If you split your saddle time between weekday commutes, weekend tours, and the occasional trail loop, swapping pedals gets old fast — and it usually means sacrificing either efficiency or confidence somewhere along the ride. The Funn Clast Clip-In Pedals eliminate that trade-off with a truly hybrid design.
What Makes Clast Different
- Dual-purpose performance : SPD clip-in on one side for efficient, repeatable power transfer; a pinned flat on the other for control in casual shoes or technical moments.
- Confidence on demand : 8 replaceable pins and a supportive platform ( W73 × L92 × H21 mm ) give stable footing when you unclip.
- Built to be ridden daily : A robust ADC10 die-cast aluminum body shrugs off strikes and weather without weighing you down.
- Serviceable longevity : CrMo axle with full-length bushing + cartridge bearing runs smooth and is easy to maintain or refresh.
- Balanced weight : At 385g per pair, Clast hits a sweet spot of light feel with real-world durability.
- Friendly clip-in feel : 5° of float helps your knees track naturally; an 18° release angle keeps you secure through chatter yet exits cleanly when you twist out.
Clip or Flat? How to Choose on the Fly
-
Clip-in (SPD side)
Reach for the clip-in when you want efficient cadence, steady torque, and confident climbing. It’s your go-to for long connectors, headwinds, and any ride where you want consistent power and less fatigue. -
Flat (8-pin side)
Flip to the flat when traffic gets dense, when you’re cruising neighborhood streets in everyday shoes, or when a trail feature asks for quick dabs and foot repositioning. The platform’s footprint and pins deliver bite and control, so you can move freely without feeling sketchy.
Quick tip: Anticipate. Clip for the long stretch; unclip and rotate before you hit the light, the curb, or the rocky chute. Clast’s balanced body makes the flip intuitiv.
Materials & Engineering: Why ADC10 Die-Cast Matters
At the heart of Clast is an ADC10 die-cast aluminum body. This material choice isn’t just a spec-sheet flourish — it shapes how the pedal behaves for years:
- Dimensional precision : Die-casting yields crisp geometry around the clip-in mechanism, pin seats, and body edges, so tolerances stay tight and engagement feels consistent.
- Strength-to-weight balance : ADC10 delivers dependable impact resistance and fatigue strength without excessive mass — ideal for a pedal that lives in city grime one day and takes rock kisses the next.
- Corrosion resistance : Day-in, day-out exposure to rain, road spray, and trail grit demands a body alloy that holds up cosmetically and structurally.
In practice, the ADC10 body helps the Clast keep its secure feel and snug hardware fit after countless flips, strikes, and seasonal maintenance cycles. It’s a pragmatic material for riders who actually ride — often.
Serviceability & Longevity: The Axle That Saves You Money
Pedals see brutal loads, contamination, and neglect. Clast’s axle system is designed for that reality:
- CrMo axle for high torsional strength and long-term durability.
- Full-length bushing + cartridge bearing pairing manages both radial and axial loads to keep rotation smooth.
- Cartridge axle design makes replacements straightforward when you finally wear things out.
Fit & Feel: Dial It to Your Style
- Spring tension : New to clip-ins? Start light and add a quarter-turn at a time until engagement is secure but exits don’t feel stubborn.
- Float & knees : The built-in 5° float lets your joints self-align at cadence, easing stress during long efforts.
- Release angle : 18° is a confidence-forward spec for rough ground. If you want quicker exits, use a lighter tension setting.
- Q-factor : At 54mm, Clast sits in a neutral zone that suits most riders. You can micro-tune stance via cleat position, shoe shims, or crank spacers.
Use Cases: Where Clast Shines
- Daily commute : Clip in for steady pace; flip to flats before intersections or tight maneuvers. Ride in cycling shoes or office shoes without swapping pedals.
- Weekend touring : Efficient miles when you’re ticking off climbs and valley floors; flats for café stops, town detours, and scenic photo breaks.
- Trail & all-mountain : Clip for the long approach and technical climbs; flip for playful sections, sessioning features, or when you’re building confidence.
- Learning clip-ins : Practice on calm roads or mellow trails with the safety of a flat platform always available. Confidence builds fast when the “bail-out” option is right there.
The Bottom Line
The Funn Clast Clip-In Pedals aren’t a compromise; they’re freedom. Clip-in efficiency when you want to fly, flat-pedal control when the moment calls for feel and flexibility. Anchored by an ADC10 die-cast body and a serviceable CrMo axle with bushing and cartridge bearing, they’re built for the messy, mixed realities of real riding. If you refuse to pick one style for every mile, Clast is the smarter, longer-lasting way to ride exactly how you want.
