picked up a park hanging scale and started putting stuff on it in the garage to see what i've been riding all this time.

two complete bikes

time vx edge with sram force and handbuilt wheels = 18.1 lbs

new columbus life/edge fork with campy chorus 10s (ut version) and campy eurus wheels = 19.4 lbs

these are riding weights, meaning i was just screwing around so i didn't bother to remove the bottle cages or saddle bags or whatever else i've got on there like lights and computer etc...

heavier than i expected, but i'm happy with the bikes so.....

Now that you know how much it weighs, you're gonna be weight weenieing your bike part by part. ;)

I have a Litespeed C2 w/ FlashPoint FP60s (boat anchors @ nearly 1900g), DA7800 grouppo, 18.0 lbs on the nose. I have since knocked off a couple grams w/ a BB30 crankset and a lighter carbon bottle cage. I probably won't get anywhere near the "magical" 6.8kg/15 lbs until I get some lighter wheels.

My girlfriend's bike is ~24 lbs, BB7 disc brakes, Nashbar aluminum cross frame, Nashbar cross fork, 700x30 Schwalbe cross tires, Bontrager disc wheels (2100g), Sora levers and crank, nothing lightweight anywhere.

I haven't seen that weight in about 40 years, I think I was in middle school and about 12 years old! I'm jealous...but at 6' 3" that might be a little thin for me!

Calfee Dragonfly: 14lbs 14oz.
Look KG 171: 18lbs 4oz.

All weights are ready to ride with pedals and cages. I love them equally.

The LBS weighed the the 58 cm K. Bedford at 19' 9 oz wth pedals. Not equipped with light wheels and components. I did not buy it to be a light bike, but that seems pretty light for a steel road bike.

I don't really know. But then I think weight, or a lack thereof, is overrated, particularly when a guy on a mid-80s Ciocc with 32-spoke box wheels passes me up hill on a 42-chainwheel; he doing so while I'm on my c/f bike with modern STI. :rolleyes:

I don't know, I only ever weighed one of my bikes once, & that was 2 years ago when I had my backup wheelset on it...but fwiw, with older (~2006) Ksyrium Elites and pedals, cages, & computer still attached, it weighed 18.1lbs. My main wheels (DT Swiss 240S hubs, RR1.1 rims, & 28 SuperComp spokes, handbuilt by Joe Young) are allegedly 300g lighter, so you do the math.

You oughtta also ask how much does the rider weigh.

Bigger part of the equation, means so much more, much easier and cheaper to reduce the poundage.

My lugged steel Waterford with a 1989 C-Record Delta group, sewups is 1 SBW...I weigh 10 SBWs.





'SBW"-Standard Bike Weight which equals 20 pounds or 9080 grams.

My heaviest bike is my Cannondale tandem at 1.75 SBW. Based on your system, after the first 20 miles of a ride my wife normally adds another 5 SBW of dead weight. Total about 135 pounds.

Yet in spite of pushing all that extra weight I enjoy riding tandem with her more than riding my lightest single bike. Weight, or lack thereof, doesn’t add much enjoyment to my rides if at all. I get that in competition it’s a means to an end, but when riding for pleasure a lighter bike doesn’t do much for me.

I agree that weight is overblown, but there is something to more weight... it HAS to take more energy to propel a 20# bike up an 8% incline than it does a 15# bike at a given speed... now, how much more energy is debatable and losing body weight would be more efficient I'm sure... but, I guess what I'm saying is you can't automatically write off bike weight at meaningless I don't think...

besides, if we, as riders, just worried about riding and not the looks, components, weight, or name on the downtube then we would all be riding the same non-desript bike... part of cycling is being able to differentiate ourselves/our bikes by name, parts and/or weight ***

I weigh my bikes as I ride them with a full saddle bag... the only thing I put in my jersey is my soulrun jerseywallet with my phone, id, credit card, and a couple dollars... maybe adds a 1/2 pound at the most...

but, I agree... weights should as the bike leaves the garage maybe minus water bottles...

Black Dog
03-26-2011, 10:17 AM
All very true. I would add about 1 pound for saddle bag and mini pump. And about 3 pounds for full water bottles and 165 pounds for the pink ape that turns the pedals.

Perhaps the bike mass should be listed as a percentage of the total rider+bike package or as a rider to bike ratio.

No harm taken. You are right that it is easier to ride a lighter bike up a hill than a heavier one. True. However, the differences (when the total bike plus rider mass is considered) are very small and fall within the fraction of a % range.

Objectively, it is definitely not meaningless and its magnitude shouldn’t be open to debate since it can be calculated precisely. Subjectively, whether it should be important or not to a given rider is what’s debatable.

Personally I believe it’s up to the rider to decide what’s important to them -- some don’t care about 5 pounds and others care about 5 grams. :beer:

I guess what I meant when I said "how much energy is debatable" was the perceived amount of energy required... an extra 2 watts may be nothing to one person and whole lot to someone else...

that's one reason why I love cycling.. so many ways to objectively "improve" performance... :)

Well, sure, but for that matter, few of us ride around with a scale! You have to really go out of your way to weigh a bike; there's nothing about riding a bike that requires that you ever weigh it.

So the reality is, bike weight has nothing to do with bike riding.

That being said, once you accept that bike weight is an interesting topic of conversation for people who also ride bikes, the REAL world dictates that extraneous parts that aren't attached to the bike don't get weighed with the bike. Imagine if your bike was a house and you had to itemize which parts would receive a capitol improvement tax deduction. If it qualifies, it stays on & gets weighed; if not, weigh it without.

It has always mattered to me, but not in the typical ways as a rider. What counts to me, and the reason to get the weight down is for portability. Unlike running, transporting gear in and out is required for the sport and it sometimes turns into a time killer and ordeal. A 20 lb bike is/was a lot easier to lift onto a roof rack (when I had one) than a 30 lb bike.
As someone once told me, you want a lighter bike, go lose 10 lbs. What is really cool (like I've ever done it) is to show up on a 30 lb bike and toast everyone with your fitness.

Yes, fitness, blood profiles and genetics trump bike weight every time. And no matter how expensive and light your running shoes are, the same holds true. Yet everyone that is an active runner likes good lightweight shoes.

In the end, every pound counts, its just a question of how much it means to you. The easiest way to obtain a marked improvement in climbing is to lose weight. And for the quickest and most pronounced results, focus on the belly. Once you're lean and mean, then focus on the bike. Lightweight bikes, in general, also exude more agile and connected handling characteristics in my opinion. They are my cup of tea for the most part, but your mileage may vary.

The bike that I ride weights way too much and unfortunately so do I right now. A few years back I had a very nice vintage butted tange 2 steel road bike with a complete Suntour Superbe Pro group set. It was the lightest bike I have owned and used and the one thing that has stuck in my memory is how easy it was to climb up hills.

My commuter mountain bike conversion really needs the low end granny gears to be rideable. I recently swapped out the wheels (maybe a little weight saving) and went from Schwalbe Marathons to Marathon Supreme (about half the weight) and the bike seems noticeably more lively.

Now if I could drop the extra 20 pounds I am currently carrying around, I feel absolutely confident that my bike ride will come alive. ;)

I have an XL Look 585 built with Chorus shifters and derailleurs, Centaur cranks, Ritchey bars and stem, Thomson seatpost, Arione saddle and Ligero wheels (1396gms.)

15.5 pounds with pedals, cages, and a computer.

The bike freakin' flys.

My similarly equipped Pegoretti is a gorgeous ride, same components, different wheels (60gms heavier,) may 18-19 pounds. It's just not as quick as the Look.

That being said, if I had to choose just one, it would probably be the Peg.

Weight makes a difference, but it's not the necessarily the most important one.

I fully agree with DonH my Steel Hampsten Pro with Campy Chorus heading out the door is twenty lbs but riding up Mt. Baker it is snappy as I jump on it in the switch backs and on the decents it is planted to the road like it is on rails. Yes loseing a few pounds of body weight is cheaper and usually one feels more benifit in overall health.

Are you sure it is not you thinking the one should be faster than the other? Perhaps one is stiffer and has more agressive handleing?

A few pounds is on the limit of what is detectable. Try this on the Look. Have a friend put in two non-transparent water bottles on the look and take it for a spin. Here is the catch. You will not know if the bottles are full or empty. Do this 10 times and each time record whether you think that they were full or empty. This mass of the water will be about the same as the difference between your bikes. If you can tell then it is safe to say that you really do notice mass differences on that scale. If you are scoring better than 50% then you can tell.

This was done for me when I was young a thought that my bike was too heavy; my coach (A hard-assed former Belgian National Coach :no: ) told me to shut up and ride and that the weight did not matter and thinking it mattered made me slower :crap: . Well, everything that was not his directive made me slower by his logic. The results were that I could not tell, I was guessing no better than random chance. :confused:

It is good fun.

Someone once told me, if you think your bike is slowing you down..it is. By extension if you think it's making you faster, it is.

So much of cycling takes place between your ears.

Are you sure it is not you thinking the one should be faster than the other? Perhaps one is stiffer and has more agressive handleing?

A few pounds is on the limit of what is detectable. Try this on the Look. Have a friend put in two non-transparent water bottles on the look and take it for a spin. Here is the catch. You will not know if the bottles are full or empty. Do this 10 times and each time record whether you think that they were full or empty. This mass of the water will be about the same as the difference between your bikes. If you can tell then it is safe to say that you really do notice mass differences on that scale. If you are scoring better than 50% then you can tell.

This was done for me when I was young a thought that my bike was too heavy; my coach (A hard-assed former Belgian National Coach :no: ) told me to shut up and ride and that the weight did not matter and thinking it mattered made me slower :crap: . Well, everything that was not his directive made me slower by his logic. The results were that I could not tell, I was guessing no better than random chance. :confused:

It is good fun.

Now this is a Surly Pugsley outfitted with bags and racks for a snow bike race. I've got more in my 2 wheels than many do in their entire bike.
