touring with disks...frame strain.

HI everyone,

My wife and I are going on a tour this summer in Europe on our tandem which happens to have disk breaks other than fitting problems I was wondering if anyone knows whether disks put on any undue strain on the back end of the bike as the wheels, breaks, and bike rack are all basically fitted in the same area. I am not a mechanical person so I am just curious if anyone has heard of a frame breaking on a bike with disks that was also carrying a heavy load. I should add that combined we weigh under 250 pounds so even fully loaded we will probably be light than a lot of teams just going out for a day ride.

Why I'm on the topic has anyone used a Topeak super DX bike rack. I hear they are made to fit a bike with disks and just wondered what people thought of them.

Chris

If you are flying I would take take the discs off for the flight

Oh yes

In Europe we call them brakes

I personally have not heard of anyone breaking a frame

enjoy the tour, and if you come near me and I am not on the road then there is a bed and shower waiting

Front disc wheel are dished unlike rim brake wheels, which makes them weaker than they would be with rim brakes. Discs do apply braking forces differently than rim brakes as well. However, presumably the manufacturer of your tandem has considered this in their design. If you have any doubts contact them and explain your intended use as well as your touring load. They will be able to give you better advice than us folks on the net.
