Need help w/ buying decision è HED3 vs Jet60

Front Hed 3 will be true or not true out of the box. It will not change unless you crash it. The rear may have a bit of play due to some fun with cassettes but otherwise the same will be true.

Some folks claim the Hed 3's are a bit flexy for them. I am using an old specialized in the rear and I think it moves a a bit more than a spoked wheel would, but no issues in the front, all anecdotal.

If you really only do flat and not very windy TT's, you should consider the Hed 90 for the front.

Fair warning, in windy conditions (depends on your comfort level) or with less rider weight, even a Hed 60 or Hed 3 is a handful when on TT bars.

I have several H3's, right now I wish I had Hed 90's and 60's, but I get most of this stuff of EBay and H3's were a bit easier to get.

The stingers are much better than the jets-stiffer and lighter. The 3's are more aero than the 60,s though, but flexier. The 90,s are more affected by sidewinds than both though. If you are light use the 3 spoke front and back. if you are heavy use a stinger 60 front and 90 rear.
