Selle Italia's Max SLS Flow is part of the maker's biologically tuned saddle IDMatch system. Providing a set of measurements gets you a number and, with SI's whole range having corresponding numbers, it should be easy to find a saddle to suit.
The firm also offers a no-quibble 30 day exchange, so if you buy a saddle and it doesn’t suit you can change it.
The SLS is extremely deeply padded and the fibreglass hull has a huge 105mm cutout. It makes for a very plush perch, ideally suited to more upright riding positions.
Indeed, our racier test riders found the SLS a little too plush – it's a saddle you sit in rather than shift around on. But if stiff saddles don't agree with you then the luxuriant SLS just might be what you're looking for.
