What are these removable tabs on my rear dropouts?
I posted this over on r/mountainbikes and got no help (deleted post.)
The bike is a 2026 Ascend Zion 29" Large frame from Bass Pro Shops.
According to the spec sheet on BPS's website...
The bike has a 10mm x 141mm QR hub.
But, the front listing appears to be wrong as it lists a 9mm x 110mm QR, and I can't find any parts for that size. I can see alot of 9mm x 100mm options. Everything i'm seeing says 9x110 doesn't exist?
I like the bike, and I want to do some upgrades, but because it's a 'Store house brand' bike, no one has info on it. and, ALL the info I've gotten from Google searches has been wrong. especially the AI overview.
