Hey everybody,
I picked up a used 2007 GF Piranha last winter to do some winter riding. The components are not the greatest -- I think it's all stock.

I was pleasantly surprised at how comfortable the frame geometry is and actually enjoyed riding this bike.

I don't know where this frame sits in the GF hierarchy so my question for the more knowledgeable folks on here is whether you think this Piranha frame is worth upgrading with higher end components like a complete Shimano XT groupset and new forks and such.

Thanks for any feadback!!
