Review on 🚲 Bike Bits Presta Valve Adapter: Effortless Presta to Schrader Conversion + French/UK to US + Easy Inflation with Standard Pump or Air Compressor by Johnathan Sherman

I'm not a big fan in general. The problem is that the wall thickness prevents the compressor pin from pressing against the valve stem. Granted, both of the ones I tried were made for Auto Schrader valves, but isn't that the point of an adapter? I was able to fix the problem by re-drilling the center. After removing just a fraction of a millimeter they work perfectly. Wouldn't buy again. *** My Rating Criteria *** Build Quality (47.5%) - 3.0 Star Efficiency (47.5%) - 2.0 Star Customer Service (0.0%) - n/a Packaging/Presentation (5.0 %) - 4.0 stars WEIGHTED AVERAGE (100.0%) - 2.6 STARS
