I was going to build a custom ratio cassette for this but ran out of time to order what I needed. Maybe something for next year though. Think I'll ditch the 11, 12, 13 ish and keep the 32T end. There's also the option to run a 36T SRAM with Wolflink like the Wack Attack.
@skinny nice gears. Do you have a 30t inner ring? I assume the shift on the di2 is still good?
