NVO Components Engineering and Testing
NVO Components uses sophisticated engineering software to design products. All of our designs are engineered and optimized for material, cost, weight and other specific criteria. NVO Components products are then thoroughly tested both under laboratory conditions and by riders for feedback and to provide safety margins within the strictest standards. All NVO Components stems pass DIN Plus testing standards. You can ride and race in full confidence.
 

NVO Components stems featuring ATS technology have a distinct advantage over the existing threadless headset system. The problem with the current threadless system is that the ability to adjust your stem height is limited and requires a degree of mechanical skill. The ATS system corrects this deficiency and adds more benefits.

The current threadless system uses stack washers to compress the stem and preload the headset. If someone wants to adjust their stem height, they first have to loosen the headset bolt, remove the top cap, finally, loosen and remove the stem. Next, the appropriate amount of washers for the height adjustment needs to be removed from below the stem, then reinstall the stem, put the removed stack washers on top of the stem, install the top cap, preload the headset with the headset bolt, then tighten the stem. All in all, a very time consuming process. This needs to be performed every time a stem height adjustment is desired. Many bicycle riders don't even try to adjust their stem height because they don't know you can adjust the height, or they feel uncomfortable with taking their headset and steering components apart, or they just don't want to deal with the hassle.

The ATS technology replaces the stack washer setup with a single slotted shim. The ATS shim slides over the steer tube to preload the headset. The ATS top cap then preloads the ATS shim, this, in turn compresses the headset. ATS is a very simple assembly. The headset is now preloaded by the ATS shim and the NVO Components stem can be mounted anywhere along the ATS shim. Your stem height is changed as easily as your saddle height! You can change your stem height quickly and often, without ever loosening the headset. If you determine that you want to cut your ATS shim to a shorter length, please see the cutting instructions for the proper procedure.
