I have bought Brooks B17 Imperial for my Fuji touring bike and would like to break in before taking it on a trip. Have read recommendations to reach 1000 km to make it fully fit. Right now it is winter in Norway, so I do cycle home using my road bike on Tacx trainer. Would it make sense for me to put B17 on my road bike and try to break in inside? Or is it bad idea since touring bike has likely different geometry?
