I don't understand how that could be.
I'll also say, as a user of a Fluid2, that a 53/19 at 88rpm is probably not much power at all.
I don't know either. I completely reset the computer and it is now reading as it should. As someone else said, it should be around 21.4 for 53x17 at 88 rpms and it does now. Perhaps speed was set for kph instead of mph and I just couldn't tell...the letters are so small on this particular cateye and my eyesight isn't so good anymore. I'm going to warm up tomorrow and try the 53x17 at 86-88 rpms and see how it goes. I'm guessing that 53x19 at 88 rpms is somewhere north of 250 watts.
