Through sexual cycling around is one of the main factors of efficiency,increase of wheel diameter can reduce wheel Angle when in contact with obstacles,roll over obstacles,the easier;29"Angle of attack Angle is smaller than 26" six degrees,27.5"smaller than 26" 4 degrees,26,maximum Angle of attack Angle,29 through sex is best,27.5" is very close to the performance of 29".
The greater the wheels on the other hand,the higher the center of the car,29,"center of gravity is lower than carbon 27.5 rim for grade efficiency,27.5" is better than 29" big wheels for climbing ability is significantly increased,26" climbing Angle 20 degrees,27.5"climbing Angle of 25 degrees,29" climbing Angle of 30 degrees.
