Why 27.5 wheels

For shorter riders, there are still not quite as many options in the 29 inch market which may limit their choice somewhat. Skip to content. April 2, April 2, Peter Ballin. Table Of Contents. When did When Were the First Major Victories on Are What Are Will 29 Inch Wheels Spell the End for What Wheel Size is Best for Me? Niner started out with a commitment to 29 wheels and still aims to push the wheel size to new boundaries. The RIP 9 RDO 29 is a fantastic example of the enjoyment of riding that the 29 mountain bike can bring to so many people.

Because of the larger diameter of the wheel, the 29er creates a larger contact patch with the ground and also rolls quite faster when up to speed. Even though it accelerates slower than a This trait is also beneficial to tackling technical terrain for the obvious reasons of the greater contact patch with the ground.

Accumulated, all of these benefits turn out to make one heckuva fast mountain bike. After reviewing the differences, you may have already created a bias to which size you might choose over the other. However, here are the general recommendations for who should choose what wheel size. Arguably the most important benefit of It is affected not just by overall static weight but also where the weight is distributed throughout the wheel.

The farther the weight is from the center of the hub, the slower the acceleration. So a similarly constructed gram inch wheel is slower to accelerate than a gram inch wheel—because the larger diameter rim and longer spokes place weight farther from the hub.

The key to snappy acceleration is minimizing the weight of the outermost components rim, nipples, spokes, tire, tube. As you can see, a A larger tire contact patch, increased stiffness, and optimized frame geometry improve traction, braking and handling. The larger the diameter of a wheel, the greater the contact patch of the tire.

A larger contact patch results in better traction, which leads to improved acceleration, deceleration and cornering. Lateral side-to-side frame stiffness can be affected by wheel size.

To accommodate larger wheels, frame dimensions must be elongated. Therefore, a size medium inch wheel frame has more lateral flex bottom bracket and headtube than a size medium Additional flex compromises handling under heavy pedaling or sharp cornering. The larger the wheel, the more difficult it is to optimize geometry, especially on smaller frames. As the frame size decreases, headtube heights become higher in relation to saddle height.
