I'd really like to keep the drop bars, may change them for different ones eventually.
Wouldn’t it be possible to use an index system for 7 on a 5 cog/speed freewheel, and just not use 2 of the positions?
Also I need a new front sprockets/cranckset. Mine is worn extremely and has a broken and chipped teeth, this is the first thing I’m going to change. Currently I have 52/39 could I put a 3 sprocket set on instead of 2?
