I'm really interested in this rope but am a little worried that it is too thin for sport climbing. I think the gri-gri takes 8.9-11mm ropes so it wouldnt be safe but are there plenty of other belay devices that is is compatible with?

Hi Callum, You're absolutely right, the opera is too thin for use with the Grigri 2; In fact, we are not sure there are any auto-locking belay devices on the market right now that are rated for 8.5mm ropes. If you are climbing sport routes where every gram counts then the Opera could be the rope for you but please make sure your belayer knows what they are doing; the breaking power of belay devices will be significantly less with the opera compared to your avg. sport climbing rope. If you are unsure then we might recommend a slightly thicker rope. The Mammut serenity has many similar specs to the Opera but at 8.9mm can technically be used with the Grigri 2, even though it is right on the limit. Hope that helps, Dave

Correction: the new Serenity rope is now 8.7mm diameter and so is not suitable for use with the Grigri.
