Kent Carlson's Sweet Parts cro-moly cranks where way ahead of their time, maybe 10 to 15 years ahead. Integrated arms, oversized bearings (one was even outboard of the BB shell) and tubular Cromo arms made the Sweet Wings a highly sought after crankset. Unfortunately Sweet Parts could not survive on the back of a high-zoot, really expensive, crankset. While they did offer a quill and ahead stem it was just not enough and by the late 90's Sweet Parts was pretty much done.
Recently Bikeman found a 175mm Road crank with 130mm Shimano chainring spacing up in the rafters. The crank is in outstanding, I dare say in nearly new condition. Complete with bottom bracket, the crankset weighs in at 520grams. Very light, even compared to today's 'light weight' Carbon Road integrated cranks. The FSA SL-K crank weighs in at 675grams with chainrings. Add some chainrings to the Sweetwings and you are right on target. Did we mention the Sweet Wings crankset is cro-moly?
The cranks achilles heel was the splined interface that held the spindle together. If the crank was going to fail, and quite a few did, it was the splines that would strip out. Deeper splines would have helped alleviate the problem but would have also required a thicker spindle thus adding some weight to the crank.
A few other companies, back in the day, produced integrated cranksets. Bullseye and the Tioga Revolver where two cranks using an integrated spindle but neither had the allure of the Sweet Wings.
