Any weight info for the Howitzer setup? The spec sheet on the truvativ website does not show any.

...when SRAM originally updated the Truvativ website, they posted some pdf.'s with ALL of the crank and BB weights, including the new Howitzer. Then, mysteriously those PDF's disappeared and were replaced by new spec sheets that had the parts weights either deleted or replaced with N/A...

I have copies of the original spec sheets and according to them, the Howitzer BB is 365g.

Main things to change are the wheels for sure.
823s on I9 and a Gamut P40 also.
But really you could spend 2000$ and the bike feels the same.
Dont go crazy and spend the extra money on uplift,races.

 

[Secret Squirrel]

Hmmm....then maybe the How/Hol setup is closer to a kilo than I thought....Ah well....it works for my pig!!

 

[Bicyclist]

Get a Gamut P40 guide, Altas or Middleburn cranks, and lighter wheels.

Stem and bar would shave a bit too. Otherwise it looks good.

 

[Bicyclist]

The coolest thing is that Middleburns are expressely warrantied against DH, jumping, racing, etc... Not to mention they're light as hell...

Too bad that warranty doesn't include splines, tapers, or threads. So basically if you snap the middle of the arm it's warrantied.

 

[sharkdh]

those DT rims are a joke!
Yeah they roll really fast but one run and it was flatspotted like crazy.

I didnt flat though.....

thats exactly what i was thinking, not a whole lot is covered, the stuff you actually mess up is not covered

 

[Bicyclist]

That said I think they're good cranks but people push the warranty as a major selling point even though it's a joke.

An LG1 guide is 60 grams lighter than any other guide on the market, and he could just get a conversion kit for short $$ from his SRS if he wanted. I am with you, work on the stuff that will make a difference and not compromise the performance of the bike, and spend the rest riding and having fun with the bike. Any bike between 39-45 lbs is going to be awesome. You dont need a sub-40 bike to tear it up.

[sickbullit]

In addition to the cranks/wheels you can shave a pretty good amount by getting rid of the PC 970 cassette and going with a 9 speed road cassette...if you want ultra bling go with dura ace, but i got a 11-23 Ultegra (cost around 40 on ebay), and it is WAY lighter than the 970 i was running before...not sure how much lighter but significant.

 

[ffonsok]

you should have put on a dorado like your brother did
*joking*
but fox 40>world cup

 

[jake133]

At less you have a ton of money, or race at a pro level, i dont see the point of replaceing perfectly good parts just to save some grams.

 

[Superdeft]

I'm trying to bring the weight of my 43lb M3 down too, but I think the only area I could save any reasonable weight without spending much are my crank arms from ISIS v-drives to Gravity Lites as shown. I bet my tubes are heavy too.

Any ideas for shaving weight for cheap?

he races semi-pro. . .

 

[SteezyWeezy]

take the brakes off, nobody uses them in the hood anyway

 

[downhillracer]

jake 133- at a highly competitive level of racing you need a highly competitive bike. i don't spend my money i earn at work on crap, i save for my bike.

yah tubes are heavy, but i went to tubeless for a while and had way too many problems, now i ride tubes, i may go back to tubeless, but only if the technology improves on the tires. as far as cranks i kinda like those new holzfeller octs. sounds like a decent crank. anyways since i started this thread i've got some deemax wheels, and 07 internals in my fork and a couple other little things, ditched the X.0 and hollow pin chain, not reliable. my bike is now 42lbs. i am happy with it.

 

[SteezyWeezy]

get xt cranks, the octs dont end up being that light with the howitzer, but still lighter than your exsting cranks

 

[CRoss]

ditched the X.0 and hollow pin chain,

I have been running the same hollow pin and drilled plate chain for 3 years(too lazy to replace my drivetrain). I honestly can't believe it is still working. The chain has held up through all kinds of abuse, a ton of DH, and a lot of climbing on the DH bike. Most the ways I have seen a chain fail, having a hollow pin would not make it more prone to failure. Having the drilled plate concerned me but I am not torquing a chain like I did when I rode trials.

 

[dhkid]

thats weird, aren't m3s a hair lighter then v10s? which are 11.5 ish lbs, which is maybe .5lbs heavier then my commencal frame. i got mine down to 41 with out any silly light parts... could make it sub 40 easy..

 

[mattmatt86]

Im about to replace my seat, post, pedals and stem and I calculated that it will shave 1.24 lbs. I have a stans No tubes kit, but i cannot get it to inflate, I might take it to the LBS and let them try. Anyone know how much an IRC 2.1-2.5 tube weighs? Im hoping to lose another lb between the two tubes.

 

[ridea]

id go, Ti kit
single tracks (with no tubes kit) or mavic usts
no bigger than 2.5's and maxxis (unless its real rocky then a 2.7 front)
i was looking into hubs and im pretty sure proII's are the lightest avaliable if there not its only a few grams in it and id bet you there more affordable anyway. and some lighter spokes
ibeam(you didnt mention seat) im not sure on the weight of your post but i its lighter than an ibeam then get a sel italia slr seat.(just make sure its cut down, dont go to the lengths of drilling it tat will make fkall difference.
If theres allot of ecess material on your bash then lathe that
bar and stem wise, e-13 may save alittle but the bolt on setup will be lighter than a bolt on stem because of the sterer.
bar will only be about 25g
shock wise, i wouldnt do it, its a big sacrifice in proformance and tbh theres probably not a huge difference between that and a ti dhx
cranks, xt or atlas will be the biggest saving, also middleburns wil be a big save, the first two sacrifice strength but some guys get away with it, the later will sacrifice in durability that is untill somone comes up with an external bb set up for isis cranks thats compatibal with all cranks. hozfeller isnt a huge saving realy so its prbably not worth your hard earned cash.if you cant see saving more that 1.5-2lbs then its probably not worht doing, tubeless is deffinately worth a go though

 

[al-irl]

xt cranks
mavic 721s with pro 2 hubs.
E13 LG1

Those 3 things will make the biggest difference and defenitly the most cost effective way of lightening up your bike. Anything else is just gonna be about shaving grams here and there and make not much noticeable difference.

 

[dhkid]

721's pro2 and compettition spokes, maybe alu nipples, they dont cost more....

the lg1 doesn't save that much weight... maybe 50 grams?

 

[TheInedibleHulk]

why is this thread alive again??

 

[al-irl]

the lg1 doesn't save that much weight... maybe 50 grams?

Its a fairly noticeable difference from an srs

 

[dhkid]

i did mean srs, but then again the srs is pretty danm light, the whole thing is under a pound.

 

[dw]

LG1 weighs 195 grams, or 0.43 lbs.

Superdeft, I noticed in the build listed you showed a 32T ring. That's pretty small for DH use, even with a road cassette. Heck, 34T is pushing it. At whistler I can spin out a 34T all over the place. You may want to consider a 36T. Just a suggestion.

Good luck and have fun!

Dave

 

[bElliott]

intense tires are beasts

also how are the bombshells? for strenghth

 

[dhkid]

forgot to add, if you are running a lg1 i would assume you would run the taco also...

 

[Bernard]

This the way I set my M3 up... The weight is a stunning 17.1 kg... don't know how much pound that is... (I believe under 38 pounds)

I'll change the tires when racing by switching to full on tubeless downhill tires, adding 1 pound together.

Some things which I consider changing are:
Seatpost --> thomson elite, because the setback isn't needed
Spring --> Using a Ti-spring, will save some wheight
Cranks --> they're light but f*cking ugly
E13 bashring --> a black one for better looks

37.7 pounds.

Nice bike, wish I had one, and lived where it would work.

Are those Hope Mono Mini brakes?
got a spreadsheet of your build and real weights?

 

[dhkid]

i was wondering too, looks like juicys with m4 rotors.

isn't your shox upside down?

 

[Bernard]

somehow I knew this question was comming....

Juicy ultimate brakelevers, lightened with alu bolts
Juicy 7 calipers, lightened with titanium bolts
225 hope front rotor, 200 hope rear rotor making a light but powerfull system

Shock isn't in upsite down, this is a 06 frame which doesn't have the new upper swinglink (with is milled out, where the shocks comes by)

 

[dhkid]

is the contact surface of the rotors sufficeint for the juicy pads? i am thinking about getting some floating rotors for my jucies too, should save quite a bit from my galfers.

 

[Bernard]

Well, would not really want to recommend it for every one. But it works for me.
Friend of my used a simular setup last year, delivering lot's of brake power and it held up pretty well. But I don't know how fast it wears if you're riding races every weekend...

 

[dhkid]

what i mean is the the rotor contact area deep enough to that the whole of the juicy pad has contact with the rotor.

No you'll use some of the "splines" (the internal spider)
