Product Image BORG tubeless brass 40mm valves

BORG tubeless valves x2 40mm silver brass.


A pair of BORG tubeless valves for road, CX/gravel or MTB. The base is rectangular and fits all BORG rims well. They do work work with other rims. In the shop I fit them to BORG, Pacenti, Kinlin, DT Swiss, Shimano and other rims. These come form the same factory as some other more expensive well known branded valves. The eagle eyed may spot which brands I mean as this is the same valve. 

The collar is colour matched and there is an rubber ring to stop the collar scratching your rim. With some asymmetric rims leave out the rubber grommit and use the collar upside down. That works a treat. 

The valves all have removable presta cores.

Do them up tight and you will get a good seal. Install the tyre with soapy water and inflate. There should be no leak at the valve. If there is you have a tear in the rim tape or you have not fitted the valve correctly.

This is how you avoid installation woes.

Theses lovely valves are not carded to reduce waste.

These valves fit rims driiled for 6.5mm to 7.8mm holes. Rims without spoke hole/no tape may require manufacturer specific valves.


40mm long material brass.
