Use Silca Removable Core Valve Extenders and avoid rattling with your deep-section rims
Silca Removable Valve Core (RVC) Extensions are smart in their design and are simple to install, providing air-tight valves without the use of tape or threadseal. The result: noise and vibration on the road are reduced.
That dreaded valve stem 'click' has troubled many a deep-section wheel rider over the years, often only discovered after about everything else on the bike has been rebuilt and greased; valve stem 'clicking' or rattling occurs when the valve stem moves within the valve hole in the rim, generally on rougher roads. Silca uses a patent pending ribbed gasket which is compressible to both fit more tightly to the hole as well as to cushion any contact between the rim and extension when the gasket is aligned with the hole, and if the gasket is located beyond the hole, it still provides critical vibration damping which can greatly reduce noise.
Silca RVC extensions solve air leakage due to poor thread fitment or to stem loosening by using both elastomeric gaskets at the interfaces as well as a thin film sealant on the thread surfaces. This thin film is non-adhesive so your extensions will be re-useable, but works to eliminate loosening caused by vibration or other factors. Silca RVC Extensions work ONLY on tubes and tubulars with Removable Valve Cores.
Note: The fitment recommendations given by Silca in the chart below are based on standard clincher and tubular tyre well depths - your rim may vary slightly. Some rims have deeper tyre wells, and some tubes may use other valve lengths. To ensure proper fit, you should measure the distance from inner rim face to base of tyre well. Valve stem, plus valve extension should measure 14-24mm longer than distance between rim inner valve hose and outer valve hole.
Locating the gasket within the hole is ideal, however, even if the gasket is entirely located outside the rim, some noise reduction will occur due to the damping effect of the gasket. Please use fitment chart below to determine size.

Rural Delivery
If your shipping address is classified as a "rural delivery" (RD) address you are required to select the rural delivery shipping option at checkout. Please note that if your address is rural delivery and the incorrect shipping option is selected, your order will not ship until the additional fee for rural delivery has been received. It is the responsibility of the buyer to ensure that the appropriate delivery option is selected to avoid any delays to an order. If you are unsure whether your address is classified as a rural delivery address, please check with your local postal service or contact us for assistance.
SHIPPING BIKES:
We do ship bikes! Every bike that is sold is first assembled, tuned, and tested to ensure it is at it's best operational order when it reaches you. If your bike needs to be freighted to you, it will then be boxed with factory-level care and precision to ensure minimal risk and assembly when it arrives.
All bikes that are shipped will be partially disassembled to fit within courier size constraints. We always endeavour to reduce the complexity and amount of re-assembly possible; however, we always recommend you have the bike reassembled or inspected by a qualified bicycle mechanic before riding.
DELIVERY FAQ'S
How long does delivery typically take?
Delivery times are generally 3-5 working days on average; however, please allow an extra 1-2 working days for Rural delivery. Note that this is not a guarantee, but an observational quote based on typical delivery times. We often see faster delivery, and rarely see longer wait times unless:
- You have ordered a bike. Every bike that we sell and ship in a box is first assembled, tuned, and tested to ensure it is it's best operational order when it reaches you. Please allow for an additional 2-3 working days while this takes place. In the case of an e-Bike, please allow for a further working day as we organise Dangerous Goods shippment.
- Your order is a custom order (not-in-stock or standard stocked items) that has to be specifically ordered from suppliers - we will do our best to communicate any potential delays.
- If your order requires customisation or additional labour (eg. customising handle bars, changing of parts on a bike, etc.)
- During peak seasons or public holidays, delivery times can be extended due to courier demand and delay.
- Please note that there may be delays in receiving your online order from 24th December until the 11th of January, due to limited courier runs.
What if there is a delay extending beyond the quoted time?
Please be aware that our control is limited once it has been handed to the courier. Once you get a tracking number, the job is booked with the courier and it is in their hands, not ours, so please be aware of the following:
- Couriers have their own specified policy regarding time frames, delays, damage and logging inquiries for lost goods.
- If goods are damaged in transit, the issue needs to be logged directly with the courier company.
Based on this, we always recommend calling the courier company first as sometimes it can be as simple as a lost courier card and the package being at your local depot. All these details will be in the tracking information emailed to you when your order was dispatched. By directly contacting the people handling your order, it reduces the chain of communication so all your questions can find answers in a faster and more accurate fashion.
If you are still having trouble or have any additional questions, feel free to contact us and we will do what we can to help.
