TC radial front, Romy rear on my trail bike. Really really liking the combo. Good rolling speed relative to the dual diagonal TCs I had on there previously, doesn’t feel like it gives up much cornering grip at all (guessing it’s the radial grip making up for the tread pattern change on the rear,) and I’ll be damned if it doesn’t mute the buzz nicely and suction cup up techy climbs. I’m sold on the combo for anything less than full on DH, that said it’s been quite ideal conditions in the PNW lately so I don’t have any options...
