I mounted up the Schwalbes this afternoon and took them out for a quick ride (mainly to adjust the new saddle I put on the bike as well). The comparison to anything else is unfair though because the wheels are new to me Hed Ardenne Plus SLs with crazy 25mm width. These 25mm tires measured out at 28mm wide at a paltry 85 psi, as compared to 23mm GP4000s IIs at around 24.5mm and 23mm Gatorskins at around 23.5. So, no surprise that the ride was ridiculously plush and cornering crazy glue like. I'm aiming for 50 miles on them tomorrow so should put them through a good test.
