Heh, kinda true
Sandwich's stem is so short I think it's making progress coming after him.

well, for me at least, mainly it’s just that I am 6’2’’ (not that tall!), so finding long enough reach up til recently was really hard. So a slammed 35mm rise bar (vs a 20mm rise bar w/ 15mm spacers) adds about 6mm of reach.
this is doubly important when you long-fork a bike, which both takes away reach and adds stack.
If I wound up on a too-long reach bike, I’d get a low rise bar and add spacers under the stem to shorten it a bit.
but anyhow, having a few eBay sniped bars and stems in the garage is good to mess around with til the front end is dialed.

Thanks, my Capra came with a 40 mm stem.
I'd throw a 50mm Thomson that I have on there right now, but the dang Capra has 35mm bar diameter, and I have glued on grips, etc.
I could use a tiny bit more room in the cockpit too, so I'm eager to try the longer stem.

Put a bell on it.
you can usually find the Raceface aeffect-r stems for like $25 on PB or Ebay. May or may not be the stem you want forever, but it’s a really cheap way to try it, and easy to flip again if you need/want later.
Just a thought.
thanks, this helps with fitting and stem length. I run flat bars and recently raised them via spacers, perhaps I should drop them or swap my riser bars back in. The reach on my bike isn't that long and it fits perfect when slammed, not sure I want it shorter. Is it really 16.9mm with 15mm of spacers? That seems huge but I'm way to lazy to do the trig on it. [edit did the trig and it's like 13.5-13.9mm depending on HA for 15mm]
So, while this helps with reach measurement and fitting, anyone gander a guess as to how it affects handling? or does it not? I'm always trying to quantify weird shit I feel on the bike, and his bike was like a circus bike- it felt weird as shit and you guys know the trash I usually ride. He had like a 50 or 60mm stem and like I said, maybe 20-25mm of spacers under it. Does pulling that reach back affect the hand to axle characteristic or something? Some aspect of trail?
We all know he'd have gone faster on a roadbike with 700x25s and drop bars if they'd simply bothered to tarmac his course down that that hill?
That, and ceramic speed jockey wheels. obviously
surely everyone with even a basic understanding of bike set-up lowers the stem/bar height when they do this?
Wait. What?
See calculator #4 HERE: https://www.analyzemath.com/Geometry_calculators/right_triangle_calculator.html
15mm spacers is ~13mm more stack and ~6mm less reach @ 65deg HA
Maybe I am confused, but wouldn't spacers only change the vertical z axis and not reach. Reach is a horizontal value, all spacers do is change the angle of reach and I am sure that would influence rider's perception of control inputs, I just can't see how the reach value would change.
if you had a 90deg head angle, yes.
Because when you have a head angle less than 90deg, the spacers are the hypotenuse connecting “X-reach” and “Y-stack”, forming a triangle.

There's just the two manners of vertical and horizontal to contend with. The wisest physicist will openly state they don't know why the laws of physics exist; a longer lever will always do more work.
The longer lever on the steer tube can stand the bike up in corners if energy has nowhere else to go. A shorter lever there will also require change to get the front wheel in the air - it's not the right rise stem and sweep of handlebars to compensate for giving up the ghost of frame reach measurements.
My Body Geometry Specialized gloves have 5mm of padding on one of the two pair. Should I get a 145mm stem on the Ridley when riding in these gloves??
This is what's wrong with the Industry - it's becoming too smart for its own good.

It's been a while, but yes I still have the "deathtrap". It's in storage, the old lady thinks its gone..
A longer stem also makes the bars shift side to side when you steer, at least at slower speeds. Offset shifts the front wheels contact patch to the outside of the turn, stem shifts your weight to the inside of the turn assuming a neutral riding position.
I've settled on a slammed 40mm stem with 41° offset fork. It's the best compromise of steering input and traction. A longer stem (45-50mm) give me the room I want, but numbs the feeling of what the front tire is doing....for me.
So do those little rotors on such burly looking tires and stuff. The seat also looks like its pointed to the ground...
Still waiting for my 50mm stem to show up from Chromag. Where the heck are you Fedex man????
Also purchased some Squarewave grips. Looking forward to trying those out.
Yetis are generally godawful builds ridden by newbs in my area.
My 1 day shipping from Chromag took 4 days. Might be worth calling them.
It ain't full Verdone until you put mineral oil into a set of Avids.
You want more?Listen to shirk!
You dorks have gone 'full verdone'

I'll admit that's one of the few things he's ever done that's actually informative and not flat out dangerous. Exactly what you should expect from dirt roadie in marin.......
But if you needed an engineer's draft to understand all the things that affect hand position, please do the rest of us a favor, sell your bikes to someone more deserving and go jump off a bridge.

Neat.BikeCad allows you to work that into your model.
Still making good progress on the latest rig?
Kinda ground to a halt. Hope to get back onto it soon as we have finally put together an organized family schedule. Last few weeks have been a mess.
I hear ya...
I know someone looking for a modern bike that would love that.so if your doctahawk reach is a tad too long, just add spacers, right?
