But, despite frames changing shape to be longer/lower/slacker, why are large frames still coming out with 20″ seatubes! Why not just give us ~17″ seatubes and beef them up enough to take 420mm posts.
Grinds my gears! Why does a 20″ frame need a dropped top tube and a seatpost brace when no one runs a 20″ post at max extension anyway, just make it an 18″ or smaller frame!
Well, the XL Kona Process 111 and 153 (and I suspect the 134, although I’ve not ridden it) have 18.6in seat tubes. Which, with the KS posts they come with, isn’t long enough for me. The new XL Hightower I’m testing has a seat tube over an inch lower than the Tallboy LT it replaces, and it’s on the cusp for me with a 150mm Reverb…
(here’s a pic of it with the saddle at full extension, just for you)
There are plenty of others. The Kona in particular was apparently designed with the impending (at the time) 170mm droppers in mind, but until they appear on the market us longshanks have to make do.
And I’m not the tallest, at 195cm or thereabouts.
