Category: Climbing Accessories

A very unique assisted-braking resistor device from Edelrid.  Designed to assist a belayer that is significantly lighter in weight than the leader.  The Ohm works by increasing the rope friction in the system, reducing the force being transmitted to the belayer, and allowing a lighter belayer to more easily hold a heavier climber. The Ohm can be carried just like the first quickdraw on your harness, pre-rigged with the lead rope already installed, and be ready to just clip the entire set-up to the first bolt off of the belay. This is not a belay device.  The belayer still uses their own regular belay device to belay the lead climber as they would normally.

Details

  • Assisted breaking resistor
  • Designed for single ropes from 8.9mm to 11mm in diameter
  • Minimum belayer weight is 40 kg (88 lbs)
  • Recommended weight difference between climbing partners (lead climber > belayer): 10kg- 40kg (22 lbs - 80 lbs)
  • Set-up is attached to the first bolt off of the belay
  • The belayer needs less braking force to arrest a fall
  • Easier for the belayer to lower a heavy climber
  • Reduces the risk of a possible ground fall
  • No increased resistance with paying out rope for a lead climber
  • Made in Germany
  • 470g

Carter H. ★★★★★

My belayer is about 40 pounds lighter than me, and the extra friction from the resistor device makes every catch feel smooth and controlled. I've noticed it activates reliably even on the first bolt.

Charlotte ★★★★★

I was nervous about the weight difference with my climbing partner, but the second a leader falls above me this thing catches smooth and solid. The way it increases rope friction automatically is a huge confidence boost for lighter belayers.

Thomas ★★★★★

My partner outweighs me by about 40 pounds and catching his falls used to yank me off my feet. This little gadget adds just enough friction to keep me planted, and honestly I barely notice it's on the rope until it matters. Worth every penny for mismatched climbing pairs.
