Vittoria Universal Tire Sealant x 4 Litres
- Price: ยฃ35.96 (ยฃ8.99 per litre)
- From: Freewheel

This is a universal sealant for all types of bike tyres, and thereโs enough here to keep your entire mountain bike fleet rolling for months to come. The liquid consistency of this ammonia-free sealant means itโll fill even tiny holes, and itโs designed not to turn into big lumpy monsters inside your tyre as it ages. Itโll seal larger holes up to 7mm thanks to the โplateletsโ in the mixture, and promises to stay fresh and functional for up to 1,200 km or 3-5 months. To make sure you keep track of when you last topped up your tyres, thereโs handy label on the side of the bottle that you can fill in.
How Do I Enter
Log in to reveal the entry form in this story and answer the question youโll find there. The answer you seek will be in the video above.
Answering the daily question gives you two chances to win: youโll be entered into the daily draw for that dayโs prize; and youโll also get one entry into the Megasack draw.
Every time you correctly answer a daily question and enter a daily draw, you get another entry into the Megasack. You can go back and enter the daily answers after that daily prize has been drawn, and it will still give you an extra entry into the Megasack draw.
The rules are strictly one member one entry/day. If we detect any attempt at multiple daily entries we will remove all those users entries from the draw.
And another thingโฆ Really sorry to our overseas readers but we can only send prizes to a UK address. If you have a friend or an address you can use in the UK for a prize then by all means enter.
