Part# 16239

We have two in stock.
Holds socket tool to BB axle to eliminate slippage during removal and installation. New spring preload allows increased flexibility and rotation during use.
New design works with square taper and splined axles with M8, M12, or M15 internal spindle thread.

Use with Pedro's Splined Bottom Bracket Socket. Compatible with Pedro's Pro Socket Handle.

If you have even battled with an over-tightened Shimano® and ISIS Drive® splined bottom bracket cup, you know why Pedro's created the BB Socket Holder. Though these types of bottom brackets proved themselves as the standard for many years and continue to be found on many bikes, the tendency for these shallow splines to slip during removal or installation has resulted in more than a few expletives, high frustration levels, and worst of all, injuries. The Pedro's BB Socket Holder II provides a simple, shop quality tool that solves this problem. The new design works on bottom brackets spindles with M8, M12, or M15 threads and adds spring preload for increased flexibility and rotation during use. Backed by Pedro's lifetime warranty.

New, and ready to go to work.

Mavic 631 Bottom Bracket Tool, Ref 670. New, $120.00/each

This is a very specific tool for the 631 crankset and BB. The model years of which were circa 1989/ 90 /91.

670 was a product code for the bottom bracket of the Mavic group set. If I remember, I think this tool was used to disassemble the bottom bracket, it served to unscrew the nut at the end to change the bearings.

Still shrink-wrapped onto its header card.
