What the hell has happened to the DD?

[CaNsA]

I'm lid shopping, and many of the lids I like all have one annoying "feature".

Why are all the manufacturers opting for this type of fastener instead of the much loved double-d?

I like the quick release style, you get the exact same fit everytime, no messing with too tight or too loose.

I've got helmets with both styles though and I don't mind either.

I don't miss the raggedy ends on the straps and they are less prone to getting beard hairs trapped in them.

Pretty sure Arai and Shoei still use DD.

EDIT: I stopped worrying too much about helmet design and fastening systems some time ago. I want them light, non-intrusive, quick to put on and comfortable. I don't believe they make a great deal of difference in a crash anyway so I want them to be comfy and easy to see out of above all else.

Those ratchet things are convenient and easy to take off with cold fingers. I've been stuck in my helmet before today with a DD ring setup and cold fingers.

Shark Speed R has DD as does HJC RPHA.
Have one of each.

I much prefer the ratchet style, 2 clicks and I know my strap is done to where I like it and I can do it with gloves on rather than trying to fuck about with DD rings and poppers.

[supZ]

My new shoei has double D ring, wouldn't want anything else.

Racing still requires DD; other types just aren't as safe

Cork was good enough for helmets in Nineteen Dickety Six, I don't see why we needed to change anything.

Double-Ds have sagged in my estimation. Seatbelt-style is inflexibly clunky-and-clicky.

I wouldn't shove my head into anything other than Micro-Metric ratchet now.

The ratchet type straps have all the advantages of the D, with all the advantages of the seatbelt type. I like them.

ACU still demands DD in most forms of sport.

My so last season Schuberth S2 has one of those ratchets, the newest version has gone back to the DD's. Apparently some track days don't like the ratchets and insist on the D rings. Meh.
I got used to D rings on my old Arai and the ratchet did seem overly fussy at first, but I now find the ratchet quicker and less fuss than D rings.

I wouldn't worry about it, you'll get used to it soon enough.

[pompousporcup...]

personally, i preferred the clip type which i had on my old Agv. my new agv came with the DD type which took some getting used to.

quicker to put your lid on with gloves on

[waffles]

I really hate the DD on my Shoei, much prefer the ratchet on my old Shark.

I like using the D's to lock my lid to my bike.

Plus it feels safe, I'm pretty sure it's impossible to just work its way loose in the even of a spill.
The ratchet/clip type seem like they could come off if caught on a piece of the bike.

had a crappy BOX with the ratchet type, changed to agv with DD - took some time getting used to but prefer it for fit and in my mind feels safer as the ratchet could possibly snap with force? althought that force may probably also snap your neck

[chickenstrip]

Always been a DD man myself.
Used to get quite a few ratchet types returned where the springs had weakened, allowing the the strap to just fall out of the locking mechanism when I worked returns. Maybe just the cheaper helmets, but the systems all looked pretty much of a muchness to me, whatever helmet. Still, plenty of folks seem to get along ok with them.

As said previously, HJC RPHA10 is quite a good lid, and uses DD, assuming it fits you ok. Top vent has just broken on one of mine though

I had a ratchet type on my last lid, you get used to them and they're pretty good. Currently have a double D ring which is my preference, but not by much.

The seatbelt single click type are crap. The Mrs had one and it slowly slackens over time (ooer)
