Does anyone have current weights of the Dura Ace 9250 group set? I see the disc version listed at 2506.5 grams at one site. I'm debating a rim vs. disc build and trying to determine what the true difference in overall weight would be in two respective builds.

Thank you!

I wish I'd weighed the parts as I currently have both built up now.

The 9250/70 groupset are super nice. Shifting is much faster than 9150/70.

I much prefer my rim brake setup over the disc.

ST-R9270 - ST-R9250 = +120 grams
BR-R9270 - BR-R9200 = -97 grams (note BR-R9210 each is 10g lighter)
RT-MT900 pairs (176g), hoses and fluid in total would 40 to 50g heavier than two brake wires and housing (150g or such).

You can go to R2 and add up individual measured weights to be accurate. Chain ring size, cassette size, crank arm length, rotor size, chain length... these all change the weight and are often not compared apples to apples in listings.

Chain ring size doesn't seem so easy...

I find Shimano's listed weights to be spot on. Start with the weight for the correct crank length provided by R2 and then adjust for chainring size using weights provided by Shimano. It should get you really close.
