We used them last year, and again this, at all four wheels. We learned from last year's prototype that YES, all four would shift simutaniously, but it was a struggle. A giant servo was used via cables to shift them, but the #4-40 threads would pull out of the linkage.

We considered shifting again this year with one continuous cable (spectra cord) and a short throw pnumatic. But decided that the risk of getting one or more wheels caught out of gear was not worth it. I.E., six robots and nine goals on the field may not leave many fast lanes open - so we're locked in first gear.
