Looking for weights of Shimano left crankarms, specifically 6700/6750 and 7900/7950. Even if you only have one of the two, please post weight if you can (and include arm length).

Thanks in advance!

I own older dura-ace and 105 :

7800 / 172.5 = 180 g

5700 / 175 mm = 200 g

Also Stages-Related ...

anyone can also provide some weights of SRAM crank arms?
Here comes the first one:
SRAM Rival 2010, 175mm, GPX is 219g

Anyone can provide some data of Force/Red (maybe 175mm too)?
