First Look: YT Industries TUES CF
In NZ the YT bikes are pretty close (~few hundred in it) in price to most of the Giants with similar specs. For example the capra CF comp has almost exactly the same build kit as a giant reign 1 and the reign is $5940 NZD vs the capras 5599 NZD. The glory 1 has an equivalent spec and the fork can be upgraded to match for $4300 vs the Tues AL comp for $4600. And you can walk into a shop and ride home on the giant without waiting a few weeks or months.

It really does depend on the design of the helmet and what impacts it is designed for and how the engineers have decided to deal with different loading cases (Moto will differ from dh etc). But yes if it flexes enough to contact your chin your chin may take enough of an impact to cause injury. In reference to the D2 I have seen a crash that snapped the entire chin guard off a TLD (d2 or d3 can't remember). The guy walked away uninjured and continued riding in a different helmet. So different method same result really.

Yea they are generally quite flexible on a downhill helmet. Allows for energy absorption in the deformation without permanent damage to the helmet. If you grab something like a fox rampage you can easily flex the chin guard by hand. That will be a 1.6m+ drop test onto the helmet. http://www.bhsi.org/stdcompsum.pdf is the drop test heights. In the tests where the helmet is dropped it contains a headform (ranges in size and weight (5-7ish kg from memory). They measure the acceleration from the headform and compare it to the standard.

Pinkbike Poll: Oval Chainrings?
Ive had many an oval 26" wheel. They are truly over rated.

Gloworm X1 and XS Lights - Review
100grams on your head is a lot lot nicer than 330. Those battery packs are heavy! and you notice them on a light open face helmet

Gloworm X1 and XS Lights - Review
The gloworm X2 is a good middle ground at 1500 and plenty bright enough.
