BBB CoreCap has reinvented the lowly bicycle tire valve with a design that enhances airflow, improves sturdiness, expands pump compatibility, and even probably sheds a little bit of weight. Their new CoreCap design is a mash-up up the 2 main tire valve choices – Presta & Schrader, and but it manages to keep away from the primary pitfalls of every. Much less probability of clogged valves with as much as 3x extra airflow from the identical skinny valve as earlier than. No extra fiddly valve cores getting bent by a misaligned pump head. No extra want for an extraneous valve cap. And but the CoreCap doesn’t look any greater than most Presta caps. Plus, full compatibility with any pump head that might connect to the standard Schrader automotive tire valves.
BBB CoreCap places a capless Schrader atop your Presta stem
In a nutshell, the BBB CoreCap is basically only a small alloy Schrader (AV) head that you simply thread on high of your current Presta (SV) stem, eliminating the tiny fiddly Presta valve core. By pulling the core out of the small diameter stem, BBB says their CoreCap will increase airflow by as much as 300%. And with the bigger area contained in the Schrader-sized alloy cap, that gave them room to create a spring-loaded, triple-sealed bleed valve that doesn’t want an additional exterior cap to maintain particles out and air inside.
If all of this seems to be slightly acquainted, you may bear in mind the bulkier Aigo-Tec Capless Pace Valve that we coated final summer time. However BBB independently developed what seems to be like a extra refined and definitely lighter resolution of their CoreCap. This new one apparently has a worldwide patent pending, and you’ll really purchase them now.


When BBB’s advertising instructed us they have been going to “blow your thoughts” with some new valve caps, I wasn’t overly able to succumb to the hype. I’ve tried a great deal of completely different tubeless valves and Presta conversions, and none have wowed me sufficient to vary my methods. Clik bought the closest to convincing me (and my colleagues) to transform, with its neat pump connection interface. However perhaps CoreCap may lastly be the one to sway me to essentially swap.
Are they definitely worth the swap?


That’s actually due to how painless the conversion was, and the way it kinda nonetheless seems to be like a daily valve cap ultimately. It took longer for me to seek out the closest valve core elimination software than it did for me to swap a Presta core for the CoreCap. (Why doesn’t BBB embody a plastic core elimination software with these CoreCaps, although?) You want lower than a minute to make the swap.


Sure, I’ve carelessly bent a number of Presta cores in my day, even damaged one or two. Some pump heads simply need to eat valve cores. Others annoyingly wish to take away the valve core itself whenever you unscrew the pinnacle. Plus, I’ve changed many over time, clogged by sealant. Clik solved the bent & unscrewed cores, however doesn’t deal with the sealant problem. I’d tried one other Schrader conversion years in the past, nevertheless it was heavy, clunky, and nonetheless actually wanted its personal cap to maintain dust out.


Now, I weighed a set of 4 CoreCaps and in contrast it to 2 units of Presta cores & light-weight alloy caps, and the CoreCap comes out 20% lighter. Certain, which means you might be perhaps going to avoid wasting 1g per wheelset right here. However all the advantages above and lighter sounds good, proper?
So how properly do they work?


I used to be in a position to rapidly and simply match the CoreCaps to each tubeless valves and common inside tubes with detachable Presta valve cores. Watch out to begin with clear valve stems, although. These little caps merely thread onto the skin of your current stem, and a small inner seal presses in opposition to the top to seal air in. If you’re like me and journey your bike in nasty circumstances with out caps over your Presta valves, possible there’s grit on them that might forestall an ideal hermetic seal.
The 300% airflow increase sounds nice, however does it matter? Extra stream doesn’t actually imply faster inflation. However there may be much less resistance, so the primary a number of pump strokes have been simpler than regular, and your electrical inflator may final a number of psi longer. It ought to even make seating a tubeless tire with a flooring pump simpler. However I haven’t wanted to do this but. The largest profit actually is that extra stream means a decreased chance of getting clogged by sealant.


What’s going to essentially be nice is broader pump head compatibility. All of my mini pumps and electrical inflators have both auto-changing heads or detachable guts to suit both Presta or Schrader valves. However many Schrader-only heads additionally exist, like these at fuel station compressors. And for the reason that BBB CoreCaps are threaded on the skin, you should use any press-on, clip-on, or thread-on pump head. That would definitely come in useful in a pinch.
Now, I simply must resolve what coloration caps I desire. And whether or not or not I need to commit to purchasing like 10 units of those little devices, and going all-in.
