I'm going to be upgrading my bike from Dimond Brilliant to Marquise and given I'm now a few years down the road from the original purchase and racing longer distances does it make sense to look into a larger fame for any reason? Or if it aint broke dont fix it?

I'm currently on a size small with a PD Aeria cockpit and not having any issues. I'm now pretty much 70.3 or 140.6 only and my current bike/fit is comfortable, allows me to turn out quality times and run well off the bike. I'm asking my fitter and Dimond these same questions so any thoughts are helpful for me to evaluate and know what I need to consider or be aware of down the road trade-off's I'm making.

I'm going to be using a Vision Metron TFA cockpit on the new bike, I'd imagine its 'easier' to start small and then adjust a size 'larger' within the cockpit than the other way around. But I'm really not into my fit other than, it works, i'm happy, dont mess with it.... thus I'm asking people who might know better and have better information.

I've attached the Dimond sizing chart, my 'optimized' fit at my last Retul fitting, images from the fit and a race image if that helps. Yes, I need to get my head out of the wind.

I'm not looking at any other bikes and I get an amazing deal on the Vision bar so financially it makes very, very little sense to look elsewhere

Thanks in advance!
