hey guys-

Searched around but didn't find a lot on this. Anyone run the adapter that lets you use your own stem and gets rid of the knock block system? What happens if you crash? Does it void warranty if you use the adapter if the frame gets hit/broken?

Been thinking about getting one for ease of use with a tailgate pad as well as having the freedom to run any stem I want. But if it's a bad idea and can void a warranty I might not. Any insight appreciated.

I am not running one, but from my understanding running the adapter keeps the knock block system in place when you're running a non-KB stem. So it wouldn't make the tailgate pad easier or anything, or void any warranties, as its keeping the KB.

Looks like this thread has info about it:

Oh ok thanks. Just saw that and realized you're right!

Have one on my 2018 Remedy, which is about to be migrated to a 2019 Remedy and used it since August 2018, never given me one ounce of trouble. I run it with a Truvativ Descendant 35mm stem, and have never had the adaptor move. Granted I’ve never had a full blown crash on it (not exactly planning too either) but despite heaps of riding around my local trails, and two trips to New Zealand’s bike parks, it’s never creaked or come free when the bars have swung round. It’s an offical trek part so I doubt it will void your warranty should it come loose. Do remember that even using the knock block stems, the system still relies on the frame chip, which if the crash is hard enough it will break the chip and impact the downtime protector anyway

Only fault of the adaptor, bloody thing cost $60 Australian Dollars.
, but ehh I’d rather have the adaptor than not

I’m running a race race stem and wolf tooth spacers with zero issues with knock block. I don’t even thing an adapter would be needed or wanted.

Perhaps to prevent the damping controls on the top of the fork from getting damaged from running into the down tube?

The folk still stops with the knock block.

I'm using one with my Renthal stem, no issues with it.

It's recommended to still run the adapter however.

Only the friction in the spacer stack is what's stopping it. If there's a lot of friction, the headset is likely too tight.
