Happy Holidays!
Can you post frame geometry and more details? Is the chainline 52mm or 55mm? The website doesnt work very well on my phone I cant see the details but it says UDH rear derailleur hanger?
I think it is 90mm rear travel with 190x45mm shock.
You can consult them and they will give you a detailed reply.vivian@tantancycling.comsales01@tantancycling.comWhatsApp:+86 13690938214Attached is the geometric diagram for your reference. Support UDH.
