Jim,

I don’t need a power meter ? I do need a power meter ? I don’t I do -I really do and I suggest if your up in the air about it then you do too. When you balance the power output when cycling not only do I go further but I end up fresher and less tired. I’m new to the sport of cycling and have a low ftp ( which is getting better) by controlling the applied power near to my sweet spot I’ve raised my cruising speed by around 3 km/hr. Not fantastic but I’ve only used my power meter over a month. Best setting ( for me) has been a two sample setup of 3 sec and 10 sec. Holding my power constant over that range has been beneficial for me. Friends have a variation on that but one has to research and try what’s best for them

Not cheap, but probably the best value power meter you can get. Top quality and very easy to install (though you may need a crank installation tool depending on your crankset, e.g. a "Shimano Crank Installation Tool for HollowTech II"). Integrates seamlessly with my Edge 830 computer, and has added a whole new dimension to my training!

Q & A

5 questions answered

  1. Is this compatible with the Shimano 105 7100 groups? On 4iii's website it doesn't appear to be but I can't figure out why not since I thought the left side cranks were the same...
