There are many ways of setting up 1x9,10,11 system and some combinations of kit don't require guides.
Question - which carbon / alu finishing kit for CAAD10? Don't want goofy logos / stupid colours. Post needs to be carbon and layback. Stem, bars alu preferably.
We never used to bother on 1×6 TT bikes, and miss.ua rides her 1×8 shopping bike quite happily with no clutch/thick-thin ring/chain guide. Off road, it's probably a good plan to have one or more of the modern anti-dérailleurs.
^^ Haven't you said in the past that guides are not necessary on 1x systems?
Or was that just for on road applications?
