It feels like a mantra by now, but let me say it one more time - the Rift Zone is a bike that exceeds its' numbers when it comes to downhill capability and performance. You could definitely jump into a low-stakes enduro race here and there, knowing you won't be terribly under-gunned, and it definitely won't hold you back on the local hot laps. Though the suspension performance biases a bit towards the descent, I wouldn't hesitate to spend a long day pedaling the Marin to access fun and challenging terrain.
