We appreciate a challenge. 5.10 is a rating in the Yosemite Decimal System which is used in grading the difficulty of rock climbing routes. Initially, it was intended to be a scale from 5.0 to 5.9, with the next logical step being 6.0. Numerically, 5.10 is equal to 5.1, but in YDS it represents an unanticipated amount of difficulty. It is the point where things start to get really interesting and non-obvious.

Early rock climbers could never have imagined people climbing something as difficult as a 5.10 at the time YDS was conceived. As technology improved (rubber compounds, safety equipment, new techniques, etc.), more difficult challenges had to be accommodated by changing the existing patterns.

Changing technology and ever present challenges are an integral part of any design effort. We think we can help you rise to the occasion.
