why my rockhopper is so heavy?

hi, as i just posted, i bought a new rockhopper 05, its an XL so i compare it to my old bike, a gary fisher wahoo made of Cro-Mo and they weigh the same... for me its ok... the only explanation is that the GF is medium size but its not a very heavy bike... and i tried mi uncle's bike a giant iguana and its weigh rock! i think the aluxx alloy is great.. very light altough its a large i believe... maybe medium... but i don't understand... does that happen due to a huge frame (21 inches)?

WOW a 21 inch frame lol i dunno prolly I wish my briser came in a bigger frame other than my 16.5...im 6'3 lol and that doesnt really go too great...but my briser is really heavy for a 16.5, like my 4300 is so lite and its the same size too.

A larger frame will defintely weigh more than a smaller frame. And it will also depend on the component choices on the two bikes. But if your RH doesn't feel heavy when you ride it, don't worry about it!

How much does it weigh?

My 23" Rockhopper Comp with XT/XTR goodies, CF Monkeylite bar, Thomson seatpost, Avid Single Digit Ti brakes and levers, Mavic Crossland wheels, and Marzocchi Comp fork comes in at 26 lbs. I'm quite happy with that for a 23" frame.

My smaller 21" 'Hopper frame actually weighs more at 29 lbs. with heavier-duty componentry however.

The size of the frame will have some effect on the weight, but not nearly the biggest effect. The weight of the components is a much bigger deal. For example, on my Trek 4500, the frame weighs somewhere around 4-5 pounds. The total weight of the bike is 32 pounds. In other words, most of the weight is the components, and small increases in each component add up when everything is bolted on.

On my bike, I could save over a pound by replacing my stock Judy fork (something I've considered doing for a while) for something nicer. I could save at least 2 pounds with a better wheelset. There's probably close to a pound of difference between my Alivio drivetrain and XT gear with a lighter chain. I really don't know how much I could save by changing out my seat, seatpost, handlebars and stem for more expensive parts, but it should be possible to build my bike to 25 pounds without resorting to extreme measures.

I think it is the more butch components. My now rigid diamondback sorento has steel handlebars and low end everything else and it feels like twenty pounds with my surley fork, compared to my '05 rockhopper which feels like 32 but rides fine for me. Personally i am fine with it, considering how I am abusing it I figure it might last longer.

By the time you do all that you can build another bike!

Actually I meant going so far as to shell out for XTR components, SID Race, Salsa skewers, etc...far more damaging to my wallet than any cutting implement

I've seen Salsa scandium hardtails (the frame weighs like 2.5 lbs) that the owner claimed weighed 19 pounds built up, but they spent as much as $5,000 on the setup.

work on reducing weight on the extremities of the bike, like the wheels/tires. You will feel a much bigger difference than starting with the frame. Of course unless you buy a stupide light one that I doubt anyone makes anymore.

Oh no B, You be careful the freakin' cyber police have had an itchy trigger finger. Can't joke around you might hurt someones feelings. Gotta be real PC.Not the mods that normaly hang here but some others have been riding their corn cobb seat. Having said that, mine comes in a 34.If your not racing its just a better workout.

Sounds like overkill to me, I'll stick with my 39 lb hog.

I got my Trek 4600 down to 23 pounds. There is no suspension or gears, hence no big or granny chainring, no oil resevoirs, no shifters, half the cables, and 8 cogs out of the cassette. The Judy weighed 6 pounds, and the 1x1 weighs 2, so doing that lopped 4 pounds off of the bike. I wasn't trying to lighten the bike, it is just a nice side effect.
