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.
Hassle free returns
Subject to the terms set out below we are happy to offer a refund or exchange on all goods except goods which are special orders or nutrition products, or where we have expressly advised you that there is no right to return the goods ordered (save in the event the goods are faulty) provided the goods are returned to us within 14 days of delivery to you.
If you return goods to us and request a different size or alternative product we will send it out free of charge (subject to stock availability). If you require a refund (or the replacement item is not in stock) we aim to process refunds within 2 working days of receipt of the goods. It is your responsibility to ensure that the item is returned to us safely and securely and in saleable condition.

For all goods returned please include a letter giving details along with a copy of the original receipt. Returned goods must be unused and with all appropriate packaging and labelling intact.

Season:2025
Brand:Silca
Code:SIAMAC059ASY0100
SILCA Ultimate Sealant is a one-step process lasting +6 months and still, above all else, sealing punctures on race day.
The original sealant formulation, released 2.5 years ago, was designed primarily for effective puncture sealing by maximizing the surface area of the liquid latex for enhanced performance. Pro racers valued its convenience, as they frequently changed tires based on race conditions and could easily pour in fresh sealant without needing to inject it through the valve. However, two main concerns from more casual cyclists were that it dried out quickly when not in use, and its composition of the longer strand carbon fiber made injection difficult and problematic, leading to a potentially messy installation if not handled carefully.
The old Natural Latex formula needed a two-step process to stay liquid longer. That has been eliminated with this new blend of natural and synthetic latex.
