hey guys, i'm having an issue on deciding what to do and if it's even possible. i have shimano 600 SIS components and it's a 6 speed uniglide system. I have better wheels that i want to use (shimano 105 with Mavic ma2 rims). The rear hub is an FH-1055 which i believe is a 7 speed uniglide. Will i be able to remove the 6 cogs off the ultegra 600 and slap those onto the 105 free hub without any issues?
I also tried to remove the the cassette by using a chain whip and a jerry rigged chain whip (my brother holding a spare chain around the freewheel while we go opposite directions) and the 13t cog would not budge!
Any tips would be helpful right about now, cheers!
