Reading and comprehension is not everyones strong trait, but yes, as pointed out by EKIMIKE, it is my personal opinion. Usually things like design, looks and comfort are. If you looked at any of the recent paint jobs that BMC has had on their bikes you would understand where I'm coming from. They are all quite sleek and this one just happens to be one of my favorites. Ok, back on topic...
As I mentioned before, a small mod had to be done in order to fir the large Rotor Q Ring to the Sram BB30 crank. Since the arm has increased in size there was a clearance issue when fitting the ring.
After some research, I found out that the only way to get things to fit was to cut out a portion of the ring. The goal was to remove as little material as possible so that stiffness of the ring is not compromised. Also, its very important to be sure that you know and have the right setting in mind as performing this mod will limit your choices a bit. Since I have ridden on the 3 setting for about 2 years now I decided to stick with that. Below is an picture showing the marked area that was removed.
I used a dremel to remove the small piece and then finished things of with a hand file. That way I had more control and did not risk getting extra happy with the dremel
Using the file, I rounded off all sharp edges so that they don't scratch the carbon on the crank. A tiny bit of the pin that sits right behind the crank arm also had to be filed of as it was touching. I was able to get the cut close enough so that you can insert a sheet of paper. I will probably apply a piece of clear tape in the area for further protection. Here is what the fit looked like:
Everything fit nice and snug.
and here is another image showing how little was removed:
After doing some riding on various terrain I will report if there are any flex issues. If anyone has the Aero version of the rings there should be no concern for flex as they are stiffer and removing such a small portion of material shouldn't cause any flex problems.
Thanks for the comments thus far and more to come....
