My first attempt to shave weight, lost 4 lbs!

Been reading and posting in the weenies section for a little bit and figured I would give it a shot since I am not riding during the winter and I had some extra money.
Slapped on the following:
Race Face Turbine, 2 + BBG bash guard.
XT front and rear derailleurs
Race X Lite bars and XR stem.
Lost near 4 pounds from the stock components: steel bars, beefy stem, mammoth crankset...

check my blog for further info/pics.

Any ideas to loose some more would be great!
Probably a wheel set would be a good idea.

well... 4 pounds is a lot. that is pretty hard to believe - 2 lbs ok, but 4?

what parts were on before?
Everything on before was stock.
Truvaiv X-flow, all steel, one piece, the thing was riveted, didn't even have chain ring bolts, and the original square taper, replaced the BB with an ISIS, almost 1/4 the weight.
Bar was steel, stem was 7071, the bar and stem alone was 1.5 pounds before.
Derailleurs probably didnt save much, but the rear lost around 125 grams, the front around 30g.
Maybe 3.5, but I still think its closer to 4, last time it was weighed it was over 30 lbs.
An accurate scale is a must. It's a crapshoot at best if you rely on manufacturer's claimed weights. Some are accurate; most are not. This forum is a great source of information if you search/ask. ;)
I had a front wheel + tire on my old bike that weighed 10 pounds. When you have components like that losing weight is cheap and easy.

(It was a sun singletrack rim with a >3" tire) Totally ridiculous for what I would use it for, but that is how I got the bike.
I believe it. I found an abused bike sitting by the garbage at the university. It was 18" Aluminum and started out at 28lbs...I replaced everything on it with parts like octalink crankset and aluminum handlebar and seatpost and turned it into a 1x8 and I lost nearly 5lbs. The tires alone weighed 900g a piece!!

It's not worth posting because it's a crappy frame, but it's light and I'm not afraid to lock it up anywhere. Y'know people always wonder why it's worth being a weight weenie, but when you have to lug a bike up a couple flights of stairs a few times a day, dropping 5lbs is a huge difference. It makes opening doors easier too, because I can now carry the bike with one hand.
I would get a lighter:
Post: Thomson
Seat: Toupe
Stem: FSA or Origin8 OS(light and cheap)
Carbon Bar: Easton or Origin8

That would drop some weight and you will not go broke.

Congratulations! Always nice to lose that much weight at once, but from here on in it gets tougher and tougher. :)

Checked your blog, and don't see a specific parts list, so just going off of the photos, I've got a couple ideas.

  • If the parts you had were that heavy, you can probably save quite a bit of weight with different wheels! Don't know the specs on the wheels in the pic, so can't say for sure.
  • Lighter seatpost
  • Can't tell how many speeds you've got, 8 or 9, if it's 9, you can save a significant amount of weight by going with a Shimano XT cassette or the SRAM PG-990. I have the 11-34 SRAM that weighs in at 300g, an 11-32 is even lighter. The SRAM also comes with a bling-tacluar red alloy lockring.
  • If the cranks and such were that heavy, the saddle's probably pretty heavy as well. Something with Ti rails could save you quite a bit.
  • Looks like a 180mm front disk? Get a different converter for your front brake and switch to a smaller disk, that'll save some weight.
  • While you're switching brake disks, the Alligator serrated brake discs will probably save a bit of weight over what you've got now and are pretty cheap.
  • The brakes themselves are probably on the heavy side, but new lightweight disk brakes can be way pricey.

Good luck!

I still run 8 speed, so higher end parts are somewhat limited, but from time to time items come up on ebay.

What wheel sets would everyone suggest for someone on a budget?

You can get Sun EQ21's on XTR hubs with DT Revolution's on CRC for pretty cheap. Should be 375-ish. I know with Hopes it's $310 or so, free shipping.

If your rear hub takes an 8-speed cassette, it'll also take a 9-speed cassette, so you could replace your rear shifter with a 9-speed shifter and then move up to an XT 11-32 9-speed cassette, which is lighter than your 8-speed all-steel one. If your old chain has lots of wear, then you'll want a new chain at the same time.

Light tires and extra-light tubes are another way to cut weight. I tried some of the Continental Race King Supersonic 2.2s with ~120-gram tubes and really like them for general XC-style riding, that's one good one to consider. Figure about $100 for that.

Based on the good remarks about ESI's grips, I also tried some Racer's Edge grips, which are about 50 grams, versus about 90 grams for my conventional rubber grips. I like those too, and they're an affordable upgrade. No throttling, either.
