    ISM Seat

    Who's tried one one for endurance/XC stuff. I'm intrigued by the design.

    I have. Put about 50 hrs on it and couldn't get comfortable.

    10-4. I was afraid of that. I need something with a big scoop for my small junk. Thoughts?

    Not sure if 1 review is conclusive, a friend of mine who rides quite a bit loves his and won't use anything else. I think it's one of those things that you need to try for yourself.

    I have one on my road bike and like it a lot. It takes some getting used to as your sit bones will be sore for the first few rides, but once that ends, it's heavenly. Heavy, though.

    I can't see using one of those on a MTB. They're primarily for Triathletes.

    Check out SQ Labs. Great design and excellent for endurance.

    SS cyclocross
    Full Sus 29er (Yuck)

    Stop asking how much it weighs and just go ride it.

    +1 for this method. I've tried a lot of saddles, no substitute for personal experience. I seem to do well on Specialized and Selle Italia's S3 models.

    I do, but it's in a different country so no easy access.

    Some forums have saddle swap threads, you might be able to pick up a used one for cheap.

    I use a PN1.1 on my MTB, wouldn't use anything else.

    That concept was developed for triathletes riding for long periods in a very aggressive, low time-trialing position with a forward tilting pelvis. Not designed for MTB at all... MTB is a very different application from what it was designed for. YMMV

    You do know they have different designs, including a MTB specific saddle and a large road range?
    The Tri specific ones have a sloped nose to allow for the pelvis to be tilted forward, where the MTB and road ones are designed for normal positions that you would spend time on.

    There are also other snub nose saddles that are gaining popularity:

    I did know that... my point was to the original split-nose design concept. It was designed to relieve perineal pressure for forward tilting triathletes riding in aero positions for long periods.
    That's a pretty limited market, so of course manufacturers like ISM are marketing differing versions of the saddle to other market segments.... and I am sure it works for some.

    Look, I'll be the first to admit that I am no saddle expert, just another guy chatting on the forum. My view is that the original design was a ground-breaking innovation in the Tri world... but in the MTB world, it's just a backwards engineered product to appeal to a broader market.

    They do make a mountain bike specific one, although I have no experience with it, I am intrigued though.
