    29.6lbs and erm nope sorry. :lol:

    i was guessing it to be a bit lighter, not really fussed but just curious.

    weighed my bros std marin wolf ridge and thats was a hefty 36lb.

    Seems about right to me. Some of those parts are definite cruiserweights.
  • richg1979richg1979 Posts: 1,087
    ye i know the hoops/tyres and m4s aint no light weights.

    I'd be surprised if many quoted weights were for large frames, not sure how that factors in.
  • Most quoted bike weights are for mediums.
  • The quoted weight for a Charge Spoon saddle, with Ti rails is 240g-

    I weighed mine and it came in at.......... 239g :shock: :shock: :shock: :lol:

    1 gram? I'd have them for that ;-)

    But it is true, most quoted weights are on the very optimistic end, lightest sample, smallest size etc.

    Most quoted bike weights are complete nonsense.

    there fixed that for you :wink:

    therre was a time when some manufacturers (notably cannondale, but there may have been others) publicly refused to publish claimed weights citing the tendency to underquote by upto 30%. They said they'd be forced to lie in order to appear competitive next to claims made by others. Anyone who's ridden a cannondale HT will know that heavy is one thing they are not.

    As for your (OP) initial guess of 28lbs and final of a hair under 30, you're within 6% I'd be pretty happy about that.

    My Ibis Mojo frame is claimed to be 1350g. In fact it's 1500 (medium) so even the small guys are at it.

    hit up weight weenies if you want to see where this obsession can lead.....

    If riding an XC race bike is like touching the trail,
    then riding a rigid singlespeed is like licking it
    ... or being punched by it, depending on the day

    Cannondale were on to something, it only takes one to start bending the truth and everyone has to follow suit.

    I'm not that bothered about weight anymore, well rotational weight I pay attention to when I spec things, but otherwise, it doesn't make a heap of difference IMHO.

    In the words of Boris the blade: Heavy is reliable, I always go for reliability.

    My Cove comes in at a mighty 44lbs. So it was well worth the extra £300 for Ti Forks springs!!! Not.

    P-Jay I'm with you to an extent, however the first time I pulled up on the bars of a sub 20lbs singlespeed popping up some steps and inadvertently threw the whole thing backwards over my shoulders I thought "I could be onto something here". Hence I have bikes that weigh in at 18lbs (ish), 30lbs and 40+. Horses for courses although I think that all up 30lbs is a good honest weight for a bike

    Bike weights are always a bit on the dodgy side.

    Really unless you've got a carbon dream machine anything with 5" to 6" of travel is going to do really well to get under 27lbs in a Medium machine.

    Once you add real world tyres (not silly light things) and pedals you start getting realistic weights. Most pedals you're looking at a minimum of 400g's for the pair.

    you can go over the top with weight watching.
    I tend to look less at the weight nowadays and more at the stability. However I used to be a little obsessed with it - changing all my nuts and bolts to aluminum to save some weight.
    My mate discovered a funny one though. He's got a Trek carbon Fuel built with all manner of crazy light parts. He tried to get his wife into biking and bought her the cheaper Trek and built it from the frame up - he was gutted to find out that her bike was actually lighter than his...

    I like the way manufacturers give the weight without pedals - 12,5kg for my bike apparently - stick some pedals on and some decent tyres and you're already way over 13kgs...

  • My personal favourite is my single speed road bike, steel frame and forks, but when people will ally geared roadie pick it up they're amazed... It usually weighs about the same!

    Same goes for my inbred, scary light!
  • adb1006adb1006 Posts: 938
    How much does your inbred weigh?
  • I must confess,to weight weenie tendencies I have weighed all the components on my bike.

    In my experience,Shimano are fairly accurate,Schwalbe tyres scarily accurate,if not lighter than claimed,yet saddles,built up wheels and frames always inevitably weigh more than quoted or expected

    Same here :oops: I've weighed a lot of bits on mine. Everything i've weighed has been lighter or bang on what was claimed. I think i'm using a fairly accurate scale as well as it's a fooking expensive franking machine! Only problem i have is that the scale is at work, so i have to take bits off the bike, and bring them to work to weigh - gets you a few strange looks (especially when taking a photo of a part on the scales!) :lol:

    Total weight is always more than the sum of the bits - cables and hoses are never added on to the weight of systems, and neither is grease that is used. Plus manufacturers weigh without pedals....
  • It`s surprising how the little bits add up,isn`t it?
    Cables can be 100g,hoses another 100g,even my XTR spds are 325g.
    Then there`s the little accessories like bottle cages,computers,pump/light brackets that people forget about.Could well be another 100-200g there.
    Anywhere between 1.5-2lbs that you could miss.......

    I've weighed all my cables and hoses :oops: Well, they were attached to my shifters/brakes when i weighed them :wink:

    Haven't bothered with grease though!
  • _Ferret__Ferret_ Posts: 660
    I think when you start weighing the grease on your bike it's time for the mental home...
