Runwell - Pins7710

The Faster, Smarter Way to Remove Crank Caps

PINS7710 is a precision-machined stainless steel tool designed specifically for installing and removing crank caps. Inspired by the crank caps used on DURA-ACE FC-7710, it combines secure engagement with exceptional ease of use.

Unlike stamped tools that can slip under load and scratch the crank cap, PINS7710 features two precision-machined pins that fit securely into the cap's holes for a confident, damage-free grip. The threaded pin design ensures a solid connection to the handle, providing reliable performance every time.

What truly sets PINS7710 apart is the single pin located on the opposite side of the tool. Anyone who has installed or removed crank caps knows how tedious it can be to spin them on and off with your fingertips. The single-pin design allows you to quickly rotate the cap, dramatically speeding up the process and making routine maintenance surprisingly satisfying.

Crafted entirely from stainless steel, PINS7710 offers exceptional durability and corrosion resistance. The handle is laser-cut for a clean, refined appearance, while all three pins are precision-machined from stainless steel for long-lasting performance. Rounded pin tips help prevent accidental scratches, and an integrated stopper ensures the dual pins remain perfectly aligned and protrude to the same length for consistent engagement.

Notes
*The center-to-center spacing of the dual pins is 16.7 mm. Please verify compatibility before use with crank caps from other manufacturers.
* If a pin becomes loose, remove it, apply a small amount of threadlocker (such as LOCTITE®) to the threads, and reinstall it. Ensure the pin is fully seated against the stopper.
