Purchased the ZTTO DR190 54t ratchet hubs.  The spoke holes are double drilled shaped like a key hole.  Anyone know the purpose of that?  ZTTO says it's for better durability but I'm scratching my chin.

Nice wheels and all, but can I ask about the truing stand? Is that an AliExpress model or rather a Western product?

Good luck with your degree!

Thanks, I will definitely double-check.
My rides felt normal otherwise but the brake power has quite some leverage through the fork, right?
Did you "feel" anything while riding?

I'm using the same Zeray ZP-108S pedals and am pretty happy with them. However, one of the pedals came with too much preload, and therefore doesn't spin as freely as the other.

I've opened its plastic cap (see attachment) but can't figure out how to disassemble it further: the screw head inside doesn't seem to take a hex wrench -- the inside of its head looks round (see other attachment). Could you help?

Crap I was going along building up the bike bit by bit. Routed all the cables and then wanted to mount the bottom bracket… and the drive side is not good, the bottom bracket simply doesn’t catch the thread and go in. I emailed Wendy for a solution but I fear it needs to be replaced or atleast rethreaded

Do you think the brake performance is being hindered by the internal cable routing?
I'm thinking about building up a road bike and using an old 6800 Ultegra group I have but I'm a bit nervous about how mechanical will perform with internal routing...the turn at the handlebar into the stem then into the fork must be brutal on the brake cables.
