Recommended by Tubolight for CX and/or road tyre use

When fitted, these narrow tubeless liners sit tightly in between the tyre beads, the the lower profile is designed to hold the bead in place from the inside, significantly reducing the chances of burping or rolling off the rim when punctured

Some liners can leave lower volume tyres feeling dead/full of liner. The upper profile of these liners is shaped leave more of the CX tyre's air volume available inside the tyre, so do not change the tyre's feel/performance

Weighing just 35g for a pair, they are far lighter than other liners

You can run much lower tyre pressures than you otherwise could, increasing the available grip from tubeless tyre systems

These are not designed as a full run flat solution, with punctured CX size tyres you can feel the liner but have to ride very carefully, you're likely to damage the tyre, rim and liner if you ride too hard - so is not recommended

Highly recommended to be used to get the best from Challenge's HTLR tyres

They come as a pair with 50mm liner specific tubeless valves. Let us know if you need a different length (40 or 70mm) in the notes section in checkout 

Recommended internal rim widths from 17mm up to 22mm

Can also be used with 28-30mm road tyres

With road tyres, they are a run flat solution
