Appraisal on unknown viintage aluminium frame, maybe carbon frame.
this bike is been sold in Brazil by US$300 as a full carbon made.
There is no brand or badge on it. The stikers were put by the seller to combine with the Specialized tires. I didn't warn him Hardrock isn't a speed bike because I want to buy it.
despite the seller said is entire carbon I suspect the frame is aluminium.
The seat lug remind me Cadex Cannondale. But there is no head lugs, seems it is a monocoque.
Don't know if is there an aluminium monocoque.
So if you guys could help me identify this frame I appreciate any input.
Being carbon or aluminium what would be a fair price for this bike?
Thank you in advance.
