Blarg, trainer has started making this horrible noise:
Any other H3 units have experience with this noise?
It only happens when it’s slowing down to a stop so it’s not that annoying (relatively speaking). I’ve had this trainer for about 4 months now and have put a bunch of hours on it recently as I’m stuck at home.
I emailed Saris support but given the current conditions, I’m not expecting a speedy reply.
they wanted to do that but i talked them into sending me one 1st. still have not returned the old one. been on lockdown here and have not been able to drop it off at fed ex
Hey, I bought my H3 in March and I’ve had no knocking sounds and certainly nothing like that squeal you have in the video.
However, recently it started to feel like the H3 is “grinding”. You feel it through the pedals and can hear it. I can only describe it as feeling like the ball bearings need greasing or as if theres sand in the bearings. Just in case, I changed my cassette and chain today but I still get the noise.
@joxer72 what was your outcome on the grinding? My H3 has recently started doing this. I’m going to reach out to Saris support, but looking for community feedback.
Hmm…… in the end it just resolved itself. Apart from cleaning my cassette I don’t think I had to do anything. That was a long time ago now though. Since then I had only one other issue whereby I had neglected to put a spacer between the largest cassette cog and the turbo to prevent it rubbing (or something like that). I can’t quite recall.
I’m working with Saris support but they aren’t very responsive. They had me check the top hat spacer, behind the free hub but that looked good for me. I sent them a video with the noise. When spinning at normal cadence, you can’t really hear it with the drive train noise. When spinning the crank slowly by hand, you can hear a spot that’s rubbing.
Ok. I’m trying a few things out this weekend, I’m going to try another bike and also clean and reassemble the cassette. I have 11 speed shimano and have 1 spacer between the largest sprocket and the H3. Its always been a very tight fit to get the retaining ring on after the smallest sprocket, not sure if that means I’ve set it up wrong.
I did some investigation last night and it definitely only happens in harder gears on the rear, irrespective of the front derailleur position or whether I’m in erg mode or not…
As I’m based in the uk, I dont know what after sales support I’ll get. Ill reach out to the retailer if I don’t get anywhere this weekend.
So, I took the bike off the trainer, put the H3 up on a bench and spun the cassette manually with a cassette vise whip wrench. I had removed the end cap, so I could pull the cassette+hub off the axle while the flywheel was spinning, to remove the freewheel ratchet noise. I couldn’t hear anything unusual anymore. Maybe mine was a fluke, but there was a distinctive rubbing before. Reassembled everything and put the bike back on and I’m just hearing drivetrain.
Thanks…… The reason I had the spacer was because the derailleur would be pressed right up to the h3 in the largest rear sprocket. I’ll re-assess the whole setup tomorrow….
No, not really. Probably all I ruled out was a loose flywheel or something similar, since I was spinning the cassette unpowered. In my workout this morning, I still felt some rumbling, kind of like riding over a course road. I don’t actually have noticeable noise – it’s all feel. It’s hard to compare, but it might be better than before, but some kind of rumbling is still there, just not as noticeable.
Hi there…… Given that it only happens in high gears, I had a theory that it might be to do with the chain angle from front ring to rear ring. If the chain is at an angle the friction between individual the links is greater. I took the cassette off and gave it a good clean, same with the chain…a really thorough clean. I then greased each individual chain link with a good quality lube…… so far it seems to have resolved the issue. I have done this before of course, but probably not as thoroughly.
I mostly use ERG mode, so I sit on the middle cog of the cassette, for a straight line to the chainring. Any noise I have is strictly normal drivetrain noise.
My issue is more about a vibrating or grinding sensation as the power goes up. It seems better although I haven’t really changed anything. But, I might just be getting used to it.
