[MTB gear] A Stem Riser to Raise Your Handlebar Height

I installed a stem riser from Deemount, trying to keep it from coming loose while riding.

There are many types of stem risers at Aliexpress, but all of them including mine are not suitable to be used in MTB riding. For me, my stem riser is working fine in my usual logging trail riding.

Is that the same as carbon assembly paste (contains gritty particles)?

As long as I know, normal carbon assembly paste contains pumice particles, whereas anti-slip liquid/paste usually contains metal particles. I don't know how effectively the former would work on metal against metal surfaces. In general, this kind of paste/liquid, whatever particles it may contain, won't have any decisive effect. The key is the highest possible torque that can be achieved in a given condition, I think. Thanks for watching!

OMG! DO NOT USE THIS FOR ANYTHING "MOUNTAINBIKE" !!!!!! I Would not even feel safe with this BS on a granny-bike. Buy a proper riser-bar instead, if you cling to your life.....

I clearly mention that this kind of stem risers are not suitable for mtb riding in the description. Any sensible gravity rider would stay away from this, yes. But some casual riders who just potter around mountains may find it worth a try to raise their handlebar height more than a couple of centimeters. Have you watched through the video? It clearly shows why this stem riser doesn't work in the first place. I tried to show how to install it in order to render it into a workable stem riser.
