Tony Foale experimented with steering rake using tellies. Each time he steepened the rake, the better the bike steered. The last experiment used a vertical steering head. But when he braked, he got an unholy judder. I went one step further with a negative rake. It steers lovely and there is no dive, and no judder on the brakes. If you can't join 'em, beat 'em.
