{{Ergänzung|Artikel von 1997|Das konnte [[Sheldon Brown]] kaum voraussehen, dass die Arai Trommelbremsen seit 2008 nicht mehr hergestellt werden. Die Produktion wurde eingestellt und es scheint so als ob es keinen Nachfolger oder ähnlich adäquates Produkt am Markt gibt. Wer Glück hat, kann gelegentlich gebrauchte Exemplare bei älteren Tandems finden oder bei den üblichen Plattformen im Internet gebrauchte Arai Bremsen kaufen bzw. ersteigern.}} | {{Ergänzung|Artikel von 1997|Das konnte [[Sheldon Brown]] kaum voraussehen, dass die Arai Trommelbremsen seit 2008 nicht mehr hergestellt werden.

Für ein schwer beladenes tandem in hügeligem Terrain benötigt man also drei Bremsen: Zwei an den Felgen und eine an der Hinterradnabe. Aber wie kann man drei Bremsen mit zwei Händen bedienen? | |||

One traditional solution has been to use a special brake lever for one hand that pulls two cables. I don't recommend this setup; here's why: | One traditional solution has been to use a special brake lever for one hand that pulls two cables. I don't recommend this setup; here's why: | ||

Some teams set up the hub brake so that it is operated by the stoker. This can be a good solution for some teams. The drum brake doesn't normally need to be applied very suddenly, so if the stoker operates it when the captain asks for it, everything is fine. | Some teams set up the hub brake so that it is operated by the stoker.

===Schleppbremse mit Reibungsansteuerung=== | |||
The most common, and most satisfactory system is to set up the rim brakes, one to each conventional brake lever, and operate the hub brake by a friction-type derailer shifter. This may be a "Barcon", a mountainbike-type thumb shifer, or a Sun Tour Command Shifter. | The most common, and most satisfactory system is to set up the rim brakes, one to each conventional brake lever, and operate the hub brake by a friction-type derailer shifter.

A friction-type shifter allows the captain to set the hub brake to apply the desired amount of drag, even once he or she has let go of the hub brake control. the captain then uses both hands on the rim brakes to modulate the bike's speed, and to stop if it becomes necessary. | A friction-type shifter allows the captain to set the hub brake to apply the desired amount of drag, even once he or she has let go of the hub brake control. the captain then uses both hands on the rim brakes to modulate the bike's speed, and to stop if it becomes necessary. | ||
===Vorderbremse/Hinterradbremse=== | |||
On a conventional solo bike, the maximum braking force is created when the front brake is being applied to the point that the rear wheel is just about to lift off the road. Since, the rear wheel has no traction in this condition, the rear brake contributes nothing to maximum braking. | On a conventional solo bike, the maximum braking force is created when the front brake is being applied to the point that the rear wheel is just about to lift off the road.
