I have a 2015 Cannondale Synapse - specifically, this one: http://www.swiftcycles.co.uk/334/products/2015-cannondale-synapse-carbon-105-6-road-bike.aspx. I would like to add a power meter, and power2max looks like the best option to me because it looks very universal as I upgrade other stuff. Over the next few years, I'm sure I will replace my wheels, maybe my pedals (considering Speed Play) and almost certainly the bike itself. As power2max spiders off the chainset, the only thing this power meter would limit me to is crank and chainset - and I'm happy to stay with a compact at the moment.
The Synapse as far as I understand has a BB30A bottom bracket, which I believe means that the crank diameter has to be 30mm. 24mm cranks seem to be compatible with more frames, so I am looking to instead purchase the following:
- power2max Type S power meter with 110mm BCD
- Rotor 3D24 cranks with 172.5mm crank length (matching my current cranks).
- Keep my existing chain rings & pedals (Ultegra pedals)
- Rotor BB30to24 bottom bracket
- Unsure whether or not I need to purchase chain ring bolts - can I use my existing ones?
As far I'm aware, that should all work with my BB30A bottom bracket. Before I shell out a load of money, I just want to make sure this is all correct - look forward to hearing what you all have to say. Thanks!
