Its safety wire. Solid overall, nothing special in terms of doing anything outside of its job. Be cool if it added a few HP and came with a slice of red velvet cake. Used it on three sets of grips, 2 x protaper and one set of mountain bike grips for a friend. No issues, just use common sense and don't twist it too tight.
Got this as part of the safety wire kit from Tusk and have no complaints. Used it to quickly secure my fuel line and grips. As long as it's not over-tightened this wire is just fine- but that goes for any safety wire, I imagine.
Perfect for wiring on your grips after gluing. Holds the grips tight. I use a standard double-wrap and wrap the grips at both ends and the middle. Never had a grip slip ever. Perfect for keeping around in the shop and cheap enough to buy. Major value !
