The blue groove is a unsung hero in Kenda's lineup. I haven't seen it on many bikes, which is odd considering the good performance it provides. I've ridden it in bike parks, where it provides ample grip and no squirming or loss of traction. I've also employed it on trail rides, where it dug into loose soil and never slipped on off-camber roots. With that being said, I've also ridden it on hardpack, where it provided good traction whilst being leaned into berms. However, the bulky tread pattern is noticabely slow on hardpack terrain. This tire also excels in mostly dry or slightly wet conditions, as it doesn't shed mud as well as some other loosely spaced tires. Another point is that, like most bulky tires, the blue groove absorbs bumps well, making it a good candidate for hardtails.
Overall, this tire performs the best on varying singletrack with a good mix of ups and downs.
