Bracket... on or off ?

[drystonepaul]

This is strange, i have a 92-93 kili pro e-stay that i've had from new and it doesn't have that brace, due to Maguras being fitted. But i've just brought another Kili pro e-stay (year unknown) but this one has the brace and Magura's!!!??? The other thing that i found strange is that the one i've just got has a lot of LX components, my original one came with DX throughout. Can anyone shed any light on this.

This sort of thing seems fairly common on early Saracens. The 1993 'Race Elite', for example, was built up using 'leftover' 1992 'Kili Racer' frames. A new set of decals was produced and it was built up with an odd mix of components ranging from DX to Altus. It was a case of no two bikes were the same.

For the 92 steel e-stay range, the higher end e-stay Kili-Pro and Kili-Flyer range had Maguras as standard equipment and no brace. But the even higher up Kili-XTR and Kili-Ultra were specced with cantis and thus had a brace.

Any photos of the other frame would be useful to ID it.

leave it on and the vees, too

Sod them both,take it off,get discs juried on to it

DO NOT CUT OR MODIFY A FRAME!! you are asking for trouble!

Just out of interest, why ? It is a non stressed part

Any stress within a frame looks for the weakest point, hence why you have a brace near the head tube. All frames have a certain amount of flex and by making the walls of the frame thinner, e.g. grinding away welded parts, you then open a week area for stress cracks to appear.

The inside of a tube on an area where it's been welded can in some cases actually be thinner, the strength comes from the joint of the original tube and the welded item.

I have played with making my own frame designs on custom bikes and have learned the hard way on many projects

So a 'badly' removed / grinded off item that thins the original tube section is a stress raiser - I understand that but surely that is operator error !

Interesting, never knew or have seen witness to that - Is that only in the case of a bad weld ? I have only ever seen additional material due to weld penetration. I understand that the nature of the welding process can introduce material property changes (i.e. weakening in some materials) without proper care and heat treatment etc but as the weld itself is a natural stress raiser could it not be argued that it is better not to have a weld in an area where it is not actually required ?

Probably not for this thread but I would be very interested in reading / seeing pictures etc if your ever want to post them up ?

Please don’t think I am baiting or taking the piss – I am genuinely interested in stuff like this
