[QUOTE=63rickert;20720392]Safety issues:

Braking. If rim brakes, and especially dual-pivot rim brakes, it just ain't working right off-center. Brakes are a primary safety system, brakes need to work.

Agreed that brakes are #1 . If you can't stop you better not start. But there have been millions of off center wheels on bikes that stopped well enough to never be a problem for riders. The usual situation of a dual pivot brake caliper acting on an off center wheel (and I might say it is the brake that is off center since it only needs to deal with the wheel) is that one pad will contact the rim first and tend to push the rim over to the second pad. this generally makes the "feel" a bit mushy but there's no change in the leverage or re tard ation force the brake has. In fact many disk brakes are designed this way. With only one pad moving. So I see this claim as a false concern.

Quality control. If QC is so bad forks 2mm off get by there are lots of other QC issues with that fork and with that frame.

Sure, But that's not the OP's question. Note in my earlier reply I did allude to this though. IME and given the number of slightly off forks/frames I see and the lack of other problems (like structural ones) I don't make the "If A then B" jump as my default. I don't think the OP's sky is falling.

This bike is going to pull to the side and it's going to pull to side strongly under braking.

Maybe. But that wasn't noticed enough by the OP to mention it. A significant number of bike's I ride (and this includes the after service test ride) have some degree of body lean tom no hands straight. When hands on this is not noticed except for the worst cases (and 2mm is not anywhere near worst case). As to the braking on a bike with a off center fork I can't say much because I don't think I have ever noticed this. Now on a multi track vehicle (like a trike) certainly so.

Aligned frames ride different and better than non-aligned frames. It's carbon, so we're supposed to just accept that everything is wonky?

I agree that balanced frames ride better just not in the ways that you seem to be concerned about. I also agree that a symmetrical rider rides better then one with a long leg, A shortened clavicle. A dominate side. I could suggest that the bike in question might be better aligned then the rider is "Wonky" is a relative term. Bikes are mass produced products, usually controlled by that bottom line Cost. Thus manufactures all have a tolerance of what's passing and what's not. As I mentioned before this tolerance isn't typically made known to the public. I have heard of consumers stating they have been told x number or y degrees but to find this in official docs will be quite a challenge. So what's the rider to do? First is to find out if that 2mm is a problem in function. If they can feel it, if it hinders their ability to steer the bike. If it causes then to loose balance then the OP should seek a solution. But if the bike rides and handles as it did before (like when it had the other set of wheels, remember those?) then the function isn't effected. Should we accept this? Well many of us do whether we know it or not. When you have the tooling to measure alignment to at the thousandths of an inch you learn a few things. First is that every frame/fork is off to some amount. Second is that when you remove and reinstall that frame/fork on your alignment table (or machinist flat surface in my case) the offness you measured before changes a little bit. Third is that some miss aligments are more important the others are. Lastly is that the bike is a system, other components are often enough not perfectly dished, symmetrical or square.

What the fork and wheel combo (again remember the wheel?) are, alignment wise, is one thing. Your claim of there being unsafe conditions is another. Can you give us some backround on your expertise to feel good about making this claim at such a long distance? Andy
