These are the summer meats for my otherwise-winter bike. Changing to these is faster than pulling all the studs out. ;)
Noticeably stiffer than my Cake Eaters, and quite a bit smaller. Occasionally pedal strike, but nothing that can't be dealt with, certainly not a deal-breaker. Heaps of traction on loose stuff. Feels more like my 27.5 "plus" bike, but with endless grip and slower. If you like the "tank-traction" feel of a fatbike without the bouncy bloat from really fat tires, these seem like a great compromise.
