Thanks for the reply, I should have purchased my frame from Hongfu given your experience.  I'm still emailing xmiplay weekly with no response.

The flange nut on the rear bottom linkage on my ip-036 full suspension frame backed off at some point.  Does anyone know what size/pitch/type the nut is or where I could purchase a replacement?  I've made a few attempts at contacting Peter at XMIPLAY over the last couple months but have not received an answer.

Thanks
