GRAM

Enduro
GRAM is a carbon electric enduro mountain bike (2023), from Thok, in the Gram series. Rider-wise, it fits riders who want a more active, performance-leaning off-road feel, leaning toward a sporty, active riding position, and is aimed at more technical trails and rougher terrain. Standout strengths from the metrics include capable suspension support for rougher terrain and all-round climbing capability rather than a narrow specialty. The trade-off to keep in mind is a firmer ride feel than comfort-first options and less emphasis on outright speed than speed-focused builds.
