IDENTIFYING YOUR HUGO RIM AND SELECTING THE CORRECT VALVE STEM:
Stepped Hugo rims have a larger diameter valve hole on the interior of the rim, and a narrower hole on outside of the rim.
Quick tip: don't remove your tyre if you don't have to. If your Hugo rim decal reads:
MAX RIM PRESSURE: 2.8 tyres: 26psi, 3.0 tyres: 24psi
ERD 615, 622x49.9, 29 in x 52.3mm
Your rim has a stepped valve and is not compatible with this valve.
For "Stepped" valve hole Hugo use part AS0105 - Valve Stem pair, schrader, 32mm 14mm base.
