Bottom Bracket Cable Guide - No Thread?

https://i485.photobucket.com/albums/r...n/SDC10284.jpg

I have this frame which came without a cable guide beneath the bottom bracket. The BB shell has two holes in it, one 5mm and one 8mm. Neither of these have any threading. Is there a specific type of cable guide made for this? If not, how do I get one that fits (without glueing it on!).

Thanks

One hole is for water drainage the other is for the cable guide.
I do not see the brand of bike but you should be able to get a cable guide from your local shop or possibly frame/bike manufacture by calling them or via internet.

It might be a press in. These cable guides have a little nub on the back that gets rammed into the frame.

I just grabbed a brand new Shimano guide from an Ultegra kit. The mounting side is flat. It has 2 mounting holes but no tabs.

Do you have a picture and/or know where I can get one? Thanks

It is a Raleigh Special Products steel 853 frame, information about Raleigh Special Products is scarce at best.

I've used several types of BB cable guides. Some pressed in, some screwed in. The guide will stay in place from the pressure of the cables so a little piece of double sided tape will do the job to start with. On my custom frame I initially had the guide screwed in but a closer inspection when I did a rebuild showed that the hole wasn't positioned quite right and I had some cable rub on the frame from the front derailer cable. I repositioned it and held it in place with double sided tape and it works better now so before you get so worried about it make sure its in the right place first.

If you are up to it, you can pretty easily tap the 5mm hole to fit an M6x1 (6mm) threaded bolt. It's steel, so you won't risk starting cracks or anything. You can easily do it yourself with a tap, tap handle, and oil, or you can take it to any metal shop; a bike shop might have to tools to do it too. The only other option is to glue it on.

You can easily drill and tap a hole or two for the cable guide. I did it on my old Basso Ti and it worked perfectly.

Second. A dab of 2 part epoxy and you're done.

Try a pop rivet before you install the BB. bk

GOOP is a good adhesive for this; it's waterproof but will release easily if you need to pop the guide off.

I've also seen these pop-riveted on; that wouldn't require threads.

I bought some of this https://ecx.images-amazon.com/images/...2L._SS500_.jpg a while back to glue a shim on to fit a FD on my other steel frame, think that will do the trick? Pretty sure that wont harm the paint if I have to take it off.

Thanks for all the responses!

Could you bolt it on the other side? Raleigh special products frames are excellent. I have an 853 cross bike made by them. Remember that during the mid-90's, Raleigh UK were world leaders in steel and Ti bikes.

Not enough room. Especially if you're going to run cart bb. The op should find a bb guide per post #4 or just glue it.

The glue isn't really necessary anyways. Cable tension will keep it in place otherwise.

I know this is an ancient thread, but I was looking for the solution and wanted to post my experience for others, namely that cable tension does not hold my guide in place. I have an 83 Trek frame with no hole for a screw / press-fit, and thought I could just have the guide sit there. It works until it doesn't, and then it takes me a couple minutes of poor shift quality to realize what's happened. I'm going to try the double-sided tape route next.

As a couple of others have stated, I installed a BB guide by drilling a hole and tapping it for a small bolt. The bike that I did that to came with a clamp on guide that was mounted above the BB.
