Thanks for your feedback. The chainring size almost does not matter as it´s the idler pulley that is responsible for the ant squat. On a 50T cog and a 30T ring you´ll have around 125% anti squat and on a 10T cog and a 30T ring it´ll be 100%. We designed the anti squat to be higher in climbing gears. The deviation to what you asked is minimal.

@mo3rki: we look at the linkage modell and check the forces under full compression to put them in consideration. I love bionic design but you need the maufacturing or it. At this point I believe we do reasonable if we would do this with carbon we should do it different. Glad you like the project. Cheers, G

@freestyIAM: Haha cheers for that, if this one gets into production it will take some time. Now it´s time to get them build and go testing. Yeah so stoke to do that ;-)

@Megazzz: I couldn´t agree more thanks for your detailed statement. Every design is a compromise and there is no "general" perfect. It can only get perfectly close to what you want it to be.

@optimumnotmaximum: I like the work of poygon in general and I don´t have proper data to analyze their design so I´ll just refer to our first episode where we explain the general findings on standard 29er bikes.

the bike will have internal cables as shown in E6 It will have actually a gear optimized upper chain growth. About 10mm at 50T Cog and close to non at 10T Cog It will have a 205x65 Trunnion Shock And 148 boost at the rear but we want to test with 49mm CL in front as our chain stay does not have to pass the chainring we have some freedom here to try tthings out.
