Hello, I am a newbie. I recently purchased a new Truvativ X9 BB30 crankset and tried to install it on my new frame. I don't know if the bearings that came with my crankset is the wrong size. The crankarm will not go through the bearings. I tried tapping the crankarm with a rubber mallet but still would not go through...it's just a very tight. Is this normal on a BB30? Is it suppose to be like this? I did not want to hit the crankarm really hard or force it in. I am afraid that if I did get the crankarm through that it may get stuck on the other bearing on the drive side. I have installed a GXP crankset on my other bike before with no issues. Please help. Thanks
