Bought a Selle Italia Genuine Gel saddle last year - and may have put like 4K on it so far (fall and spring) - and it is falling apart (is coming apart along the stitching - I can now see the yellow padding inside the saddle). I had another Selle Italia (came on a bike I bought) and it didn’t fair much better. I like the saddle but don’t want to have to replace my saddle yearly. Is this a defective saddle or about typical?
