Sure is jur.

I took it out again yesterday this time reducing the pressure in the BAs down to 40PSI. Whilst it made for an even smoother ride I think this is too low as the rolling resistance seemed to increase somewhat.

I notice they are rated for 30-70PSI. I have inflated them back up to 50PSI. Looks like the sweet spot is somewhere between 45-50PSI.
