This happens because the added weight resists motion and will fight you every time you try to change your direction of rotation or speed of rotation. This means slower to get up to speed, slower to stop, and more force on everything that powers the wheel including the chain and axles.

I like the creativity to get the center of gravity lower, but I really think you should bring alternative wheels if these give you too much troubles in competition.

We had time to do some decent test driving, and mobility did not seem to be an issue. It was every bit as fast, if not faster than I expected.

That is a video of us driving, and if it seems a little slow to you, this is all in low gear. Unfortunatly, I didnt get any video of it in high gear, but trust me, for this game it is plenty fast.

Thank you for the advise though, I personally had no idea about wheel weight affecting mobility, however I am sure people on the drive train team took this into consideration when designing the wheels.
