I liked it better 2.35f and 2.2 rear on 21mm inner widths wheels compared to 2.8 front/rear on 35mm inner width wheels. The 27.5+ was sort of plush, but not fast and snappy. I preferred the fast and snappy more lively feel of 29. Also 29ers roll over root better. The 27.5+ will absorb, but not roll over as well.

Otherwise a 26 x 2.4 would not be able to fit into many standard 26" forks, and a 27.5 x 2.1 tire often could. But the opposite is true; the 26 x 2.4 still has a decent amount of room in a standard 26" fork and a 27.5 x 2.1 cannot fit into many 26" forks. Because a 27.5 x 2.1 is 0.7 inches taller on average than 26 x 2.4.

This new category of tires can go by a variety of names- 27.5+, 650+, 6Fattie, or even just “Plus tires”. In all of these cases, the wheel being used is a 27.5” or 650b rim with a 2.8-3.0” tire. Up until now, a typical mountain bike tire has varied in width from 1.9” to about 2.3”. In contrast, larger 29-inch wheels provide better stability, especially on smoother, open terrain. Acceleration and Momentum: 27.5-inch wheels accelerate faster due to their reduced weight, while 29-inch wheels maintain momentum better, resulting in a smoother ride over obstacles and improved endurance. This is because the two remaining wheel sizes, 29″ and 27.5″, give you three possible concepts to choose from. The keyword here is mullet, where a large 29er up front is combined with a smaller 27.5″ wheel on the rear. The concept of combining two different wheel sizes on the same frame isn’t new, already appearing on bikes in the 26 . 192 495 496 257 64 246 205 473
