The part number is jbt-78. They look quite like some normal wheel end caps, but I've been through my spares, and the diameters/threads are different.
I picked up one of these trainers, but it only has the thru axle caps (jbt-79). At the time, I kindof thought the widely available qr skewer kits might help me out, but they are only for old, friction trainers really. I *do* have it going - at an offset! - so only have 5 gears or so, and it's not very sturdy..
Thought I'd post this, as lots of outlets are selling these vaguely identified skewer kits for $30, and they're most definitely NOT what you want.
Gotta say, while it's a big, sturdy piece of kit, the electronic and software side of it is rubbish, and reading around the web , the story seems the same for all jetblack trainers. Bugs that never get fixed. Apps never worked, and sensors don't operate properly with 3rd party bike computers.
My 2cents....
Maybe I should have bought a Kickr, but honestly there are enough computers in my life, and just wanted a quiet direct drive trainer... Working properly
