Accelerometer mount for bicycle

This is a mounting bracket for attaching a sparkfun accelerometer (part number SEN00252) to a bicycle.

Why bother mounting an accelerometer to a bike, you ask? This accelerometer mount is part of a larger project. The idea is to map out the roughness of various bike paths in the city I live in. What I want to do is rapidly sample the acceleration generated on the bike frame by the bumps in the bike paths over a few seconds. I'll then write the peak acceleration to the memory card and ta
