Thats awsome, Preety good going for a new frame on the market! There cracking looking frames, I would love to own one, but alas, being to tall has its downsides. Good luck with them Steve! I'm sure you'll get nothing but good feedback from these! Love the idea of the mounts, too! Just a thought, is the bottom 4 bolt mount, too low for a V lug? If not, could you have a sort of 'combined' mount? Where its a 4 bolt mount, but has the traditional V brake 3 holes for the spring tension on the inside? So all you'd need to do is screw in or unscrew the lug for swapping the brake over? Eitherway, the current setup looks like it has no downfalls, was just a thought.
