Nowt wrong with being a geometry geek – I’ve been doing the trial and (mostly 😉 ) error thing for years . . . currently slack and super-short is in favour.
makes sense looking back – the longer chainstayed bikes (Kona Coiler, Intense Uzzi, On-One 456) were the best dhers.
. . . oh, and the Kona Five-O 😛
. . . and on reflection, my current ride (Commencal Absolut SX) and the little short-stayed Dialled Holeshot were definitely the most fun in the twisty stuff.
