By the way, I build forks and the term used by all parts manufacturers for the pictured part is "dropout". The slot orientation has nothing to do with the fork axle offset, which is erroneously referred to as "trail" by many in the cycling industry. .
Thanks for the info! Which suspension forks are more durable, coil or air?
