Heyday! C Deore 12
Salsa
Fatbike
Heyday! C Deore 12 is a carbon fatbike mountain bike (2025), by Salsa, part of the Heyday family. Rider-wise, it fits a wide range of riders thanks to its fit flexibility, leaning toward a balanced riding position, with a surface profile that is useful on softer and looser terrain. Its strongest points in the MatchBikes metrics are strong climbing friendliness for sustained uphill riding, good fit flexibility for dialing in rider position, and a balanced ride feel between comfort and directness. The main trade-off is less emphasis on outright speed than speed-focused builds and a value score that depends more on priorities than pure price efficiency.
