Our new bike came with Dura Shifters and derailleurs, but an Ultegra level cassette.
I'm wondering if this is a cost savings measure, on an item that doesn't stand out, or whether it's intentional for superior toughness/wear.
I have a Dura Ace cassette, not in regular use, with the same gearing that I could swap out, and save about 60 grams. But I'm wondering whether I'll get excessive wear on the Ti cogs under the load of a tandem.
Anyone running D/A cassettes on their tandem?
