EDIT: These issues have since been solved. I was just answering an old question from 2 months back that someone brought up. Bike rides like a boss now.
Ok so I've been spamming this site for the past week as I fixed up a 58cm PSN-10 (Super Vitus 980) I picked up off ebay for $280. Pretty solid condition, no cracks, no rust, has all original components (Campy crank, modolo speedy brake set, mavic module-e 700c rims, weird quill-stem, etc etc). It even had the original pearl handlebar tape (which I've since removed). I replaced the brake cabling, threw in new Vittoria Corsa Open SC II tires and a couple tubes, cleaned out and re-lubed the headset, cleaned up the frame a bit, then took it out for a spin.
I've read a ton of reviews on this site about this bike and thought it might end up being a bit whippy at 58cm. I'm 5'11 and weight about 160. I'm used to riding my older mid 80's Peugeot at same size and I have to say this SV980 seems very whippy/noodly compared to my lower-end Corbier. I still plan on taking it to a bike shop for a proper tune-up since I'm no serious bike mechanic but to add more detail:
When I place the bike on a bike stand (rear wheel propped into air) and spin the pedals, the bike seems to wobble back and forth a biiiit too much which makes me think maybe the wheels aren't radially true. Or is this just normal? I threw my Corbier on the wheel stand and sliiightly did the same thing. Some wobble back and forth but absolutely not as much (maybe cause the bike is heavier?).
I definitely would like to sell the Corbier at some point and hold on to this SV980 PSN-10 but I wanted to see what suggestions others may have.
Other things to note:
-Haven't touched the original spokes/rim/hubs
-Haven't touched the BB (which appears to be fine)
-Owner gave me what appears to be the original chain but I should probably get this replaced (I added some chain lube on it).. but when switching from the big gear to small gear the chain sometimes doesn't engage perfectly (sits slightly above where it should be... clearly not super safe).
-I hear a creaking (like a quick bird chirp) sporadically coming from the front wheel when I'm riding and even when I just freely spin the front wheel in my living room. It doesn't seem to be tied to a specific point of when the wheel is spinning, just sporadic. My intuition tells me it's something to do with spoke tension.
I'm not feeling super comfortable on the bike juuuust yet though I've given it a spin around Central Park and I can certainly appreciate the speediness of it due to the new tires and overall lightweight. I suppose part of this could be caused by just not being used to more of a race bike or something.
Anywho, I'll look to bring it into a shop this weekend and explain everything as a real mechanic hasn't looked at the whole thing yet.
