Birre

Rockman Björn frame, rockman forks, bar, stem, rims, cranks, front hub. Reset ti bb, chris king headset and rear hub, hope tech rear brake, mono trial carbon in front, rainbow coloured ti spokes in rear and (soon) in front wheel. ti and alu bolts throughout. This bike is about 180 grams more than my previous bike (haven't built front wheel with ti spokes yet and 145 grams heavier frame) so that should be around 7,2 kgs

New ride! Rockman Slate XL frame and parts except for some chris king parts, ti and alu bolts, bladed spokes etc Big thanks to Rockman bikes and Tarty for hooking me up as always! more pics on : http://www.observedtrials.net/vb/showthread.php?t=43971

i might be somewhat partial:P but natural comps is what it´s made for! and i guess it was my bike you tried? with rockman forks the WB is 1013mm and not 1025mm as stated on tarty with some other fork.. i also got the bike you tried for sale 4 months used with loads of new parts on..

No sky, but with somewhat real tyres on!

I wanna know the weight as well, since my turned out 8.40 and it has both CK hub and headset witch is not the lightest parts...

i wonder who came up with that idea

+1

dunno yet, it´s from the future!

yes, and total bike 6990...

i know the frame is 1290 grams.. mine is still 200g lighter:D

The reason why i say my rear tire is about 60g lighter is of that reason, i know for a fact i shaved my tire 60 grams, but i don´t know how much the tire on the ozonys wheight.. so no guessing here... my point beeing though that there is no way this bike makes up for a 200 gram heavier frame, 110 gram bash, 120 gram spokes, 60 gram rear tyre just by getting lucky with a component that is slightly lighter that the ones i got.. belive me when i say i have built some fancy bikes that on this level a couple of hundred grams is not easy to find...

Ofcourse i have carbon leverblades.. My front tire is lightened about 60 grams, front rim about 50 grams and rear about 45 grams. fw system that he has is 38 grams lighter than my setup, pedals about 30 grams lighter.. grips?! im no math genius but it still does not make up for it, where talking abut 400 grams that is lost somewhere...

Would like to think that there is more to say, since i just built myself a bike based on a frame that is +200 grams lighter than the ozonys curve V2, with similar or better components and mine is 6.99 ( i also use the park tools scale ) From what i can see the only thing i got on that is heavier is the rockman 165mm cranks and the rockman 3d 20" stem. On the definitely lighter side is a +200 gram lighter frame, the same rear tire with 60g shaved of, ti spokes witch is about 60 grams lighter than steel, only tt ti half bash so no bashplate +110 gram, lighter rear disc... that´s like 430 grams in the lighter side, vs about 60 grams on the heavier side.. so where is the other 400 grams taken from? So feel free to explain this to me?

about 40-60 grams/ rim if where talking 20/19" so about 100 grams for a dd mod, and since its free why not?!

ive got a 19min vid from koxxdays 05 that i made, dunno if thats the one you mean? if i remember i can upload it this weekend:)

i would still say that there is way less modifications to weaken/lighten parts than on most other light builds. Only modifications is the rim sidewalls and i little bit on the king axle...

borrowed the bb from my stock and put the race wheels on:) (frame color is not final, testing out a new anodizing finish and also there is tractor graphics on this frame:P ) looks neat with countersunk 15mm m6 ti bolts and alu washers. ti spokes with alu nipples. rockman hub and rims. ck bmx/disc hub in the rear.

ooh shit Sherlock

hahaha yeah right! ill get some photos up soon but a guess then the comments are going to be photoshop ffs!

you will see the spec, finishing up the race wheels any day now and then getting the ti bb in a few days aswell.. but actually there is nothing super special, rockman frame, fork, stem, handlebar, rims, pedals, cranks, hope brakes, king hub in the rear and soon to be ti spokes and bb..

dual disc;)

The 6000 and 7000 series aluminum is between 35-42 ksi. k-alone is 45 so not that big a difference. These tubes with scandium is 68 ksi, witch makes quite a difference. Titanium for example has 85 ksi. (ksi = pounds/ square inch, 1 ksi = 1000 psi ) more pics and specs later on, and as i said, 7.4 with mostly standard rockman parts, rear king hub and a quite heavy rockman fork i recon below 7kgs isnt that hard if you get the drill out and compromise some parts...
