Is it a short-travel trail bike or a downhill-oriented cross-country bike? It depends which way you look at it. The SB115 is a further development of the SB100, the rear suspension travel has been increased by 15 millimeters, as the type designation suggests, which makes the model launched today a little more forgiving. Of course, the suspension is still firm. Yeti promises the best efficiency in the "pedaling zone", as the manufacturer calls the weight distribution in which you normally pedal. But if you stand on the pedals and chase the bike over the typical relief of a trail, then there is movement in the rear link, Yeti promises, then the bike swallows what there is to swallow.
Racers like bikes that only have as much of everything as they absolutely need. The SB115 aims to live up to this claim in terms of suspension travel. The trail faction may be tempted by the prospect of being able to tackle one more climb thanks to the efficient suspension and thus enjoy another descent.
