Do new wheels have a "break-in" period?(5 posts)

Do they typically need to be retrued after ~200 miles?
yes, it comes just before the break-up periodmr_spin

Perfectly built wheels should theoretically never need to be trued. Well built wheels should not need retruing after 200 miles. 5,000 miles, maybe. 10,000 even better.

Either you are riding into big solid objects far too often, or you have some badly built wheels.
if not properly stress relieved, yes nmgtx

In a perfect world, I would say no.Quack

It is true that with a perfectly built set of wheels, you will probably not have to touch them for thousands of miles. However, even on well built wheels, it is not uncommon to have a random spoke lose tension slightly within the first few hundred miles. It seems that no matter how evenly you tension and pre-stress the wheel assembly, or how carefully you apply spoke prep and verify that no spokes are twisted, riding on them always seems to make the components shift slightly, spoke elbows into hubs, nipples into rims, etc. If you go through your wheels once after a few hundred miles and verify that the wheel is still round and uniformly tensioned, it should go for thousands of miles without trouble.

Depending on the type of rims that you are using, they may be extra sensitive to slight tension differences. The lighter low-profile race rims are usually much more affected by slight tension differences than the stiff aero-profile rims.

While proper stress-relief catches a lot of potential problems, you'll still have spokes settling into flanges, alloy nipples settling into rims, and perhaps rim stresses being relieved. Small changes all, but they do add up.
I like to go over my wheels, new or not, once a year, just to check spoke tension, catch any problems, and get them all trued up for next season.
