The USA's U17 National Champ Cruises Some Loamy Washington Trails

 He is built like me, long legs, short torso. Hard to get manufacturers to nail it for everyone. We all are a bit different.

 Layton is a lanky mofo

 The PNW has got a lot of them! The next generation is on fire!

 It's not the seat height that's the issue per se, it's that he runs his seat lower into the frame when descending (the video) than he does when climbing (the photo).
Indicates (to me) that either Kona's frames are too small, or FSA's seatposts are too short. Or both.

 @dkidd: Let's go with too short a post, ie: easy fix. Too tall a frame = 1990 bike frames all over again!

 @boxxerace: Remember that longer-travel droppers need longer straight/uninterrupted seat tubes to fit them.

 @dkidd: Oooohhh yeeeah, details are important! - Point well made.

 Thanks @bikes4kids !

 Merriam-Webster or Oxford? Which dictionary added it first is still up for debate.

 "In the USDA textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and humus than sandy soils, have better drainage and infiltration of water and air than silt and clay-rich soils, and are easier to till than clay soils."

Having lived up in the PNW and ridden there for years I'd have to say this is a pretty good description of most of the soil up there. There are of course variances, especially on the east side, but on the wet side "loam" is a pretty good descriptor. That and "duff". Lot's and lots of duff.

 @HsawAknow: Loam is a particular type of soil composition that's generally good for growing things (like the classic farmer's field). Duff is the mixture of plant/organic matter in various stages of decomposition on top of the soil layer - and then you have the litter on top.

None of these forest "loam" videos actually show loam, but they feature duff like nobody's business...

 @Lotusoperandi: I think Duff is more to the point. Most of the wet side is 6" of Duff sitting on clay.

 Less scientific, more how it feels. Soft, floaty, Loamy.

 @jeredbogli: I don't know about that. There are certainly areas of clay deposits (Vashon Island has a lot!) but what I found riding in the Cascades is more glaciated gravel till. Which makes for amazingly porous soils that drain well. Defying what you might expect given the amount of moisture the area receives, I was always amazed at how a lot of the trails would be wet but not muddy. Again, there were areas where it certainly was muddy, but there were lots of areas where it wasn't. Duthie is an example of a place where I was usually surprised by how well drained most of the trails were even though the amount of precip would lead you to expect much worse.

 @tablETeit: yes, but loam is a scientific classification for soil types that has been around longer than mountain biking. So those mountain bikers that happen to understand soil classifications rightfully take issue. Loam does roll off the tongue much easier, but 90% of the time freshly trails should be referred to as duff. But then all the Duff beer fans would be all worked up. There is no simple solution.

 Thanks, Ty!

 Fall City, WA. Even mentions it in the video . Look up "Tokul". Have fun!

 Tokul sucks, tell your friends.

 @caddydan: Friends, Tokul "sucks". You heard it here first. Sucks. Like horribly. Terrible. Just terrible.
