These are the real thing when it comes to Heavy duty tubes. Super heavy-duty wall thickness to help prevent snake bites when you are admiring the scenery and don't see that pesky rock in the middle on the track.
Place these heavy-duty tubes in and minimise the risk of that unwanted flatty.
17", 18" and 21" - to cover all your adventure riding.
