View Full Version : Why the angle on the rear fork legs?

Why are the rear fork legs angled? It seems to add complexity but I don't see the benefit.

Wouldn't two parallel arms work as well? Weight change would be minimal and appearance seems similar.

Do you mean parallel to the ground so that they connect with the seat back tube a few inches lower?
If so, yes that would work, but now you add more unnecessary tubing length and the resulting frame will not look as nice.

I meant parallel to each other so that they are not angled from the axle to where they attach the frame.

Would that make the whole recumbent longer?

I personally think the current design looks sleek because the frame follows the seat shape ( or vice-versa )

My vote is to go with your gut -- beauty is in the eye of the beholder -- if you think it will look better then by all means do it -- structurally it will make no difference so by all means do it and show us your results.

On my Bentech builds the stays are parallel.

From the point of view of strength and appearance they are fine.

One I built with disk brakes. The other had V brakes and that is where the problem starts because the fork of the stay is too wide near the rim to fit the brake. I got round it by welding in a short spacer tube at that location.

My take would be that the angled stay makes brake fitting easier. other tan that it is probably aeshetics.

Ok, I see what you mean. Yes, you could do that.
