What You'll Need

Essential Components

• Tubeless rim tape (match your rim width)
• Tubeless valves (44mm or 60mm depending on rim depth)
• Tubeless sealant (Magic Milk Biobike, Original Formula, or Hi-Fibre Race)
• Tubeless-ready or tubeless-compatible tires
• Tubeless-ready or tubeless-compatible rims

Tools Required

• Tire levers (plastic, not metal)
• Floor pump or compressor (for bead seating)
• Scissors or sharp knife
• Isopropyl alcohol and cloth
• Valve core remover tool
• Sealant injector or bottle

Step-by-Step Tubeless Conversion

Step 1: Prepare the Rim

1. Remove existing tire and tube completely
2. Clean rim bed thoroughly with isopropyl alcohol
3. Remove any old rim tape or adhesive residue
4. Inspect rim for damage, burrs, or sharp edges
5. Ensure spoke holes are clean and dry
6. Let rim dry completely (5-10 minutes)

Step 2: Apply Tubeless Rim Tape

1. Choose Correct Width: Tape should be 2-4mm wider than internal rim width
2. Start at Valve Hole: Begin taping 15cm before valve hole
3. Apply Tension: Pull tape tight and smooth as you wrap
4. Center the Tape: Keep tape centered in rim channel
5. Overlap Layers: Wrap 2-3 complete layers for best seal
6. Finish Past Valve: End 15cm past valve hole, overlapping start
7. Press Firmly: Use thumb or plastic tool to press tape into rim bed
8. Trim Excess: Cut tape cleanly at end point

Step 3: Install Tubeless Valve

1. Locate valve hole through tape
2. Pierce tape at valve hole with sharp tool (awl or valve itself)
3. Make hole just large enough for valve stem
4. Insert valve stem through hole from inside rim
5. Thread valve nut onto stem from outside
6. Tighten valve nut firmly (hand-tight plus quarter turn)
7. Ensure valve is perpendicular to rim
8. Check valve base seals completely against tape

Step 4: Mount the Tire (First Bead)

1. Check tire rotation direction marking
2. Start tire installation opposite valve
3. Work first bead onto rim by hand
4. Use tire levers only if absolutely necessary
5. Ensure bead sits in rim center channel
6. Work around rim until first bead is fully seated

Step 5: Add Sealant

Method 1: Through Valve (Recommended)

1. Remove valve core with valve core tool
2. Attach sealant injector to valve stem
3. Inject recommended amount of sealant (see chart below)
4. Reinstall valve core and tighten
5. Proceed to mount second bead

Method 2: Before Second Bead

1. Leave second bead unmounted
2. Pour sealant directly into tire cavity
3. Distribute sealant around tire
4. Quickly mount second bead

Sealant Amount Guide

Tire Size	Sealant Amount
Road (700x23-28c)	30-60ml
Road (700x30-35c)	60-75ml
Gravel (700x35-45c)	75-90ml
MTB (29x2.0-2.4)	90-120ml
MTB Plus (27.5x2.8-3.0)	120-150ml

Step 6: Mount Second Bead

1. Start opposite valve, work second bead onto rim
2. Push tire beads into center channel as you work
3. Final section near valve will be tightest
4. Use tire levers carefully if needed (avoid pinching tape)
5. Ensure both beads are in center channel before inflation

Step 7: Seat the Beads

1. Initial Inflation: Use floor pump or compressor
2. High Volume Air: May need to remove valve core for faster airflow
3. Listen for Pops: Beads seating make distinctive popping sounds
4. Inflate to 40 PSI: Higher pressure helps bead seating
5. Check Both Sides: Ensure beads are evenly seated all around
6. Bounce and Shake: Help distribute sealant

Step 8: Distribute Sealant

1. Lay wheel flat and rotate to coat entire inner surface
2. Stand wheel upright and rotate slowly
3. Shake wheel side to side
4. Repeat for 2-3 minutes to ensure full coverage
5. Check for air leaks (listen for hissing)
6. Sealant will seal small leaks within minutes

Step 9: Set Final Pressure and Test

1. Adjust to your desired riding pressure
2. Let sit for 15-30 minutes, check pressure again
3. Top up if needed (some air loss is normal initially)
4. Spin wheel to check for wobbles or uneven seating
5. Wipe excess sealant from tire and rim
6. Repeat process for second wheel

Troubleshooting Common Issues

Beads Won't Seat

• Remove valve core for maximum airflow
• Use compressor or tubeless inflator for burst of air
• Add soapy water to bead/rim interface
• Ensure tire is tubeless-ready (some tires won't seal)
• Check rim tape is smooth without wrinkles

Air Leaking from Valve

• Tighten valve nut (not too tight)
• Check valve base seal against tape
• Add small amount of sealant around valve base
• Replace valve if damaged or worn

Air Leaking from Rim Tape

• Check tape coverage is complete
• Look for wrinkles, bubbles, or gaps
• May need to re-tape with fresh tape
• Ensure tape width is correct for rim

Sealant Spraying Out

• Large puncture - may need plug repair
• Bead not fully seated - deflate and reseat
• Damaged tire sidewall - may not seal
• Add more sealant if needed

Maintenance Schedule

Every Ride

• Check tire pressure (tubeless loses air faster than tubes)
• Inspect for cuts or damage
• Top up pressure as needed

Monthly

• Check sealant level (shake wheel, listen for liquid)
• Top up sealant if needed (30-60ml)
• Inspect valve for clogs or damage

Every 3-6 Months

• Replace sealant completely
• Clean out dried sealant from tire
• Inspect rim tape condition
• Check valve seals and replace if worn

Pro Tips for Tubeless Success

• Temperature Matters: Warm tires seat easier - work in warm environment if possible
• Soapy Water: Light spray on bead helps seating and shows leaks
• Patience Pays: Some setups take time - let sealant work
• Quality Components: Use proper tubeless tape and valves for best results
• Fresh Sealant: Old sealant won't seal - replace regularly
• Practice First: Try conversion at home before trip or race
