I would say it could be the 2010 DHR, cause if it was just a prototype then it would probably not have any logo's on it, or maybe just have 'prototype' on the downtube... but seeing as it has the DHR lettering on it maybe it is the finalised model.
Agreed, also considering the paint color looks like it had a long time spent on it and the rc4 on it. Most prototypes just have a generic looking coil shock rather than something brand name.
i know that a commencal supreme uses a single pivot design and the DHR uses the dw link.. im just saying the design looks really similar to each other if you put them side by side and ignore their suspension's pivots.
