Bike fit's nice, but it's not the magic bullet for lower back pain. Sure, adjusting saddle height and reach can help, but what about that rider's conditioning? If you're weak in the core or tight in the hips, no bike fit's gonna fix that. It’s like slapping a fresh coat of paint on a rusted car. Terrain plays a huge role too. Rough trails or long climbs can wreck even the best fit. So really, how much can we rely on bike fit alone? Are we just avoiding the bigger picture of overall rider health and fitness?
