Razorblade 29 IV SL Sram XX SL Eagle Transmission is a carbon cross-country mountain bike (2024), from Simplon, part of the Razorblade family. This bike is aimed at a wide range of riders thanks to its fit flexibility, leaning toward a balanced riding position, while being best for smoother trails and efficient rolling. The main strengths in the metrics are good fit flexibility for dialing in rider position, strong speed potential on smoother terrain, and all-round climbing capability rather than a narrow specialty. That said, what it gives up slightly is a value score that depends more on priorities than pure price efficiency.
