Very easy to use even for me with only one functioning hand add a 10" piece of redi rod and some oversize fender washers and you got capabilities for pull/install wheel bearings also

I think a spanner wrench is always a better option, yet in tight spaces this is the only option. Brass tip does wear quickly, yet it does keep you from damaging your spanner rings.

Thought this was going to be something that makes setting sag a one man job , its just a ruler with a peg to stick in the axle , so you still need someone to read the measurements when you sit on the bike.
