A couple of weeks ago, I was halfway into a planned 100-mile ride when the fixing bolt on my American Classic seatpost came loose (they have a tendency to do that after many miles without a problem). In the interest of lighter weight, I had brought a somewhat minimal multitool rather than my usual Park kitchen sink model. Well, the correct Allen key was too short to reach the saddle bolt until I removed the bolt that controls tilt. That allowed me to tighten down the clamp, but it meant my saddle was too nose up for the rest of the ride. I survived but next time I’m bringing the kitchen sink (or maybe a single Allen key that fits that saddle clamp and is the right length).
