RollingMomentum 27.5-inch wheels provide adequate travelling momentum but are less adept at traversing obstacles compared to their 29-inch counterparts. Anotherthing about 27.5" being very close to 26", is that they are easy to get moving from a standstill. That's the biggest knock against 29" IMO, as well as tough in tight switchbacks As far as 29" gearing, I converted mine to "ghetto 2X10" by removing big ring and replacing with bash, and swapping stock middle ring with 30T. Mostimportantly, a 24-inch bike for adults refers to the wheel size, not the frame size. For kids, 24-inch bikes are typically suitable for those between 4’1″ and 4’9″ or 7 to 11 years old. For adults, frame size is the key determinant of fit, and wheel size is an important factor influencing ride characteristics. HiJohn. The wheel size referred to as 29″ or as a ’29er’ on modern mountain bikes is in fact an ISO 622 wheel. The name is due to the outside diameter of a mountain bike tire mounted on that rim being approximately 29 inches. This is the same reason an ISO 559mm rim is called 26″, even though 559mm is nowhere close to 26 inches. 275 and 29 Plus (Mid-Fat): Improved Traction and Stability. A “plus” or mid-fat bike has tires that are wider than traditional ones (2 to 2.5 inches) but narrower than fat bike tires (4 to 5 inches). Designs that fall into this category utilize both 27.5-inch and 29-inch wheels, although the former is the far more popular option at the moment. Thedifference is that the Giant Stance 29 2 uses 29-inch tires, and the larger tires mean it rides relatively better. The Giant Stance 29 2 has a higher standover height and a larger Stack/Reach ratio. This gives you a relatively higher riding position and a more comfortable ride. 2022 Giant Stance VS 2023 Marin Rift Zone 26″ 26inch – Pump track, dirt jump riding, kids’ MTBs; 27.5-inch – Experienced downhill riders and smaller riders (under 5’9″) 29-inch – Enduro, cross-country, trail riding, beginners, and taller riders 6’+ How 26vs. 27.5 vs. 29 bikes – How do they differ? 26” Mountain Bikes; 27.5” or 650B Mountain Bike; 29er Mountain Bike. 26 vs. 27.5 vs. 29 diameter; 26 vs. 27.5 vs. 29 for short riders; 26 vs. 27. 5 vs. 29 for cross country; 26 vs. 27.5 vs. 29 Enduro; 5 vs. 29 Single-Track; 26 vs. 29 Hardtail and Full Suspension; Compare See more Ilike 27.5, but the trend is definitely towards 29. I don't find them unstable at speed at all, especially if my body positioning is correct. And I like the improved cornering and agility. Most of the trails I ride are narrow and have lots of berm free corners, so the handling of a 27.5 bike works really well. nfhA5.
