Orvan you have to tell us some more about the new wheels. I see they are TUEBLESS can't believe there is finally an alternative to Mavic 823 and they are a little lighter complete than the 2009 DeeMax. Do they sell rim only?

:clue: Tubeless with a rim strip, or? So no real alternative to a 823.

As far as I can see there are no holes in the rim and the tech sheet says no rim strip needed.
But how do you get the spokes/nipples in? I don't see anything like the FORE stuff Mavic uses. Maybe like the Shimano XTR wheels?

Tubless with a rim strip can be a great alternative to UST, as long as it is a thin piece of tape just to cover the inner eyelet. You maintain the weight of the regular rim by not having to deal with the brass threaded eyelets and takes weight off the rim by having the second hole.

No holes in the rim bed, so a true tubeless rim.

The Fulcrum PDF catalog says that the nipples are guided into their seats (holes) via a little magnet.......

Looks to me like you insert the nipples one at a time through the valve stem hole and then drag/guide then to the apropriate hole via a magnet along the rim bed. This would of course require a ferrous nipple or part there of, something that must be a fulcrum proprietary piece.

Sounds reasonable. So there is finally an alternative! :banana:

@ TheMontashu: I know and use rim strips but I still think the UST system is more convenient because you don't have to use sealant. I haven't managed to seal a non-UST rim/rim strip/UST tire setup without sealant.
BTW: the holes in the rim also weaken it and don't save a whole lot of weight. I am soooooo waiting for the 821 from Mavic!

Yes, it is truly a bonafide UST compatible tubeless rim/wheel. Fulcrum has had UST/true tubeless wheels for a while now. I wish I could tell you how the nipples were put in place but I have no technical info as of yet from Campy/Fulcrum USA.

Construction on the Fulcrum Redfire is top notch. Front wheel is slight over 1,000g and rear is just a hair over 1,100g.

Fulcrum has a UST MTB carbon rim/wheelset.. Fall in line suckas...these wheels will be hawt. Now back to the 40lbs jiggamathing Dh bike thread topic. :p
Been posted before but I had fun "tagging" my friend's M6.

Is that a Sram Red cassette, or have they started prototyping the cnc steel idea on mtb spreads?

Those wheels look sick. I'm sure the price will be as well. :redface:






Hey no skid marks, what kind of frame is that you have? Just wondering. I can't quite read the font on the downtube. The susp. design looks almost exactly like the old GT RTS...

From what I'm told, all wheel parts are made in house.


True tubeless. Non-UST tire need not apply.

KATIPO, it's a new manufacturer from New Zealand.
If only GT had stuck with the design. Although I like the GT IT1 design, pity they stuffed the geo etc.

Talking about those wheels is totally worthy of this thread at that weight.
How wide are they?

I thought 2100 for the rear seemed a little heavy. My wheelset weighs about 100 grams more then that.

Eiither the site or Orvan is wrong. This is what is listed.

Nominal weight*:
front:993 g
rear: 1207 g
Crap, my bad. What I meant to say was that the wheelset altogether was around 2,100g. 1000g for the front and 1,100+g for the rear on the scale. I'll fix my previous post. But whatever... the wheels are lusty. They have a carbon rim UST wheelset too for xc riding.. yum. :p

it was the complete wheelset weight around 2,100g.
I tried Mavic's tubeless valve on it and it works. I know campy is know to be propriety on a lot of their stuff.

Pic on hanging scale?
Bathroomies don't cut it at this end of weightweenie-ism. In my experience they always give less than actual figures, but the real scale dispels all doubt. :)
QFT. I just don't see that being only 2 pounds heavier than my weenie SXT, but I'd love to be proven wrong.

Any fool could recalibrate a hanging scale, the local shop's 15minutes away and I never buy anything from them, so either take my word for it or kiss my ****. I rounded it up anyway, I got 16kg on the **** scales.

Remember he is in Australia on the other side of the world where they hang upside down. Everything therefore is lighter. It almost like the pull away from gravity.

Well it makes no sense to me at all, but I took it to the bike shop(forgot my damned camera)and it weighs 17.050kg/37.51lbs, I'm stumped, I weighed it ten times on the bathroom scales and got the close to the same reading every time.
Apologies all:redface:

Now 40.2 pounds. Added a CC 110 headset, sunline stem. I plan on getting the new Dee Max wheelset which should take over a pound off.

That sounds more realistic given the bike and build, 37.51lbs = 17.01kg btw.

Whoops, yeah, it was 17.050kg.
I still don't get how by taking an average reading off the bathroom scales could be so far out. I'll have to find some other hanging scales, the bike shop ones were just built into a bike stand type ones.

Yeah, I wasn't trying to be a dick - but I discovered the same thing when I got a real scale, the bathroom ones lie. You can buy digital hanging ones off ebay for pretty cheap (< 20au posted) and they are quite accurate I've found. Get the 20kg max ones for best accuracy.

Here is my project for the 2009 season, will be hopefully built by christmas.
Bought the frame, rear shock, headset, bb, crank, guide and seatpost used (4 months old) as a set. The rest is brand new.

Frame: 08 Devinci Wilson 4 M w/ Fox DHX 5 AIR
Fork: 09 Rock Shox Boxxer Race w/ short crown
Brakes: 08 Shimano XT M775 (203mm)
Wheelset: 08 Mavic EX729 on Hope pro II 20/150XL
Headset: 08 Cane Creek Double XC Flush
BB: 08 Truvativ Howitzer Team
Guide: 08 E-Thirteen SRS w/ bashguard
Crank: 08 Truvativ Holzfeller 170mm
Derailleur: 08 Shimano XT shadow medium cage M770
Cassette: 08 Shimano Ultegra 6500 12-25
Chain: 08 Shimano XTR/Dura-Ace 9 speed 7701
Shifter: 08 Shimano XT rapidfire M770
Seatpost: 08 Race face diabolus
Saddle: Velo saddle (300g)
Grips: 08 Specialized Lock-on Pro
Handlebar: 08 Race Face evolve DH
Tires: 08 Kenda Nevegal 2.5 Stick-E
Tubes: 08 Kenda Heavy Duty 2.4-2.75
Stem: 07 E-Thirteen Ali
Pedals: 99 Time ATAC

Im guessing 38.5 pounds. What about you guys?

I could easily save some weight by putting a E.13 LG-1 w/ Taco, going tubeless and putting a rock shox boxxer world cup. Would be about 2 pounds less that way.

That's a heavy build, you are lookinf 41-42 my guess. Your wheels, cranks, guide, post, saddle and bars are all pretty heavy. If you are running DH tires and DH tubes thats a TON of weight too

34.2...bathroom scale which then weighed me at 136. i was expecting both of us lighter.

i might go down to my shop tomorrow for a more accurate weight

2005 izimu paint stripped
dhx air 5.0
totem solo air
oro bianco 8"
evolve xc crank, dh bb, e-13 38t
truvativ boxguide
wtb rear hub
specialized front hub

thomson post
alias saddle
hussefelt stem
strip bar
x.9 short cage
sram dh cassette
x5 shifter
wellgo mags

i might throw on my xt cranks and ghetto tubeless the tires to get me under 34. maybe down the road i might do sunline carbon bar/am stem, specialized toupe saddle, maybe dmr pedals with their ti spindle, or wellgo mag ti.

we'll see how winter goes first...

I will know soon when i will put eveything together, pretty sure it wont be over 40, even with tires&tubes and all the heavy stuff.
You have a bunch of parts in your build that, given what they are, could be significantly lighter. Like your rims, cranks, chainguide, BB, stem, seat/post and your bars. Either way, it'll be a sweet build!

Syntance stuff, Carbon post. Some nice parts you've got there. I only wonder why the steel spring? Also what pedals are that? Or just give us the full list ;)

BTW. I'd be very afraid of using 5.1 DT rims.

Yes, where I ride the cranks and rims would be dead on first ride but from the picture it looks nothing our rocky trails. Nice build for sure.
