Bike is VERY sensitive.....

You can follow my build at https://www.bikeforums.net/bicycle-m...ld-thread.html
Now that I have it built it is crazy sensitive to steering inputs. Almost scary to ride. Not much on the geometry has changed other than the front fork, but that was minimal.

Going by the build thread; OP replaced a suspension fork on his Schwinn hybrid with what I think is a "standard" road disk fork (not suspension -corrected). There was also a change in handlebars / stem as well.
Could totally result in significant changes in geometry/ handling; esp since the spirit of the build was " A Frame is a Frame, and a Part is a Part, and I'm not going to let the naysayers get in my way "

Aaron, without examining the bike itself I would guess that you have the preload on the fork headset too high. If you lift the front fork and tilt the bike one way and the other, the front wheel should fall back and forth smoothly. Also another possibility is that the preload on the headset bearing is too low. Hold the front brake on and push the bike back and forth. There should be NO clicking. The headset preload in either case would make the bike dangerous to ride and is the most easily improperly set adjustment by beginners. You loosen up the stem and then loosen the preload on the top cap Allen head screw and then you tighten it only until it stops clicking when you hold the front brake on and push forward and pull back. There should be no more play without overtightening. You then make sure the stem is facing dead forward and tighten the locking screws. You have to do this immediately. If you ride the bike with the preload too high a crash is a likely result.

Looks to me like you did a great job first time around (with the understanding that I only have pics and your descriptions). Just from pictures, you may be a natural bike mechanic. I think some folks here may just be a bit envious/jealous/had their sense of superiority questioned. I’m sure you have stuff to learn but you made a great start.

I will tell you that I love it, other than the damn bars!! My new ones should come today. I rode 5 miles yesterday with my hands laying flat on top of the brake levers to keep my hands in a decent position. Why would anyone choose to ride with their wrists swept in like that? I am miserable until I get new bars and can actually enjoy riding. The forks are great. I like the angle. I am still confused about the person that said my stem was backwards. What?

Hard to say from the pictures, but it looks like you’ve got your bar installed so that the ends of the grips sweep up; most of the time, that sort of bar is installed so it’s flat across the top, but sweeps back towards the rider.
There’s a lot of things, like how high or close you have your bars set, that would also contribute to what sort of width / sweep works best for you. Also, everyone has different preferences and physiology; that’s why there are so many different handlebar shapes out there

Bars can be tricky to get right, especially when you’re picking them out from a catalog, and you have to guess how they’ll fit.

EDIT: Oh and yes, I don't have a big bike store near me to go look at parts and things. We have a few small bike shops but they are mom-and-pop stores that cater to retirees and their beach cruisers and tricycles. They looked at me funny when I asked if they had a 9-speed chain in stock. I pretty much have to get everything delivered or drive an hour down to Myrtle Beach to a bike store that still doesn't cater to younger active people.

It is the backsweep angle on these bars that are bothering my wrists. They force me to turn my wrists inwards. I have wide shoulders and need a bar with very little backsweep angle. Yes, I have turned them down more from what you see in the pictures which helps some but the bars just aren't wide enough and that backsweep angle is not good. I should have new bars today so I will see what I think. They are 800mm which I think is going to be too wide but I will try them out and cut until I am happy.
By the way the saddle and the bars appear in the pictures, that seems like what you’re trying to accomplish.

My son has wide bars on his MTB. Feels totally bizzar to me. I have way less control with my arms three feet across in front of me. I'll take my 64-40 Cinelli Giro d'Italias any day.

The bars appear to be rotated up (like a V) in the photos, when they need to be rotated about 70 degrees so the sweep points at the saddle, not the sky. That's why the OP's wrists are rotating inwards.

I’ve done some single track portages with my Bridgestone when it still had the Sakae Road Champions on it; no thanks, not anymore. If I’m going off-piste, I’ll use the widest bars that’ll fit between the trees.
aaronM46 : here’s my “Kruizer” with a 790mm moto bar, for reference
That, and this bike is the antithesis of what SMD4 considers a bicycle to be, though it does have rim brakes

Ugh. 40cm bars feel like I’m doing “diamond” push-ups. 45cm Cowchippers are my go-to bars for the road bikes.

I was riding bikes before the Repack gang developed real MTB's and the only improvement in the ride was suspension and that came at the expense of weight. There is a little local bump that is 20% and with a normal road bike I could never get more than 3/4th of the way up it and would have to push the rest of the way up. I got a Trek HiFi (or whoever (Bontrager?) built it before Trek) and made it to the top. But this was only because it was heavy as hell and had a long wheelbase so that I could stand on the pedals without the front wheel coming up.
So there is very small differences in geometry of any bicycle and it is only because with this geometry you can ride with no hands for a short distance. Please don't come back and say that you could descend Le Alpe du Huez with no hands.

The default position of a suspension fork is the same as a road fork. So unless you're compressed or rebounding past zero, the rake and trail are pretty much the same. If you completely turned a fork like that around the bike would still be ridable. High wheelers had no rake or trail. but the vertical head tube and the bends in the fork blades. Do not think that a bicycle is a complicated machine. While modern bicycles handle slightly better it is not by a lot. Italian builders tried everything possible to improve bicycles and the difference can hardly be felt. The French had large rake and trail and the bikes handled a bit more smoothly but Dutch commuter bikes have the same geometry.
