I'm sure this has been handled elsewhere, but I got bored while searching... So, the Receiver of Revenue owes me about 10k. I think I deserve a power meter. I'm sure there is a whole thread on PM vs Wheels and all the other debates, but I'm ready to splash the cash on a PM. I've done quite a lot of research and based on my needs and budget, I'm happy to have a left side only device. Does anyone have any real-world input for me. I like the Stages, but am concerned that if I upgrade my bike, I'll need to change PM's if I don't buy Ultegra again. I like the Garmin, but am concerned about some fitment and durability issues. All advice gratefully accepted.
