Hi there. New hear and just saw your post. I bought my Vitus 979 in 1991, but all Dura Ace. I've added Ultegra sis 6600 ( I think) and now trying to fiture out where to get a ferrule or adaptor for the rear sis cable to fit the cable stop on the chainstay. Also concerned about intgrity of the bonding. It's been good but I read a lot about these bonded frames and potential for break down of that. I have 2 x recently experienced speed wobble... and wonder?I have a Vitus 979 I am restoring Serial # E100195 . I looking for photos of what it looked like in its original state , year ..etc .
any information would be greatly appreciated
Good point, it's amazong how small headset imperfections can make a bike handle horribly.In my experience, speed wobble is often a symptom of an over-tight headset.
What happened: Long curving downhill and was around 55km, it all happened very quickly. It was as though the bars "turned" and I went down. My knee and hip lost some skin but that's about all. A fleeting thought was that I hit a small stick... thought maybe a squirrel but for some reason my (vague) memory as that I saw a small 1" stick or branch maybe 1 foot long and if that was real rather than emagined, it seems to me I did not hit perpendicular, but almost parallel and hence that could have caused the front wheel to skid! I searched for a cause but could find no injured animal or sticks lolI have 3 Vitus 979s and 2 of them ( early 1980s bikes)have been ridden many times over pretty rough terrain in France when taking part in various retro events eg Anjou Velo Vintage.No sign of any joint failures.[Speed wobble is something different,I think- what exactly happened?]However, these are old bikes and something could go on them anytime, as it could at any time on much younger bikes.These were quality bikes and the fact that they are still around and rideable says a lot.Your bike is quite a bit younger than mine and you’ve had it from new so much less of a worry!
Re stepped ferrule for rear brake cable I think that the one from Velobitz may work ( UK company)
