2023 Trek Fuel EX 8 Gen 5
Fuel EX 8 is the ideal trail bike for riders who want a versatile full suspension ripper that makes soul-crushing climbs less painful, but can also huck rowdy trails. It hits the sweet spot of value and performance in our mountain bike lineup by combining high-end parts with a stout but light alloy frame.
