Riding but otherwise stuck at home. And, I have a Park digital scale. You gotta know where this is going. So, I took my steel Guru and my CAAD 12 and weighed them. The Guru and the CAAD 12 are both a 54/55 frame size. The Guru w/SRAM Red, an Italian Road Bike mirror, Garmin mount, and 2 water bottles (1 is CF and 1 plastic) weighs in at 17 lb 14 oz. The CAAD 12 with 105, Garmin mount, Italian Road Bike mirror and 1 water bottle (plastic) weighs in at 17 lb 10 oz. Both bikes have Mavic Ksyrium Elite tubeless. I have to get another hobby.

Lol - why not add a little water, to make them equal?

Not surprising. A good steel frame, made of air-hardened tubing, is not that much heavier than a comparable cf frame. (And I'll bet your Guru has a cf fork?) Also, your steel bike has some lighter components.

FWIW the CAAD is AL. The Guru is Columbus Spirit tubing. And, yes. they both have CF forks. About components....correct. SRAM Red is much lighter than 105. If I had it to do over, assuming no sale, I'd love to have a CAAD 12 or 13 with SRAM Red. Might be a Lb. lighter. I don't know. But, God help me I have a Park scale.

You could always ride that nice Duck. Just don’t try weighing it with your Park scale.

I like my scale for kid's bikes, nothing like finding out you saved 2lbs with 2 tires that also perform better or that the deadweight steel handlebar does weigh a lb more then an old aluminum take off. It has let me pick the areas that make the most difference. Like a basic single wall rim is lighter then a better double wall but even with doing dirt jumps and rock gardens 60lb kids on 32h rims just don't stress the lighter, weaker rim enough to matter but having a bike 1/3 their weight does.
I do have to constantly remind myself that I need to worry about a few ounces on me before worrying about them on the bikes. Still cool knowing the road bike is 16lb 10oz though.

I’m happier not owning a scale, but I understand the compulsion.

I say get another scale and use each scale to weigh the other scale.

I can't imagine trying to lift it to get on my Park scale.

Swap the groupsets and report back with the new weight of each bike.

Heck, I've swapped seats between bikes, and thinking of swapping them back!

I've thought of it but I love that steel Guru and enjoy both of them for what they are. And, given my age and reluctance to get really fit, it probably wouldn't matter all that much.

Wow, when I read this the first time, I had mis-read it to say 'a' duck. Cue the movie dialog: "What else floats on water" "A duck!" and it goes on from there - and We must use my largest scales" (Yeah, I'm a huge Monty Python and the Holy Grail geek.) Movie dialogs just pop into my head all the time...

I thought this was going to also involve a drill and end with some holes in a frame.

Inspired by another thread, I redid the mount for the blinky light, saving 18g.

No, you don't need another hobby, Just do the work to find a COVID-safe way to find that Park scale another home. I have two scales. But what I have to do ti weigh a bike accurately is more work than I am willing to do. I have an old (but descent) floor scale. Pretty accurate at my weight but I cannot see the gradations to better than 4 oz. (I weigh myself before I go to the doctor.) Other scale is a digital CJ4000 for weighing coffee beans. Goes to 4kg. Putting a frame on it is doable but not easy

So I know my bikes' weights to around a 1/2 pound. Refuse to obsess about it.

That coffee scale does come in very useful for Cycle Oregon. 60 pound bag limit. I bag with everything except that day's ride. Years ago I weight everything and made up a spreadsheet. Now I just copy the spreadsheet, knock off a few items I don't want this year, weigh the new ones and know to within a half pound what the bag will weigh. (Until last year. It rained the first 4 days. Bag kept getting heavier every day. Every morning my wet tent and damp clothes, sleeping bag and everything else got stuffed into that waterproof bag and zipped shut. Drying never happened until the afternoon of day 4 Sadly for the kids who loaded our bags. mine was not an exception.

My velomobiles weighs 79 lbs.


I can keep up with most bikes until we get to long hills. They just start faster than I do....
