Title: Whats their purpose? Post by: Justo on November 10, 2009, 04:40:21 PM 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? Title: Re: Whats their purpose? Post by: bazz20 on November 10, 2009, 04:50:28 PM there machine marks thats all
Title: Re: Whats their purpose? Post by: Justo on November 10, 2009, 04:52:46 PM there machine marks thats all I wonder why no manuafacturer machines them out completey so the whole fork is smooth? Title: Re: Whats their purpose? Post by: vossy on November 10, 2009, 04:58:35 PM 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! Title: Re: Whats their purpose?

On an already expensive piece of componentry, this could make them just too expensive. :o Title: Re: Whats their purpose?

Post by: loony888 on November 10, 2009, 11:11:51 PM 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?

Title: Re: Whats their purpose? Post by: mattyvas on November 10, 2009, 11:42:00 PM Yeah I thought they were so you could drop your forks through the triple evenly?
But I'm just a humble picture taker. Title: Re: Whats their purpose? Post by: loony888 on November 10, 2009, 11:47:53 PM yep, they are, i didn't want to explain that cause it seemed really obvious and i didn't want to seem condescending.

(hey, I thought I spelt it right...no little red line) condescension vs. condensation Title: Re: Whats their purpose? Post by: Justo on November 12, 2009, 08:35:38 PM 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 |
