A battery of questions loosely involving Rear casette problems! 1996 D'back podium1.0
I have a habit of talking and/or typing way too much. I will do my best to convey what I need while avoiding the horrible INTERNET TLDR problem. (Just finished the post - I failed folks)
That said, I have a probably not so unique situation: I picked up what seems to be a (1996?) diamondback podium 1.0 frame for about 100 at a community bike warehouse, and the only remaining things attached were the rear brake calipers and integrated shifters - thank the lord.
I have volunteered in this bike shop for several months over the course of the years I lived in town, and am somewhat of a spotty knowledged, amateur mechanic. It started out with fixing flats, but nowadays I can restring brakes and adjust all manner of brake calipers and derailers and this and that.
The bottom line is I slapped what should have been basically stock everything back on the bike, the brake calipers match brands and fit the frame, shifters work forward and back on both sides, wheels are great and I have had a great time riding for the most part. The problem arises I BELIEVE in the rear cassette, and the chain, and so begin my battery of questions.
The only cassette that fit and was in the shop that day was an 8 speed road bike cassette, of which the brand name I don't know. When I put it on it was baaaaasically having a bad day. Each sprocket could rotate independently of the rest, a trait that is frowned upon for gear systems. Fortunately with a wrench on hand I tightened it up to a workable level, and slapped the matching chain on.
1) This chain had one fixed link, I bent and smacked it until it was workable
2) The smallest sprocket is warped, though still usable.
3) Probably as a result of non optimal casette+chain, there is rubbing on the front derailer for a good amount of gear ratios.
4) Shifting is mostly workable, though it seems like I'm not getting a full 8 out of the rear gears. possible skipping.
5) One particular gear seems to 'jump' about the same place after every few pedals, possibly the chain link issue?
6) When using the non jumpy gear, the bike works wonderfully, but the weird gears are in the middle. I know about derailer limit screws, but not about tension adjustments.
So that was my probably TLDR history of me and this bike. My actual intent is to probably just buy a rear cassette that isn't broken from day 1, and to replace the chain along with it. The forum tips suggested to hit up shimano's helpdesk, but I believe this bike might be too old?
How would I go about finding a working 8 speed rear cassette that is spaced right? And its companion chain?
What do any of you gurus think about the issues I described? In the time before I get a new cassette I can probably fiddle with the derailer, any advice?
