Someone contacted me a week ago who was a referral from someone I sold a bike two a year or two ago. It's always nice to get a referral. She brought over a small Specialized Allez frame and much of the drivetrain, minus wheels.

I'm going to get it built up for her for as cheap as possible so she can see if she likes the bike. It came with what appears to be 6 sp Suntour DT shifters that can run in either indexed or friction mode.
My question is, being 6 sp (5 clicks) will the rear DT shifter index with a 6 speed freewheel? I've never seen a 6 speed cassette so I'm assuming the bike originally came with a freewheel wheelset?

I'll post pictures later in this thread.
