Shimano 7 speed and the different between Freewheel vs Cassette

Shimano 7 Speed

First off I ordered this Shimano 7 speed freewheel after I discovered a faulty freewheel on my new schwinn solution which I ordered here on amazon. I quickly learned that it was indeed a freewheel I needed not a cassette.

A freewheel is a

SRAM PG990, the hottest cassette

SRAM PG990

This SRAM cassette does everything you want - it shifts great, is light weight, lasts a long time and looks great. I have over 1000 miles on it and it looks like new and always shifts very quick. I definitely recommend this item.

I can say I get much longer use out of the high end Sram cassette then

Getting up hills by Shimano Megarange Freewheel

The Shimano Megarange Freewheel is fantastic for getting up hills when limited by a 40/52 double chainring set. As my previous freewheel was already starting to fail, this was a $14.00 replacement vs. $150+ to replace the crank and bottom bracket to get a smaller small chainring (and even more expensive to get a triple).

The only problem was that my derailleur was not long enough and would rub on the megasprocket while I was on the second sprocket. While I rode about 600 miles in this state, I ended up ordering a long travel derailleur ($40), but I still feel this was
