Da Vinci also does but they are expensive. Theirs are 130/150/170 or 120/140/160

125 mm for a 3.5-5 yo is a hard ask, they really can’t reach nor do they have stand over to the ground. But a kidback puts them really high. Crank shorteners on the back of a tandem have a big Q factor too.
Those Thorn double drilled cranks look pretty sweet. Definitely worth bookmarking by anybody looking for small stoker cranks. If those aren't short enough as is, then adding the ride2 shortener onto those would give a really good reduction. Not sure if Russ is dealing with JIS square taper or if his BB might be Powerspline. However it's cheap / easy enough to swap the BB to JIS if not already.
