Yes, that's a possibility but with an entry level Tourney derailleur, a 7 speed freewheel has a much higher probability.

Index vs. Friction?
Friction shifting teaches you to anticipate shifts in advance, and create muscle memory and "feel" about where you want your chain (via the shifters) at a given time. In order to create a consistent cadence, you learn what works, where it works, and how you make it work. You listen for tell-tale sounds that the chain is moving and then the silence when it gets where it's going, coupled with the feel in your legs of the difference in gear ratios.
Moving from friction to index takes a lot of the muscle memory out of the equation, as the chain will go a specified distance for each click, and you don't have to worry about it "sitting right." You listen for and anticipate the click, then the silence as the chain settles where it needs to. (If properly adjusted). It leaves multiple-cog shifts less to chance. If you retain the anticipation of your shifts and strive for a consistent cadence, it's not that different, but it's less prone to you being "off" a bit.

Everyone needs to look at the dates of the posts. This thread ran its course in 2014 and was dormant until Kyle revived it with a sort-of-unrelated question.

As a kid in the 60's and 70's I grew up with crappy Schwinn friction derailleurs. I forget what brand they used. I hated them. When I got Shimano 105, SIS in the late 80's it was like an entirely new experience. Much prefer the SIS.

The problem is the people who are not reading the whole thread while noting the dates of the postings.
