Overview
What Does the Muc-Off Tubeless Kit Include for Road?
The Muc-Off Ultimate Tubeless Kit for Road, Gravel, and CX contains everything needed to set up a tubeless-ready wheelset. Included are a 10m roll of 21mm rim tape (enough for two rims), seal patches, two 44mm CNC-machined tubeless valves, and two pouches of No Puncture Hassle Sealant, which seals tears and holes up to 7mm and also seals porous tires and bead and rim gaps.
To fit the tape, keep pressing it down as you pull it taut around the rim, and after a few centimeters it holds itself in place. The valves have a removable core, and the kit includes a valve core removal tool that doubles as a spare valve cap. Each sealant pouch attaches straight to the valve. Just make sure your wheels and tires are tubeless ready before you start.

FAQ
Good questions
Get to know Muc-Off

There's more to Muc-Off than this one product. Our Muc-Off page has the full Muc-Off lineup we carry and more about the brand.
Visit the Muc-Off page →Is 44mm long enough for deep-section road wheels?
Muc-Off pairs 44mm valves with road, gravel, and CX wheels with shallow rims. For deep rims, this same kit comes with 60mm valves. If you are unsure which length your rims need, check your rim maker's instructions.
How much sealant is included?
Each kit includes two pouches of No Puncture Hassle Sealant. Muc-Off's directions have you remove the valve core with the spare valve cap, attach the pouch to the valve, and squeeze the sealant into the tire.
Do I need tubeless-ready wheels and tires?
Yes. Muc-Off says to make sure you have tubeless-ready wheels and tires before you convert. The 10m roll of rim tape is enough for two rims.
