    Decent weight for an aluminum frame.
    A pretty good price for a 100% USA made frame.
    SS or geared dropouts. Great company to work with. You can get it in almost any color you want (for a bit more money.)
    Balanced 70 deg. HA.



    I enjoyed my demo'. A slightly slacker 70 deg. HA makes downhill a whole lot more fun than on other hardtails, but it flies uphill because it's simply a hardtail and hardtails climb well. It has a very respectable weight in the low 3lbs.

    Sinister hardtails (like the Ridge) dampen bumps very well, so they have a more comfortable feel. Big impacts still feel harsh, because it is still a hardtail. I could not feel much side to side flex, but a tiny bit to help it pinn corners (which it does well.)

    I may get one for XC racing.

    Handmade in the USA and comes at a decent price.
    The Sinister forum is a great resource (you can talk with the guy who made your frame.)

    Similar Products Used: At least for other "real" XC mtb's I have also owned a Marin Bear Valley (steel) and a Cannondale Rush. I've ridden many other bikes.
