the act of rotating the shift grip is certainly simpler, than figuring out the shift sequence
when you have a few double shifts of FD & RD to go down in order of lower ratios 1 at a time.. .

lower low may not be in the plan.. [than say a 22:36]

LHT Disc Brake lets you use the Type2 OEM end & 'speed',or Monkey Bone .. Cycle Monkey in NorCal is now, also Rohloff USA service center
and wholesale full range, distributor

the 'bone'; uses the ISO disc mount bolts .. Type 2 Torque stop fits over 1 of the 2 ISO Bolts as it is ..

You still have the Hubs Minimum chain drive ratio limit 2.35:1 (as I Recall) so 16: 38.. though with a smaller wheel .. [not an LHT]

Like Bike Friday .. what is on the edge of the warrantee's range is much lower than a bigger wheel

Eg the 16:38 with a 26" Wheel is about = to the 16:53 with a 20" wheel ..

Sheldon Brown's Bicycle Gear Calculator 16:38 inputing a 622-35 wheel . low [.28] is 18"; 26x1.5" tire, its 16.5"

BMX 20" its 12.4" (18.1" is 4th)
