Bolt on cable stops for down tube?

[20130814]

Hi,

I have a bike frame onto whose down tube has no braze ons for cable stops which can be used with e.g. thumb shifters mounted on the handlebars - it's completely smooth and devoid of any bits or pieces.

I wondered if anyone knows the correct name or possible suppliers of a bolt on clamp that can be used to replicate the kind of setup shown in the image attachment on this post - e.g. cable stops? Ignore the brake lever hanging down - I just mean the cable stops welded to the frame.

Any advice much appreciated.

Thanks

I have a new unused one of these 28.6mm, double slotted version in silver, could be yours for £5 inc post?

Thanks for your reply - I'll measure the down tube diameter this evening and let you know.
Much appreciated
