Fork question for DW
Hey Dave! You’ve pretty much dialed in optimal balanced rear suspension for bicycle and possibly motor vehicle rear suspension dynamic anti-squat with bump compliance. I think there’s some room for enhancing integrated ride height and shock mount rate adjustable tuning in the dw-Link rear suspension design. I imagine you’re not done advancing the dw-Link. Although the current dw-Link has set the rear suspension standard of quality for this decade if not longer.
Do you have any thoughts on possible improvement for bike front suspension?
Air springs don’t work as well to control dive and wallow as linear coil’s near linear rate of telescoping path. Air spring is much more progressive, and needs more compression damping with the tradeoff of associated loss of bump compliance to slow and reduce brake dive and wallow.
Seems like the linear path coiled telescoping fork would be hard to better or else MotoGP or Moto-X would have done it already.
Even F1 or Dakar or Baja buggies would have improved on the linear front suspension rate already. But like a very light weight or female bicycle rider, cars have a much lower center of gravity so dive and wallow isn’t so large an issue as it is with average to heavier weight harder bicycle riders experience.
A roller bearing flat faced telescoping fork could reduce platform like bushing stiction significantly. The Canondale Lefty has this roller bearing design with progressive with air spring, but it’s not been done with linear coil on a bicyle The exception is MotoCxyn roller bearing telescoping fork design using coil for a MotoGP level performance limited production sport bike).
A pivoting linkage with a non-linear path may provide more compliance and modified spring and damping rate and brake induced anti-dive.
Are you working on anything for alternative front suspension?
Happy New Year!
