SENTRY
Calibre
Enduro
SENTRY is an alloy enduro mountain bike (2024), from Calibre, part of the Sentry family. It is best suited to riders looking for a balanced off-road setup, with a balanced riding position, with a surface profile that is aimed at more technical trails and rougher terrain. Metric-wise, it stands out for strong climbing friendliness for sustained uphill riding, a balanced ride feel between comfort and directness, and capable suspension support for rougher terrain. That said, the main trade-off is less emphasis on outright speed than speed-focused builds.
