The Point Adapter has a narrow clamp, which is very stable. Who needs a place on the handlebar extension will be well served. The support tube is adjustable - can thus be individually adapted. The installation on the handlebars adjacent to the stem clamp is probably the most sense. I have attached a speedometer and a Micro-light on the handlebar adapter. If parts are very good in view. For larger lamps there should be space problems. One or two centimeters more width would have been the carrier to shame. For my needs it fully serves its purpose. Use the metal reducers very well crafted it is to be mounted easily on handlebar diameters from 25.4 to 31.8 mm. All around recommendable.
