Hello all,
I agree with Terence below on his assessment somewhat that main line manufacturers have downplayed quality for volume. One thing I must say is preparation and alignment is a quality issue. If it is not done there is no quality. I am certain that Richard Sachs and the other frame builders on this list spend a disproportionate amount of their time making alignment as precise as they possibly can.
It really should be job one and if it's poor no amount of aftermarket shop based tweaking will help. My daddy used to say ," No matter how hard you try son, you just can't polish a turd."
Any manufacturer of modern bicycles sold in bike shops certainly can afford the tooling for alignment and preparation. Without it their damn robots couldn't make them. While I agree the final check of quality should be the bike shop I don't feel that a shop should have any quality control responsibilities at all of a manufacturer anymore than my local computer store should have to check for short circuits in a display card they sell me. ( this can be expanded both ways so lets don't go overboard).
A manufacturer large or small should build a product that will perform as advertised to do the job it was designed for. While preparing and aligning a bicycle frame is a source of pride in many (mine too) shops a bicycle shop should not be expected to improve, perfect, remanufacture, or correct flaws in the construction of any consumer product. They should be expected when intimately handing a product to inspect it for flaws (rejecting the product as necessary) and in the case of bicycles or frames assemble them with a high degree of precision and personal attention. My humble opinion/
As Richard Sachs stated earlier misalignment is the (main most likely) of premature mechanical breakdown, human and component.
On the alignment issue, testing. I have an excellent alignment table and quite a few jigs and fixtures to do the job that needs to be done. To me its like truing and dishing wheels, I can perform as good a job with a jig and dial indictors as without. The difference is speed, a good jig is faster setup and I can true a wheel pretty well with my eyes closed with a jig. Lots of people own wheel truing jigs that generate poor output. An alignment table will speed an alignment job up but not necessarily increase accuracy or output. You cannot align a frame accurately without good tools, measuring devices and skill. An alignment table or jig is just one tool. It holds the frame steady.
String is (even my personal favorite-silly string) is of minimal value in aligning a frame. I have found even the frailest of dropouts (even Lambert) are to frail to manipulate with string. I don't even want to mention BB shells, hiatuses, statues or forks. My advice don't even try to align a frame with string, even wimpy ones.
Respectfully submitted,
Gilbert "silly string is my brand" Anderson

Shop time to prep a frame 1hr, plus wear and investment in tools. Mid size
and large builders simply can't justify the cost in time of full prep on
their frames. As the final word on quality it's the shops' responsibilty
anyway. Investment in tooling and specific knowledge used to seperate the
"pro" from the "family" shops. In my humble opinion big players in the bike
industry have downplayed the quality of performance bicycles to open more
sales channels and increase volume. This is a long term disservice to the
end users, as is often implied on this list many component problems are
because of miss alignment.
