Fair Wheel Bikes is at it again. Our friends over at the Tucson, AZ shop that specializes in lightweight, high-end bikes and parts just got their hands on the new Shimano Dura-Ace R9200 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.

Shimano Dura-Ace 9200 Di2 Wireless 12 Speed Group actual weight crankset

The group starts with the crankset, weighed here as a 172.5mm length with 50/34t chainrings, and no bottom bracket. The Shimano Dura-ace R9200 crankset weight is 678.3g

This group shipped with a Dura-Ace 11-30t 12 speed cassette which weighs in at 222.2g.

The full Dura-Ace R9200 12 speed chain (which is the same CN-M9100 chain used for 12 speed XTR) weighs 268.9g.

Shimano Dura-Ace 9200 Di2 Wireless 12 Speed shifters actual weight

A pair of Shimano Dura-Ace R9200 shifters weigh 367.6g.

Shimano Dura-Ace 9200 Di2 Wireless 12 Speed derailleurs actual weight

Which leads us to the Shimano Dura-Ace R9200 derailleur weight at 93.6g for the front, and 215.2g for the rear.

Shimano Dura-Ace 9200 Di2 Wireless 12 Speed battery actual weight

To make it all work, Dura-Ace R9200 features wireless shifters, but wires that lead from the derailleurs to the battery. The Shimano internal Di2 battery weighs 52.2g, while the various Di2 wires and pieces weigh 21g.

Shimano Dura-Ace 9200 Di2 Wireless 12 Speed brakes actual weight

Saving the best for last, the Shimano Dura-Ace hydraulic brakes weigh 144.3 for the rear and 145.1 for the front with a 160mm rotor adapter. Note that this is with full-length hoses that usually arrive pre-filled.

And while Dura-Ace R9200 uses the same rotors as Shimano XTR, here they are on the scale at 87.5 for the 140mm rotor and 107.3 for the 160mm rotor.

Thanks to Fair Wheel Bikes for sending these over! We’ll have another post from them soon with a very special build that uses a little bit of everything to create a very light gravel build…

It appears so, by 50g compared to Tyler’s weights on RED (2423g Shimano vs 2373g SRAM). The crankset is the biggest difference with the RED 35/48t with power meter at 575g, while the Shimano is 678g.

32/56t chainrings? Besides the fact that that wouldn’t even work, how about 50-34t as visible in the image (also in the correct order).

Zach Overholt How do you get to that figure ? Go to your ref and add the SRAM chain (114links) is like 2479gr and not 2373g… So about 50gr for shimano. And from another source the brake lines are already filled The shimano crank is porky as with powermeter SRAM will likely be lighter. Dropped that already in favour of rotor carbon crank with pw2m (+-600gr)

I realize you fixed the typo, but why does Shimano even offer a 56t chainring to the non-pro public? Anyone who is truly capable of utilizing 56t ring is most likely getting them for free. It would be nice if they offered other chainring tooth counts so you could pick your own gearing. Useful big rings like 44t to 49t options. Probably my biggest complaint about Shimano is their effort to micromanage the use of their products.

@Eggs, per bike.shimano.com you can get 50/34, 52/36 & 54/40 Dura-ace chainrings. Didn’t see the 56 that upsets you and that 50t is realllllly close to the 49t you want. If you want smaller rings for groad get GRX? Why do you want such small big rings in a ROAD group anyway when you have the choice of two front chainrings???? Bases covered it seems.

@eggs for flat to flat ish races, I love the 58 and 60T rings that I’ve gotten from Rotor and PCD. It’s a shame that everyone is focused on being a weight weenie instead of doing what gets them down the road the fastest.

The video “Dreambuild Orbea Orca Aero” on youtube has all the weights too.

Yeah, anyone looking at rings in those sizes(44-49t outer ring) is either spinning intentionally(that’s fine), or doesn’t change gears with overall tire diameter. These top groups are made basically for 622×25-32mm tires. If you run much greater effective diameter, you should look elsewhere.

What was the weight of 2013 Red22 again? ~1700g?
Sorry, but 500g+ don’t let me switch to electric shifting jet.

Why is every thread of Shimano product plagued with defensive SRAM users? We don’t care! You can keep your plasticy dumbed down nonsense and you opinions to yourself – DA is a top end race groupset no a fatty masters clubrun SL7 wet dream.

It was 1800 grams, but didn’t include shift housing, brake cables, brake housing etc… Realistically it was about 1900 grams. But regardless you’re comparing a mechanical 11 speed, rim brake groupset to an electronic, 12 speed disc brake groupset. The weight difference that you are seeing is primarily from the brakes and the not the electronic aspect.

As far as that comment earlier a out a 56/34 chainring, how it wiuld not work and why. Actually when I was at FSA we got request for this combo almost weekly. FSA does have an Energy/SL-K &K Force version of this combo for the modular cranks being tested by top pro riders now. I’m not giving amything away as observant people will have seen the part numbers already.
Riders in areas like Seattle wamt these. You have hills and mountains all over so you need a 34. However you wamt to pedal with power and not just spin down the other side. The advancments in CNC, Design & materials. Allow you to make ramps and pins on the large ring that will make up for what the derailuer will not.
