How to fix BARTubeless


Thanks to our original repair kit, BARTubeless® can be easily repaired even at home. For example, you can easily replace one or more spokes without compromising the seal. If properly repaired, BARTubeless® retains all sealing performance and durability of the brand new product.

Replacing a spoke

remove the tire

in order to access the rim channel and the BARTubeless®

cut the polymer strip

with a cutter, until a wedge is obtained around the nipple

liberare il nipplo

remove the wedge

thus exposing the nipple: it is now possible to replace the spoke normally

After replacing the spoke, to restore the seal of BARTubeless® proceed with the repair using the kit as shown below:
