No, im sure it's onza I replaced mine with a Reset Steel bb and saved 150 grams

Onza bb? Urgg

Gees, defensive much I'm not saying your wrong, im saying i dont think it's as clear cut as alu is half the weight of steel and half the strength. When talking about a material's properties, there's so many factors: Compressive strength, elastical strength, resistance to fatigue, ect.

Your saying its half the weight, so you use twice the amount? From your logic, both frames would weigh the same, and be as strong as each other

Its completely different to walking over an airbed. In that situation, the airbed has time(seconds) to displace the air, and a large surface area which would allow the air to compress. All this allows your foot to hit the floor. With car airbags, they do de-flate, but when you hit them, the time of impact is fractions of a second, which doesn't allow the air to escape or compress.

From everything i've heard about BT, its a real marmite thing. Some people swear by them and have no issues, yet other times they treat people like absolute c**ts!

My try-all rims completely tit'd, so might give it a practice on that

You're used to a head bobbing action, aren't you?

Man up! because of the way carbon is, it does flex a bit more then Ally, but it will fatigue alot less than Ally.

Cold fusion! i've had it between ally and ally. You can also get cross-metal corrosion/fusion.

Yeh, i've just changed over to a Reset steel. Don't think ill be going TI axle any time soon, as im pretty heavy. But to be honest, considering its 150 grams lighter than my old bb, im not complaining

Thats what i thought at the £25 crank bolts. The bolts seam reasonably priced though .

Tarty bikes have a new range of TI bolts/axles. Doubt they've save massive amounts of weight, but they look f**king sexy!

Silly like you licking your face when you ride?

Ignore them, they've got nothing better to do. to be honest, I lightened my bike cause it rains in Cornwall 8 days of the week.

Turn the wheel over, use a block of wood and a hammer, and knock the axle out. It'll push the bearing out with it.

Looks about correct, It'd be the immediate space after you put the washer on. I had to do this to fit my echo hub to my trialtech forks, cause the hub's 10mm and the forks are 9mm. I did what trials hoe suggested because modifying a £35 front hub is far cheaper than a £120 set of forks if you screw anything up!

Kind of as with the Czar hub, the bolts go through the forks, rather than with a conventional hub where the axle goes through the forks. By the looks of the first picture, you'll only have to file the forks down a millimeter or two. I agree with you. but he problem with this is he'd have to file the bolts down, and they aren't that thick in the first place.

You'll have to file the forks down

*hand*

Scales are that accurate. And your point is?

I'd question this. I think 500grams is quite alot, especially in trials. Even if lightening the bike causes a placebo effect, who cares? It'll cause you to ride better, weather or not its your brain tricking you, or you actually having a lighter bike. William, i just recently lightened by bike by about 500grams, and this is what i did: Different BB : 148.5 grams saved cut the steer tube : 24.7 Grams cut every other knobble off : 43.2 grams Tock of chain stay protector : 13.6 grams changed the front wheel : approx 200/300 grams

Wanna explain why? Will using a straighter lacing pattern not give me the extra length needed for smaller and wider flanges?

I've got a stock hope pro 2 disk hub laced 3x to a onza rim (the one with the onza hogs stamped out of them and drilled sidewalls). I want to lace it onto a Onza sealed bearing non disk hub (http://www.tartybikes.co.uk/front_non_disc_hubs/onza_sealed_non_disc_front/c86p224.html). I know the hubs have different flange sizes, i was wondering could i get away with using the original spokes, just lacing it 2x/1x? I know this could properly be figured out with a spoke calculator, but that confuses the hell out of me Cheers
