Growler 20 Microshift
Rocky Mountain
Trail
Growler 20 Microshift is an alloy trail mountain bike (2024), by Rocky Mountain, from the Growler lineup. This bike is aimed at a wide range of riders thanks to its fit flexibility, with a setup that gives you a balanced riding position, and is well suited to natural trails and mixed off-road terrain. Its strongest points in the MatchBikes metrics are strong climbing friendliness for sustained uphill riding, strong value-for-money versus many similar bikes, and good fit flexibility for dialing in rider position. Compared with more specialized alternatives, the compromise is a firmer ride feel than comfort-first options and less emphasis on outright speed than speed-focused builds.
