I was replacing brake pads all day to meet a rush job. By evening, my wrist was throbbing and I couldn't grip a wrench. The clinic said it's tendonitis from doing the same motion over and over. Now I'm stuck at home missing work and pay. Please, take breaks and stretch your hands often.
I saw a buddy crank down on his bolts and strip the threads. Now I always use a torque wrench, even if it feels slow.
Back in my first shop job, I'd spend all afternoon tweaking spokes until the rim ran straight. Now with digital gauges, it's faster but feels less connected to the bike. Do you miss the old way of learning by feel, or is the new tech just better?
