Thisrather odd way of describing mountain bike wheel sizes continued when Gary Fisher came out with the “twenty niner”. Again, the wheel size number stated (“29 inches”) referred to an approximation of the diameter of the outside of the tyre, this time fitted with 2.25in tyres (as that was the average tyre width at the time). So 24.5in rim +
Goingwith 29 wheels and 2.5 tires will reduce the effort it takes to pedal on the average. While 27.5+ has the same effective diameter as the 29, the tires are heavier, and you have to run them at lower psi to avoid major bounciness, which gives them more rolling resistance than 29 tires at higher psi.

Thelarge 29er wheels mean higher speeds, improved traction, and easy-rolling over roots, ruts, stumps, and rocks. This bike is quite stable, and it offers travel between 100 and 120mm. 26 vs. 27.5 vs. 29 diameter. As the name suggests, the diameter of the 26inch bike is smaller than the 27.5 and the 29 bikes. 26 vs. 27. 5 vs. 29 for

Thisis true, but only as a function of the difference in wheel weight. A bigger wheel is heavier by 29/27.5=5% (probably about 0.5% of bike plus rider system). If this heavier wheel was spinning at the same speed as a smaller wheel, there would be more angular momentum, but larger mountain bike wheels spin slower.
Aswith most bike wheel naming conventions, the term ’26 inch’ does not refer to the diameter of the wheel itself, but rather the approximate outside diameter of the tire that fits this wheel size. The actual ISO diameter of a traditional 26″ wheel is 559 millimeters. 27.5″ / 650b Wheels (ISO 584 mm) One thing that makes bicycle wheel
Thewheel diameter is the height of the rim barrel of your wheel from the tire bead seat at the top to the tire bead seat at the bottom. This measurement is in inches and can be found on tire sizes to ensure a proper fit as well as on the wheel itself. Understanding wheel sizes can help you with purchasing new wheels or simply keeping
