I haven’t ridden it…but I’ve seen it.
That’s a 10-42 tooth cassette.
For comparison, here’s a 11-21T cassette.
XX1 Type 2 Derailleur.
Lockout button for easy wheel changes.
It’s hard to show in a picture, but the new linkage moves on a different arc than a standard rear derailleur…it’s really noticeable in person.
The cassette is a beautiful piece of machining.
My, what big teeth you have…
Relatively normal looking trigger shifter.
Size comparison to a PHOTOBOMB. standard MTB cassette.
Hard to tell here, but the chain is palpably thinner than a standard chain.
I knew it would be big, but I’m flatly amazed at how HUGE a 10-42T cassette is.
I’ll be curious to see how it looks on a bike. Not my bike. But a bike.
