22/34 on an MTB wheel is 4.5mph at a cadence of 90rpm. Yikes!


I regularly see 3mph on our MTB tandem as we climb. Still faster than
walking though.

Not everybody has legs like Jobst.


Indeed.

In addition, standing and honking at a low cadence may be fine on the
road, but does not work as well as spinning in low traction situations.

The silliness is a rider much weaker than a UCI professional using the
same 53/39-11/23 gearing.

Absolutely. That's why I run 50-39/12-13-14-15-17-19-21.
