First Impressions: Cirrus Cycles BodyFloat Seatpost

While most recreational cyclists will never compete, racing drives a significant percentage of the bicycle industry’s product development and marketing. Terms like lighter, stiffer, and faster are all used to describe the latest and greatest products. But what about comfort? Are comfort and performance mutually exclusive? Not according to Cirrus Cycles. The company’s BodyFloat™ seatpost is designed to improve comfort and performance by isolating the rider from high-frequency vibrations.

Unlike telescoping suspension seatposts, the BodyFloat post uses a linkage system that produces a vertical motion–which, according to the company–does a better job of isolating the rider (aka, the bike’s motor) from vibration. That motion, combined with the system’s undamped coil springs, results in a quicker response, which is purportedly critical for quelling high-frequency vibrations. To accommodate different sized riders, Cirrus offers four spring rates in two sizes (1.5-inch for the top position, and 1.75-inch for the lower position). When you order a BodyFloat seatpost, you specify your weight, the type of bicycle (road, mountain, etc), and handlebar style (drop or flat). For review purposes, my sample seatposts included all four spring rates, so I was able to experiment with various combinations.

The twin springs are easily changed to accommodate cyclists ranging from 50 to 260 pounds.

As I’m very particular about my saddle height, I was initially concerned that replicating my preferred position would be difficult due to the BodyFloat’s vertical movement. To be completely honest, however, once I found the correct spring rate combination (orange/orange), dialing in my fit was no more difficult than swapping saddles or seatposts. One or two short rides spent tweaking saddle height were all that it took to find the sweet spot. Fine-tuning the saddle height and spring tension was easy thanks to the post’s pre-load bolt. And because the Cirrus post doesn’t rely on rearward travel, I was able to directly transfer my saddle’s fore/aft position to the BodyFloat seatpost.

Hopping aboard the BodyFloat-equipped bike for the first time immediately reminded of me of my old Softride beam bike. That shouldn’t come as a surprise, as Cirrus’ founders and engineers were involved with the original Alsop Softride beam design. And as I would do with that beam bike, the first thing I did was check the tire pressure to see if it was too low. Like a big, soft tire, the BodyFloat seatpost’s smooth ride is immediately apparent. Unlike those beam bikes, though, there’s no lateral sway with the Cirrus post. And once you’ve selected the correct spring rates, there’s no bouncing or bobbing with the BodyFloat post.

When I began testing Cirrus’ seatpost, I discovered that I had a tendency to hover slightly above the saddle when traversing broken pavement or bumpy trails. My legs and upper body would stiffen, causing me to expend additional energy so that I could isolate myself from road buzz and chatter. As I logged more miles on the BodyFloat, that tendency to brace myself subsided. After a couple of weeks, I was taking full advantage of the BodyFloat’s isolation capabilities. On a whim, I swapped out the Cirrus post with my bike’s original rigid seatpost. Using the same saddle and tires, the difference in comfort was like night and day. Broken pavement and washboard trails that went unnoticed aboard the BodyFloat post now felt like rock gardens by comparison.

Does the BodyFloat work as advertised? Absolutely. It’s does an outstanding job of isolating the rider (aka, the engine/motor) from road shock and vibrations. With the BodyFloat, your entire body feels more relaxed. That relaxation translates to increased efficiency–and enjoyment–because you’re not wasting energy by tensing up to brace against bumps and cracks. After four months of use, I’m completely sold on the product, and can’t see myself going back to traditional seatposts on my un-suspended bicycles.

With a price of $249 for the alloy model ($395 and $415 for the carbon and titanium models, respectively), some folks will undoubtedly balk at the BodyFloat’s cost. While not exactly cheap, you could easily burn through that much money trying to find a more comfortable saddle (or worse, an entirely new bicycle). And speaking of saddles… I tested the Cirrus post with a dozen different saddles, and models that were so-so on rigid posts felt much more comfortable when paired with the BodyFloat.

One-Year Review: Specialized AWOL Comp Bicycle

Adventure often means different things to different people, and Specialized’s family of adventure bikes is as diverse as the word itself. Designed to combine versatility and durability, the company’s AWOL line has become extremely popular since its introduction in 2014. Over the past twelve months, Specialized’s AWOL Comp has seen regular duty as my daily commuter, dirt-road and gravel rig, and primary test bed for numerous components and accessories.

At the heart of the matte black Comp is its TIG-welded frame and fork. The frame is constructed from a blend of Reynolds 725 and 520 steel tubing, and a CroMo unicrown fork completes the package. For maximum versatility, Specialized chose custom rocker-style dropouts, making the AWOL compatible with internally geared hubs, single speed setups, and belt drive systems. There’s no shortage of braze-on fittings, either–the bike has mounts for three bottle cages, front and rear racks, fenders, and all the necessary cable guides and stops for a 1x, 2x, or 3x drivetrain.

The AWOL Comp outfitted with front and rear Tubus racks and Ortlieb panniers.

While many of my own personal bikes have what’s known as square geometry (seat tube length = top tube length), the Comp has a much longer front end. The medium size that I tested featured a 57.5 cm effective top tube, and a stack and reach of 61.7 cm and 39.2 cm, respectively. For comparison, my 56 cm Salsa Vaya has a stack height of 61.9 cm, a reach of 37.1 cm, and a 56 cm effective top tube. To compensate for the very long top tube, Specialized spec’d the medium AWOL Comp with a shorter-than-average 75 mm stem. Wheelbase on the Comp measured a lengthy 107.2 cm.

On my first shakedown ride, the AWOL immediately felt stable and predictable. Getting used to a new bike usually takes a few rides (and fine tuning), but the Comp’s ride was familiar and reassuring. Transitioning between paved and unpaved surfaces was completely uneventful, and riding no-handed didn’t require extra concentration or gymnastics. The combination of the AWOL’s relaxed steel frame, wide (700×42) tires, and gel handlebar padding yielded a Cadillac-like ride that soaked up road buzz and trail chatter like no other bike I’ve ridden in recent years.

Much of the AWOL’s testing centered around my 12-mile commute. The route includes a mix of paved and unpaved roads and trails, and I routinely carry 8-10 pounds of cargo. Experimenting with front and rear racks from Blackburn, Surly, and Tubus, I found that low-riders and small panniers worked best. Whether it was due to the Comp’s long front-center, or slender seat stays, heavy rear loads produced noticeable sway. The worst offender was a large Carradice saddlebag, but even small panniers attached to sturdy steel (rear) racks affected the bike’s handling.

Because of the AWOL’s weight (30 pounds, stock) and relaxed geometry, it may not the best choice for fast, unloaded riding. I found that, even when outfitted with lightweight carbon wheels, my commute took approximately 10-15% longer aboard the Comp. Speed isn’t everything, though. If enjoying the scenery is more appealing than bagging a Strava KOM, then the AWOL will keep you happily rolling along while you take in the sights and scenery.

Specialized’s component choices for the AWOL definitely favor reliability. The Comp’s parts may not be the lightest or have the highest pedigree, but they’re solid performers with proven track records. The Avid mechanical BB7 disc brakes don’t require bleeding like hydraulic units, and SRAM’s X9 rear derailleur features a roller clutch to help reduce chain-slap. Full-length cable housing and liners keep the controls operating smoothly. Specialized’s house-brand components, however, were a mixed bag. The flared drop bars offered excellent control, and the stem’s eccentric shim enabled additional adjustment compared to standard units. Accessing the front bolt on the seatpost was difficult if you weren’t using a saddle with a cut-out. And speaking of saddles, the stock perch was immediately replaced with one more befitting the bike’s relaxed nature.

Thanks to the frame and fork’s ample clearances, a change of tires is all that’s needed for serious dirt and gravel exploration. The stock 700×42 Trigger Sport tires may be fine for mellow hardpack, but the AWOL can easily accommodate bigger, more aggressive rubber. Throw on a pair of Specialized’s 29×1.9 Ground Control knobbies and you’re ready for anything short of technical, rocky singletrack. I rode that same setup (albeit tubeless) at SRAM’s Road 1x product launch, and the Comp was a blast on the long, unpaved descents near San Luis Obispo.

For 2016, Specialized now offers four complete AWOLs that range in price from $1350 to $2500. For the DIY’ers, there’s also the $700 AWOL Expert frameset. The biggest changes to this year’s Comp are the switch to SRAM Force hydraulic brakes (a welcome upgrade, in my opinion) and the move to a 1×11 drivetrain. If a single-chainring setup isn’t your thing, Specialized offers two models with doubles, and the base AWOL comes equipped with an FSA 50/39/30 triple crankset. Riders looking for the ultimate commuter-slash-adventure rig should check out the $2500 AWOL EVO, which includes a dynamo hub to power its Supernova lights and USB charging port.
