any difference here?

 

Yes. There was a thread about this.....
The ITR crank has bigger balance weights and is therefore heavier I think.....

 

I think there might be a unit error in one of the pdfs because the GSR crank weights 15.5 lbs and the ITR cranks weights 15.9 kgs. I believe the GSR cranks is suppose to be 15.5 kg and not 15.5 lbs(~7 kg). I weighed my ITR crank and it came out to roughly 36 lbs on a bathroom scale, but never took time to weight the GSR crank. I really don't think there is 17 lbs(~8 kg) difference between the cranks.

I got the specs from http://www.grand-am.com.


ITR crank 15.9 kg or 35.0535 lbs
GSR crank 15.5 kg or 34.1717 lbs

The GSR is roughly a 1 lbs or ~.45 kgs lighter .

Can anyone confirm this specs for correctness ?

I believe you guys are right. The GSR crank is lighter.

 

ITR crank is heavier. If you search, there was a long thread about this fairly recently.

 

 

Hmm, the area those arrow point to aren't really the 'counter weights'. The counter weights are opposite the rod connection, usually with drill holes (when they balanced it).

Well you're sort of right. When you look at the pics, you can see that the GSR crank has much larger arches than the R. The arches on the GSR crank extend out to the counter balance.
