;D Racers share your ideas how to reduce weight Dh race bike. or paano set up magaan na dh race bike using race proven parts magaan at matibay.
para madali itulak paakyat hehehehehe. ala chairlift dito.
1. fox DHX 400g lang, magaan din yung 5th with titanium coil spring
2. tioga cube 286 stem 255g yung 50mm.
3. Boxxers pa rin magaan dh race fork
4. easton components
5. mavic dh rims, 321, 521, 721. 729, etc
6. Ive seen road bike seat sample selle italia (cost much), bihira gamitin ang upuan sa dh run di ba? unless your going to tuck,
7. old XT 8 inch 6 bolt rotors
8. titanium bolts, hehehe world cup ba tayo sasali? hehehe

RD - shimano 105 or any short cage na rd for that matter TIRES - kujo's are, IMHO, the lightest dh tires around FRAME - syempre mas magaan ang bullit kesa sa shawn... CRANKS - Single plate na 40t sa harap Madami pa actually... Pero ang dabest na pagaangin ,and the cheapest, is the R I D E R....

i read this from mbaction a few months back:
Many bike techs actually remove 3 bolts from diskbrake rotors of pro riders to reduce weight when they race to save weight. (ano?) hehe maybe the rider doesnt know hehe

Other suggestions:
Primarily wheelset: use lighter tires & rims XT or XTR cassette. '05 XT cranks aluminum expander bolts & headset
;D

get xc tubes .. new wheelset .. xtr cranks .. how light do you want your bike to be??? 40 lbs is probably your target,for a DH bike?? if you wanna go for something in the mid 30's .. get a new frame?

i'm 135lbs. , i actually need the weight of the bike to carry more speed.
climbs on a DH run is not affected by the weight. it's proper shifting technique, tire selection and suspension setup that will get you through.
making a light DH bike nowadays is just another fad that companies started to be able to sell the latest and greatest, they always know someone out there wiliing to buy it ;D

(ano?) hehe maybe the rider doesnt know hehe hehehe, now that's sick. that would be scary. i wouldn't do that to my bike. but then again, there's always a first, hehehe. is it ok to use carbon fiber components on a DH bike? if it is ok, change the handle bar and seatpost to carbonfiber. is it ok to use DT swiss revos on DH wheelsets? if its ok, palit ka na din ng spokes to revos. how about using road saddles? ok ba yun sa DH bikes?

;D sub 40 lbs, 38 to 40 lbs pwede na.
*Truvative BoX guide is way lighter than MRP chain guide. Mura pa P1000.00 plus yung box guide with silent roller, remember to read instructions installing this one, para walang kawala yung chain, use locktight sa mga thread.
Nathan rennie is using one on his V10, race proven.
Also saw in the mag, Pro dh bikes, MRP with drilled Holes on the boomerang and the bash guard to reduce weight, looks cool may pattern yung mga holes hehehehe.
Now, who will do that on a P6,000.00 plus MRP chain guide hehehe, how about drilling holes on the frame hehehhehe? your ticket to the hospital.
*Thick POLYCARBONATE (PC plastic) Bash guards exsample truvativ. e13, over aluminum bash guards, weighs less, tapos transaparent pa, cool, kita yung chain ring mo.
* 32 holes over 36 holes rims? minus 4 na spokes X 2 gulong = 8 spokes hehehehe, malaki ba difference sa weight? may thread na ito somewhere.
* maxxis welter weight inner tubes.
* ;DBoxxer conversion kit, Trixx bike shop, look for nilo daep, fox technology, from sir nono.
*How about strip solution the frame to bare aluminum, hehehe ala lance armstrong, (local novice dher louie menia dehins na paint yung frame nya).
*For the rider, san mig light muna over pale pilsen, hehehehhe
->I think Lets stick to Aluminum, sa mga components katakot if you crash, Looks good in the outside but it could snap in to two the next time hehhehe
spacer, tapalodos, cguro pwede low stress parts.

have a rabid dog follow you down hill... ;D ;D but kidding aside, small component weight reduction will still not equal a frame that is lighter...plus the rider who does not have beer belly, instead has piston-like legs... component wieght-reduction I guess would be in the 1-3 pounds figures....while a lighter frame might be around 3-5 pounds lighter..... then of course there's the argument of dead-weight versus rotating weight..... lighter wheelsets suitable for DH will be a lot of help to a rig with a lot of dead weight. and of course a few visits to the gym will also help a lot, not just for pushing the bike uphill, but also contribute to better bike handling, since you can "manhandle" your heavy DH bike.....

Use of Carbon fiber components on high impact parts is still debatable, some say yes (scott, easton, fsa, sram), some say no (race face).
shimano? <-abangan.
Think of manitou's race proven world cup level dorado downhill fork, with carbon fiber uppers, saludo ako sa mga nag design nito.
by the way some one is selling a used dorado sa PCN yahoo groups.
but then again, kung kasing taas na ng bahay na ang drop, aluminum pa rin.

i think dorado's can do anything. cedric used dorado's with carbonfiber upper legs to win the redbll rampage in 03 right? but other than that, i tnink aluminum na all the way. -(i saw an xc rider in MBA with a snapped carbonfiber seatpost in the middle of the trail. he had to stand up the rest of the way ithink.)

may i add something regarding the RD set-up ;D
shimano 105 is good, but quite pricey for me hehehe, so i instead used the shimano Sora which is 2x cheaper than the 105.
i agree with the carbon fiber thing, still durable, perhaps only if you're on a track na puro roll and minimal jumps/hucks. aluminum is still best ;D

yea .. exactly .. my bike weighs 40 lbs and im pretty happy with it .. if i get a new fork (boxxer/ fox 40) and change my cranks ,the weight will probably go down to around 38-ish pa .. i've tried riding joey b's bike and i can easily feel the difference. he's got a really light bike,man. it was easier to throw around and sprints really well. it had a good balance. i really felt comfortable on his bike so i realized that his set up is perfect for me too. ;D its just that im not used to copying specs from other riders. does anyone have this mentality too?

If it helps you win, why not?
Joey B's bike is still a tad heavy, look at his size, the goal before the end of the year is to drop 2 to 3 pounds more.
As always, PM for questions ;D

I'm not a DH guy but Isn't that DH bikes were designed to be heavy? The heavier the faster going downhill???

I'm not a DH guy but Isn't that DH bikes were designed to be heavy? The heavier the faster going downhill??? a DH bike also has to be maneuverable at high speeds.or even at low. if the bike is heavy for the rider,the rider will have a very hard time going down a race course. keep in my mind that not all courses go all the way down. you need to pedal more in other courses and having a lighter bike is an advantage. i cant put my thoughts together but i hope you got my point.ü 2 to 3? joey's gonna love that .. sucks to be me! hahaha! ;D hows your bike doing so far? doing good?

ummm.... listen to quiesledaddy (Nono).......... he knows what he's talkin bout.... why try to build a sub 40 pounder DH rig ...myt as well build an AM rig.... and keep the DH rig at 50 lbs..as it should be.... Stupid poser mentality..... nyahahahahhaha... its not what u put in your ride.. its how u actually ride is what matters.... iv seen topshelf bikes get beaten down by mall bikes... WHY? lolx!
for example: 150k bike + poser rider .......will never ever beat..... 20k bike + skilled rider
tama ba nono?

sorry,tao lang. FYI, joey's bike is at sub 40.and i really dont think they have that "stupid poser mentality". i wanna progress,man. so if sam hill,peaty and those other FAST guys/girls in the WC circuit have this "stupid poser mentality",then im in.
my point: 150k bike + sam hill .......will MOST PROBABLY beat..... 20k bike + steve peat.
