EDELRID Spoc Roll Oasis tubular belay device, One Size — roller for smooth feeding & secure cam clamp

The EDELRID Spoc Roll Oasis is a compact tubular belay device with a ball-bearing aluminium roller and adjustable backstop that delivers high-efficiency rope handling for single and light double ropes from 7.0–11.0 mm.

Engineered for climbers who need a versatile, lightweight belay and lowering tool, the Spoc Roll Oasis combines a low-friction roller and secure camming clamping action to make feeding and braking smooth even on icy or dirty ropes. Its design also lets the backstop lock open, converting the device into a simple pulley for hauling or friction-reduction tasks, while the aluminium construction keeps weight down without sacrificing durability.

How does the roller improve rope handling?

The 20 mm ball-bearing aluminium roller reduces friction during belaying and lowers, so rope feeds more predictably and with less effort. That higher efficiency helps when belaying long leads or lowering a climber on thin or elongated ropes.

• 20 mm wheel diameter for consistent rope contact
• Ball-bearing construction increases efficiency to about 92%
• Smoother rope movement reduces jerks and hangs on long lowers

Can it handle icy or dirty ropes safely?

Yes — the Spoc Roll Oasis uses aggressive clamping cams that bite reliably into the rope sheath, giving positive control even when contaminants are present. The device balances low rolling friction with strong bite when braking or holding a load.

• Clamping cams designed for secure grip on soiled rope
• Works well across a broad rope range (7.0–11.0 mm)
• Suitable for EDELRID RAP LINE as well as standard ropes

When would I use the fixed backstop as a pulley?

Fixing the backstop open transforms the Spoc Roll Oasis into a simple single-sheave pulley for lowering, redirecting, or hauling systems. This dual use adds functionality on multi-pitch routes or base operations where a lightweight pulley is handy.

• Backstop can be secured open for pulley mode
• Useful for hauling gear or building hauling systems
• Compact, lighter alternative to separate dedicated pulleys

What ropes and tasks is this device best suited for?

The Spoc Roll Oasis is optimized for single ropes and light twin/two-rope use in the 7.0–11.0 mm range and is compatible with EDELRID RAP LINE. It excels in sport climbing, alpine approaches, and rescue or rigging scenarios where smooth feed and secure bite are both needed.

• Compatible with 7.0–11.0 mm ropes and EDELRID RAP LINE
• Good for belaying, lowering, and light hauling tasks
• Compact profile for sport, trad, and alpine climbing kits

Who is this for: Climbers and riggers who want a small, multi-functional device that combines near-pulley efficiency with secure camming bite will appreciate the EDELRID Spoc Roll Oasis. It suits technical sport and alpine climbers, guides, and rope teams who carry minimal gear but still need reliable control on thin or contaminated ropes. If you need a belay device that doubles as a lightweight pulley and works across a wide rope diameter range, this model is built for that purpose.
