How to Fit (and Remove) Stubborn Tubeless Tyres

The Struggle is Real: We have all been there—wrestling with a stiff tubeless tyre that simply refuses to budge. Whether you are trying to pop an old bead off or wrestle a fresh tyre on, here is the professional guide to saving your thumbs and your rims.

Part 1: Removing a Stuck Tyre

If you are struggling to break the bead seal, you might need to get a bit “agricultural” with your technique.

• The Foot Method: Place the wheel flat on the floor (protect the rotor/cassette). Place one foot on the “high” side of the wheel to hold it down. Place your other foot on the tire bead and sidewall, then push down firmly to pop it off the rim.
• The Vice Method: Alternatively, you can use a workshop vice with a similar squeezing action to compress the tyre and break the bead seal—just be gentle with your rim!

Part 2: Pre-Installation Prep

Before you even touch the tyre levers, there is one secret trick that changes everything: Heat.

Pro Tip: Get the tyre warm before fitting. Leave it in the sun for 30 minutes or carefully place it near a heat source. A warm tyre is significantly more pliable and stretchy, which will save your thumbs a lot of pain.

Check Your Tape: Ensure your tubeless rim tape is properly applied and not too thick. Overly thick tape reduces the diameter of the rim bed, making tight tyres even harder to mount.

Part 3: The Installation Technique

The Golden Rule: The Central Well
When fitting the bead, you must push the installed part of the bead down into the deepest part of the rim (the central well). This creates slack, allowing you to inch that final, tight section over the rim lip.

Lever Technique:
Start at the valve and work the tyre on. When using levers for the final tight spot, ensure you use long, plastic-coated levers (like the Lezyne Power Lever XL). The plastic coating is essential to prevent scratching or damaging your expensive rims.

If the tyre keeps slipping off, tools like the Crankbrothers Slider are invaluable. They have clips that hook onto the rim wall, preventing the bead from migrating back off while you work on the other side.

Part 4: Seating the Bead

Once mounted, you will usually need a sudden blast of air to seat the bead—use a pressure canister, a tubeless-specific pump, or a compressor.

Still won’t pop?
If the bead refuses to seat, lubrication is your friend. Apply a little washing-up liquid, silicone spray, or even WD40 around the bead to help it slip into place.

Tubeless vs. Clincher: Are You at Risk of a Blow-off?

The Big Question: In our latest Tech Q&A, we tackle a common fear among cyclists considering the switch: Is a tubeless tyre more likely to suffer a catastrophic blow-off than a traditional clincher tyre with a tube?

The Expert Verdict: The Opposite is True

According to Simon von Bromley, Senior Technical Writer at BikeRadar, the fear is largely misplaced. In fact, tubeless systems are generally safer and more secure than their tubed counterparts.

The secret weapon is the sealant. While its primary job is to plug punctures, it also acts as an adhesive. As the sealant dries, it effectively glues the tyre bead to the rim hook.

Why it matters: Anyone who has ever tried to remove a well-seated tubeless tyre knows how strong this bond can be. Because of this “glued” effect, even if you suffer a sudden deflation, a tubeless tyre is far more likely to stay seated on the rim compared to a standard clincher.

What Actually Causes Blow-offs?

While modern engineering has made spontaneous blow-offs extremely rare for both system types, failures can still happen. However, the technology isn’t usually to blame. Most incidents are caused by:

• Incorrect Installation: The bead not being properly seated during setup.
• Incompatibility: Running a tyre and rim combination that isn’t designed to work together (e.g., hookless rims with incompatible tyres).
• User Error: Severe under-inflation or over-inflation beyond the manufacturer’s limit.

The Bottom Line: Don’t let the fear of blow-offs stop you. With a correct setup, tubeless is not only a performance upgrade but arguably a safety upgrade too.

Road Bike Disc Brakes 101: How They Work and Why They Differ From Rim Brakes

The Fundamental Difference: Braking Location
The most critical distinction between traditional rim brakes and modern disc brakes lies in where the braking forces are applied.

• Rim Brakes: As the name suggests, these clamp directly onto the sidewalls of the wheel rim. In this design, the rim acts as a structural component, a mounting base for the tire, and a braking surface—all in one.
• Disc Brakes: Disc systems shift all braking duties to a separate rotor. This rotor is smaller in diameter and mounted directly to the hub, similar to the braking systems found on cars and motorcycles. The brake caliper is mounted to the frame and fork but sits much closer to the wheel axle.

How They Operate: Cable vs. Hydraulic

Another key difference is the actuation mechanism—how your hand movement translates to stopping power.

1. Cable-Actuated Systems
Rim brakes (and some entry-level disc brakes) typically use braided steel cables housed in casing. When you pull the lever, it physically pulls the cable, forcing the caliper to clamp down.

2. Hydraulic Systems
Disc brakes are most commonly hydraulic. In this fully sealed system, cables are replaced by non-compressible fluid.

The Mechanism: Pulling the lever pushes a plunger inside a master cylinder. This forces fluid through a hose to the caliper, creating hydraulic pressure that extends the pistons and clamps the brake pads onto the rotor.

A Note on Mechanical (Cable) Disc Brakes

You will also find cable-operated disc brakes, typically on budget-friendly bikes. Like rim brakes, these rely on a wire to actuate the caliper. While more affordable, they are generally less efficient than hydraulic systems due to friction and cable stretch.

The Essential Guide to Bicycle Brake Cables

Brake cables are the lifeline of mechanical braking systems found on road bikes, mountain bikes (MTB), and BMX bikes. A standard cable system consists of two critical components: the inner wire (typically made from stainless or galvanized steel) and the protective outer housing. Over time, friction and tension cause these cables to stretch, fray, or corrode, making regular replacement essential for rider safety.

Universal Compatibility

One of the advantages of mechanical brake cables is their versatility. The same cable technology is interchangeable between different bike types, whether you are running:

• Rim Brakes: Including Caliper, Cantilever, and V-Brakes.
• Disc Brakes: specifically mechanical (non-hydraulic) disc systems.

⚠️ Critical Safety Note: Brake vs. Gear Housing

Although they look similar, brake housing and gear (shifter) housing are NOT interchangeable.

Gear housing is designed for compression resistance to maintain shifting index accuracy, while brake housing is built to withstand the high bursting force of braking. Never use gear housing for brakes, as the high tension can cause the housing to rupture, leading to sudden brake failure.

Buying & Installation Tips

When purchasing, you typically have two options:

• Inner Wire Only: Ideal for quick repairs if your housing is still in good condition.
• Complete Cable Kits: Includes two inner wires (approx. 1.5mm – 1.6mm thick) and a length of outer housing. This is recommended for full maintenance.

Pro Tip for Cutting: When installing, use your old cable housing as a template to cut the new housing to the exact length required for your frame’s cable stops. Always ensure a clean, square cut to prevent friction and ensure smooth lever action.

Why Upgrade?

While basic cables perform the essential function, investing in higher-end cables (such as Stainless Steel or Teflon-coated) is a cost-effective way to improve performance. Premium cables offer superior corrosion resistance and lower friction, resulting in lighter lever action and more responsive braking power.

Studded Bike Tyres: Essential Winter Gear or Overkill?

Riding on snow and ice can be treacherous. Studded tyres offer the ultimate solution for winter control by embedding metal spikes—often tipped with durable tungsten carbide—directly into the tread. These studs act like claws, penetrating the ice to provide traction that standard rubber simply cannot match.

The Pros and Cons

The Advantages: The primary benefit is safety. For daily commuters and winter adventurers, studded tyres provide unmatched grip on icy surfaces, significantly reducing the risk of dangerous slips.

The Trade-offs: Performance comes at a price. The added metal increases weight, making acceleration feel slightly sluggish. They are also noisier on asphalt (often described as sounding like a “tank”), are more expensive than standard tyres, and typically require a 40km “break-in” period on asphalt to seat the studs properly.

Usage Tips for Maximum Grip

• Can I ride on asphalt? Yes. While noisy, they handle mixed terrain well. However, check local regulations, as some regions restrict them on high-speed e-bikes to prevent road damage.
• What tire pressure is best? Lower is better. A lower pressure increases the contact patch, allowing more studs to bite into the ice simultaneously for maximum stability.

The Verdict: Do You Need Them?

If you live in a region where ice and hard-packed snow persist for weeks or months, studded tyres are a non-negotiable safety investment. However, for temperate climates with only occasional frosty mornings, standard winter tyres may be a more efficient, lightweight, and cost-effective choice.
