Eurobike saw Muc-Off showcase innovation for riders using tubeless with the introduction of its new Big Bore Tubeless Valves.
The brand has reportedly spent three years developing the new patent-pending range of ‘Big Bore’ Tubeless Valves – creating a high airflow tubeless tyre system with a simple mantra: “Big bore + No core = Extreme airflow”.
With its ‘Straight-through’ internal design and cutting-edge integrated ball valve and lever system, the valves boast an airflow rate that’s up to 254% higher than traditional Presta valves.
Big Bore Tubeless Valves are:
- Offered in four different stem lengths – 30mm, 35mm, 45mm and 60mm to suit a range of rim depths
- Available in Big Bore Lite, Big Bore Hybrid, and Big Bore Ludicrous (3.3mm, 5.7mm, and Schrader rim hole compatible, with a 5.7mm valve stem and 5.7mm valve head)
Setting up tubeless, seating tyres, is often dependent on a high flow rate. It’s here that traditional Presta valves can have some serious limitations: Restricted airflow, and sealant clogging, all making for a time-consuming tubeless set up.
Although Muc-Off believes that their current precision Tubeless Presta Valves still have a vital role to play, mainly in road and XC (for those who prefer ultimate weight saving over convenience), the Big Bore Tubeless Valves range will likely appeal to riders running a rim and tyre combination that requires a substantial airflow hit, with the least amount of hassle.
Big Bore Tubeless Valves aim to simplify inflation, and the sealant filling or top-up process, reshaping tubeless with enhanced performance and convenience.
The new valve’s straight-through internal bore design means no more sealant clogging or removing valve cores during sealant filling, making tubeless repair and maintenance simpler and easier than ever before.
Crafted from lightweight and durable 7075 aircraft grade CNC machined aluminium and featuring a unique stainless steel coreless ball valve and integrated lever, riders can quickly open and close the valve for effortless airflow control, as well as fine-tuning tyre pressures on the move, particularly useful for those riding on a range of different terrains.
On launch, Alex Trimnell, CEO at Muc-Off said: “Our new Big Bore Tubeless Valve range is a game-changer. We’ve known about the limitations of traditional Presta valves for years, and we knew we could design a better solution.
“Our ambition here is for our new valves to become the globally adopted standard, so it’s imperative that they outperform traditional valves in every way.
“Following years of extensive testing and development, I’m stoked to say that they do! We can’t wait to start seeing them on rider’s bikes so they can experience the future of valve technology for themselves.”
- Muc-Off’s Big Bore Valves are Insert compatible with their four-way airflow base; they are push-on and screw-on pump compatible and can be used with a Muc-Off Secure Tubeless AirTag Holder.
- They are also simple to install and remove due to their 4mm machined Hex key slot.
- The valves are fully serviceable, with Muc-Off offering a Valve Servicing Kit (Available later this year), to help riders easily extend the life of their valves and maintain peak performance
