Chicago-based nonprofit World Bicycle Relief (WBR) doesn’t distribute just any type of bicycle ??? it distributes bicycles meant to navigate the unimproved roads and rough terrain of developing nations, empowering populations to access healthcare, education and economic opportunities that would???
I wonder why you don’t see variations on those sealed three-speed gearboxes you used to see on British bicycles. They seem to have few exposed parts.
We do? They have internally geared hubs of up to 12 speeds now (but they are very, very, very expensive - check out Rolhoff, they’re pretty much the gold standard of internally geared hubs, if you want something more affordable Shimano Alfine is much more affordable and does 8x I believe)
I figured the old Sturney-Archer gearbox on the 80% rust Raleigh my dad used to ride was more on the lines of… affordable.
Yeah, but IGHs have come a good ways, you can get something really not bad at all for not all that much.
