Bikes: 2008 Novara Randonee - love it. Would have more bikes if I had time to ride them all. Previous bikes: 1968 Motobecane Mirage, 1972 Moto Grand Jubilee (my fav), Jackson Rake 16, 1983 C'dale ST500.
Of course it's possible but to advise you we need to know what you want to accomplish by going down to 7 speeds, and which combos (front/rear) do you use now? We need pics of the left side of the bottom bracket to tell you what tools are needed. It does not matter if some are riveted (not welded) together, just if yours are. If so then you would either need a new cranset and possibly bottom bracket. Or no matter what you have you could just leave the front derailleur in one position. I would recommend that anyway to start, just to see if it's going to work.
There's no such thing as a routine repair.
Don't tell me what "should" be - either it is, it isn't, or do something about it.
If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.
Please take the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!
