again, i would like to say that i really happy to see someone make a frame. my comments are only said to try and point him in the right direction, and not just being stuck up and being as ass.
first off all, the pivot point is really high. there is going to be an insane amount of chain growth. basically when you go over a rock garden, you are going to feel a tugging on the cranks, because of the chain growth. and it will stop the suspension from doing its job when it hits bumps, also when you pedal it wont track the ground well.
i have no idea about the leverage ratio or the travel on the bike, but following the geometry of the v10 isn't the most ideal. the v10 is actually quite high bb wise and steep on the head angle. that is fine for the v10 because it uses 40% sag. the problem with this bike is that the suspension will be very linear and doesn't have the ramp up that the v10 has. so if you run the right amount of sag to get the geo working nicely, the bike wont ride that well and keep the dynamic geometry in a good position.
geometry isn't a big deal, until you start pushing the bike really hard, this geo works fine. just could be improved slightly. after all, its the small details when added together that make something amazing!
but seriously, good work! i can talk about what is not ideal, but whatever its just talk. he made a frame and has done what no one else has. so props to him!
