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.

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

Silca Ultimate Tubeless Sealant V2 - 1-litre

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.

Features:

  • Seals 6mm+ punctures
  • Injectable through the valve (Injector sold separately)
  • Lasts 6+ months
  • Proprietary Natural and Synthetic Latex blend
  • Optimized carbon fiber strands
  • Advanced Foaming agents to carry carbon strands to a puncture
