I’d have to go with the dura-ace 7700 bottom bracket. What a piece of shit. It would mysteriously tighten down on itself to the point where I felt like I was pedaling through sludge at least once every two months. The cups and lockring were made out of soft aluminum so the notches would get torn up by my lockring wrench. The seals were terrible too, the grease would be all gritty after the inevitable 2 month overhaul.
that thing ate jeans like like a monster. I was nervous to even ride in real cycling gear on that saddle because I didnt want a crotch hole in a $100 pair of cycling pants.
someone at polo a few weeks ago had a mini-pump that had a flexible hose like a floor pump. It also had a tab you flip down that you can step on and use it as a floor pump.
I have the Road Morph version, fits right in my bag. The rubber seal around the valve connect is a little snug so you still have to be careful when you disengage it from the valve but it’s still a nice piece of kit.
Worst thing I ever got was Profile Design bar end brake levers, cheap and nasty. One would never sit in the bars properly and would rotate when you squeezed the lever.
