Dogma F8 Zero Setback Seatpost Gloss Carbon, One Size

Early photos of Froome's matte-black prototype F8 frame revealed just about everything that's available on the "stock" version, minus a few choice components reserved for the likes of Team Sky riders. Such is the case, or should we say was the case, with his neutral Air8 seatpost. Well that's not the case anymore, as the Dogma F8 Zero Setback Seatpost has officially arrived. Made with the same FlatBack tube shaping that the F8 frame employs, this Air8 post wears an ovalized frontal section paired with a rather truncated back half, which was done to create a vacuum that eliminates turbulence. A full carbon construction gets paired with a two-bolt carbon seat clamp, further ensuring weight remains as low as possible. The Pinarello Dogma F8 Zero Setback Seatpost is available in either a Gloss or Matte Carbon version, and it is only compatible with the Dogma F8 frame. Like the standard setback version, this model accepts both Shimano Di2 and Campagnolo EPS battery packs, but you'll need the mounting hardware, sold separately.

Monolink Seatpost

As a longtime saddle maker, Selle Italia knows that certain constraints limit design evolution. The key structural detail that squelches innovation is the existing side-by-side rail system. As one of the few true standards in the bike industry, it may be time for change. Selle Italia bucks the trend by creating their own rail design to make saddles that save you energy, and the Monolink Seatpost is the piece of the puzzle necessary to support it. While pedaling easier is certainly alluring, we're most impressed by the fact that this post design won't exclude fitment with existing saddles. It comes with a host of clamp parts to mate it to Selle Italia's Monolink saddles along with traditional saddle designs with round and ovalized rails. The fact that it can be used with every saddle on the market is thanks to the wedge-style clamp hardware. The system is based on the twin stirrups that form the top of the post. Empty they are parallel loops of 3k carbon fiber with their centers being offset from the centerline of the seatpost shaft by 25mm. The entire assembly is built in one piece with continuous fibers running the length of the post. The clamp assembly for Monolink saddles, with its vertically paired carbon fiber rails, is made of carbon fiber; and like the machined aluminum standard saddle rail clamp parts, it is secured inside the twin stirrups of the seatpost by engaging an aluminum double wedge to increase pressure inside the loops of carbon fiber to hold it all securely in place without slipping. The Selle Italia Monolink Seatpost is Glossy Carbon and is available in two sizes -- 27. 2 x 350mm and 31. 6 x 350mm. It offers 25mm of setback, and it comes with all the hardware to fit Monolink saddles or traditional saddles with round or ovalized rails. It has graduated markings on the back of the post at every 0. 5cm to help you dial in your fit.

Stylus 0 Ltd Seatpost 31.6, 280mm

Forward and aft positioning on the bike plays a large role in how much power a rider generates. Although a more relaxed (slacker) position is more comfortable, if you want to generate maximum speed without the discomfort of sitting on the nose of the saddle, try a forward position using the 3T Stylus LTD 0 Seatpost. This post is reminiscent of a traditional 2-bolt seatpost with a neutral -- 0 degree -- setback, clean lines, and weight-minimizing carbon construction. Unlike the 2-bolt seatposts of yore, this post utilizes bolts set on either side of the cradle, which allows for easier micro adjustments and extra stability. Both the shaft and saddle clamp are monocoque high-modulus carbon fiber and the bolts are steel, making this the lightest seatpost in the Stylus line. The Stylus 0 places the seat clamp assembly directly in line with the seatpost shaft. This 0 degree of setback is optimal when your frame design has a slacker seat tube: it is lighter in weight as compared to a setback post and shifts your position forward to compensate for your frame design. The 0 degree setback is also ideal if you want a more forward TT position on your already aggressive bike frame to maximize power. The 3T Stylus LTD 0 Seatpost is available in 27. 2mm or 31. 6mm diameters and 280mm, 350mm or 420mm lengths. The post is available in Gloss Black and weighs roughly 140g (31. 6mm x 280mm).

Haven Carbon Seatpost

Easton's Haven Zero Setback Carbon Seatpost is only 50 grams heavier than the brand's ultra-XC-focused EC90 Carbon Seatpost, even though the Haven is built be to mounted on long-travel, all-mountain rigs that will see far more shuttle runs than leg-searing uphill churns. If it's a head scratcher how a carbon post is fit for all-mountain fun, the secret is in the sauce. Said ingredients include not only using carbon, but knowing where to take it away. That is, Easton uses Relief Area Design, RAD for short, that pares some of the material on the back of the seatpost, leaving a lengthwise flat strip. This is where most seatpost clamps over-stress the post, especially if you apply too much force to the clamp. By flattening the rear of the post, the pinch force of the clamp is redistributed around the entire shaft, relieving any potential over-stress. Easton also builds the Haven Zero Setback Carbon Seatpost with a TaperWall layup schedule. This determines that the shaft of the post that sits inside the seat tube is reinforced, but the exposed length is lightened to reduce weight. Of course, the seat clamp zone is also bolstered so it can handle all of the levering forces from the saddle. Additionally, TaperWall is a computer-designed system -- both the layup schedule and actual application are precisely controlled so that all plies are completely smooth and void-free. Voids and peaks and valleys in a layup create their own stress points that interrupt load forces and can later result in failures. And if all that sounds like mumbo jumbo, know that Easton backs this post with a five-year warranty. That's not mumbo jumbo at all. That's confidence. The Easton Haven Zero Setback Carbon Seatpost is 400mm in length, and is available in the sizes 27. 2, 30. 9, and 31. 6, and in the color Matte Carbon.

CR4 Carbon Road Bike - 11 Speed Ultegra Save on Fuji GT and Nashbar Road Bikes

Nashbar CR4 Carbon Road Bike - 11 Speed Ultegra. Every time Nashbar introduces a new carbon road bike, it gets more tricked out, more weight weenie-ish, more race-ready, and more drool worthy--well, this time we're just getting plain ridiculous. The new Nashbar CR4 Carbon Road Bike has no Achilles heel, no boat anchor parts, just bliss from the bar tape to the tires. The CR4 Carbon Monocoque frame is this-season's best industry technology with a tapered head tube and full carbon fork to make the setup so responsive to your pedal stroke that you'll be inspired from the start. And speaking of pedal strokes, not one iota of your strength will go to waste with an oversize BB-30 bottom bracket anchoring the frameset. Not only is weight saved by eliminating the cups, but the stiffness is quite simply sublime. With so much more surface area up for grabs to attach the down tube, seat tube and chainstays -- plus room for a stout 30mm bottom bracket spindle -- deflection from all those watts you're producing is just not a worry. But don't let all this talk about stiffness worry you about comfort, because the wonders of carbon are evident in the stays which are shaped to further reduce road vibration. With so much awesomeness going on with the frame, this featherweight filly deserves -- and most assuredly receives -- a component package to match. Gram for gram, dollar for dollar, you'd be hard-pressed to find a finer choice than Shimano Ultegra 6800 11-speed and we've spec'd plenty of it: shift/brake levers, crankset, front derailleur, rear derailleur, and cassette. The shifting is just perfect while the compact 50/34T crankset ensures you can both tame any climb as well as contest rip roaring county line sprints. You'll be blown away by how well this stuff works as so much functionality, precision, and reliability has trickled down from big brother Dura-Ace that Ultegra is a tour de force in its own right. Look closely at the pro peloton and you'll see ballers on budgets winning big-time races on Ultegra 11-speed equipped rigs. Shimano also cranks out remarkable wheels and the RS11s are a paragon of versatility. Their 24mm-deep aluminum rims strike a balance between aerodynamics and handling while stainless steel bladed spokes, 16 front and 20 rear, will slice through the wind with aplomb. But these hoops aren't just for race day as they're sturdy and reliable enough to put through the paces day-in and day-out. There's no skimping regarding rubber, too, as folding Hutchinson Equinox 2 tires are a true all-around, all-weather performer with dual compound treads and a compliant, resilient casing. It's only appropriate that a bike begging to be pushed to the limits has a plethora of Full Speed Ahead parts throughout. The renowned manufacture of high-end aluminum goodness is the perfect choice for the handlebars, stem, brakes, bottom bracket, and seatpost. FSA's Omega compact bars are ergonomic wonders that are double butted for strength while the cold forged

SL Speed Seatpost Carbon, 20/330mm/27.2

If there's one thing that Zipp excels at, it's taking a good idea and rolling with it. Take Firecrest for example. In a matter of a few years, it's extended itself to every iteration of Zipp carbon wheels -- and for good reason, too. The same principle applies, here, with the SL Speed Seatpost. With an overall weight that's 35 grams lighter than the Service Course Seatpost, the top-of-the-line SL Speed shares the same highly-adjustable and low-profile clamp system as the Service Course, only opting for a carbon fiber construction instead of aluminum. This means that the Speed SL's not only lighter, but it'll also provide enhanced ride characteristics. Zipp's carbon mastery allowed it to chisel the Speed SL's weight securely under 190g. Impressively, though, this reduction was also coupled with an enhancement to strength, resulting in a post durable enough for use in races, like Roubaix, that explore component limits. In fact, the Speed SL's strength warrants a 300lb rider weight limit -- the same as Zipp's alloy posts. Also shared with those posts, as mentioned above, is the clamping system. Zipp's theory on saddle position is to provide as much adjustment as possible. And by paying close attention to the clamp assembly, Zipp's engineers have designed a two-bolt system with both extended range and angle adjustment. This allows you to find a position that permits the most power and comfort, and once adjusted, the titanium, two-bolt assembly is ensured to not slip out of place. The lower portion of the clamp is designed to be a bit longer than what you see on other seatposts. Essentially, this is to support the saddle rails for those of you who prefer a rearward position. And in this day of ultralight titanium and carbon rails, the extra support and insurance against rail damage is a definite improvement. The Zipp SL Speed Seatpost is available in a 330 length and in both 27. 2 and 31. 6mm diameters. Additionally, each length and diameter option is available in...

RDO Carbon Seatpost

It will only take one ride on a Niner RDO Carbon Seatpost for you to feel the difference. Whether your ride a hardtail or a full-suspension bike, you'll notice less fatigue at the end of that ride thanks to what Niner calls the 'unstiff' carbon layup. Niner states that its monocoque design deflects up to twice as much as other leading carbon posts; in fact, it'll deflect 8. 2mm under a 50kg load. For comparison's sake, Niner's standard-issue carbon posts deflects 6. 3mm under the same load. Unlike other posts that use bonding to join disparate materials, the RDO (Race Day Optimized) post is molded into a single, structurally superior shaft. Niner varies wall thickness and the carbon weave to offer the strength needed, but tunes it to flex so as to allow the post to dampen fatiguing buzz. A simple-to-adjust, two-bolt clamp ensures you'll quickly dial in the perfect saddle position, and it features an alloy head for durability. The Niner RDO Carbon Seatpost is a zero-offset post and comes in 27. 2, 30. 9, and 31. 6mm diameters. The 30. 9 post is 370mm long, while the 27. 2 and 31. 6 posts are 400mm.
