D-257 TN-II Team Marathon FEI Weight
To withstand the stresses of a four in hand the D-257 is built stronger and heavier than our heavy pair marathons. In addition to basic heavier steel construction the wheels come with 18 spokes instead of 12 and tires are 5cm wide in lieu of 4cm. The D-257 comes with a standard bucket seat, movable fore and aft and to the center or an optional single center mounted seat. The base model provides the required FEI 600 kg weight.

Optional Polished Stainless Steel
Stainless steel, chrome rolled steel (SAE 5140), is not only pretty, resist scratches and abrasions but is also lighter and stronger than low carbon rolled steel (SAE 1010).
“Stainless steel (chrome rolled steel) has about 3X the yield strength of low carbon rolled steel. Thus, for any given desired strength that is needed for an application, (i.e. shafts, or frame parts of a carriage), you can use a thinner gauge (and hence lower weight) of chrome rolled steel when compared to carbon steel. The mistake that I noted in the past was that most carriages were “over-built” in my estimation, by using the same gauge for both chrome rolled and low carbon steel. To be sure, the chrome rolled units were much stronger, but I never felt that the extra “crash and burn” durability warranted the heavier than necessary weight. I don’t mind training heavy, but I sure do like to compete light. By using a thinner gauge stainless steel you can maintain or increase strength and be lighter at the same time, the best of both worlds.” Ken Messner & “Welding Principles and Practices” by Raymond Sacks.
There are multiple possibilities to add stainless steel to your carriage. The following are several options for you to consider. If you don’t see a specific item you would like please let us known.
NOTE: If you would like stainless to reduce weight but choose to have it painted vs. polished the pricing is reduced.
The first option and most common, is adjusted by a small hand wheel which the navigator or groom operates. A small brake master cylinder provides hydraulic pressure to a small motorcycle type caliper which engages a brake disk attached to the fifth wheel. The second option of the hydraulic fifth wheel brake pedal is operated by the driver by means of an extra brake pedal that operates a small master cylinder to provide hydraulic pressure to a small motorcycle type caliper which engages a brake disk attached to the fifth wheel. This option, like the hand wheel operated by the navigator/groom is quite effective, the braking action is instant when the pedal is depressed and instant off when the pedal is released.
The wheel and pedal operated 5th wheel brakes are available together..
The “manometer’ permits you to set the desired amount of pressure on the fifth wheel for both the pedal operated by the driver or the hand wheel operated by the navigator.
The pedal operated hydraulic fifth wheel brake, which can help provide a straight rein back in dressage, is also available on Presentation carriages. Maybe just may be enough help to bring home the blue!!!
