Thank you all.I only have experience with derailleur system and these coaster brake, roller brake etc is new to me.I haven't bought anything yet no wheels no framset at this stage.is building wheels on 3 speed hub cheaper than buying complete set? I want regular 700c with normal hub in the front.can I use any shimano nexus 3 gear hub with rim brake? I see on google some is compatible with coaster roller disk brake etc? I try not use above brakes! If u buy nexus 3 coaster brake model then do I have to use coaster brakins system or any rim brake will do? Also SRAM I motion 3 which is cheaper option? Nexus and I motion requires 135 rear spacing?? Also is there a bar end shifters that works with internal gear hubs 3 speed?
My plan : buy a frame set , build 700c wheels on 3 speed hub, put bullhorn with TT brake levers for rim brakes, and use bar end (indexed possibly) shifters to change internal gear hub.
Can I use internal gear hub on normal road bike frame set? Thank you everyone in advance
