I am using the new Power one 120/70 V front and the 180/55 B rear, my question in that they appear to be larger in diameter than the 120/70 PR-C and the 180/55 PR-D that I ran last year, does any one have the exact specs? Are the cold pressures the same as the old Power Race, 30 front and 22 rear? Any changes on suspension setup that any one has found with the switch? Thanks
