Can someone take a photo of their early Cannondale and tell me what goes in this hole (see arrow)? I'm guessing that it's some sort of barrel adjuster?
If its just a cantilever brake cable stop you need have a look at the attached photo.If it helps I am happy to post you one as I no longer need mine as I have gone over to V brakes on all my Cannondales.
Have you found the Vintage Cannondale site yet? If you go to Info/serial Numbers and then scroll down to restoration tips you will see their solutions.
I think Frank is right. I've got a similar brake cable stop on my 1993 M2000 frame and M600 frame. The nut needs to go above the 'bridge' so you're able to tension the outher cable (when the innercable is in place, it is impossible to lose the cable stop). Take a look at some pictures here: viewtopic.php?f=6&t=168022&start=10 or here http://commons.wikimedia.org/wiki/File: ... M2000-.jpg but on the other end.... :?:
We seem to have some discrepancies… Looking at the very pixelated image in the 1987 catalogue I think Adrian’s ferrule is right for my bike. I guess Cannondale changed to barrel adjuster later on? Let’s wait for Pierre to tell us what’s right!
