    Shimano 3x7 TZ20 right shifter friction?

    I'm looking to get a set of these to friction shift with shimano derailleurs and a rear suntour cassette. Because it doesnt index well with shimano indexing and suntour cassette spacing, I'm wondering if the right shifter of this is friction. The review says so but I haven't read it anywhere else.

    What about upgrading your drivetrain? Shimano 7 speed cassette $30, very good Shimano derailer $30-$50 (Tourney is just $15), or just use your old one, and set of good Shimano shifters is another $20-$30. Check sales or EBay... I remember the shifters from your link very well...they never worked good, but maybe it was just my luck.

    I've got a full LX drive train but the rear hub is a suntour cassette. Ive got another set of brake levers I can use to swap the lx brake and shifter combo so I was hoping to use these shifters in friction mode as an $8 fix to my problem. Do you know if it runs the rear in friction?

    Those do not look like they have the switch that some of the older early Shimano SIS thumb shifters had to switch between friction or indexing.

    Personally I would just get a Shimano cassette or Shimano spaced freewheel and call it good.

    I'm fine with friction shifting 7 speed derailleurs .. it is a simple hand skill to learn.
