Holeshot Fast Flow Tubeless valves: High flow, less faff.
$44.99
WHAT SIZE GRIP DO I NEED?

Your ideal grip size depends on your riding style, trail conditions, hand size, and whether you wear gloves or not. Selecting the right grip can be as much personal preference as it is a science.

As a general rule, most people normally opt for a thin grip, but generally people with bigger hands (XL glove size and upwards) should opt for a thicker grip.
However, some aggressive riders (even those with massive hands) may prefer a thin grip to achieve better bar feel and precise control. Conversely, people with smaller hands, who might otherwise be best suited to a thinner grip, may prefer the comfort and fatigue reduction of thick grips over ultimate control.

FAST FLOW VALVES

2X FASTER THAN PRESTA

It's about Fast-Flow 2x higher air flow* and higher pressure seats tyres to rims withease, reducing set up time and faff. No special tools, pumps or compressors required.

  • Increases the ability for sealant to FLOW directly into the tyre, removing the need to remove the Presta core or unseat the tyre.
  •  

*On a calibrated constant 45psi air flow test rig, Holeshot flows at 110 L/min vs standard Presta at 54 L/min

NO SEALANT CLOG

Larger sealing surfaces improve airflow and significantly reduce sealant clogging.

All internal and external surfaces are made from 7075 aluminium and fully anodised, which stops sealant from sticking.

No more blocked valves and fewer Presta valves ending up in the bin.

Plus, the Holeshot Fast Flow Tubeless Valve is fully serviceable, prolonging its lifespan.

Fail Safe Design

With the unique patent pending design, the “bell house” and
valve seal is moved inside the rim. It therefore remains
uncompromised if the shaft is struck by a rock or damaged.
Racers and riders can therefore finish their race run or ride.

VALVES FOR LIFE

If there is ever an issue or the valve becomes damaged, the Holeshot Fast Flow Tubeless Valves are backed by Peaty’s “Valves for Life” guarantee.

The Holeshot Fast Flow Tubeless Valve is designed to be fully serviceable at home with full service and accessory kits available.

E-Bike Lube Cap

The Holeshot valve packs more features than “just a tubeless
valve”, the caps also double up in function. Each pair of valves
come with:

  • 1x E-Bike Lube cap: Anti-spin on the crank spider
  • 1x Spoke key cap: For trail side emergencies

IT'S YOUR RIDE,
JUST BETTER

Product information

Fast Flow Valves, What's Fast Flow

Experience a massive 200% increase in airflow that makes seating tires to rims effortless.

This high air flow architecture provides the necessary pressure to snap beads into place instantly, significantly reducing setup time and workshop faff without the need for compressors.

By utilizing a large bore internal design, sealant flows directly into the tire, completely removing the requirement to remove the Presta core. It is a streamlined, high-volume tubeless solution built to get you out of the garage and onto the trails faster. High low, less faff.

Patent Pending "Bell House"

The Holeshot’s unique "bell house" relocates the primary seal from the top of the 7075 aluminium stem to the base, effectively moving the critical airtight components inside the rim.

By sheltering the seal internally, the system remains uncompromised even if the external valve shaft is struck by a rock or damaged on the trail.
This ensures that racers and weekend riders alike can finish their ride without a sudden loss of pressure, providing a level of reliability standard valves simply can't match.

Compatible with all rim inserts

The innovative internal "bell house" design ensures the Holeshot Fast Flow Tubeless Valve is a truly universal solution, offering full compatibility with all major tire inserts.

Unlike traditional valves that can be blocked or restricted by foam liners, the protective cage maintains a clear path for air and sealant to reach the tire. This allows for rapid inflation and easier maintenance. Less faff, more riding.

More than just a valve

The Holeshot valve packs more features than “just a tubeless valve”, the caps also double up in function. Each pair of valves
come with:

  • 1x E-Bike Lube cap: Anti-spin on the crank spider

  • 1x Spoke key cap: For trail side emergencies

Even with these functions, the valves weigh in as one on of the lightest High-Flow valves on the market - just 11g per pair for 42mm and 14g a pair for 60mm.

Valves for Life

Designed to stay on your bike and out of the landfill, the Holeshot Fast Flow Tubeless Valve is fully serviceable at home with a simple, removable circlip for easy cleaning and seal replacement.

Every set is backed by our "Valves for Life" guarantee, ensuring that if your valves ever become damaged or experience an issue, we have you covered. It is a long-term, sustainable solution built to endure the toughest trails, ride after ride.

MX Valves

We designed our MX valves to suit all Bosch eMTB bikes with a rear rim speed sensor - a world first!
The mix of a 60mm rear and 42mm front valve gives you the added length required for the perfect setup.

What size do I need?

Peaty's Holeshot Fast Flow Tubeless Valves come in 3 lengths. 42mm, 60mm and MX (42/60mm) for Bosch eBikes.

As a rough guide, we recommend:

  • MTB, Urban and XC rims: 42mm
  • Road and Gravel rims: 60mm
  • Bosch eBikes: MX 42/60mm - 60mm rear to allow for the motor sensor.

We recommend there to be around 15mm of valve stem sticking out from your rim - ultimately depending on the insertion depth required by your pump head.

The exact fitment would vary on how much of a dip there is in the rim bed. Some rims also have a recessed valve hole on the inside of the rim to reduce the length of the valve required.

You can check these lengths by:

  • Poking a long thin object (like a spare spoke) through your valve hole then measuring the distance from the lowest point where the valve will sit into the rim to where the valve exits the rim.
  • Measure the insertion depth your pump head by pushing your existing valve into the pump then marking where the valve stem exits the base of the pump head when pushed fully inside.
  • Add the first measurement to the second measurement and if this is less than 60mm then you should be fine.

    Always measure your rims before purchasing or contact your rim manufacturer for further recommendations.

 

How Much Do They Weigh?

  • Weight:
        • 42mm - 11g per pair
    • 60mm - 14g per pair

Set Up Instructions

Valve Installation Instructions:

1. Remove the valve cap, O-ring and lock nut.
2. Insert the valve through the valve hole in your rim.
3. Push the O-ring onto the valve stem.
4. Thread the lock nut onto the valve stem.
5. Hand tighten the lock nut until firm.
6. Screw on the valve cap.

Sealant Injection Instructions:

1. Mount the tyre onto the rim and inflate first with no sealant ensuring both beads are fully seated (locked into position on the rim).
2. Deflate fully. Take care not to dislodge the tyre bead from the rim..
3. Shake bottle / trail pouch thoroughly to evenly distribute platelets and fibres.
4. Start with the valve in the 10 o’clock position.
5. Attach the pipe or trail pouch nozzle firmly onto the valve.
6. Rotate valve to 8 o’clock and keep bottle / trail pouch elevated.
7. Squeeze sealant into valve at a steady rate.
8. If pressure builds up or flow stops, ease your grip to allow air back into the bottle or pouch. This clears any platelet build-up from the valve. Then resume squeezing..
9. Repeat until required amount is injected into tyre.
10. Rotate back to 10 o’clock to reduce any leakage when removed.
11. Remove pouch or pipe.
12. Inflate & Ride!
