i'm about to go SS ..
I've got a busted rear der cable and am effectively SS as the front shifter is screwed in the cold..it;s old and tired. I'm 42x16-ish. I've got my single cogs to have put on the cassette and keith has a new shimano front ring/spider for me. Looking forward to ditching the gear off the bike. After that will be stiffening the front end.
