So DR continually goes on about the value of a power meter, but I have a Trek flat bar roadie, with FSA vero cranks (170mm). I'm unsure as to whether I can get a compatible stages one for my cheaper style crankset. Then again, a 2nd hand power tap goes for around $800 (less than a new stages) on eBay.
Any thoughts pedal gurus? My Trek is a pretty good roadie for an entry level bike, just not sure whether it's worth the money/effort to do, or how the best way is.
Thanks in advance. Lemme
