I’ve had three in 5 years (all on the same bike)- all with Ki:um rails. I bought them new (never spent more than £45 though, and 2 second hand with many miles of use for around £35-40 mark).
One white and black and two all black.
They’ve been the most comfy saddle i’ve used, however i’ve found that the covering used on the nose wares quite quickly – i think that they may have changed the fabric at some point in the last few years as the the newer two i’ve had ware the worst. It does depend on the shorts you use though….
this is 1st one i bought (in white) after 2 years use, you can see the colour is still pretty good:
you can just see the nose wearing through here:
tbh – the next saddle i’ll buy will be a brooks.
