The final word
If the amount of adventure you can get per dollar spent is a priority for you, you won’t do better than Checkpoint ALR 5.

Quality parts, a durable alloy frame that keeps the price in check, and a wealth of features like extra tire clearance and customization options so you can confidently take on bigger, better adventures.
