Precision CNC machined, engineered details available here, from Prototipo Works:
Presta to Schrader Valve Adaptor.
Perfect riding kit addition. Extremely handy to have. Converts Presta (French) valve threads to Schrader (Auto) valve threads. Making it possible to use auto gas station air pumps if caught without a pump.
Alloy Presta Valve Caps.
Strong lightweight, functional finishing details. Fine finishing touches for all Presta (French) valves. Protects against ingress and debris and also if used with spare tubes bundled ready for use or in your jersey pocket without a valve cap, can protect against accidental valve self puncturing.
Under Flush Bidon Cage Boss Blanks.
Neatly blank off those unused bidon cage mount holes. Helps stop mud and debris from entering your frame through those open, unused mounts. A perfect finishing touch for your frame if you're creating a clean bidon cage free look.

Ultra Low Bidon (Bottle) Cage Bolts - TYPE C 7.9mm Head.
A NEW small batch addition to our lineup.
A few of you kindly asked for something smaller, something in between sizes, for something that sits neatly on top and crowns the less common narrow bosses that protrude a few mm up from tubesets.
Because of the reduced head diameter and clamping area the use with bidon cages and accessories is NOT recommended, this is purely a neat alternative finishing, crowning detail.
Leveraging the best qualities of our new Ultra Low TYPE C 9.0mm bolts these new smaller 7.9mm heads are now also available in a set of 4pcs, precision CNC machined from Stainless Steel, polished, laser etched and finished with our PVD coating.
