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!
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 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.
Brand:Silca Aeromind Llc
Code:TUBELESSVALVEKITBLK
Most carbon rim profiles require valve stem lengths longer than what is typically referred to as standard. Those longer valve stems have significant weight that can unbalance the wheel at high speeds. SILCA Threaded Valve Extenders are lightweight aluminum that provide a significant weight savings over a full-length brass valve stem. The SILCA extenders come with SpeedShields and spherical nuts that protect the rim, prevent rattle and improve air flow.
SPECIFICATIONS: High precision CNC machined Aluminum Valve Extenders with full external threads Knurled spherical nuts to eliminate bending load on valve stem Custom molded silicone shield with 3M adhesive backer Less than half the weight of brass valve extenders SpeedShield Improves wheel aerodynamics up to 0.5 Watts at 30mph
