I’m using it on my Macbook Pro M1. No crashes. Flawless performance. Great graphics. Much better than Zwift in fact. And ERG works just like with any other indoor training app with my Elite Suito combined with Favero Assiomas. Nothing to complain about. Only minor issue I have with it is that it only supports Bluetooth. No ANT+. That could be an issue for some devices.

I never played with spacers but doesn’t that just affect the travel on the compressed side of the stroke, acting like a stop? What I was thinking was reducing the stroke length so that both lower and uppers could be shorter, to minimize the overall length and allowed a lower front end

I wish there was some descent budget 24” fork with 50-60mm travel to lower the from some and reduce the stand over. Almost tempted to try some of the cheap Chinese options, bucklos/bolany

I have been looking for a 24" build for my daughter.  finally settled on going with the BXT 24er frame.  I found a Reba 26er fork and I am going with Deore brakes and drive train and some kids 140mm cranks.  for wheels I actually went with Stans Crest mk4 rims.  they are lighter and wider than what I could find elsewhere as well as slightly cheaper.  as parts come in I will post some pics.
