    Finally got the F-Bomb finished. The color is raw and it truly is "raw". Out of heat treat and slightly cleaned up. No paint, no polish, no nuthin'. The final weight came to 38.75 lbs with a non weight weenie build. It is about 2 lbs less than my Highline which is impressive. Looking forward to the first ride.

    Those looking for a few numbers:

    Wheelbase: 46.25"
    Chainstay: 17"

    That is a sweet build man.
    I'm on one of the last production Sinister R9s, and wouldn't trade that bike for anything! Frank really knows his f-in business when it comes to welding quality DH frames.

    Now, I'm sure the floodgates of e-hate are about to open up with all the "omg, not another IronWhores Yakuza" comments.. but all that BS is coming from people who have never even seen a Sinister DH frame in person, much less actually ridden one.

    Enjoy it!

    Yep you nailed it. Every bike nowadays looks like something else. "Looks like" does not equal "rides like". I am super stoked on how it came out. If it ever stops raining I might actually be able to get on the thing. Looking forward to the initial ride.

    Sick.

    What's with the twist shift haters? I think it is far superior compared to triggers in every way. Less weight, simple design, less things sticking off your bars to smack knees / grab clothing, faster shifting, more natural feel... only thing I'd change is to just cut down a regular ODI grip and lose the inner lock ring. The shorty lock ons are a bit too narrow for me and I didn't like the feel of the inner lockring under my hand. Also, the smaller grip cover option mates perfectly with cut down Ruffians (in diameter).

    Do you still have the Highline?

    the frame weight without shock or spring (with all hardware etc.) is under 6.5 lbs.

    there are a couple running around at 36 lbs.

    Agreed on the shifters. I have been running grip shifts for at least 15 years. Just love them. 3 moving parts, slim, multiple shifts up or down at once, etc. The X-9 is the best feeling shifter yet. I don't mind the inner lockring. I guess I am just so used to the feel.

    No I sold the Highline frame and swapped the parts over. Saved almost 2 pounds. Amazing. Even with a semi-heavy build it is under 39 lbs. Cranks and wheels are heavy but overall the build is indestructable. In fact this is the 3rd frame these parts have been on. I still am waiting to get out and get the first ride in. It rains everyday I am not working.

    Nice looking bike, I'd never seen that frame built up before but it looks like a nice FR setup. Amazing that your bike comes in under 39lbs even without running super light parts. That is one light frame. I have a Highline that I have spent a fortune on to get the weight down while keeping it beefy and I'm still over 38lbs.
    Have a nice ride!

    Yes the frame is insanely light. I remember pulling it out of the box and thinking something was missing. But there are no shorcuts on the frame at all. The thing is stiff and solid.

    You've angered the Turner Gods.

    At least some lucky fool got a Highline out of this.

    I like the raw look though.

    if any of the manufacturers were stoked on their frame weights, they would be posting them. It seems that all the technology and effort went into high volume AM bikes at most brands and their DH programs lost focus. I took the fact that riders were buying AM bikes for DH that people wanted light DH bikes. People that raced AM bikes commented on flex and fear. We addressed these issues and released a rock solid, ultra light DH rig.

    I am pretty sure all the gods are pissed.

    Love the build! You have me thinking about running a grip shift on my next bike. I use one for the FD and love it, but maybe for the RD next time??

    Holy crap Frank forget DH, that's my new xc bike. My DNA frame weighs the same as that.

    Any idea if the frame would work well with an air shock like a Rocco, or maybe one of the new rock shox piggy back air shocks. Just bouncing weight weenie ideas around in my head.

    There's a link out there for Frank the Welder's flickr account, and there are pictures and video of people STANDING on the swingarm without any flexing. Truly ridiculous that something that strong is that light.

    Say what you want about the aesthetics (I have, I still don't think it's as beautiful as the R9), but functionally speaking, i.e. what really matters, the thing is a marvel.

    The video of the frame standing is awesome. Saw that a while back. I personally like the aesthetics of the frame. What I care about most is that the bike is stiff, flickable and rides well. If it ever stops raining I will get a chance to ride it.

    those little bikes are sick, I have ridden one quite abit, I really like it. Curious, how is the alignment with the rear shock? Make sure it isnt binding up in the shock. The 3 I have seen had the rear eyelet off set from the front eyelet by about 1/4" to 3/8". Started to kill the vivid bushings. Pop the shock out quick to check! Sweet build too, havnt ridden one with a totem!

    Interesting. I spoke to Frank to let him know that the tolerance of the lower shock mount was tight in that I had to sand a bit off to get the lower shock mount to fit. But didn't appear that the alignment was off at all from top to lower mounts. Once I was able to get the shock in the lower mount it lined right up to the top one. He did mention that he has a tendency to make the tolerance tight. I have been working at a shop for 15 years so I had no problem determining that it needed a touch of clean-up.

    What is bothering me is that the spring feels like it does not fit correctly in the shock. It feels like the spring has movement within the adjustment sleeve no matter how tight I adjust the compression. It seems like the diameter of the spring is a bit small for the retainers/adjustment sleeve (whatever the 2 pieces are called) and it moves slightly. By slightly I mean when I grab the spring i can rock it slightly within the sleeves. I tried flipping the spring but it does not help. I guess as long as it doesn't flop around it should be OK. I will give SRAM a call just to check.

    I haven't ridden it beyond the driveway test so I don't know how it will feel just yet. Yes I am in RI so it has rained everyday for the last 45 or so. Sucks.
