But as they haven’t publicised the sprocket size nobody knows
Ask nicely and I’ll go and count them. Brompton Junction Covent Garden is 300m from my new office. I might take a test ride too. I won’t be buying one though.
When I rode my Rhino, I liked the Alfine. So much that the Genesis IO I replaced it with had the same hub. But then I discovered single speed and never went back. The biggest issue for off road was the limited range of decent 406 tyres. That now seems better. Brompton basically reinvented 16” tyres. The old 16” was not the same ERTO (305 vs. 349) and decent tyres for that size are still very limited. My Tactiv has that size
One point you won’t see is that the powder coating is mentioned as robust. The Junction test C-range have the same, and it wears off at the fold clamp pretty easily. Expect the same
