Holdfast Skewer Adaptor for 15mm Thru-Axle Carriers
The Holdfast Skewer Adaptor solves a common problem for riders with mixed bike fleets: mounting a quick-release skewer bike onto a carrier built for 15mm thru-axles. Drop the adaptor into the thru-axle clamp, secure your bike’s QR skewer, and you’re loaded – no other parts required.
Specifications
- Compatibility: All Holdfast 15mm thru-axle carriers and most aftermarket equivalents
- Bike type: Quick-release skewer fork ends
- Construction: Durable steel adaptor body
- Use: Drop-in, no tools required
Why You Want One
- Use one carrier for the whole fleet: Skewer hybrids, kids’ bikes and older road bikes all fit a thru-axle carrier with the adaptor in place.
- Quick swap: Slot in, secure the skewer, ride out. No clamp adjustment, no spacers, no tools.
- Travel-ready spare: A small, light part that lives in the boot for guest bikes and trip surprises.
Pair With a Carrier
Use the Skewer Adaptor with any Holdfast bike carrier built for 15mm thru-axles, including roof-mounted platforms. Browse bike carrier accessories for axle adaptors, replacement straps and locking parts.
Tip: Keep one adaptor permanently in the boot – it eliminates the awkward “your bike won’t fit my carrier” moment at the trailhead.
