Crazy things happen if you start weighing your bikes . . .

[exapkib]

This evening, while helping a friend to pack for an overseas voyage, we were using a hanging scale to weigh suitcases. I ran out to the garage with the scale to weigh my bikes. I don't know what came over me. I had never done this before. I ride without a computer, I don't weigh bikes or parts--just who I've always been. Apparently, people can change.

Long story short, the results are baffling.

My 'heavy' commuter (Black Mountain Cycles Monstercross) weighed in at 20.5 pounds.

My 'fast' road bike (Yamaguchi steel) weighed 21.8 pounds.

I'm guessing that the weight difference is mostly in the wheels--the purple bike has Mavic A119 rims laced to Record hubs. They feel heavy.

Just goes to show that a lot more goes into the way that a bike feels than weight. Preaching to the choir here (mostly), I know, but I'm still slightly baffled.

There is absolutely nothing lightweight about the components on the Yamaguchi unless maybe you count the Time pedals, so don't sweat it. It remains one of the most beautiful bikes.

That said, if it were mine I'd love to try it with a different set of wheels and tyres to see how much the ride characteristics etc changed.

I found the new Bora Once clincher to be transformative

Roger, gotcha. I can only imagine how you'd feel with some Veloflex Masters in 25 on those Bora's.

I built up a mid range circa 1990 60 cm Japanese bike this week with SunTour GPX and Sprint/Wolber tubular wheels. With a pound of Look pedals and cheap post/saddle/bar/stem, I wasn't surprised at the 23 lb. weight. What did surprise me was to see the weight of a similar vintage Italian SLX bike with Chorus listed on Bikepedia at 23.2 lbs. I always weigh my bikes when they are done. Very few have surprised me at how little they weighed. I have 10 lbs to give before I worry about the bike.

You can build very respectably light wheels with Campagnolo silver hubs. I don't know what spokes you've got, and those rims are a little beefy.

Next time you build them use HPlus Son TB14's and you'll save 100g on the rims. Anyway you can build up those wheels quite easily to around 1550g-1600g. I have two pairs. That's essentially Zonda level weight while preserveing the aesthetic.

All the stuff you have on that bike is pretty light for the era and comparable to today in many ways. The bike is heavy because it's steel with a steel fork. Likely you have 2600-2800g in that frame and fork. Even a cheap quality aluminium frame and full carbon fork will be only 1600g. High end carbon will be another 400g less. I have an extremely similar (weight/components) steel bike built up with a much less enviable frame, and I love it.

That bike should be, and is built around that beautiful frame and fork, and considering what it is and how it's built it's great. Don't sweat the weight and enjoy the ride.

Why not weigh the wheels? If the scale is inaccurate for light weights, tie the wheels together and weigh both at the same time, or weigh the bike with and without wheels and subtract. You just didn't go crazy *enough*...

As rain_dogs pointed out, it could be the frame. There's nothing wrong with a stout frame. People on this forum have praised heavy classic steel bikes like the MX Leader (never personally ridden one) for its stability, power transfer and descending prowess. How does your Yamaguchi handle?

By the way, I must say I'm taken with the gorgeous Utah scenery in your photos on this forum. Even your neighborhood is lovely.

as eluded to by pdmtong above, the feel of lighter, stiffer wheels on a sweet steel road bike can totally transform the ride.

if you get the opportunity (or create the opportunity), try some lighter wheels on that bike, carbon tubulars perhaps. you'll be surprised, for sure.

Wheels will make a huge difference in feel on the bike.

But don't discount parts for weight either. Last year I swapped the prior gen Campy 11 speed bits for the latest gen Rev+ stuff. Just replaced the brakes (albeit with ee's), crank, derailleurs and shifters. That swap dropped a pound from my Della Santa.

There's a reason I don't weigh my bikes: Ten posts into this slippery slope and this thread is getting expensive.

How much for that 454 grams? More than a $ per gram? Oppps..Not gonna get into this but if I lose a SDW(Standard Bike Weight=20 pounds)off me fat arse, my bike will weigh.....ZERO!!!

2nd this. swapping to some carbon wheels totally transformed a couple steel bikes for me. they already rode sweet, but putting the carbon on added a ton of stiffness and responsiveness that was never there otherwise. all the sudden, I had to look down to make sure I wasn't on my aluminum bike...

this, in my opinion, is the main reason people who don't race should look into carbon wheels. particularly low or mid-profile ones, where you don't notice any lag spinning them up. you add lots of stiffness and responsiveness, lose a tiny bit of weight, add a lot of fun.

This.

Note the original poster said not one word about how his bikes felt or his sense of speed or acceleration on them... he just was surprised by the weights.

Having had Hyperon tubulars (1230 gms) for more than 5 years, and substituting them in on various steel, titanium and carbon bikes, I think the gains are at the bare minimum 50% psychological. IMO.

Which is true for a lot of what we do to our bikes. And to ourselves.

Not that there's anything wrong with that...

The weight was really incidental. I wanted the new parts for the revised shifting and the silver Record dual pivots we're getting a bit tired. That and I thought the new Campy bits including the crank look awesome. Weight wasn't even really in the equation.

But if the side effect is bringing a steel frame/fork with a pretty beefy quill stem and no weight weenie parts to speak of down to 18 pounds, I won't look a gift horse in the mouth.

My point was merely to highlight that modern parts, even across one generation, can get you some weight savings if that's what you're going for.
