Sprint ST Modifications Spanner Wrench Mod   Spanner Wrench Mod Submitted By: Michael Emery Above is the modification I had made to the spanner wrench. I had a local welder add a few inches to the handles length - which allowed me to toss the piece of junk pipe handle extension. The wrench still easily fits under the seat, but is much much easier to use when adjusting chain tension. The arrow shows where the factory handle stopped. It cost me $20 to have done and you CANNOT tell the modified wrench didn't come that way from the factory.
