FiftyOne Assassin Frameset
Best versatile gravel frame for riders seeking premium custom engineering.
This is the ultimate chameleon for riders who refuse to choose between a dedicated racer and a rugged bikepacking rig. By swapping geometry settings on the fly, you get two distinct bikes in one, though you’ll have to accept the slight mechanical complexity that comes with such high-level versatility.
