ClimbingMaintenance

Weaver synthetic upper climber straps replace the calf straps on your climbing spurs with a synthetic material that does not soak up water or stretch like old leather. Fresh uppers keep the shank tight to your leg so the gaff goes in at a consistent angle.

Why change the uppers

The upper strap holds the top of the spur shank against your calf. When it stretches or loosens, the spur rocks on your leg, the gaff angle changes with every step, and your ankles do more work than they should. On a long removal that is tiring and makes cutting out more likely.

Synthetic straps shrug off rain and sweat and do not need the oiling leather does. Combine them with new lower straps to make an older set of spurs feel solid again. Browse spurs and parts in climbing spurs.

Leather straps also crack and harden as they age, especially if they are stored wet or in a hot truck. Synthetic uppers avoid most of that, so a set of spurs that only comes out a few times a month stays ready to use. If your pads are flattened too, replace them at the same time so the new straps have something firm to hold against.

Fit and inspection

Check that the straps suit your spur model and your pads, then fit them so the shank sits snug without cutting off circulation. Buckles should close fully and the free ends should be secured so they do not catch on brush.

Inspect straps, buckles, pads, shanks and gaffs before every climb. Spurs are life-support gear on a removal: follow the manufacturer's instructions and ANSI Z133, use them only on removals or where rescue requires, and be trained before you climb on spurs.
