    The Good: Price, Quality frame, weight

    The Bad: Nothing besides the stock wheels.

    Overall Review:

    The 2012 Subrosa Arum is a really sick bike. I've had mine for around 8 months now. It's super solid and can take a lot of abuse. The only bad part about it is the stock Rant wheels. The axles bend easily and overall, they're just cheap. I recently replaced those with some better wheels though.

    This bike was built to be ridden and I will continue to do so for quite some time.
