    Confused as well. Not sure I understand "extrapolate back." (I understand the term, just not how it's specifically applied here.) It almost seems like there might be double counting in there somewhere.

    You'll never see pictures of it outside, let alone a gravel road, smooth double track, or a rock strewn trail.

    I think there's another 1/2 lb to even 1lb available to shed, but that depends on your budget. With reasonable selections to several components (rubber, saddle, bars, bolts, grips), the loss can add up. BTW, don't see any wheel hardware (axles) listed.

    Also, is there an adapter on your front rotor to obtain the 180mm? Can you get away with 160, and also drop the adapter?

    Lastly, after frame and wheels (including rubber), your next heaviest component percentage-wise is the dropper. I realize you like it, but that's >1 lb right there from stock Scalpel.
    The wheels, ready to ride, were 3.48 lbs and 4.56 lbs. I subtracted Schwalbe's listed tire weight, actual rotor and screw weights, 60g for sealant and rim strips, and the cassette weight from the rear wheel. The result was what's in the spreadsheet.

    EDIT: Schwalbe is full of crap. I just pulled apart the front wheel. After clearing out some gunk, I get 699g each for both the front wheel (excluding rotor) and the tire. If the rear tire weighs the same, the rear wheel is 977g. So, about 1.67kg, including stickers and a full-width rubber rim strip. I don't know how BikeRadar got a number 150g less for a set with Chris King hubs. The Lefty hub is lighter than a DT 240 and the DT 350 doesn't appear any heavier than the CK's.

    I went out of my way to add the dropper. The head angle on this bike is 71.4 and the the stock stem is super-long, so it wants to pitch me over the bars on some of the local downhills. The extra pound hurts, definitely, but the post builds a lot of confidence.

    I think the axles are part of Cannondale's quoted frame weight. There's some fudge factor here, relying on third-party weights; I haven't stripped the thing down to weigh it myself. Same with the Lefty. Lots of people say they're getting 1.3kg or so; Art's Cyclery says 1402g. The total for the bike is almost spot-on.

    There's a single bracket on the front for the 180mm rotors. I'd be more likely to choose a thinner rotor than to drop the diameter, I weigh too much for anything smaller on 29 wheels.

    I don't know what it is about tires, but for whatever reason no 2 of them are ever the same weight. They make them at the same time, at the same place, in the same machine, with the same amount of "goop", yet the variability is ridiculous - and not just with Schwalbe.

    As for the dropper, I'm not against it by any means, but yes, it goes counter to weight goals for sure.

    A fair number of bikes seem to be "over-braked" at the factory, especially for smaller riders. I suspect this somehow relates to litigation concerns in the US. In any event, it's always nice to remove an adapter, and lose weight that way, and buy a smaller rotor. However, if you are larger and are conscious of your brake needs, then of course retain the 180. You can try KCNC as they are inexpensive, although I've found the cutouts are a bit aggressive, and there's a bit of a grab penalty for that. YMMV.

    115g is a hell of a difference, even accounting for what was probably 50g of baked-in sealant. The Maxxis tires were respectively 6g lighter and 4g heavier than quoted.

    It also turns out the previous owner had left in an ocean of sealant in the rear wheel. The tire weight is still accurate, but the correct wheel weight is: 699g front, 852g rear. 1551g. That's very reasonable. If these narrow rims don't squirm with the 2.35" Maxxis tires, I won't have much reason to upgrade them.

    Current weight is now 10.64 Kg, though that's without sealant. I'll look into KCNC, thanks. The pricing is pretty reasonable.

    Hey, Crossmaxx. Been a year. How are the trails in Sweden? Still no riding here--8 inches of fresh snow since Wednesday night.

    Did you measure the before and after on that steerer? I'm curious, I have the same alloy 321 steerer (amusingly on a Scalpel; I wanted to run a non-OPI stem) and it wasn't that heavy to start.

    I have built a race-ready, more or less weight weenie bike for this race season. With rigid fork.
    Handlebar, seatpost and seatpost clamp still "heavy" (180g, 240g and 51 g) so there are still some room for further improvement. Oh, and derailleur is only an XT (~270g), shifter is also an XT (122g), etc.
    Still, it's my lightest bike ever. Including my road bike, which is 9,1 kg...

    FYI, the wheelset is an Acros XC Race 29 carbon, I measured 595g for the front and 700g for the rear wheel. :-) Rims are Duke Lucky Jack 29, 25mm internal rim width.

    This is my 7.7kg Scott Scale 29er
    Post your light-weight bikes!-scott_scale.jpg

    Its got heavy pedals on it. I have yet to put SPD pedals on and I have some solid carbon forks that will get it down to around 6.7kg if I wanted it really light, but I like it more 'usable' rather than being a no suspension bike.

    This is its little brother. A 26er Scale 35 which is about 8.2kg in this picture

    I wouldn't say it's cheating as 26" wheels are still being used today - 24" would be cheating (I have seen a custom build with 24" wheels and it just looks wrong) . 26/27.5/29 are all MTB wheel sizes .

    Steerer is too far above the frame . It is a carbon steerer so more delicate than a metal version .Shorten the steerer and get a high rise stem .

    It's slightly less than two inches. Lauf doesn't state a restriction on their installation guide. I'm an old fart. Almost all my bikes look like that.

    No more than 30mm spacers below the stem . You have way more than that .

    Nice, a lot of great builds showing up lately! Nicely-chosen components too.

    This is why I have to keep upgrading - jerks!

    I'd like to draw the attention to this thread on the weightweenies forum.

    If there was a Oscar for weightweenies I'd give it to this guy:
    Scott RC Scale/Spark 900 SL (Goal: sub6,6kg/sub8kg) - Weight Weenies

    Couldn't do that. Those were some good looking frames and the paint is just not worth it to me. I'll keep the extra 60g or whatever he said it was.

    Impressive though.

    Some great looking bikes here! Here's another from the black & gold family; a Scott Scale SL that I'm finishing up for my son. This is my first mtb build, and I wasn't setting out for a true ww build, but it's coming out pretty good.

    Post your light-weight bikes!-scott-sl.jpg

    17.85# sans pedals (not trying to cheat the weigh-in, but he hasn't found pedals that he likes yet). He has Ritchey WCS pedals currently, but doesn't care for them. Any replacement suggestions? Xpedo or XTR?'s He's about 125#, so something with Ti spindles would work. Post your light-weight bikes!-scott-sl.jpg

    Nice build, especially for a first stab at it.

    Crank Bros Eggbeater 11 are about as light as you'll find in a mainstream pedal. I run them myself, and they just happen to be gold:

    Thanks phlegm; I had my eye on those. I had a pair of CB Candy's on my bike, but found the release inconsistent on those (locked me in on an aborted rock-garden run, followed a finger bent 90 degrees in the opposite direction of what it should have been). Do the Eggbeaters and Candys share the same spring/retention, or are they a bit different between the two?

    I've never used the Candys, but the mechanism obviously appears to be the same, although I can't confirm.

    Your only choices are cleat orientation for release degrees, and the shim which can help/hurt depending on the shoes.

    Giant Anthem

    I have been busy with a custom Anthem build for some time.
    I find it hilarious that most bike manufacturers claimed weights are so wrong. The vast majority quote weights with showroom tyres and no pedals.... I also wanted to build a light weight aluminum bike that was race ready and not just built to hang on a scale. This bike races almost every weekend and bombs through rock gardens with no fear of punctures/breakage.

    Anyway my build is as follows:

    27.5 Anthem Aluxx frame. (2014)
    Kcnc handlebar and stem. Scandium
    ESI grips
    Kcnc seat post scandium
    Selle Italia SLR TT saddle
    ZTR crest wheels/ thirteen hubs
    Raceface next G4 crank
    XTR pedals
    XT drivetrain 1x11/ 11-42
    XT brakes/ custom discs
    Rockshox SID World Cup XX fork
    Conti raceking protection tyres

    Weight 10.3kg/ 10.6 (with pedals)

    Thoughts? Thanks... will post a pic when I get to my laptop.

    Bit late to the party...but I have three pairs of CB pedals (Eggbeater, Candy, and Mallet 3's) the release tension on all of them feel the same to me.

    That Giant is nice!

    Just an idea but taking a look to that extremely light hardtail probably a new topic would be created for 'fair play' purposes , like 'Post your light-weight, race-ready and race-proven bikes'!

    FYI, the wheelset is an Acros XC Race 29 carbon, I measured 595g for the front and 700g for the rear wheel. :-) Rims are Duke Lucky Jack 29, 25mm internal rim width.
    What tires are on these and what's the weight with the tires? Thanks

    Front tire: Maxxis Ikon 2.35 TR 3C MaxxSpeed, 705g
    Rear tire: Maxxis Ikon 2.2 TR EXO 3C MaxxSpeed, 625g
    70-80ml Stans No Flats Race sealant used. Unfortunately I haven't measured the wheelset with those tires installed.

    Setup sligtly changed in the recent 2 months, front tire is a Rocket Ron 2.25 SnakeSkin LTR now (~610g), rear tire is a Maxxis Aspen 2.1 TR EXO (630g) and front fork has been also changed to a DT Swiss OPM O.L.. Stem also changed from Syntace F149 (titanium screws version, 120g) to a 90 mm PRC 17° (also Ti-screws) which is 106g and gives me a more comfortable position. Actually I changed it only because of the purpose of lowering the handlebar a bit.

    (Current weight? Good question, I will measure it soon.)

    Yup that always gets people talking . It is comfortable . Selle SMP and Becker Carbon also make half saddles . TBH if I added the nose which I could easily do it would only add another 12 or so grams so wouldn't make an overall difference but to me that is unnecessary weight as it isn't needed .

    I never disliked it! Lol....I actually think it make sense and on the first version without the nose it looks also easier to tuck sitting on the top tube for better aerodynamics on the downhills, more room for the body...just make those front edges round (about 5g less....lol)

    8.590kg (18.9lbs)

    Now this weight is with a large aluminium frame so I'm not doing myself any favours to get the weight down but this is a start . A lot of parts are left overs from my other project and others are new and modified . This is the weight I am starting at and I aim to get it below 7kg although this could take a while . Definitely will be ditching the frame for a medium carbon .

    Blast from the past

    Let me land the time machine here and roll out what may be a Granddaddy of WW bikes. Back when I spec'd this bike out it was more referred to as "Counting Grams". When I originally picked out the brakes they were going to be a light weight set of cantilevers. The bike shop manager called me and said that I may want to rethink the brake selection. They had just gotten a visit from the Shimano rep and had a demonstration of their new V-brakes. Disk brakes were extremely rare and super heavy at the time. Suspension forks had only been out in the mainstream for a few years. Full suspension bikes were also limited and carbon fiber was just making it's way into the bike world. Here are the spec's on my 1995 Specialized M2 Stumpjumper FS. I still have and ride this bike today.

    Frame: Specialized M2 Stumpjumper FS 18"
    Fork: Manitou Mach 5 SX (AL)

    Headset: Dia Compe Kontac DL
    Stem: Kore Lite 150mm 0 rise w Ti bolts
    Stem Cap: Club Roost w AL bolt
    Handlebar: Scott Thermoplastic LFX 120g
    Grips: Specialized S Works
    Barends: Specialized A1 Dirt Rods w Ti bolts

    Brakes: Shimano XT w Ti bolts
    Brake Pads: Shimano XT w Ti nut
    Brake levers/shifters: Shimano XT rapid fire 8 spd w Ti bolts
    Front Derailleur: Shimano XT w Ti bolts
    Rear Derailleur: Shimano XT w Ti bolts
    Cables: Shimano
    Cassette: Shimano M737 8spd 11-28
    Chain: Shimano HG90
    Cranks: Kooka Vader w AL bolts
    Chainrings: Shimano XT 20, 32, 44 w AL bolts
    Bottom Bracket: TNT Hard Drive Ti
    Pedals: Shimano M747 with Action Tec hollow Ti spindles

    Hub Skewers: Kore Elite Ti
    Rims: Mavic 217 sup 32 hole
    Hubs: TNT Hard Drive Ti
    Nipples: DT aluminium
    Spokes: DT Revolution DB 1.8x1.5x1.8 261mm F 263 mm B
    Tires: Specialized Team Control F/Master B 1.95's (Fatboy slicks/road)
    Tubes:Specialized Ultra Light

    Saddle: Selle italia Flite Ti
    Seatpost: Specialized (Tohoma) 30.9x350 w Ti bolts
    Seatpost Binder: Specialized with custom Ti bolt

    Bottle cage: Schwinn AL w AL bolts

    Bike hits the scale at 20.76 lbs/9.44 kgs/9,436 g as pictured above.

    I've recently changed out my seat for a new Flite Ti Flow and the seatpost is now a Thomson Masterpiece 0 offset (silver). I also have a couple other vintage Kore stems that are shorter and have more rise to play around with so I'm not so stretched out. It was fine a couple of decades ago but, not so easy on my 50 + year old back now. These changes should increase comfort quite a bit.
    This winter I'm going to have the rear derailleur inside cage machined out of aluminum. I'm also going to have some material machined away from the seatpost clamp and redo the Ti bolt. Then there are some Ti bolts that I will replace with AL ones as well as some lighter jockey wheels. I'm not interested in changing out a lot of parts on this bike as I want to keep it looking vintage. With these changes it should drop to sub 20 pounds or right around 9 kg even. I only ride with the Master tires on special occasions to reduce their wear. They are in great shape still despite their age. I still use the Fatboy slicks for road and paved trail riding. Otherwise I've used more modern off road tires throughout the years. Next year I'll likely go with Ron/Ralph combo.
    I had this bike built for when I was racing and to be an express elevator for taking my 200 lb can up the face of ski hills around here, and that's what it did in my youth. This bike in its lifetime has also seen as much air time as your average 747. Much less nowadays for the long climbs and flights, but just as fun as ever turning circles whether it in the woods or pavement.
