From the Dungeon With Profile Racing: Ep 3 The FIRST 19mm, 48 splined Crank Spindle.

Here’s another must see video from Profile Racing, who are celebrating their 50th anniversary this year. This video highlights the 19mm 48 splined spindles, their origins and how they were made. Check it out.

In celebration of Profile Racing’s 50th anniversary, owner and founder, Jim Alley, invites us into the company’s original Florida location where some sections of this dark and dusty industrial cave have been sealed off since 2004.
Over time, this building (appropriately named “The Dungeon” by employees) has become a time capsule; a host to historical artifacts capturing Profile’s legacy in both the automotive and bicycle industry.
Join us on this multi-episode series as we press record and let Jim imbue his wealth of knowledge on conjured pieces of the past.

This is From the Dungeon.

Welcome.
