🌙 27.5 Vs 29 Wheel Diameter
Yes 29-inch wheels do tend to offer greater speed compared to 27.5-inch wheels in certain conditions. The larger diameter of 29-inch wheels allows them to roll over obstacles more easily, maintaining momentum on smoother trails. This results in a smoother and faster ride, especially on terrain where the bumps and roots are less pronounced.
Înprezent, bicicletele de munte mainstream au trei dimensiuni: 26 inch, 27.5 inch (cunoscute și sub denumirea de 650b) și 29 inch (cunoscute și sub numele de 29er). Trebuie menționat că aceste specificații se referă la diametrul anvelopei exterioare, nu la diametrul jantei.
Wedon’t suggest choosing the largest or smallest values of a size range. For example, with a range from 1.9” to 2.1”, 2.0” is an optimal option for most riders. The chart is only applicable to Light Bicycle rims with a unique rim-tire interface. If you use rims of other brands, please send a rim profile to the tire maker for
Toclarify, there are three commonly used wheel sizes in the conventional bike market—26”, 27.5”, and 29”—that are based on 559, 584, and 622mm bead seat diameters, respectively. Just as a 700C wheel is the same diameter as a 29” (29er) wheel, 650B shares the exact same rim diameter as 27.5”.
Theadded volume also makes for a larger overall diameter of the wheel. Many tests have been done, and in some cases a 27.5” “plus” tire will roll as fast, or faster than a standard 29
Theactual difference between these two wheel-tire combinations is a whopping 29 mm, though this also depends on the specific rim and tire used. *European Tyre and Rim Technical Organisation Similarly, a tire specified as 50-584 in the ETRTO system is equivalent to 650 x 50B in the French system.
Otherwise650b/27.5 if you prioritize volume, or 29er/700 if you're regularly on tarmac. Are you doing a custom frame? If so, geometry will dictate handling more than tire size. Find out what your builder suggests for overall wheel diameter based on the overall bike size, then decide the volume you want, which will point you to the right rim size.
The27.5 Maxxis rubbers out-hefted the 700c version by a fair margin, but our house-built hoops were a bit lighter than the Zipp setup, and it translated into barely a 70g weight gain between the two setups, with the 27.5 variant clocking in at 17.52lbs overall. That said, any weight that was added went directly to the very edge of the rotating
MTBtire sizes: 26", 27.5", 29" etc Road bike tires also measured in a made up numbers system, just one made up by the French: 650c, 650b, 700c, 700b etc. 27.5" and 650b are the same bead seat diameter. 700c and 29" are the same bead seat diameter. This is why the only system that makes sense to measure rims in is ISO.
A27.5” bike generally feels a lot more ‘chuckable’ (i.e. reacts more quickly to steering) than a 29er. Compared to a 26” bike, a 27.5” bike is much more balanced. You can still change direction really quickly, but you can also flow through fast sections more easily than with 26” wheels. It’s great fun, and the wheel size you
Atfirst the 700C wheel was fitted with a 35C tire. The total diameter of the wheel including outer tire was about 700mm (27.5 inches) , but later the outer tire became thinner and thinner, so now the 700C total diameter of the rim plus outer tire is less than 700mm. Take 23C as an example, it is only 668mm.
