I just got an old Trek 1100 with the Suntour Edge Group. I did research and couldn't find much about the Edge group. Does anyone have any experience with this group? (Is it any good?)

I have a similar bike. If you want to compare the position of the Edge group to contemporary offerings I'd say it is around Tiagra/105 level. It all works well, as did most Suntour products, but the 7 speed index shifting on the downtube isn't really state of the art these days...

Until it wears out, by then you might want a new bike and you will not have thrown your money away replacing good enuff stuff with better.

Suntour edge dates back to the 80's on my old Fuji I use to have- I didn't have any problems with the components they work fine and I put tons of miles them.

I am rather excited about the reliability, you see, the bike was free!
