Good info.
Was thinking the DA shifters are good for the option to switch to friction at any time. My first roadie was friction Suntour barcons and I loved it.
Wpuld prefer 9s over 10 simply because those are the chainrings and chains that I have already. Also the slightly wider cog spacing will help the shifting, especially with friction.
Anyone have those parts lying around for sale?
Also still looking for a suitable wheelset. Shimano freehub, rim brake, and ideally wide rims for 40c tyres. Must be stacks of these around now that everyone has gone 11s and discs.
