Park Tool’s p-handled wrench set is the de-facto starter set for bicycle maintenance. Featuring a convenient Bondhus balldriver and a high-torque straight hex tip, these drivers are highly versatile, and can be used on bikes or around the home and shop.
The offset P-handles of these drivers make them quite comfortable to use, even in high torque applications. It is because they have two hex tip options (ball and straight) that make them a better choice for working on bikes than standard T-handled or L-shaped wrenches.
If you already have a complete metric ball-tipped hex wrench set, you may want to consider purchasing separate P-handled drivers in the most commonly used sizes (4mm, 5mm, 6mm) instead of a complete set to save some cash.
