Can someone explain to me how shimano spds work. I've got a set of ageing and heavy Time pedals in need of replacement and like the look of the new shimano XT. Can't try any out so hoping the fountain of knowledge here can explain how does the spring tension adjustment works. Does the release angle stay constant irrespective of where the tension is set? Presumably the amount of float reduces the tighter you have the spring tension? And finally i also presume the pedal is harder to get out of with higher spring tension? So if you like a fair bit of float then you have to run the pedals quite loose.
Tried Google but its so far failed me.

Yes

Yes

yes, if you tighten it right up then it can be difficult to get out although it's also difficult to get in.
from my experience the spring tension only adjusts the force required to release the cleat, the float and release angle remain a constant and there is no way of adjusting this.

No, actually.
The only adjustment is the spring tension. The amount of float is preset and is determined by the shape of the cleat.
Great ta. And if i understand correctly the float is free until you hit the release point? Whereas the design of the time/crankbrothers means that the force restricting the twisting motion of your foot increases as you twist further before it eventually pops out.

yep.
Thank you
