I suppose, just worked it out, a Because complete build using all the same parts as the Echo (With a frame and hub swap) it comes to £1162.81.
Thats with a £50 cheaper frame although the hub is £11 more expensive.
Selling the F+R Echo brakes to use my V2's would probably get me close to full retail for them (minus 10-15 obviously) but it still doesnt add up.
Starting to look like a rather offputting, pain in the arse.
