I had a look for those Larsen DHs, and they're very hard to find. Even the big on-line stores didn't have any when I was looking. It almost seemed to me that they are made and reserved for racers only...The combo with the most top level enduro wins (multiple mega, Mt Hell, Super Enduro, French Enduro Series, Trans Provence, CWX, Enduro Nations) is 2.4 Ardent Front and 2.35 Larsen TT DH rear. Both run tubeless. As run by Jerome, Remy and a couple of other top riders with "other" tire sponsors. This doesn't mean its for you and there are more and more choices every season.
