I just ordered the Cannondale SuperX Di2 for the upcoming CX-season . I am really looking forward to receiving and racing the bike, but I need your expertise for answering a couple of questions
1) I need a power meter for the bike, but it seems that my options are very limited. As far as I can see, only Stages, Power2Max, and Srm make a power meter for the Hollowgram Si crankset which is on the bike. The SuperX has adopted the Ai concept from the Scalpel Si and F-Si mountain bikes. Since this means that the chainline is moved to the right by 6 mm, I strongly suspect that the Power2Max and Srm power meters will give an offset chainline if I fit them to the crankset. Has anyone else tried to fit a power meter to their SuperX (2017 and newer)?
2) Suppose I go the Stages power meter route. If I want to participate in flat road races or sportives in the Alpes, I will probably have to use a bigger or smaller chainring, respectively. The SuperX is equipped with a 40t Opi Spidering. However, I have not been able to find other sizes such as 36, 38, 42, 44, 46, 48, 50 which are compatible with the Ai Offset chainline. The only thing I have been able to find is the Spiderings for the Scalpel Si and F-Si mountain bikes, but they do not come in sizes larger than 34. Alternatively, I can find a spider compatible with the Ai Offset chainline, but I have not been able to find one which support 5 bolt chainrings with a 110/130 bcd (so I can use, e.g., CX1 rings) - only for XX1. Has anyone else been looking into using alternative chainrings and/or spiders for the SuperX (2017 and newer)?
