By the time I put on the pedals, the seat bag with tools in it, the rear light, a bell, and water bottle cages, I'm sure that the weight of each bike each bike has increased by two or three pounds. I don't bother to weigh the bikes with all the gear, but I assume I'm pedaling bikes that range from around 22 to 24 lbs, and that's without water in the bottles. Are people really riding bikes that are weighing in at 16 and 17 pounds? How do they do it?
i think the pendulum has shifted a bit away from super light since most everyone seems to know that aero is really more relevant for most serious road riders, plus disc brakes, plus more cogs, plus bits and pieces of electronics. For the latest 12 speed DA, there isn’t a weight penalty for di2 (comparing to most comparable previous groups) but I’m guessing there is with SRAM’s approach, even at the top end?
i have a 14lb s-works aethos, 12 speed da/di2, disc brakes of course, and the two big compromises it brings are aerodynamics (relatively shallow wheel profiles, round tubes) and cost. It’s really the only bike i ride, and I ride it a lot, so the latter isn’t too much of a concern. I do sometimes wonder how much faster an extra pound of wheels and frame in the interest of aero would make me, and now much would the ride quality suffer from the bigger profiles in various locations.
