basically no rounding just the edge is broken
I’ll take a pic!
The pegs are tall by about 5.5mm if that is the case. When you put on those pulleys, you shouldn’t torque the wheel on to tight or the metal will dig into the wheel and it will cause a stress riser. They need to have a fillet on the corner. The stress riser can cause a crack and then that crack will propagate through the wheel. I haven’t seen any pulley designed where they let a sharp corner bottom out into a wheel. That is so dangerous.

I don’t think they bottom out like you are saying. They are installed with a custom washer that comes with the wheel.
Been running mine on TB110’s for over 150 miles already without seeing any signs of wear

I think the inner ring sits against the plastic core
Any dimension specs on the washer?

If you have time, that would be amazing.
So there is the bearing seat and then the washer. Confused about 4.8mm and 8mm ID… You mean 4.8mm is the ID and 8mm is the OD? Confused.

Hey Guys, we have a delay. It is a national Chinese Holiday, “Mid-Autumn Holiday”, which means no one is working for the next 8 days.
I didn’t account for that in the timeline and the tooling is taking a bit longer. I thought by this time, we’d be close to finishing and I’d be doing testing of the production molds.
I had to make changes to the pulley diameter because the Metroboard pulley interfered with the pulley core and add more ribs for more mechanical lock to the wheel (it is on the core side and so it shouldn’t affect performance because that is not the flexy bit of the wheel. So caught in a position where they are still working on the tooling, but now it is the holiday and they are stopping. This means it is another 8 day delay. I’ll be sending an email to all the early pre-sales people.
I also added more ribs for a mechanical lock for added confidence that the Polyurethane won’t delaminate. Though, there is a chemical adhesion and some very strong mechanical locks. Really over designing it, but better safe than sorry.
Please let me know if you have any questions.

Ugh. Yeah, I am bummed about this but do it right the first time. If something happens, I’ll refund everyone. I’m not touching any of this money. Fortunately, I have some successful businesses under my belt that I can afford to do this, but I’m not into burning other people’s cash.
