My name is Luis Arraiz, I am a frame design engineer and specialize in bicycle vehicle dynamics, kinematics and geometry design. I was the founder of K9 Industries Ltd in 2005 in the UK. I worked at CSG (now Pon) from 2015-2023 where I was responsible for the geometry, kinematics and packaging for all the full suspension bikes both analogue and e-bikes for both Cannondale and GT bikes and also several GT hardtails. I introduced the concept of size specific geometry and kinematics for Cannondale dubbed “Proportional Response”. I am now back to the UK, where I am a senior...

@Cascade, Have you done much/are you happy to comment on any testing you've done regarding the tuning of AR on a bike, and how it interacts with suspension/shock setup? I agree with you in that I prefer high AR bikes, but I find that a high AR bike will expose a lot of flaws in suspension setup... Slow or unbalanced damping, rampy air spring, excessive sag, all feels much crapper on a high AR bike. I've designed a bike that I have yet to complete, but what I (think I) have learned from riding lots of different bikes is that...
