Suntour barcon (front/left) slips
We have an older Burley Bossa Nova tandem with suntour barcons and the front derailleur no longer holds its position. I tried tightening the screw (with the little flip-out ring) on the right side of the barcon but that did not seem to help. I managed to take it apart enough to remove it from the bar, but have not been able to take it apart any further. Is there any maintenance/cleaning I can do, or parts that need replacement to get it to hold again?

You too!
I was starting to think I was the only person with a Burley Bossa Nova! I bought mine used last year and have torn it completely apart, had it powder coated and reassembled. I am having the same problem (started this weekend) and searched the forums using "suntour barcon". There appears to be a thread (fender1) with a similar question regarding the rear dérailleur, not sure it applies to our problem. Let me know if you have any luck. You might also want to post in classic and vintage.

Thanks for the link, I will check tonight to see if that also works on the left side and let you know how it comes out. If it doesn't work, I will post again in the vintage forum.
We've owned our Bossa Nova for almost 2 years and we have liked it very much.
Thanks!

If you had the part here in front of me I could "fix" it rather quickly... not having one in front of me... or not having to have done it in some time... I am not sure I could easily tell you how to do it on-line. ?? on the side opposite the wing nut there are two [or should be two] "nuts" a larger outer hinding an inner smaller one. Take the outer off and then make the adjustment you need.

Note: As best as I can recall, SunTour's indexed and non-indexed friction shifters were "dry" shifters and didn't need lubrication. I could be wrong on this point: it's been a while since I messed around with SunTour shifters.

In servicing them I used to use a light spray lube on them. Generally the only time they needed to be disasembled was to change their position [or tighten their "fixing" to the bar] Or as said to tighten the lever action.

I own a 1990 Bossa Nova, it has been a great tandem. I had issues w/ the shifters and switched them out with some tried and true Suntour Bar end rachet shifters circa 1980, not as elegant but work like a charm.
