Road bike recommendations

If I was to get a pwer meter it would probably be the garmin vector, as I can get it at US trade price through a friend. I'd want to be able to change bikes and wheels fairly easily so the pedal based-ness of the garmin appeals.

It sounds like installing vectors is far from simple. You need precise torque. Yet, with no allen key end, you cant use a standard torque wrench.

Removing a shimano non-driveside crank arm is far easier IMHO.

Still you'd need to be running the same cranks. Plus once you have the right tool for Vectors it s aquestion of taking 15mins instead of 5mins. Which probably isnt important.
