Downtube Holes, Raleigh Technium RT600

Ran into something that I hadn’t seen before so thought I’d put it up here.

I bought an old Raleigh Technium  (Raleigh Technium RT600) frame on Saturday for $15.00 which included Shimano 600 shifters, headset, crank, brakes, bottom bracket.  Shimano 105 hubs laced to Mavic open 400 rims.  I think they went for around $1,100.00 back in the early 90’s and I’ve always liked the technium frames.  In case you don’t know about the Technium frames they are made out of different metals for tubes and “lugs” and are bonded together instead of welded.  I’ve never seen one come apart and my Raleigh Peak mountain bike that I bought in the 90’s has been pounded on and is still going strong today.

I have enough other components in my “warehouse” to put the entire thing together so for $15.00 I couldn’t loose.

Anyway!!  The one problem I noticed with the frame was that at the spot where the downtube shifter mounts should be there was a hole straight through the tube.  This was obviously not something someone did themselves but was part of the original design of the bike.

After some research I found out that this was done by a couple of manufacturers and that there was a post that went through the downtube at that spot and the shifters threaded onto it.

This is all fine and dandy but what do you do if that post is missing?  I mean it’s not like you can order that from QBP or something.

Then I came upon NOVA cycles supply!  (they were actually in my bookmarks but it makes the story better)  and I found this!

A lever boss kit!!  As it was less than $5.00 I just ordered it to see what would happen.  It arrived in 2 days and here you go:







The thing fit perfectly:







During my research I didn’t find much on this topic so hopefully this will help someone else out.  Bottom line I think is if you have one of these frames, DON’T REMOVE THESE SHIFTING BOSSES!!.

Will post more pics when the bike is done.







I’m out

    Thanks! I have an old Cannondale to work on and your post has saved me a lot of headache/heartache in tracking this part down!

    • Cannondale dude

      Did this end up working with your Cannon dale? what year is yours?

      • Goog Smells

        You know, my mechanic said that he would take care of it so I didn’t end up ordering the part. However, my mechanic is backlogged and hasn’t had a chance to deal with it yet. I might still order this guy and if I do I’ll let you know how it works out.

          Any updates of this working with the oversized Cannondale tubing?

          • Goog Smells

            Hey Brad,nnnSorry! No updates yet. I’m back in school and have not had the time to follow up. I’m out in ~10 weeks and I’ll definitely have answers then. I’ve gotten a slew of emails about fixing bosses on older Cannondale bikes (all related to my first comment), so rest assured that if I ever do figure it out I’ll update everyone.
