The lower pulley is ribbed and guides the belt. Iām not sure but I think that with a top grooved pulley the H3 would have the sharp sound of Kickr trainers not nice during the whole time of the activity
To silence the sound of friction between the belt and the pulley there is a product used in the automotive industry. When I can go to the auto parts business I will leave the details here

I rode a 2018 Kickr and donāt recall any sharp sound. It was actually quieter than the H3 in general operation, aside from the louder SunRace cassette and some random clicking sound which Wahoo said they fixed but was still present on the unit I borrowed from my LBS.
To the tests and comparisons of the youtubers with the most followers I refer you ā¦ the sound of the wahoo seems very annoying to me in a video, I imagine that shooting with it must be very shrill ā¦ although some units can always come out with this problem and others quiet ā¦ I think that large and toothed pulleys like those of cycleops 1 and 2 are a reason for loud
A good example on this YouTube channel, the Saris H3 was the quietest of all the rollers that passed its tests.
The coupling of the belt and toothed pulleys horizontally in the cycleops are the reason for the loud sounds that this roller emits
That first video is not a very good test, DCR doesnāt even do decibel tests because they can be skewed by so many things. Using whatās likely a free cell phone app is not really proof of anything. In every test Iāve seen the Kickr is quieter, and personally having used both, I can confirm that as well
Honestly, until the people of Sigma (wahoo) update their Kicker, they have no reason to sell a roller without a powermeter for ā¬ 1,200, with a smaller flywheel than the Saris H3 with a much weaker and primitive structure easily cloned by Chinese manufacturers. Low quality and available on Aliexpress and the like ā¦ I had a wahoo element Bolt for a few days trial and it left a lot to be desired

How is the structure weaker? Where are these fake Kickrās for sale you mention? And what is a Potentionmeter
Have you ever looked inside of a Saris trainer? Itās the same guts as a Kickr just in a redundantly large casing, which Iām also convinced only had overheating issues for the H1/2 because everything is enclosed in a hot metal box whereas the Kickr is open and hence better ventilated.
I say nothing that anyone interested can find out
Ok Iāll bite. I went on alibaba and did not find any fake wahoo trainers for sale. I also looked up what a potentionmeter is and donāt see how it relates to a smart trainer.
I suspect he got an auto correct from āpowermeterā, but you are correct that a potentiometer has nothing to do with smart trainers.
The criticism of the kicker design and strength ad superficial at best. Never seen any of these trainers fail structurally.
He is likely referencing the Magene Gravat trainer, which is a Kickr clone. Interesting that it started with the fading inverted T shape, that ended up on the Core.
Overall, I find his criticism of the Kickr odd. And the unwillingness to expand and placing the burden on others is a lazy, and nearly troll-like tactic.

Thanks Chad, and on that note the Kickr and H3 and as far as I know every trainer out there, uses some kind of optical power sensor and not a strain gauge. I know Iām guilty of some excess criticism of the H3, but I give credit where itās due. Itās still the best performing ERG trainer that I have used, and not just because DCR said so but because I have used the Kickr and NEO personally to compare. The Kickr is a close second.
Just by putting Trainer Bike these Wahoo clones appear in stores like Aliexpress, but it is easier to trolling

As far as clones go, anything that sells well gets copied. We wouldnāt say Rolex watches are easy to clone, and LV bags are just as easy to clone as anything else but theyāre more popular. If anything, counterfeits are a bit of a compliment to the original company for making something so successful that people want to rip it off.
Obviously everyone has their own point of view. At Saris they have developed a very good product with their H3. Its large flywheel and a Powertap powermeter, the stiffness of a solid unibody structure where all components are rigged augur well aging and easy maintenance

It does not have a PowerTap power meter it uses the same kind of optical sensor as everyone else, and power accuracy gets progressively worse as flywheel speed increases, unlike the Kickr. Letās not make it something itās not, itās a good trainer, but the Kickr is better overall
This is it seems that the Saris H3 has a power estimator with PowerTAP technology. Regarding the sound that the Saris H3 does when much power is applied in Sprints, strength series and strong earrings, I think it comes from the bearing of the upper pulley. The reason that leads me to believe this is the next. When applying the rear axle of the bicycle, the bushing and the upper pulley describe an oscillating movement of all these zones including the bearing the upper pulley. When there is a lateral force in the inner zone of a bearing is not designed to withstand this work and we have sounds scratching the metal
Whatever power estimator it has is not very good, I donāt care if itās made by PowerTap or anyone else, it just factually is inferior to other units (go see SmartBikeTrainers test and see how power accuracy degrades with flywheel speed). The sound in question has been proven to come from the belt and pulley interface, not the bearing, because when texture is applied to the pulley the noise goes away. Saris themselves have admitted to this issue. No other trainers make this noise and they all mount the bike the same way. Why are you so determined to go against the grain for what is proven to be FACT?
The pulley of my unit is also scraped and the noise I assure you is not caused by the belt and I am not worried about replacing a bearing when the noise is worse
Iāve seen the SmartBikeTrainers test and the differences in the last block
Because your pulley scraping has almost certainly worn back down to a smooth surface, because of that enclosed design of the H3 you claim is superior to the Kickr which creates an oven-style environment where this texturing does not stand a chance especially with the pressure of the belt being pressed into it at all times. This thread will still be here to help you when you come to terms with reality
