When I bought the peanut butter wrench to remove my Campy cranks, it took me about 5 minutes to open my wallet and pull out the $30. But at least it says Campy on it and can do multiple tasks. The thought of paying $70 for a gauge that only measures seat tubes is beyond my comprehension. If I had that kind of cash to waste, I would have already clicked BIN on the 7-11 Eddy Merckx.
