It looks that the Strida leather saddle is actually made by Gyes in Taiwan (http://www.gyes.com.tw/Saddle.html), typical from the Gyes saddles is indeed the ‘wave’ in the middle of the bridge between the springs.
Gyes makes a lot of different models, inspired by the Brooks saddles. From the comments I could read on various forums, users are very happy with their purchase. Gyes saddles are often cheaper than the Brooks ones.
According to this site (http://swhs.home.xs4all.nl/fiets/tests/zadels/index_en.html), Brooks made the springs stiffer on the B67 and the Flyer in 1999, by increasing the wire diameter from 4.55 mm to 4.95mm. This made the springs less effective as they now only soak the big bumps.
From the pictures on the Gyes website, it looks like that the outside diameter of the springs on their saddles is bigger than the ones of the Brooks saddles. Assuming that the wire diameter is the same, it would mean than the Gyes springs are softer.
Brooks Flyer:
Gyes GS-16 (Flyer equivalent):
Does any one have both saddles (Brooks B67 or Flyer and Strida ST-SDL-003 or Gyes GS-16)? If yes, I would be interested to know the various spring dimensions (wire diameter, spring diameter, length) of both models.
I am lightweight and that’s why I am interested in softer springs
