Drop a few pounds

[KokoYeti]

My bike weighs in at 27lbs with pretty much stock components. XT RD, Truvative cranks, bontrager wheels, V-brakes. I want to get it down to around 24 lbs. What's it gonna take to get there? Wheelset, carbon cranks...?
Thanks in advance for any advice.

A Full list of the parts will help a lot in identifying what components are needed to be change to achieve the weight goal for your bike.

[jer]

a little more detail would help. A complete component listing perhaps? You may have a boat anchor for a stem that would be a good candidate for replacement but i can't tell because i don't know what you have. Also provide a rough budget. From you name I assume you have a Yeti Kokopelli?

Wheelset/tires is the best place to start IMO, then saddle, seatpost, and pedals.

Ah, you beat me yoko.

Ah, you beat me yoko.

I agree with jer, wheelset/tire is the best place to start !!!

[limas_mtb]

Wheelset/Tires/Tubes, I agree with you guys, but also maybe Seat & Seatpost, to lower the bike's CG

[KokoYeti]

Here's a list of parts to the best of my knowledge. yep it's a Kokopelli

XT Rear Der
Travitiv firex crankset (bottom bracket ?)
XT Cassette
Cane Creek headset
Bontrager wheels (not sure if hubs are)
Avid single dig 3 v-brakes
Deore shifters/levers
Titec handlebar
Continental tires with slime tubes
Gravity dropper seatpost ( I know, heavy, but it’ll be the last part to go because I like it)
Skareb shock (not the platinum)


thanks

Cliche of wheels/tyres/tubes will always be true. After that it depends on what you have already on the bike and your budget.

Cheap and cheerful are:

Alu bolts - (possible approx. 50g saving) levers, shifters, front and rear mech mounts / cable gripping bolts (front and rear mech) / I run discs but take a look around your V-brakes / adjustment screws in your mech

Titec Pork Rinds grips (possible 100g savings here alone!!!)

Carbon headset spacers

SLR Saddle (possible 150g + saving)

Maxxiss flyweight tubes 84g each 1.5 to 1.9 size
Others swear by Stans tubeless system - can run at lower tyre pressure too

Conti Twister supersonic tyres

Dura Ace 11-23 Cassette (144g saving - with chain more)
11-23 Cassette will also allow you to shorten your chain. Zero Cost weight savings

Bolt on Ti Skewers

Exlite seatpost clamp (stock clamps are approx 50g - Xlite only 12g (9g with Ti bolt)


After the above, you are re-morgaging the house, selling your sister into prostitution and living on beans on toast to fund an expensive habit!

Oh well, A man's gotta do what a man's gotta do.

Thanks for the info.

[KokoYeti]

Oh, what about cranks and bottom bracket. XTR? or Carbon, ?
The XTR is more expensive than some carbon cranksets. Is it lighter?

HI Couldnt help wondering about the tubes usede in your wheelset.
Drop the slime tubes, spec a pair of new cont supersonic and Eclipse Tubelesskit. Estimated weight reduction: 2lbs.or more.
and right were you'll need it.
Next thing to go could very well be the Truvative crankset. Take a look at a pair of new XTRs, or the FRM's yet to come. should give you enogh time to raise enough money
Do the wheel thing NOW... please and enjoy riding even more.

You were aiming for a 24lb bike = 10.9KG

My earlier suggestions should get the weight down to 25.5lb (11.6KG) and not blow too large a hole in the wallet.

Is your frame Hard tail or Full Suspension?
24lb on a HT wont bust the bank, or threaten your sisters reputation.
Are you planning to use the bike for Cross Country or Downhill?

As Far as cranks go, if would depend on your intended use. You are also looking at expensive kit. Your current crankset and BB approx weigh approx 900g. A top end BB and Crankset will cost you around $400 and weigh in at 600g.

For Carbon look at Storck Power Arms - they can chip though.
For Alloy have a look at Extralite Fish bones or Middleburn RS-8's.

[KokoYeti]

Wow, good information but sounds like I should strip the whole frame and start new. I expected as much. I might as well get a titanium hardtail frame while I'm at it.
Well back to reality for now atleast, what's a good, sturdy but light wheelset? I'll be riding a combination of crosscountry with some downhill. Not serious downs but rocky ones. Lot's of climbs. Lot's of cactus also. That's why I've been running slimes. A tubless kit should solve that one.

[gofarther]

Dude - lose the slime.

I contacted the manufacturer, and the tubes weigh 315-325 grams each!

Get a pair of Bontrager superlights / Panaracer Greenlites at approx 100g each.

$20 for 1 lb. !!! Cheapest weight reduction you'll ever do.

Good luck.

if your riding area is pretty rocky you may want to go with a wider tire than the supersonics and nokian nbx tires that a lot of us use. The Hutchinson airlights are respectably light and have a little more air volume.

I don't think that the firex crank arms are all that heavy, but the chainrings sure are. Get some higher quality chainrings (which will shift better too) and a lighter BB.
