After my first ride on my brand new Xtrainer, I noticed oil spray on the frame. I looked closer and saw oil leaking from behind the plastic cover. I pulled the cover off and two of the ears are broken clean off. I can only assume the bolts were torqued a bit too much during assembly and broke the cover.

My question is this; what goes on behind that cover? What function occurs back there and why is easy access required, hence the easily removed cover?
