This (to me) is especially true when mountain biking. The trails I like most have a LOT of short but very punchy climbs. The whole experience is one of doing intervals, blasting the downhills but gathering strength for the next climb. My road rides these days are much more chill, without any of the fast accelerations in the pack from my youth. Odd then that my heaviest bike is the one I ride on the trails. Alas & so it goes.:)

What makes a bike joyous is not 1 mph, 15 mph, or 23 mph, but the dynamic changes between those velocities. On Sunday, January 14, 2024 at 7:25:57 PM UTC-6 John Hawrylak, Woodstown NJ wrote:
Chris made some good points. I am not justifying a heavy bike, merely pointing out what you can expect if you take that trip & 'go down the rabbit hole' wrt to reducing frame weight and overall weight including the rims/tires. You may not get your kicks on Rt 66 ('when you take that CA trip...")
Good point on wheels. If you maintain a constant speed, you minimize the acceleration and reduce the effect wheels have. But real world riding has a lot of acceleration , so lighter wheels help. The biggest effect was probably the change from STEEL RIMS to AL RIMS in rotational inertial.

if you just look at the numbers, you can go down a long rabbit hole and certainly justify a heavy bike.. I agree 1mph isn't anything.. what you can't justify with numbers is what a heavy bike feels like when riding.. some heavier bikes certainly can "ride light", but many don't in my experience.. same with heavier wheels or tires, my 650b Hilsen with Rich-built wheels and 42mm Compass tires do NOT feel like they spin up as well as my Serotta with HED Belgium tires with 28mm Vittoria Corsas on it..
I would never begrudge someone riding what they want to ride, but often, heavy is just that.. heavy..

During a appearance on The Opiniated Cyclist, Richard Schwinn stated the following: Reducing the bike weight by 12 lbm, increases your speed by 1 mph, given the same power input from testing Schwinn did.

It will always have a dyno hub. I just can’t give up that kind of practicality. I didn’t know Paul components would save me any weight but I’m glad if they do. My Velo Orange levers were pretty feather-light already though.
I probably do have the Platy set up as light as I dare, save the drivetrain stuff from White Industries. And Richard has a good point that all that money would only save me a third of a pound. Does the raspberry Platy still have a dyno hub? If so that would be a big gain as far as weight loss and lessening drag. Otherwise you have it set up fairly light from what I remember about your posts. Paul components will sure help shave some grams.
When weight is brought up the first thing Grant would say is take weight off the engine. Well I just took a massive amount of weight off the engine so I feel that I am now free and clear to be a weight weenie about the bike. :)
