How to make my bike lighter
 
Hey, i currently own an S-works HT, the problem is it weighs way more than it could... its got alot of potential, i just need to know what parts to switch, that would give me the most weight savings, for a reasnoble cost. It currently weighs a fraction over 25lbs, and i wanna bring it down to about 22. So help me guys, what parts need to go first? I weigh 145-150, so the parts don't need to be heavy rider resistant :)

Specs:

Frame: S-Works HT 2004
Fork: Sid Team 2004
Headset: Cane Creek Aheadset sp-3
Brakes: Shimano Deore Hydraulic Disk 525, with Shimano XT Rotors
Cranks: Specialized Strongarm 2 (Square taper)
Bottom Bracket: Wheels: Shimano BB-UN-52 (Square taper)
Pedals: Egg Beater S
Cassette: Shimano XT
R. Derailleur: Shimano XT
F. Derailleur: Shimano XT
Shifters: Shimano Deore (with indicators installed)
Handlebar: Epx Carbon Flatbar
Stem: Thomson Elite
Seatpost:Thomson Elite
Seat: Specialized Body Geo Pro
Wheels: Mavic Crossroc Disk (UST Tubeless)
F. Tire: Michelin Front S (UST Tubeless)
R. Tire: Michelin XLS (UST Tubeless)

Maybe some insight in to what is carrying most of this weight? maybe the cranks?

Anyway thanks for any advice and insight

If I had a guess at where the weight is, I'd say, suppesion system, frame, etc. Its a mountian bike, not a roadie is there a reason you are trying to lighten your load?

25lb's! and its a hardtail, are you sure your scales are working, is this the same s-work we are tlaking aobut here, my sumpjumpper weights less then that, you have very light forks and the say componenets as my (xt) so its either the wheels or the frame that is making it heavy, try getting lighter wheels i dont know how much the ones you have weigh but i would have thought the frame must be lighter then my frame if its an s-works, wait a second what size frame do you use mine is 17 inch if yours is 22inch that could explain a lot!

Just get a more optimistic scale... Problem solved! Can I have any of those parts you decide to upgrade?

Pull off the reflectors!

well, it was weighed on a professional bike scale (one of the hangy ones)

I think it must be the cranks (with bb) because they are off my old bike and sort of deore quality. The only other thing i can think of is maybe the brakes, or the wheels. but i dunno what a good alternative would be that wouldn't put hole in my wallet. I was thinking of getting xt cranks (ones with integrated bb), what are peoples experiences with these? are their any lighter, just as stiff alternatives in the same price range?

as for why i want to make it lighter, i race alot of xc, and a lighter bike is 1) easier to climb, 2) easier to manuver around in technical sections, 3) easier to accelerate once over obstacles etc... and im sure their are endless others.

my frame weigh's a smidgen under 3lbs, 2.9lbs (anodized silver 2004 S-works Hardtail frame)... its a 19 inch frame

Thats odd, i would have thought that bike would be lighter than 25lbs. mines at 22 and my frame weighs the same as yours.
for cranks I am using Truvativ Stylo Teams, non GXP. Cambria bike sells them for 99.95.
Look at the reviews on these things, they are excellent cranks and i think they weigh in at around 600grams. I think they are pretty stiff myself. And as for a BB look at the FSA platinum Pro, its a good BB. If you want lighter you can look at ISIS bb's with a carbon shell and titanium spindle

i just checked the weight of my wheels, and the set weighs in at 2.3lbs (without tires or cassette)

toomyus 08-08-05 11:12 AM

i dunno dude, i think your scales is wrong too because my dad has a 17 04 stumpy comp and it ways 24 even and ve a 04 stumpy comp with disc and it weights bout 26.2 and its an 18. so i think ur bike is more likely 24 or so. if you want a lighter bike,then change your bars, rims and seat and post. but you sacrifice what a mountain bike is for. lighter wheels will buckle faster, your bike wont take as much abuse. so there is a balance there. anyways good luck

The bars are already about as light as bars go 125grams, the seat... well the most weight i could save with that can't be more than 40 grams by switching to an slr (and i can only ride road on an slr), the post is a thomson elite... (very light and very strong)...

is their some kind of hidden weight or something on my bike that im missing :eek:

Replace your fork with a rigid fork and turn your rig into a SS. You'll save more than the three you're looking for....and you even get to keep your discs!

AndrewP 08-08-05 01:54 PM

Get rid of the disc brakes and replace with V brakes.

Calimoxo2 08-08-05 02:22 PM

If you wanted to ruin your seatpost you could cut off what you don't need, just leave enough left over as indicated by the "max ext." mark....

Easiest way to "make the bike lighter?" - Make the rider lighter!

Sigurdd50 08-08-05 03:27 PM

Get a drill and a few metal bits and start drilling holes
the you want to see DAYLIGHT thru them components!

Lots of holes

more holes

Yeah given what you've said already with your other components that are already really light, I think you might try swapping from Deore discs to avid mechanical ones, although you might lose a little stopping power. But I think they should be lighter.

Don't think you're gonna be dropping 3 pounds off your weight by switching though, I can't understand why a Sworks HT would weight 25 with those components that you mentioned.

not really the same thing, its easier to maneuver a light bike, easier to accelerate over climbs etc...

im also 9% fat, and weigh ~147lbs, so theirs not much weight to be dropped

Hear hear! But scrap the disks and put some V-brakes on - even cheap ones can be less than 400g per end (with levers, calipers and pads).

Resurrecting a 3.5yr old thread?

OP could be deceased by now ;)

Panthers007 06-09-09 12:25 PM

Don't have a second donut at breakfast.

diamandgeezer 06-16-09 12:24 PM

Duh!
 
Sorry - I'm new, and forgot to check the dates :eek:

At least I won't do it again.

Has the OP found out where the "extra" weight was? I came across this thread searching for opinions on drilling holes in parts to make them lighter (in my case, the crankset).

No. The person who should be apologizing is the one that complained about how old the thread is, not you. People who reply to an old thread rather than starting a new one should be thanked, not chastised. I know this comment is not adding to the original thread topic but it's too important not to be said.

given the OP way back then ['05] was talking about a Mountain bike,
with a suspension fork. the lighter bike answer is ..

N+ 1, .. buying a lighter non mountain bike .. it's just money, after all ..

for the UCI pro races there is a minimum weight, now surpassed,
but never a maximum on money spent to go below that,
carbon fiber and titanium, and light aluminum alloys..
then add a few grams to come back up to it.
which is the current situation.
in road and cyclocross racing bikes..

The OP was 20 years old when the first post was made. He's now 118. So probably dead.
