Ritchey, which I think are owned by Scott?really? they now own syncros too, I was looking at the syncros fl carbon forks but couldn't stretch to the £400+.
Rigid Forks... Steel Vs Carbon
Mostly, but not totally true. Materials vary in damping properties or levels of resonance just like they vary in stiffness. High frequency vibration or 'buzz' resonates less / disipates faster in a carbon structure than a steel one. But low frequency vibration - brake or bigger-bump flex- will be more about the overall stiffness of the fork than the material. Generalising and I'm not saying everyone will feel a difference in the fork material beyond basic stiffness, but if you can't make a good bell or a tuning fork out of carbon fibre the same lack of vibration retention should be true of carbon bars or forks.
Apologies for the snarky response. Bad day.
This was what I should have replied with and thank you for clarifying.
I doubt that most people will feel the difference between the residual oscillations of steel and carbon. I would think that it is the initial displacement that dominates the "feel" of the fork and this is mainly dictated by the diameter of the tubing involved. To give an example, a surly fork, despite being longer, will feel stiffer than a p2 fork, the same principle of stiffness varying with (approx) square of diameter are behind the lefty and SUB forks. The difference in the two is predominantly in the later oscillations - the ringing as it were - which is a small vibration, vastly masked by subsequent impacts.
FWIW, my own personal preference is for steel but mainly due to failure modes - I have bent P2s when a carbon fork would have snapped.
Good thread this Mark. Am currently building a rigid 29er and humming and haring between Carbon Exotics and Steel Salsa forks.
for those claiming more flex = more damping...
Carbon fibre tennis racquets are stiffer than the old aluminium ones but damp the vibrations much better. Same with modern composite axe handles.
Flex does not equal damping. Damping is the ability to dissipate energy. Flex is related to the stiffness of the material and the structural design.
I've got a set of carbon Exotics- they're light, and seem strong enough, they've been beaten about. They also seem to be exactly the same as at least one other far more expensive fork mentioned in this thread
They flex mentally on the brakes though- I combined them with an Airotor and watching the forks judder back and forth was pretty alarming. So I stopped looking.
