Whats the real deal with power meters for mountain bikes? Ive seen prices ranging from a few hundred bucks to a few thousand, and Im not buying the hype that you need to break the bank to get accurate data. So, whats the most affordable option out there that wont leave me feeling like Im guessing my way through a ride? Are there any viable alternatives to the big-name brands thatll give me the data I need without taking out a second mortgage? And dont even get me started on the whole accuracy debate - how much precision do you really need when youre bombing down a singletrack trail or climbing a grueling fire road? Can someone please cut through the marketing BS and give me the lowdown on the most affordable power meter option thatll get the job done?
