Thesame frame features that are present on the Session 27.5 are in place on the Session 29, and, in fact, the two bikes share the same carbon front triangle. Trek Session 29 Details. • Intended6 In theory, a smaller wheel is stronger than a bigger wheel if hub and rim section are the same. This is largely due to the length of the spoke and it's contributions to the stiffness/flex vs spoke braking force. Whether the difference between a 27.5 wheel and a 29 wheel is in of itself enough to mean a real world differe, I don't think so.
The29” wheels are much better at this. Smaller wheels like 27.5” wheels tend not to have as good an ability to roll over things. Tire Sizes. When it comes to 27.5” bikes and 29” bikes, you see different tire sizes. On the larger 29” wheels, you typically see 2.0” – 2.3” tires. On 27.5” bikes, you are looking at 2.2” – 2.6”.
26 vs 27,5" (650B) vs 29" - why? I've been riding my bike for quite a while. I've ridden a 26" Scott MTB, switched to dirt jump bikes (both 26", 24" and 26" front/24" back), then switched once more to a BMX (20") and recently got back to the old Scott 26er for some light XC, so I'm pretty used to every wheel size I thought possible.26 is like Latin. Some people still use it but it’s more or less dead. General rule of thumb: 27.5= more agile, better for tight twisty trails 29= more speed and better roll over, better for chunky trails. Frame design also comes into play as well so it’s not all about the tires. 10.

Thehandlebar is only raised by 12.5 mm going from 26" to 27.5", and the difference in "angle of attack" between wheel and ground is extremly small. That said, I am riding my 27.5 more than the 29er. It has more suspension. And it's actually a Niner WFO converted to 27.5. So the very best of both worlds! Santa Cruz Nomad V.4
