Though Presta valves are just about commonplace on higher-end bikes’ wheels, the issues positively do have their drawbacks. Dutch firm BBB Biking has determined to do one thing about that, with a li’l Presta-improving machine often known as the CoreCap.
So to begin with, there definitely are good causes to make use of Presta valves.
Amongst different issues, they’re higher than Shrader valves at sustaining excessive air stress, they’re lighter, and so they’re narrower. And since they’re narrower, the holes which are drilled within the rims for them are smaller, and thus much less prone to compromise the integrity of slim highway bike rims.
Moreover, their cores can (normally) be eliminated, permitting sealant to be injected by them into tubeless tires.
These cores, nonetheless, are annoyingly fragile – they ceaselessly get bent and even snapped proper off, plus they’ll can turn into clogged with sealant. Moreover, Presta valves require a particular Presta-specific pump head or adapter, leaving cyclists out of luck in the event that they unexpectedly must inflate their tires someplace like a gasoline station.
That is the place the CoreCap is available in.

To make use of the fundamental Improve Set model of the machine, you simply take away the core of your present Presta valve (and sure, it should have a detachable core), thread the machined aluminum CoreCap onto the highest, then begin pumping with a regular Shrader-head pump. The CoreCap then stays on there full-time.
Not solely does the unique valve retain all of its unique Presta promoting factors, it reportedly additionally beneficial properties 300% extra airflow, and it loses all of its core-related fussiness and fragility.
As an added bonus, due to the elevated airflow, BBB Biking claims that use of the CoreCap ought to make it attainable to seat tubeless tires with out the necessity for a compressor or CO2 cartridge.

Talking of which, there’s additionally a fully-integrated Tubeless Valve Set model of the system. Pricing for it begins at €29.95 (about US$35), whereas the Improve Set – which incorporates two CoreCaps – is priced at €16.95 ($20).
Cyclists who’re uninterested in their Presta valves may also need to try Schwalbe’s Clik Valve, though it does require its personal particular pump head.
