Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Muc-Off Big Bore Lite Tubeless 70mm Valve Stems in Black

Brand:Muc-Off

Code:21450

The Big Bore Valve range is engineered with precision and designed to deliver maximum inflation simply and efficiently.

This patent-pending valve sets a new standard and is the benchmark in high air flow tubeless tyre systems with a revolutionary ‘straight through’ internal design, which means no clogs and maximum airflow fire power. Featuring a cutting-edge, integrated ball valve system, the valve ensures lightning-fast airflow, turbocharging the sealant filling process. Say goodbye to the hassle of traditional tubeless valves that clog up and require the valve core to be removed to fill sealant and achieve sufficient air flow during tubeless set up.

Muc-Off's Big Bore Lite offers up to 230% higher air flow than traditional Presta valves thanks to the straight through bore design. With the ball valve construction and integrated lever, you can quickly open and close the valve for effortless airflow control, and even fine tune your pressure whilst you're out riding. Crafted from 7075 aircraft grade CNC machined aluminium construction with a stainless steel ball valve, this fully serviceable valve is built to withstand the toughest rides, whatever the conditions.

Experience no clogging, simplified tubeless set up and maximum airflow with this innovative coreless valve with integrated stainless-steel lever operated ball valve system. The straight-through design delivers up to 254% greater airflow than Presta valves, supercharging tubeless set ups and getting you back to the action fast. The integrated lever opens and closes the valve for micro-adjustments to pressures whilst you’re riding, so you can adapt to changes in the terrain or conditions.

Featuring a universal valve head that’s compatible with most screw on and push fit pumps, as well as a 4-way tyre insert air flow base that’s compatible with most tubeless inserts. With spanner flats on the head, lever and body, this valve can be serviced and maintained to last for years. The coreless design means you can check sealant health through the valve with the Hey Dipstick! (sold separately).

Features:

  • Precision machined sealant level dipstick
  • 4mm machined hex key slot for easy installation and removal
  • Supplied with various rubber bases and O-rings to optimise fit and seal with multiple rim types
  • Bespoke spanner specifically designed to tighten the big bore body during installation and removal
