This is a review of the 2011 Fourstroke Carbon FS01 Frameset. All that I can say is...WOW!!!! Point this baby where you want it to go, and its like a rocket. Light, and just feels good. Climbing it feels like my hardtail. With the Floating Pivot Technology, you can't tell if there is any pedal bob what-so-ever. It just feels like all of your efforts are trasfering directly to the rear axle. The geometry makes for precise steering, not squirely, but not real slack either. Great for XC, which is what it is designed for. The way it handles just makes me feel like a better rider.
Bike Setup: Mavic Crossmax ST, X-fusion Fork, Shimano XT, Race Face Cockpit, Avid BB7, Crank Bros Candy 3's, Maxxis Crossmark/Ignitor

Strengths: Ascends like a french alpinist on speed. Descends like an olympic bobsleder. Always feels solid under me-no flex. climbs better than an epic as it i fully active. Comparable to the maestro design on a giant Anthem or santa cruz blur. Pivots are solid-low maintainence
Weaknesses: Spendy, albeit worth every dime
Bottom Line:
After many years riding and working in shops, this is THE BIKE i've been searching for. I like long rides, usually lots of climbing (which i'm not the best at) and bombing it back down. This is the most efficient climber I've ever been on, and it's solid as a rock on descents. If thats your style, get a BMC.

Strengths: i do whatever I can to rotate s/mt, wissa, french creek, salisbury, american standard and cpl others in thorpe. wide range of trails and performs excellent in all. the well balance set up allows to easily manhandle it through anything at any speed.
Weaknesses: still looking .
Bottom Line:
it’s been almost 6/months of hard pounding on this thing and have made several adjustment along the way, but then again I ride fast, hard and by no means baby this beast. I can’t believe the hope hubs…man what is with these things. Shocks have been perfectly tweaked and all of the bugs have been worked out. After a couple of weeks off do to the ridiculous weather we’re looking forward to getting back in the saddle after the 1st.

Strengths: Light, freakin gorgeous, smooth.
Weaknesses: high standover
Bottom Line:
I bought the frame from a guy who went to a 29er, it has a couple of dings that do not effect the ride. He was offering the frame and a nice fox fork for $1000, on a whim I offered $300 for the frame only and he went for it. This is the fanciest piece of technology I have ever settled my butt on. The DT swiss is amazing, it completely smooths out small bumps at speed. I am looking forward to finding a decent fork and xc wheelset for it, getting the weight down, and really letting fly. I don't have any experience with xc full suspension, but I love how this frame makes me feel.

Strengths: hand picked everything. custom built from Arounkone (my buddy) at pureenergycycling.com excellent service we took our time
Weaknesses: none yet. considering i haven't picked it up yet. but will gladly keep you posted.
Bottom Line:
After doing all the research we have built a lean mean racing machine coming in at 23lbs & change. I wanted to go even lighter but they wouldn't let me.
Excellent Racer and XC haul asser.
you get what you pay for!

Strengths: Ridged, light enough, no creaks from the bearings.
Weaknesses: stand over height
Bottom Line:
Had a 07 Fourstroke and busted the rear carbon triangle and got an 08 in replacement. It took awhile to get the replacement frame. The new 08 changed to an AL rear triangle and replaceable pivots/bearings. The rear DT shock sucked air into the dampening oil so I got an Fox RP23 for it. It wil bounce if you stand up and mash. The technique is to spin a circle "lifting on the up stroke" while standing over short punchy rollers. I've won a couple expert races on this bike.

Strengths: Stiff, responsive, smooth, light (for dual susser) tell me when to stop. This bike is pretty amazing!
Weaknesses: Yet to discover any.
Bottom Line:
I bought the frame only and transferred my kit across. Initially I missed the dynamics of my hardtail but after the first ride I knew I'd made the right decision. I bought this for the Cape Epic and in the last few months my training has taken on a whole new level of fun and joy as I've got to grips with the dynamics of such a well sorted dual susser. This thing takes some big hits on very rocky singletrack and still begs to be taken a bit harder. So far nothing has conquered it (arguably not even me) and I am one very very happy MTBer!
This is a lot of money for a frame, but if you really want value for money this is the baby for you.
Bike Setup: SRAM XO & X9, FSA carbon crankset, Avid Ultimate brakes, KCNC seatpost, skewers, jockey wheels (you get the picture). ZTR Olympic rims with Maxxis Crossmark tubbies. Easton carbon handlebars and stem.

Strengths: Climbing and Descending. Very light. Stays glued to trail like none other.
Weaknesses: Expensive and hard to find--rare in U.S.
Bottom Line:
Best bike I've owned. And look at the bikes I've owned. Better than any of them.
Climbs better than any of them. For trail riding, you need a bike that can climb like a hardtail w/o being locked out. This is that bike. Virtual pivot is the way to go.
Descends better than an Ellsworth Truth or a Hi Fi carbon. I tried it w/ the 5 inch rocker links and liked it even better. Feels like a Blur or the Genius MC ltd on the descents.
If you can find one, buy it! Used they normally sell for cheap because not that many people know about them so there's not a big demand for them. So value rating is 5+. Since its the best bike I've owned, overall rating is also a 5+.
Target market: people who don't want to make compromises between an XC race bike and a trail bike. (I just ride trails, but every ride w/ my buddies is a race. We drop the hammer. And we race at the local races at Sundance resort a couple of times each season. I took first in sport this year.)
Weaknesses: Stand over height could be a little lower to provide a better frame fit
Bottom Line:
Before purchasing I was a little confused over brand / design, I borrowed the same spec bike from the local bike shop and made a simple decision to buy. This bike is not cheap but well worth the outlay. I purchased the frame a few months ago and built a top draw machine to race marathons and XC races. To date the bike has proved a dream. The suspension is stiff and responsive, the bike is a lethal weapon on descents. I have successfully put the bike through a number of trails were my hard tail and NRS would have failed. Big and small bumps are all dealt with in the same way, the suspension eats them up. I have not used rear the lockout as the bike has no bob once the pressure is correctly set. I am 5.74 feet and have to ride a 19inch frame, as stated the stand over height could be a little lower. Remember BMC is Swiss, they have the Alps the bike must be a responsive!
Strengths: outstanding feedback at highspeeds, smooth and controlled slides, climbing, Stylish, unique
Weaknesses: price. U get what U pay for!
Bottom Line:
Its tough to pull the trigger $$$ wise, but if cycling is a significant part of your life, don't sit on your wallet. Ride something that doesn't have the chevy stigma and bump it up a notch. The ride and feel is off the hook!
Similar Products Used: Santa Cruz Superlight. I was reluctant to make the change. Although I really like the SL, I wish I had made the change sooner. The added 1 lbs is not noticeable and goes away by the improved handling. Little or no lateral movement.
