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”.
Schwalbeprovides the rubber for both bikes with Nobby Nics in either 27.5 x 2.6″ or 29 x 2.35″ – and the 29ers get the new Addix compound. Entity components make up much of the cockpit with their own 780mm wide bar, 45mm stem (both 31.8mm clamp), and the Entity Assault Saddle. The only bummer spec out of the box was the TranzX seatpost
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. Notethe difference in centrifugal force that is trying yo keep the wheel straight. The force is much much stronger on a 29er and that what takes away from the nimble-ness. Also your tire Math makes no sense. You’re trying to apply Thewheel size debate really kicked off when 29 inch wheels were brought to the masses around five years ago. Another neat feature is that a 27.5+ tyre has almost the same diameter as a 29
Thedifference between 27.5 and 29 wheel sizes depends on individual preferences, cycling style, and terrain conditions. Both 27.5-inch and 29-inch wheels
