no, i'm not talking about what happens when you give an armadillo speed, i'm talking about the tires and how fast you go. i was wondering if any of you have noticed what i've noticed with armadillos. i put those on my new wheelset, and the tires feel really sluggish. my steamroller is geared 49 - 16, the spicer is geared 47 -16 (with armadillos) and with all other things being equal (tire pressure, tire size, etc.) its harder to maintain speed and acceleration than the higher geared bike. have any of you that use these tires noticed this? just curious.
