Im 5'9" and I have rigid 29 and 27.5. I don't think the industry is going to go bigger than 29". Already geo has to be a bit funky to deal with 29er requirements. Too many trade-offs to go bigger. I think the bigger change is going to be settling on wheel width (boost vs super boost, etc). 27.5 is much more maneuverable. Usingthe system based on inches, the difference in diameter between 700C/28” and 650B/27.5” is just 0.5”, which is equivalent to 12.7 mm. In reality, the difference between the 650 x 47B and 700 x Ifyou look at a Geo chart for 29 VS 27.5 you'll see significantly larger bb drop on the 29 and similar bb heights. it was the same arguments for 26 vs 27.5, but I bet you won't buy a 26 bike Formore detail checkout our other articles "26 or 29 You Choose" and "An introduction to 650b". A comparison table of different MTB wheel sizes. Of interest in this table is the N/A under 29" for Gravity. This is quite simply because the 29er hasn't really been used in this area yet. Also the only "POOR" is under 27.5" for Availability - this Ifyou kept head angle and reach measurements the same, with the same stem and handlebar, and only played with fork rake, then 26"/39mm rake=27.5/42mm rake. Yes, geometry principles are the same between 26" and 27.5" bikes, and 29" bikes for that matter. Shorter chainstays being "poppier", along with all the other variables. 26to 27.5 will be negligible difference. The rest of the bike may make a Big difference. But as far as the wheel size, very little difference between the 26 and the 27.5. The 29 will make a big difference. Whether you like it or not it’s probably up to the geometry of the bike that you’re trying, as well as your riding style. People 26vs. 29 Mountain Bike.

To this end, the 29er is more effective in mountaineering than the 26Inch Vs 29 Inch Bike. The main difference between a 26-inch and vs 29-inch bike is that a 29-inch bike has a bigger tire volume than a 26-inch bike. Here’s a closer look at the pros and cons of each: 26 Inch Pros. More maneuverable in tight spaces; Lighter weight; Usually more affordable; 26 Inch Cons. Not as efficient on longer rides bbzbH.
