I went from fs bike to hardtail because i want a lighter and faster bike. I bought a trek 8500 frame size 17.5 and transferred the parts from my heckler to it. the build is finished and now my bike weighs 27.5 lbs. I still want it lighter so i wonder which part of my bike is causing this weight.


frame trek 8500 size 17.5
fork 2003 Marzocchi MX comp coil
tires: specialized roll-x
rim: mavic X618
hubs: specialized stout
crankset: shimano Hone
stem and handlbar: Easton A70
saddle: WTB Rocket V
seatpost: generic alloy
brakes: Avid mechanical disc
brake levers: Avid
shifter + rear der: sram x.0
front der: shimano xt
pedals: shimano M647
headset: chris King

Can anyone suggest at most two parts of the bike where I can gain the most weight saving? thanks

The fork, but some people a are willing to not save weight there to have a Zorky, but definitely the BRAKES... get some light hydraulics like martas and save at least a pound, with better performance

Those pedals are pretty heavy. Some stainless eggbeates would save over 300g. My guess is that the seatpost also weighs a bit, so you might be able to save a few good grams there in the future. Many recommend foam grips (I love them), bolt on skewers, and lighter tubes and tires for a cheap start. I'd say keep your tires since they handle very well in my opinion, but go ahead with the other cheap upgrades (count those as one thing) and the pedals.

I would think the fork.

How are the hone crankset and the pedals? I want those, and want to know how they perform, I'm not that worried about weight.

In building a light bike, the extra weight comes from everywhere. Ryan123 is right, a few extra grams here and there really adds up. I bet the most weight is in the Hone crankset and the fork, so if you only had to pick two, that's my bet. But if you want light, don't stop there. The order I would change things on your bike would be: Cranks/BB, fork, wheels, tubes, tires, brakes, pedals, seatpost, stem, seat, handlebar, cassette, shifters/derailleurs, bottlecage, grips, bolts.

The 8500 can be made into a respectably light racing machine. You can use my buildlist as an example, coming in at under 20 lbs.

Most bang for the buck?

Switch out pedals for eggbeaters.

Seatpost for thomson.

Saddle for something light like a selle italia flite TT, or whatever.

Brakes for something light like martas or hope minis.


Those could save you about about 2 pounds, that would get you on your way pretty fast.

We built a 29lb hardtail at the bikeshop last week for someone that wants to ride pretty agressively, rhinolite rims and deore hubs, 2.3" freeride tires, etc. That weight adds up real fast.

i think you should invest on a nice set of wheels. something like xtr or dt 240s hubs, dt rims and wheelsmith double butted spokes. that will be light, not that expensive and very reliable. and dont forget to get light tires and tubes too.

than look for some foam grips like ritchey wcs or titec pork rinds, race face deus crankset, eggbeaters pedals if you want lightness or shimano m540 if you want a trouble free pedal, thomson post, slr or flite tt sadle.... and keep going :D

not going to save much weight, maybe 100g TOTAL for rims, then about 40g total for butted spokes, about 40g total for the alloy nipples, and the rest will be in the hubs, but this is going to cost up the wazoo and he could use that money to change out a lot of other things and save much more weight.

Wheels and tires is one of the areas you look at to save weight, but this guy actually has a bunch of other areas that can easily drop weight before even looking to the wheels.

Reba or Marathon SL fork: -400g or so
Marta SL brakes: -300g
240s hubs: could be -300g, hard to say with OEM hubs
M540 pedals: -200g (eggs cut more)
Twister Pro tires: -200g or so
butted spokes: could be -150g if yours are straight
Thomson post: could be -100g
inner tubes: could be -100g
handlebar: flatbar could be -100g
and low-end cassettes can be heavy

wow! that's under 20lbs! fantastic. nice bike you have there. btw, what is your height? Im 5' 11.5" but I chose to get a 17.5 size trek 8500 because i really want a sloping top tube and also because I am okay with the 23.1 top tube of size 17.5

i changed the fork

hi guys, thanks so much for all your nice suggestions. I was able to sell the MX comp fork and replaced it with a slightly used Manitou Skareb Elite and I am having a significant weight loss in my bike, its playing around 25 lbs. I just hope my weigh scale is accurate :D i know, i can lose some more weight in other areas but i leave that some other days. As for now, i am quite satisfied with it. ;)

Glad to hear! Soon enough, you will be hooked and that 25 lbs will keep going down given enough time. You should notice a considerable difference taking 2.5lbs off the front end. Welcome to the club. :D

I weigh 155-ish, 5' 10.5" and think 19.5" would be too big. I like the compactness of the 17.5", easier to flick around. THe bike is actually my fiance's bike I built for her, but I like taking it out once in a while when she's not looking. :D
