that klein is sweet

Just got some Deore XT pedals with plastic toe clips and nylon straps, weigh in at 430g.. will weigh the clips/straps separately later. They're replacing pedals that weighed 410g for the pair w/o clips & straps

you got that right buddy

Thrifty Bill's $3.- Ebay scale strikes again! I think this is Bill's master plan... as we strip quality vintage parts in a quest to skinny up our portly old trail bikes, watch for Bill's PM's to hit your inbox with an polite inquiry about the discarded components. I'm on to you Bill... "Thrifty Bill" morphs into "Sneaky Bill" the king of package deals!

Yeah, maybe I'm bitter since my Cimarron didn't hit Bill's 25 pound mark but I think my frame is bigger... yeah, that's it, bigger frame!!!
( More cowbell ! ! ! )

weighed Deore XTII thumbie vs Deore II thumbie: 97g vs 109gr


the main difference is probably the fact the XT thumbie has an alloy clamp. For drop bar conversion fans, the alloy clamp is less preferred since they don't fit drops like the steel ones do. I've considered filing down my XT clamp to make it fit but then it won't ever fit a flat bar again so i dunno. plus it will take a long time and could possibly look bad doing it with a hand file

Glennfordx4

You could always try snugging the bolt on the clamp down while off the bars and use a Master Cylinder Brake Hone to resize them, would look better and have an even bore ( more then with a file anyway).

I like this thread, although I don't own a bike scale to do weight comparisons I know every bike I build for myself comes out lighter then when I started, one mostly because I don't start with a high end bike to begin with ( in most cases, but there are exceptions ) so any component I replace is going to be better and lighter then the one I replaced.

One example is my 21" GT Outpost I am going to be building, nowhere near a top of the line bike & definitely not light weight as I'm sure it probably weighs more then 30lbs in stock form with the low end Suntour & SR components that were on it ( probably closer to 35lbs). Steel bars, seatpost, chain rings & freewheel hubs are only a few of the parts that weigh a ton on this frame that will be changed out for better, lighter & stronger components like alloy bars, seatpost, cassette hub & full XT drivetrain & brakes with a little bit of Ti hardware thrown in just for good measures I am sure I can get the weight below 25lbs when I'm done.

Just pulled out the Cimmaron for a couple more changes. Swapped out the pedals, and installed the Shimano 7 speed indexed barcons. Was hoping the Ti post I had scored would fit, wrong size. Damn.

So I am at 25.42 lbs right now. I added about a tenth of a pound to the weight by changing the saddle. The Fuji Ti saddle I have just looked too weird on this bike. To get this bike under 25 lbs is going to take either a wheel swap, or a component swap (limited myself up to now to what I had in hand, other than the pedals). I need to check the wheels on my wife's Trek 950. I started this exercise at over 30 pounds. Much easier to start with a light weight frame, like my wife's Prestige frame Paramount 70.

If anyone is looking for a possible wheelset upgrade for their MTB, bikewagon has a pretty good deal on ebay for Mavic XC717/Deore M590 wheelsets at $125 shipped: https://www.ebay.com/itm/271003995259

Mine arrived a week or two ago, but I just got my new SRAM PG850 cassette and kmc 8 speed chain yesterday.

Claimed wheelset weight is 2030g and that's probably with the included skewers. When I weighed my wheelset (without skewers and cassette) my postal scale was showing them around 1850g.

Ended up saving almost 2 lbs over the stock Deerhead XT/Araya 7x wheelset on my drop-bar Cimarron. My 23" Cimarron weighs in at a "svelte" 27.9 now with the Vetta rear rack (around 1.3lb), wheel stabilizer, kickstand etc, so it may be close to 26lb without them. I may pop them off to weigh it without at some point, but I ride it almost everyday and make full use of those accessories.

wrk101

I took a ride on them today. Grip wise, I would rate them a 5. I would rate my VP alloy bear traps a 10. The cheesy plastic platforms my wife likes I would rate a 1.

While they worked well for the weight reduction, and a 1/2 pound reduction for $29 is pretty remarkable, given the extra weight I am carrying anyway, I will probably stick with the bear traps. The bear traps are really awesome (please note, I wear a 4E shoe, so wide is good....)

My favorite toe clip style pedal remains the Shimano 600s. But getting XL clips has gotten really difficult.

Those are sweet wheels above BTW.

Good find on the wheelset. I plan to put something similar onto my Univega to replace the older, heavier richey 440's that are on there right now. I also just bought an Deore XT medium cage rear so that I can have 8 speeds in the rear. Spacing is 130mm so I may need to stretch it a little bit shouldnt be an issue.

I'm building an '87ish Alpina Uno with Midge bars so I've been following this and the drop bar conversion thread. Right now it weighs ~26lbs without brakes but with a 1000g front tire (my frame has the backwards cantilever bosses so I'm waiting for some compatible brakes to come in the mail) . I'm considering swapping it for something a bit lighter but want to maintain at least a 1.75 with a little tread. The rear tire is a Michelin Country Rock and putting another in front would drop almost a pound. I'll post some pictures and final weight when the build is finished.

These plastic Ezra pedals with metal pins don't look vintage but they are pretty light @ 340g, have big platforms, and incredible grip. I recently put a pair on my Volpe and the increased grip made a surprising difference. The pins are sharp so you need to be careful when moving the bike around but there's no worry about slipping off the pedals.

Just picked up a 1992 PDG Paramount 50 last night. Not only has this bike hardly ever been ridden it has a lot of upgrades to Deore XT. Basically this bike stock was specced with Deore DX, but someone went just nuts and put almost all XT on this thing...Rapidfire SLR 8 speed shifter/brake combo, XT rear derailleur, XT parralax hubs laced to mavic 217 SUP wheels ( very lightweight ), Selle San Marco Rolls saddle, Richey post, DX front derail/cranks/cantilevers. Weight is right now at 23.8. LOL. Ill post some pics soon, full tange Prestige frameset.

mainstreetexile 

I forgot to mention it, but the spacing on my Cimarron is 130mm too. I just spread the stays by hand as I put the rear wheel in, it wasn't too difficult, even with a rear rack mounted. It looks like the M590 rear hub has a long-ish spacer on the non-drive-side. You may be able to replace this with a smaller spacer (or spacers) and re-dish it to 130, that would make it usable on 126mm frames too.

Dropped the 1986 DB Axis from 31.8 to 28.8 by

swapping out the low end Shimano Altus RD for a nice Shimano 600 one
swapping out the steel 46t chainring for an alloy one
swapping out the kenda k838 tires for Panaracer Tserv
removing the fenders (1.2 lbs right there...)

The saddle bag it's carring .8 lbs or so too.. still have some steel handlebars i need to swap out too. I didn't get a chance to take pics but the new tires are much nicer... to the point i may need a larger chainring now .. i can't believe how much i liked the k838 tires cause both times i've swapped them out for different tires i've immediately jumped up a bunch of gear inches.. the tires are slightly smaller but i'm jumping up a lot more gears. When I swapped out from the K838s on my Univega I went from the spending most of my time in the small chain ring to almost only using the big one

30 years ago,in France, I bought this MTB in a supermarket named "euromarche".....I bought it because it was pretty and chromed , his name....MTB.....(I don't know the builder) , all CRMO frame, 18 speeds,DNP "climber " derailleurs (front and rear), crankset stainless steel and alloy (DOTEK), brakes "VANGUARD" , this MTB was built in Taiyan .
After 30 years, it is always in good conditions , I can say that it is a strong bike, but not a real climber because it is too heavy (35 Lbs).....! so , I ride it only on the plains , even with little hills, but not to climb mountains.....

frantik

oh man.. almost done building up the Jamis Dakar.. i've been weighing it as i've been adding things.. right now it's ~24.8 and it still needs bar tape and pedals. but it also needs some of the cables trimmed. i think it's going to weigh pretty much exactly 25 lbs without pedals.. but pedals with toe clips are gonna add close to a pound. if i can keep it under 26 with pedals, toe clips and bottle cages that won't be too bad

phoebeisis

The Jamis is 27.25lbs
The Trek 950 28.25

The Jamis frame is light-forget exact #-maybe 250 grams less than the Trek True Temper OX2-not a huge difference

It also has some VERY HEAVY parts-for comfort-
saddle in the 1100 gram range
disc obviously just being stored there
the adjust stem-probably 400+ grams
Handlebars-maybe 430 grams
sidestand extra 350 grams
seat post-maybe 350-400 grams
but it has very light wheels tires -
Hugi hub + 517 ft rim
400 gram tires
crossmax rear
Very light pedals-140 grams total-=seems low??-wellgo really cheap ebay-maybe 140 each??

The trek-some heavy stuff also
heavy saddle 650 grams
sidestand 350
big handlebars-400+ grams
400+ gram 36 tooth cassette
but light wheels-crossmax ft rear XTR hub 517 rim 400 gram tires

The jamis could go under 25 lbs with a 300 gram saddle-in 23 lbs range dumping side stand ADJ stem -disc-handle bar

They are tiny 13.5" frames-the Jamis is actually too small-hence the weird seat post
Anyone want to buy a tiny Jamis frame-suitable for folks just 4-10-5'3"-standover an honest 25" 10" up the top tube-where you would stand over it
I would sell the frame-but a 15.5 Jamis
Charlie
PS CF ALUMINUM OR Titanium EASILY 1-1.5 LBS less

PS Like others mentioned -wheels tires pedals are the best most cost effective switches
XTR hubbed 517 rims-front maybe 700 grams-200 less than an "average" combo-and not really expensive on ebay
400 gram 1.9 tires Kenda-maybe 200 grams saved over average steel bead tire-
so wheels tires can save 800 grams- wellgo pedals 200 grams saved for $30-can't beat that-
used XTR 517 wheelset maybe $200 on ebay??*(haven't checked in a while) Hugi 240 517 rims not lighter than XTR 517
if you can blow $80 get a XTR cassette-save 50-70 grams over LX

I read this thread the other day and it got me curious about my bike, I never bothered to weigh it before but it checks out at 20.8 lbs.

It's a 1992 Cadex (Giant) CFM-1 that I bought used back in 93, and still think it's a cool bike



No catastrophic frame explosions yet

Sixty Fiver

Mouldon custom circa 1990 - 23 pounds with pedals.

Was lighter with the Race Face Carbon crank I was running and was 21 pounds as a singlespeed (my initial build).

Frame is built with some ultra light 853 Reynolds and Prestige tubing and the parts are nice but there is nothing weeny-ish about the build... but I started with a frame and fork that is as light as my custom road frames.

The Hurricane tyres are a weighty 650 grams each , thinking that if I replace them with or run a set of Furious Freds I will knock 710 grams (1.5 pounds) off the bike which would bring it down to 21.5 pounds.

Those Hurricanes are great tyres as they roll out exceptionally well and have been bulletproof for more than 12,000 km.

My 725 framed Rocky Mountain Blizzard weighs 26 pounds when it is rolling on those wire bead 2.35 Nevegals that weigh 1300 grams each (but these stick like glue on the trail)... on it's lighter Specialized folders it curbs out at 24 pounds.



Have been weighing parts for my Kona Explosif build... should have a sub 20 pound SS MTB when I am done.

frantik

25.6 lbs as pictured. 24.94 without pedals

I'm hoping i can keep it under 26lbs with a bottle cage and toe clips. I dropped about lbs off the bike from when I purchased it, mostly with a wheel and tire swap. I also swapped the stem and did a drop bar conversion.. not sure which cockpit would weigh more (i suspect a flat bar setup would be lighter though) Tange Prestige MTB frame with mostly Deore XT

Tires are 440g.. I could go with the smaller compass tire and drop about 100g each tire, getting me very close to 25 lbs, but even the 1.75" tires are a bit small for my taste.

Still dialing in the fit on this one.. SixtyFiver i think I need one of your lightweight dirt drop stems [and yeah that saddle angle is a bit extreme, even for me.. haven't touched the saddle adjustment since i bought the bike tbh]

Sixty Fiver

The dirt drop stems are not that light being that they are chromed steel... mind you they lose some weight because they do not have a conventional stem bolt and are damn sexy.

Will have to weigh them up and see where they sit.

frantik

oh i think i just assumed since you had them that they were light .. they are damn sexy though for sure

papik

Abetter view of this MTB......

Sixty Fiver

I have never been accused of being a weight weenie before, I spend very little and like you usually use what I have kicking around the shop.

Swapping the tyres on my Moulden won't happen until I wear out those Hurricanes as they are still in fine condition, would have looked at the kevlar version but those are no longer available.

For a rigid mtb it only weighs a few more pounds than my hand built road bike and rolls out just about as fast. I have road slicks for it as well but the ride on 1 inch skinnies is brutal as it is also very stiff.

No one has mentioned brakes. Year back I replaced the original brakes (Alivio?) that came on my Trek 930 with Shimano STX? — I think they are. A few years back I had them dismounted and so held the front and rear as a set in my paws. OMG ... they weighed a LOT! They stop like gangbusters — a good thing. But I have been thinking that there has to be a decent brake set that weighs half of these. The Alivios — or whatever they were — are too feeble for street-fighting in down traffic.

Glennfordx4

Damn Frantik, I don't like drop bars on my MTB's but that Dakar is killer looking, nice job!

Picked up two mint sets of canti's off Ebay from the same seller ( relisted at that), a set of BR-M734 XT's & a set of BR-MT62 Deore 2's with all the hardware for both sets, $30 shipped. I like the Deore 2's & I am going to weigh them on my postage scale just to see what the difference in weight is between the two sets, if the Deore 2's are less or close to the XT's then they are going on my Paramount Series 70 which has a stuck seat post right now, I'm taking my time as it has the stock Ritchey post I want to try & save.
