Foes Alpine Plus

The Foes Alpine Plus. Run 27.5″ x 3.0″ or 29″ x 2.35″ wheels!

The smaller but nimbler little sibling to the Mutz fat bike. The Foes Alpine+ brings a new tire size that is meant to bridge the gap between standard mountain bike tires and Foes Fat Bikes. Naturally we had to start with a clean slate, the head angle, BB height, and chain stay length had to be perfect with the new BOOST specs. The 2.3:1 leverage ratio gives you a nice rising rate 5″or 5.5″ travel position. The Alpine+ is the perfect bike to take you on trail that other bikes would have problems and give the confidence and control. Can also use 29″ x 2.35″ wheels for XC rides!
