[RBW] Re: Need Help Diagnosing Weird Handling on my Atlantis
Yes, a bent steerer tube could cause symptoms like this. That's why I asked whether Waterford looked at the blades, or the steerer, or both. It's possible, if they were told to align the blades, they may not have looked closely at the steerer (though it would have to be a bad day at the office.) I have successfully straightened a bent steerer. They can also be replaced. Certainly the OP is not going to discard an Atlantis.

This is all really great advice. Thanks, everyone! I'm certainly
frustrated, but I also feel like I'm learning something new about bikes.
Your wisdom is appreciated.
Andy, the headset was not replaced. You ask great questions about the work
they did, and unfortunately, I don't know the answer. I'll probably reach
out directly to Waterford to learn more about what was actually done.
The plan is:
1) Get more info from Waterford
2) Replace the headset.

A bike that required frame and fork alignment from a front end crash
deserves a new headset.
Hopefully just an unstated part of all the work performed on your bike. I
can't imaging clamping up a bike frame for cold set adjustment at a frame
table with the pressed headset parts installed.
Was the head tube re-prepped ("gaging" if no material removed?) prior to
pressing the cup, race? Hopefully just assuring that the tool moves into
the ends of the tube without slop or bind, and the mill faces quickly
verify the ends to be parallel prior installing a fresh headset.

Tires inflated and beads set properly? I know its like asking “Is it plugged in?” when troubleshooting, but this can cause squirrelly handling. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

[RBW] Re: Need Help Diagnosing Weird Handling on my Atlantis
I don't know a lot about this kind of thing, but I imagine it would take quite a lot of force to knock a head tube out of alignment. Usually the fork will go, then the down tube will ripple before anything happens with the head tube. When you say the fork was realigned, was it the fork blades, or the steerer tube, or both? I agree that checking the head set makes sense--be sure the cups are seated correctly, bearing retainers are properly oriented, etc. I don't think an out of true wheel could cause these symptoms--at least not one that you can still ride without it hitting the brakes. But perhaps the axle got bent or broken in the collision? Some of the handling issues sound similar to "indexed steering," or what could happen when a headset gets brinelled. I'm not sure how that could happen due to a collision, though. It usually happens over time.

My suggestion for "eyeballing" it (my fork was off enough that it was visible) is: 1. Sight with one eye down the front of the head tube and, perpendicular to that axis, line up the front "shoulders" of the fork crown with the fronts of the fork ends. They should line up nicely. If one is well forward of the other it will be clear. 2. Pull the handlebar stem out of the steerer and sight down the inside of the steerer. (If you have a fender installed, that needs to come out, too.) The center of the tire should be right down the center of the steerer. If the forks are pushed to one side, it will be clear. To be more accurate, you can remove the tire and tube from the wheel. Of course, you should also check the dish of the front wheel and, as noted, make sure the headset is installed correctly. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
