Hey Robban from Sweden....Your best bet is to talk to the guys over at Bender. They are very knowledgeable and friendly. They will definately take the time to help you figure out exactly what you need, no matter what the application. If your riding in the mountains...be sure to tell them the elevation you typically ride at for optimum set up. www.Benderracing.com or email Mike with tech questions at www.mike@benderracing.com or call in the states...585-937-6837. Hope this helps!
