As you say, it’s a tremendously personal choice.
Through a combination of boredom and inquisitivity, I bought a whole heap of saddles to try just to get even a faint impression of what I liked.
The Specialized Power saddles are in the region, but…
The saddle I am currently using and really like is a Toseek Carbon hollow, from eBay. Yours for the princely sum of £16, tips the scales at a barely there 102g and once you get over the “Er, it’s just carbon fibre and no padding at all”, for me it fits perfectly and never ceases to surprise me how comfortable it is over time.
My initial description to my cycling friends was “It’s not the most comfortable saddle I’ve ever sat on, but I think it is actually the least uncomfortable”.
To explain that, the very first time I went to get on the bike with it on was a shock. I tend to mount with one hand on the saddle and one on the bars as I swing my leg over. As soon as your hand touches the completely solid saddle it feels odd.
You sit on it and think “Wow, that’s firm” but it’s not uncomfortable, it’s just firm.
Where it comes into its own is that an hour later it still feels firm, but with absolutely no pain or pressure at all. It fits my sit-bones perfectly and with no gel or foam to displace, bunch-up and for your soft tissues to then rub against it just remains constant for the whole ride.
Imagine a comfort chart where a padded saddle starts at 100%, but an hour in it’s down to 85% and three hours in it’s down to 70% with some hot-spotting on sensitive areas.
This starts at 90%, but then just stays there hour after hour after hour.
I think the best advice is to try saddles at a bike shop, especially if they have loaner models, but for me a super cheap all-carbon (rails too) saddle from China seems to have won out.
Forgive the background mess, but I even think it’s quite pretty.
