As a pre-Christmas present to myself I've ordered a 12-month subscription to MBUK. Along with it I get the saddle mentioned. Never used one before and don't really see any reviews online. Are they decent/comfy or should I just put it on eBay and buy something else
My bike is a Trek slash which still has the standard Bontrager one which is pretty uncomfortable anything north of an hour. So, it'll be better than that if nothing else.
It's impossible to recommend saddles as everyone is unique, and what might be comfy for some is agony for others. Everyone I ride with uses Burgtec Cloud saddles, I have one and think it's the worst saddle I've ever sat on, excruciating, like sitting on a hatchet.
Just try it, see if you like it. If not, sell it, try something else.
As has been said, everyone is different and you need to try loads to find the best one for you. Or sell it to pay for your subscription then go to your LBS and get 'fitted'...
This is a great article about saddles and what you 'should' be looking for (https://www.bikeradar.com/advice/buyers-guides/how-to-choose-the-best-saddle/). It'll narrow it down, but you'll still need to persevere with trying them out.
I went through six saddles on my gravel bike that were broadly similar before finding the one that felt most comfy - and it wasn't the most expensive or fanciest name either.
