It’s not actually that much use is it? lots of sprockets but:
a combination of two Shimano Ultegra 11 speed cassettes
So no more gearing range than my old 1×9 speed MTB then?
It’s not fully indexed, just a bodged, over shifted gripshifter:
At the front of the bike they modded a SRAM XX1 Gripshift to shift through 13 gears. The first 11 are indexed while gears 12 and 13 are friction.
So what does it prove exactly?
That clown bikes with their comical Dropout spacing can accommodate some extra Cogs…. Wow!
I could have bodged that it my garage…
Now a 13 speed 10-50t cassette that might have been impressive…
