I've been toying with the idea of mounting a dynamo on my REI touring bike. Model is ADV1.1 and it has a steel frame.
Dynamo attaches by a mechanism that clamps onto a seat stay and tightens with two bolts, but I also recently got spooked by stories here and here that similar mechanisms for kickstands run the risk of crushing the chain stays.
I don't have much experience with mechanically modifying bike frames, so how generally concerned should you be about fixing things to or modifying a bike frame for fear that it is damaged or weakened significantly?
And how much should this concern vary between different brands or types of bike, i.e. touring, mountain bike, etc?
Should the concern for kickstands and the chain stays carry over to the dynamo scenario?
