1. 27.5 inch (650b)


Offering a middle ground between standard 26 in. wheels and 29ers, these bikes apply a “best of both worlds” solution, more easily rolling over terrain than the 26s, but more maneuverable than 29ers. 27.5 inch wheels can be found on both full-suspension and hardtail rigs.

2. Lightweight Design


Ultra light weight design with 265g will provide much better riding experience.


3. Hookless rims will more protected against dings

While hookless construction does create a stronger rim edge, it isn't the entire story of improved tubeless security, but have a bead lock that discourages the tire from unseating if deflated. It also cradles the tire bead for improved seal. Greater force is required to move a tire bead over bead lock than to unseat a tire bead from a rim hook.


27.5er vs 29er


  27.5er 29er
Acceleration Faster More efficient
Traction Good Better
Attack angle Good Better
Weight Lighter Heavier
Maneuverability Better Good
Fit Favors shorter riders Favors taller riders




27.5 in. wheels have faster acceleration while 29ers are more efficient on longer rides


Smaller wheels accelerate faster than larger wheels. This is due mostly to where the weight of the wheel is distributed. Larger wheels place the weight of the spokes, rims, tubes and tires farther from the center of the wheel, resulting in higher rotational mass and slower acceleration. When you cut down on the rotational mass of a rolling object it will roll faster and with more ease.


27.5er : Faster acceleration is often cited as one of the biggest benefits of a 27.5” wheel when compared to a 29” wheel. Wheels that accelerate faster give a bike a snappy, responsive feel that many riders desire.


29er : Wheels that accelerate slower take longer to get up to speed, possibly giving the bike an unresponsive feel. However, once the larger wheels reach top speed, they’re actually more efficient for longer rides than smaller wheels because they require less effort to keep their momentum going.




Because of their greater surface area (aka “contact patch”), 29 in. wheels have better traction (when comparing comparable tires)


27.5 in.: These wheels provide very good traction and are good for most purposes. Other considerations, such as acceleration, weight and fit may ultimately be more important factors in your choice of wheel size.


29 in.: These wheels, with their larger contact patch, may be your best choice if grip on slippery rocks and roots is a top priority.


Attack Angle


29ers roll over objects more easily


Attack angle is the angle formed when the round wheel touches a square object. A shallower angle is better because the wheel can roll more easily over the object.


27.5 in. wheels don’t roll over objects as easily as 29ers, but they are still very capable. Think about where you’ll be riding: if you’ll mostly ride smooth trails, 27. 5 in. wheels will serve you just fine.


29 in. wheels have a slightly shallower attack angle than 27.5 in. wheels, making them better at rolling up and over any logs, roots and rocks that you’ll encounter on the trail. Many riders feel more confident with larger wheels.
