Presta valve rim adapter (drilled for Schrader) by aiber

Last crawled date: 3 years, 1 month ago

Based on the Wheels Manufacturing PSS-1, whose measurements are posted as follows:
Length: 11.4mm
Outer Diameter: 8.2mm / 9.3mm
Inner Diameter: 6.15mm
I guessed the flange to be 2 mm tall.
First print came out too small on the ID & the OD, but it worked for my rim which the last owner drilled by hand - unlikely to be the same size as a true Schrader drilled valve hole.
You may need to edit the IPT file to fine tune the diameters, or even the length depending on the depth of your rim (i.e. aero rims).
I didn't feel like printing it again, so I used a letter B drill bit to ream out the hole to size.
