Post links , on your narrowed choices..


I just have a Bike Friday , their built wheels probably cost more than you may want to pay ..
given you are saying you only spending $500. on the bike..

What hub you want? Shimano has 8 (Nexus & Alfine)& 11 speed Alfine IGH but there you need a 135 width

Sturmey Archer is offering several options ..
Then there's the whole Derailleur drivetrain sector..
