So can anyone shed some light on why there are those tiny little horizontal grooves on the forks of bikes - you know the ones that run around them, go on for about a couple of inches and the its smooth again before they start again.
And I mean everybike Ive looked at has them. Sure there must be a reason and not a design copy accross all makes and models.
anyone?
there machine marks thats all

I wonder why no manuafacturer machines them out completey so the whole fork is smooth?
I was told by an old tradie many many maaannnyyy years ago when I was an apprentice that the little grooves around a turned piece of alloy or steel tubing were there to give strength to the turned object. (I asked the same question)
So I took it as "Ok Fair enough" as a 18 year old would.
Believe it or not!

harley do
Also extra work equals more wear on tooling and more time to do the job, which has to be passed on to the purchaser/user! [roll]
On an already expensive piece of componentry, this could make them just too expensive. :o

yeah, that must be why Ohlins cost a packet, the bloody little rings ;D
do you mean the machine grooves that run the full length of the fork leg? or the 4 or so grooves at the top of the fork leg usually about 5mm apart?
paul.
wouldn't the 4 at the top have to do with leg adjustment to determine head angle/rake?
Hmmmm, thats a point!! ???
Yeah I thought they were so you could drop your forks through the triple evenly?
But I'm just a humble picture taker.
yep, they are, i didn't want to explain that cause it seemed really obvious and i didn't want to seem condescending.

is that like when your visor fogs up ?
it's when I rain down with snobbery! [laugh]
(hey, I thought I spelt it right...no little red line)
condescension vs. condensation
yep meant the teeny weeny lotsa fine grooves. so thats the consensus. machinery wear, cheaper to keep them rough. so why even bother I wonder, why half smooth and half groove. Smooth and groove! Shake n bake baby!
Sorry got carried away there... :o
