Actual Weights: Fair Wheel Bikes weighs the new Shimano Dura-Ace 9200 Di2 Wireless 12 Speed Group

Tips & Reviews

Fair Wheel Bikes is at it again. Our friends over at the Tucson, AZ shop that specializes in light weight, high end bikes and parts just got their hands on the new Shimano Dura-Ace 9200 Di2 12 speed group. And since we’ve only been able to test it out as a complete group, Fair Wheel sent over pics of their group on the scale.

Since we’ve only seen it built up, that means we also haven’t seen the gorgeous presentation box the new group arrives in. Sure, it’s no briefcase like the Dura-Ace 25th anniversary group arrived in, but this is (probably) more recyclable.
