Distinguishing features

https://www.bicyclebluebook.com/value-guide/product/92890/ The OCR 1 aluminum frame and carbon fork, high end, Shimano Ultegra drive train, except for the Truvativ crankset and a Shimano 105 front derailleur. That Ultegra kit included a 9-speed rear cassette and the Truvativ crank sported a 52/42/30 tooth triple front chainwheel, something you don’t see any longer. Most triples today are low-end or midrange, and have become increasingly rare in an era of compact doubles with 11-speed rear cassettes. And unlike similar bikes today, the OCR1 included braze-ons for a rack.
