>>1154914I don't have a power tap (broke college student) and use the cranks in the pic. I have done starts at my college's spin bikes and held 1200 watts for 5s. 30s I would have to guess around 850. My weight is 73 kg. Too lazy to do the math since that's all I do lol. Hellyer is a pretty nice velodrome and is run by very credible people.
