Muc-Off
Say goodbye to the hassle of traditional tubeless valves that clog up and require valve cores to be removed to fill sealant with sufficient air flow during set up. Big Bore Valves are engineered with precision and designed to deliver maximum air inflation simply and efficiently. Crafted from 7075 aircraft grade CNC machined aluminum construction with a stainless-steel ball valve, this fully serviceable valve is built to withstand the toughest rides, whatever the conditions. This patent-pending design sets a new standard in high air flow tubeless tire systems with a revolutionary ‘Straight through’ internal design for maximum airflow fire power, allowing higher air volume per pump, reduced sealant clogging and easier tubeless setup.

Lock was cut and bike stolen the third time I used it.
I needed a new battery was told by another Specialized bike shop. It was a generation one battery so I just ordered it online and when it arrived, it was the wrong battery. When I contacted them and told them what happened they gave me the correct battery to order and accepted to return and also gave me my 15% discount for my first order. Hello gladly do business with the shop again.
The product description does not list the size of the thread end. Upon receiving the product, I noticed the threads were not a standard air hose size. They are smaller. I have to find some sort of adapter to go from the Presta inflator valve to my air hose.
Easy install. Went from 170 to 165. So far so good. Can’t say I noticed anything dramatic with the 5mm difference.
Makes switching chainrings very easy… although you do need a specific tool for the job.
