The smaller construction gives the bike more rigidity and makes it faster and more agile than a 29er wheel. The maneuvering especially on bumpy trails is easier and the wheels are usually also more robust. Because of these characteristics, 27.5-inch wheels are used on most trail or enduro bikes. Especially for full suspension bikes 650b wheels offer clear advantages. The frame geometry of a 650b Fully, in particular the shorter chain stay length in conjunction with 27.5 "wheels offers the best kinematics.
