Been riding rollers for many years but recently upgraded to Inside Ride’s smart resistance rollers and have noticed the front drum actually shooting sparks while riding. I’m guessing it’s building up static electricity and randomly shooting a zap to the metal frame. Any ideas if this is normal, how …

[image] Static electricity zaps with rollers Equipment Hey all, I run Kreitler rollers with 2.25 drums, and ride in a basement that has a humidity of around 40-50%. The static electricity zaps are seriously out of hand. Talking 4-5 times per ride minimum. Last month, I g…

Most likely your rollers are rubbing the carpet to generate the static electricity. Resolve that and you’ll likely be fine

not on carpet. Its hardwood with some of those foam floor tiles on top to protect it.

Still it could be touching the foam, especially with all your weight concentrated to the few touch points between mat and roller frame. You can ground your frame to nearby pipes or try putting the frame directly on the wood

AFAIK, the motion & contact between the rubber tire and aluminum roller drum are the real key here. The rollers do NOT have to touch carpet, foam or anything on the floor in order for static electricity to build up.

This is what I was thinking too. Seems like the solution would be figuring out some way to ground the roller drum. How to ground a spinning drum though…

Carbon brush assemblies mounted with springs to maintain contact would do the job. Then you just provide a path to ground.

I am searching to see if I can find a direct option but I picture one of those electronic wire grounding straps used when working on PC’s & PCB. Connected to ground as normal (or even just the roller frame?), then the “open” end uses some light brass wire riding lightly against the front drum. Jus…

Could probably use some copper tape wrapped around the last inch of the roller to act as a wear surface. Copper tape

Like what’s inside a power tool?
