ya i tried a search. so does anyone know the head angle of an xtp or levelboss. thanks
i am going to say 74, i think its the same as the LB
74? thats zebdi and short echo stuff.
isnt it like 71?
It's def. not 74, I think its 71 or 71.5 depending on what fork you use.
headangle has fuck all to do with fork.
Headtube angle is always the same regardless of what fork you use because it is a part of the frame design.

Umm I meant it had to do with fork height. Some people run longer or shorter forks which would change the angle a bit.
word. i was going to calrify that teh actual headangle is a constant, where as teh fork is always a variable, so its pointless to say that the fork changes the headhange, because it doesnt, it can only change the WB. sorry that i am a jerkoff.
head angle on a frame is constant. however, when you put on a long fork in can rake out the bike which makes it feel slacker. shorter forks will make the angle steeper. they also change the wb.
yea, that is what i was trying to get at...word.
alrighty thanks guys :joshers:
elan- you smoke crack where the hell are you getting this "74 deg head angle- everything good is steeper than abercrombie's clothing prices!" DArF.
71.4 deg on koxx xtp and lb.
i think it's more like 71.42 :slap:
DERSH 71.4 deg head angle with a 400mm fork. it's on the koxx website. it's been meausred by other sources. :joshers:
I disagree with just about all of the above so hears my angle on it:
so basically the headangle relative to the ground/axel height is decreased (slackened) as the fork height increases, plus the wheelbase is increased. The headangle is measured relative to the ground/axel height is it not? (if not disregaurd this entire post, but I think it is) Yes of course the headangle relative to the frame is constant, its welded on.
everyone should shut the hell up, drop everything they are doing, and download the anti-social skate video trailer.
Headangle is measured in relation to the chainstays. It's the angle basically between the plane thru the center of the dropout slot and bb and the plane that runs through the center of the headtube, Angle is measured as the acute angle at the intersection of the chainstay and headtube planes.
Although fork length and offset have nothing to do with the headnagle itself, yes, they do change the geometry of the bike. The headangle remains constant because when you go shorter/longer fork the bb also rises/drops so nothing really changes the FRAME geometry, but the overall bike geo does change. Remeber though, fork offset and length do affect wheelbase.
The combination of headnagle and bb height give the bike it's handling characteristics and contribute to stability. A low bb with slack headangle is inhernetly stable whereas steep and high becomes less stable.
A bb that is lower than the axle decreases headangle and higher increases it. A bike with the same fork, wheelbase, and chainstays may have identical angles of headtube while sitting on level, but if one has a bb drop and the other has rise, there could be signficant differences in headangle. The one wit the rise will be steeper than the slacker one.
Okay, got it? Now go play in traffic.
I've owned 4 koxx frames and I don't even know what a head angle does.
ahahah..yea, 74 was a pipe dream . i think i was thinking about the seat tube.aha...luckily i didnt try and defend that one, but i knew it wasnt right ,it jsut sounded so. anywho, my lb 1065 is 1075. that 10mm makes me feel super macho
I finally had to come out and say.......ELAN......STFU!!!!!
