    Idea! Weighed my black Goblin

    Was curious since I'm planning to upgrade the wheelset soon so I weighed my bike for a baseline:

    27.8 pounds or 12,610 grams.

    This is after saving about 270g by swapping to a 169g carbon bar (stock was 339g) and lighter seatpost (240g versus 349g stock).

    I can probably drop another 2-3lbs by going tubeless with carbon wheels and lighter tires.

    Is this still with tubes on the stock wheelset?

    Yes. Stock tubes, tires and wheels. I have only replaced the handlebars, seat post, stem and chain. (New is SRAM PC 1091R with hollow links, might be lighter than stock.)

    Wheels/tires will make a huge change.

    I'm running Black Flag Pros and S-Works Renegade in back and S-Works Fastrack in front...both set up tubeless. Prior to that my bike had some other mods that didn't change the weight much. Like yours, mine was at around 28.3lbs. with MG-1 pedals. Oh, and it's a 16".

    After the wheels/tires, the weight dropped to 25.3lbs. I also changed to 1x10 which dropped the total weight to about 24.4lbs., and that's with stock stem, bars and seat post.

    Wow! I was hoping for a nice reduction but that's just excellent!

    Yeah, the real weight in a Goblin is those wheels/tires/tubes. The wheelset saves around 1.5lbs but a simple change to a lightweight tire can save another 1.5lbs easily.

    I hope I can find some tires that are light but still have the tread I need for the terrain around here. The AKA are OK but heavy as hell for how paper thin they are.

    I loved my tubeless Ignitor and High Roller combination when I had my 26er.

    Obviously if you want to save some $$ but want to lighten it right away, you can get the Stans kit for the Speed Disk wheels and just get a lighter tire. Even with the weight of the Stans, there is still around 1.5lbs to be had on the cheap. The Geax AKAs are pretty badly understated for weight. I and others have weighed them. They are closer to 900g than the advertised 750g. Even if you figured that the Stans kit would be roughly the weight of a tube, a couple of 550g tires would save you about 700g

    That's a good point. I only have experience with Bontrager rim strips (not tape) when going tubeless but I guess I can give it the college try. When I converted a set of Dusters before I used UST tires and no sealant.

    Guess I could get the valves (already have sealant), tape and some tires and that would hold me over for the new carbon set.

    Just out of curiosity, what wheelset are you getting? And what is the advertised weight?

    I found that the BFs were at 1800g set up for QR with the rim strips already installed. So they were pretty accurate in their claim of 1725g.

    I think I'm going to jump on the Light Bicycle wheelset at around 1460g for the set.

    My second choice are the Stans Arch EX but they're a bit heavier.

    Pardon my ignorance but what's "BF"?

    BF = Black Flag

    Wow! Those are light. Gives you a little more leeway to get a heavier tire for your riding style and location.

    Ahh, Black Flag... I've heard good things about those.

    My only concern is that I'm 230lbs right now and that's right at the weight limit for the carbon wheels. I could stand to lose a few pounds though... only 15-20 though as after that it would have to be muscle.

    Guess I should look up the weight limit of the Arch Ex...

    I dont know about the Goblin wheelset, but even the FlowEX's are lighter than the wheelset on my Seeker, and super durable.

    Hey iso - I was reading up on those wheels and they mention Shimano cassettes only. Are you going to change out your SRAM to get that wheelset to work or will it even matter?

    Well crap. I didn't realize that! Hmm... I wonder if hub choice makes a difference. Perhaps I'll just get the rims and have the LBS build them up with hubs I provide.

    My replacement wheel is on the way set to arrive today so I yanked off the stock rear wheel assembly and weighed it. This is with wheel, tube, tire, rotor, cassette and skewer.

    You might want to sit down for this...

    2955g! That's 6.5lbs in rear wheel only. HOLY!

    WOW! That is nuts! It's hard to believe that most the weight of the bike is from the wheels. I can say that mine probably weighs a bit more as I use thick walled tubes and 4oz of slime to keep the goatheads at bay. I have been looking at wheelsets myself, but cannot justify the funds at the moment, especially with christmas right around the corner.

    I weighed the front wheel assembly, complete just a minute ago. It's 2338g. That makes the total stock setup 5293g or 11.6lbs.

    My Geax AKA tire weighed in even heavier that someone else's at 926g. That's just insane. You can go full UST for less than that.

    The rear wheel/hub bare is 1243g... and if the weight of those light-bike Carbon wheels is to be believed at 1460 for BOTH... that's just... amazing. WANT.

    I know what you mean good sir! I have way too many bike outlet stores set to favorites, and love looking for killer deals. I have a set of Conti Trails ready to go on the bike once I finish murdering the Geax tread, but, I see some Ignitors with a kevlar bead weighing in a 575g's each. I am not sure that is 100 percent accurate, but that is a light tire!

    I just weighed the stock wheels and tires with no skewers, cassette, or rotors.The stock set -front and rear- weigh over 10.25 lbs. and around half of that is in the tires and tubes. With race tires (at the opposite end of the weight range) you can save 2lbs of bike weight with the stock wheelset.

    The stock Speed Disc rims are a good mid level, reasonably light set. The hubs are a little bit heavy but not excessively so. They are similar to a SRAM x7 hubset. I've wondered if there would be an advantage to sourcing some better bearings for them like ceramic or something.

    Since the overall wheelset weight is in the 2200+g area, it's really not terrible. Obviously about 1.5lbs can be lost, but we shouldn't sell the stock set short. It's a good entry-mid level set. The tires are heavy though

    I run a VeeRubber Speed-R Folding 29x2.4 on the front. Rated at 680 grams and very very noticeably lighter than the AKA's (as I would expect a folding bead to be.) Even a friend commented on it out of the blue when he was handling my front wheel.

    If the ignitors are 575 and work well set up tubeless, on a set of carbon wheels, that would be a very light front wheel.

    From what I've read and seen, almost all freehubs can use cassettes from both SRAM and Shimano since they are based on the same Hyperglide spline spacing. This is the current standard. So if they mention Shimano, SRAM would very likely fit.

    Shimano and SRAM are the same pattern. This "shimano call-out" is really a symptom from road bike sales where there are two cassette standards: Campagnolo and Shimano.

    SRAM follows Shimano's standard.

    Hope that helps,

    I'm waffling a bit but think even going with the Arch EX's I can save some weight. My stock wheels can have low-tread tires for road training/conditioning and then I can just swap to the Arch EX's and real tires for trails.

    Someone was spreading horror stories about the liability of customs mis-declarations falling on the recipient (me) with those Chinese wheels.

    Re: Weighed my black Goblin

    I have a set of arch ex's laced to hope pro 2 evo's on my goblin and there was a very noticeable difference right off the bat. I went tubeless with the original aka's and the difference from stock was incredible!

    But the bike really came alive when I put on some folding aka's (~700g) after the originals wore out....wow! For a total investment of less than $500, its definitely worth the money.

    Now this is what I want to hear! What were your thoughts on the AKAs tubeless on the Arch EX? I was considering just doing that and then getting better tires when they wore out. Granted, it's only another $100 or so for a set of nice Maxxis TLR tires...

    I ordered from these guys across the pond and have been very pleased

    http://www.cyclesportsuk.co.uk/wheel...t-p-13280.html

    They now have the new version of the hope hubs with 40t engagement...for $432 its a great deal. Also they sell a kit with stans sealant, tape and valve stems. British shops sell conti tires dirt cheap too so if you like them you can get wheels, tires, and a tubeless kit for about $550

    I love the aka's tubeless on the arch ex. I think they have plenty of traction but a bit of a learning curve....you really have to lean the bike into turns to get the most traction from the bigger side knobs.

    And actually if you get the arch's do NOT get tubeless ready tires! Theyre designed to be run tubeless with regular folding or wire bead tires. Tubeless ready tires are for wheels with UST bead hooks

    Sure does! I don't know about the tlr tire/stans rim problem from first hand experience, just horror stories from other people (mainly on mtbr)

    But my experience mounting regular tires was super easy, but you'll probably need an air compressor. I just put my bike in the back of my truck and used the one at the gas station

    Interesting. I (still) have a set of Bontrager Dusters (26") that I got the rim strips for and mounted Maxxis UST tires on them. I was able to get the beads to pop on the first try with a floor pump.

    Is it generally far harder to get non TR/UST tires to seat up properly?

    I mounted up a UST ardent exo on my flow ex without a problem. When I initially seated the tire there wasn't even any air coming out (I put sealant in anyways).

    Like I said, I don't have any first hand experience mounting tr tires, but have heard from many people that they're a major pain to mount. Especially the geax TNT tires

    I posted information to correct your misinformation about what Stan's rims are designed to run, not to debate user experiences you read about on the internetz. My first hand experience is that Specialized's line of 2Bliss tires mount beautifully to Stan's rims and can be mounted with a simple hand pump.

    ... and if we just ... Goblin complete teardown and weight

    Well, since we are getting hit with some pretty nasty weather I decided to tear the bike completely down and weigh everything since it was going to get a nice clean and once over.

    Hope this helps!! Obviously, these may not be 100 percent accurate due to scale differences, so don't hold it against me. I used my digital kitchen scale that measures to the gram, and all items are stock minus pedals and seat, as the seat was chucked last week from failure, YMMV.

    Weights and Measures
    Frame - 1872g
    Stock Stem - 138g
    Front QR Skewer - 56g
    Rear QR Skewer - 62g
    Rear Cast Derailleur Hanger- 13g
    Rear Hanger Screw - 2g
    Chain - 248g minus 2 links with Powerlink
    Bar End Caps (pair) - 4g
    Stock Bars - 339g
    Grips (pair) - 80g
    Seatpost and Hardware - 346g
    Seat (off my Giant) - 290g
    Seat Clamp - 30g
    22T Inner Chainring - 46g
    38T Outer Chainring - 77g
    All Crankbolts, nuts, and washers 2x10 - 31g
    Front Derailleur Assy. - 146g
    Front Derailleur Shifter, Housings, and Cable - 148g
    Non-Drive Side Crank Arm (includes cap) - 230g
    Drive Side Crank Arm and Shaft - 419g
    Star Nut and Bolt - 18g
    Stem Cap - 9g
    Crown Race - 14g
    Top Bearing - 21g
    Bottom Bearing - 34g
    Split Washer - 1g
    Upper Bearing Cap and Dust Shield - 11g
    Headset Spacers - 35g total
    - small - 5g each
    - large - 10g each
    Reba Shock - 1576
    BB with Dust Shields - 110g
    2.5 BB Shims (pair) - 4g
    Rear Derailleur - 246g
    Rear Derailleur Shifter, Housings, and Cable - 165g
    Front Brake Assy. with Brake Pads - 277g
    Rear Brake Assy. with Brake Pads - 297g
    Metallics (pair) - 22g
    Organics (pair) - 10g
    Geax AKA's (pair) - 1720g
    Front Wheel - 995g
    Rear Wheel - 1195
    Rim Strips (pair) - 51g
    Tubes Specialized 29er (pair) - 642g
    180mm painted CS2 - 150g
    160mm painted CS2 - 118g
    Rotor Hardware (12 bolts) - 24g
    Cassette Complete with Cap - 364g
    Cassette Broken Down:
    Shims x5 - 10g
    1-3 Assy. - 176g
    4th - 45g
    5th - 34g
    6th - 26g
    7th - 22g
    8th - 16g
    9th - 14g
    10th - 10g
    End Cap - 11g

    If my math is correct, here are my totals.

    12923g with pedals
    -117g after upgrades
    12805g or 28.23lbs
    -403g after 1x10 conversion
    12402g or 27.34lbs

    LOL! I guess I should pay more attention - use them as you see fit! It's cool to have a reference, especially when it comes to dropping big bucks on upgrades and weight loss. Makes me curious on what it is going to when I go tubeless this spring with the new rubber. Since the WTB wheelset is just over 2k, switching to lighter tires and going tubeless should be a big benefit vs. buying a lighter wheelset.

    My custom Arch EX wheelset with DT Swiss 350 hubs will be ready next weekend. Still need to figure out tires though.

    I'll definitely report weight though.
