What happens if you marry front and rear suspension with bigger 29" wheels? You get an incredibly potent mountain bike that offers great traction, rolls excellently over trail obstacles and is very comfortable on longer rides. The larger wheel size carries momentum better, meaning you expend less effort riding over open terrain, while the increased tyre contact means better grip when climbing. 29ers are also more suitable for taller riders. These days, you'll find every type of full-suspension mountain bike available with 29" wheels.
