Topic: Clip On trick

[chung]

You are not limited to having Clip On Handle Bars the exact size of your forks. So ebay shopping might get a little easier for those of you who are limited to CyberShopping.

I acquired a set of used TELEFIX bars from Sac Cycles in Sacramento California. I had to throw in the Plug because they are a great bunch of Guys and Gals that helped me on more than one FrankenBike Project

I measured the ID of the clamp and it was a couple of MMs to large. Jason ran to the back and came out with a couple of thin split brass Sleeves. I thought he was nuts. But other assured me that it was OK.

It works as perfect as if they designed it that way. (maybe they did?)

I later hammered the 450 into a parked truck @ about 50mph and although the switches were upside down and the bar bent/cracked, the clamp didn't move.
Pix available on request, happier shopping to all

Hey Chung - do you know what the external diameter of the adapters is? I was wondering if I could just buy the adapters to use for some clip-ons for my 400F. I would like to add clip ons but size 33 mm is an uncommon size and the Telefix items are expensive!

Simple math Bro. 35-33=2 Since the sleeve goes all the way around the fork, 1/2 0f 2= 1mm. So all you need is a sheet of soft metal 1mm thick.
There is a plus/minus on the exact size of the clamp. Hit the Yellow Pages and you can probably find something w/in a few miles of home. A lot of scrap yards sell metal as well as buy it. Try Wrought Iron and Sheet Metal, anything involving metal fabrication.

Mine happened to be brass but I don't see why you couldn't use stainless or mild steel, even copper?

I second your simple calculation bit. I think that's correct.

I'm not sure however that *any* metal sheet will work great. Various metals have different chemical properties. Getting copper sheeting could mean that they oxidize and turn green/gunk stuff up. Getting iron/stainless steel/aluminium sounds better, but I don't know what kind of metals will bind on contact under pressure. It could cause the shim to chemically bond to the bars or to the clamps... Then again, maybe there will be no issue at all...

check a table of nobility one here:

http://www.copper.org/applications/architecture/arch_dhb/fundamentals/arch_considerations.html

 the closer the metal is on the table the least likely you will be to have corrosion problems when installed bare.

 most metals shops carry shimstock in various thicknesses and materials. brass and steel being the most common, but aluminum is easily found.

 as long as the clamp is able to apply correct pressure, it's as good as direct contact.

That table should go into the FAQ's (if it isn't already  )

FYI - woodcraft sells clip-ons down to 32mm

And you dont have to take off the top triple clamp to install them.  I bought a set for my 750.

They probably used brass since it is very malliable and deform around the bars and clamps to give a good grip. A harder metal would probably slip.
