bolt sizes for 90 degree bars

[AaronA]

i use to know the right size but not any more btw its for a pro modle headtube

 

[coleharbaugh]

I only know the thickness
one of the 5/8
and two of the 5/16

Measure the length yourselve, so many threads on this.

LOCK?

 

[AaronA]

i already know what length i just needed to know the sizes

Just use a old a headtube .

 

[AaronA]

[Gary Ryckman]

Just use a old a headtube .

def would do that and play around with the bolt sizes and to be honest im pretty sure you dont want it 90 degrees.
Im usin a old a headtube with the 3/8 in behind the headtube and 5/16 in the front and thats pleanty steepness for me

 

[Joe Riley]

get a yaak headtube. its a 90 degree angle.

 

[kolbycrouch]

^ yes it is, stays that way too.

 

[Humma]

90 degrees, that would be wierd to ride..

 

[.BenDajkovich]

^well that helped him to find what sizes didn't it? arron u can do the math but say if u get 2mil thicker at the back get 2 mil skinnier at the front that should take it to around 90 deggrees (i think)

 

[gerkin of honour]

8mm in the front and bottom and 10mm in the back. verticle bars no problems! and the length is 75mm

 

[idk47]

7/16" x 2 1/2 in back

And 5/16" x 2 1/2 in the slot. That's what i rode on my old a and it was almost 90 but less because of the old A part.

 

[domd]

my old a is already straight up with out different bolts.

You dont want ur bars 90 degrees. Its horrible and hard to ride. Just use a old a headtube. LOCK.
