Cannondale Scalpel 29'er Carbon 2 review
Many 100mm travel 29ers can happily serve double-duty as trail bikes, but the Cannondale Scalpel 29'er Carbon 2 is a more finely specialized beast, with a firmer feel and quicker reflexes.
What it might lack in plushness it more than makes up for in speed, though, making it a superb rig for racing or just covering cross-country trails in a hurry.
Ride & handling: Incredibly efficient and fast
Cannondale has certainly chosen an apt moniker for the Scalpel 29'er Carbon 2 – imagine a mountain bike translation of that razor-sharp surgical instrument and that's pretty much what you get. And riding it with a deft hand pays more dividends than a more brutal approach: choose a line, slice and dice, and cut your way through your chosen singletrack path with minimal resistance and lots of speed.
One key to the Cannondale's immensely precise feel is its remarkably stout carbon chassis, which is extraordinarily stiff in terms of both full-frame torsion and drivetrain efficiency. Add in the always surprisingly stiff Lefty fork and you get a fantastic level of responsiveness to steering inputs, even in high-load corners that might otherwise cause a flexier chassis to load up and unpredictably spring out at the exit.
Some riders might find the stock 71-degree head tube angle to be a bit on the steep side, however. When mixed with the stiff frame and relatively short 444mm chain stays it yields very quick reflexes. Thankfully, though, buyers can swap the short aluminum head tube extension from top to bottom to kick the angles back a hair (which we did happily).
Under power, the Scalpel is flat-out glorious, especially uphill. Cannondale has placed the main pivot just above the inner chainring, which combines with the impressively flex-free rear end to help subtly dig the rear wheel into the ground when you stomp on the pedals.
Switching to the big ring yields a touch more movement under hard pedaling but even then it's virtually unnoticeable. In fact, the Scalpel's rear end is so efficient that we almost never needed to engage even the platform setting on the RockShox Monarch RT3 rear shock, let alone the full lockout.
That being said, some of that incredible efficiency comes as a result of relatively firmly damped suspension components front and rear. Both ends undoubtedly work well – we were able to get full travel and enjoyed the traction and fatigue benefits of full suspension – but the Scalpel still feels more firm than plush. With the added spring rate of the springy seat stays, the rear end also sometimes feels as though it has less travel than it does.
We also wished for revised valving up front, as the Lefty XLR fork's high-speed circuitry doesn't seem as accommodating of especially harsh, square-edge impacts as the RockShox Monarch RT3 rear shock, despite the silky smooth needle bearing guts. In addition, the rebound damping could be a little quicker in some situations.
Cannondale's Lefty fork still draws stares for its unique single-sided design
Idiosyncrasies surrounding Cannondale's proprietary Lefty front end also yield some quirks in rider positioning. Head tube lengths are identical across the size range and measure a comparatively long 135mm from end to end – a whopping 45mm longer than some of the shortest conventional head tubes currently used on modern 29ers.
As a result, we could barely achieve parity between the saddle and handlebar heights even with the stock -15-degree stem. It's worth noting that smaller riders would have an even harder time. Cannondale offers the option of a standard steerer and clamp-on stem but that route foregoes some of the weight-saving benefits of the OPI integrated setup.
Frame & equipment: Wonderfully light and awesomely stiff with performance parts
That Cannondale was able to produce such a rock-solid chassis with an actual frame weight of just 2.12kg (4.67lb, medium, with shock, seatpost collar, derailleur hanger and requisite hardware) is testament to careful composite design. Case in point is the carbon rear triangle, which foregoes conventional dropout pivots in favor of flattened seat stays with tuned flex patterns to accommodate changes in geometry as the swingarm moves through its 100mm of travel.
As expected, the front triangle tube cross-sections are enormous – especially up around the head tube area. The same goes for the asymmetrical chain stays and the seat stays, which are flattened to accommodate changes in geometry as the rear end moves through its travel.
In addition, the seat tube is highly asymmetrical, the rear end is tied together with Syntace's bolt-on 142x12mm through-axle and the full-length housings are secured to the down tube with tidy aluminum clamps. Down below is Cannondale's familiar BB30 bottom bracket design but with press-fit cups.
It's the smaller details that strike us as more impressive, though. For example, rather than use conventional blind pivot axles that independently thread into a central shaft from the outside, Cannondale uses a through-axle setup at the main pivot and the bottom of the shock link. According to Cannondale, rigidly clamping things together in this fashion decreases twist under load – a goal that has seemingly been accomplished with aplomb here.
In addition, the shock link itself is a notably stout chunk of aluminum and the seat stays are further tied together with a bridge on the bolt-on cap.
Other subtle touches include a sandwich-style rear derailleur hanger for improved shift precision, flares around the upper shock link pivot to protect your legs from the protruding hardware, Pivot design, rear derailleur hanger, a flared seat tube to shield the linkage pivot and even a pivoting housing stop to maintain smooth cable paths to different brands of direct-mount front derailleurs.
Cannondale's flagship Scalpel 29'er Carbon 1 uses the same frame but a higher-end build to shave roughly a kilogram of weight – but at an extra cost of US$2,300. Weight weenies with deep pockets will obviously want to go down that route. Otherwise, though, the Scalpel 29'er Carbon 2 leaves little to be desired and is already quite light at 10.98kg (24.21lb) overall, without pedals.
The OPI stem is forged as a single piece with most of the steerer tube
Cannondale builds the second-tier Scalpel with a diverse mix of components: a carbon fiber 2x10 crankset, Elixir 9 disc brakes, an X9 front derailleur and PG 1070 cassette from SRAM. Plus Shimano's awesome XTR Shadow Plus rear derailleur with its built-in one-way friction clutch cage and Deore XT trigger shifters, a KMC chain and custom wheels built with Stan's NoTubes ZTR Crest tubeless rims, DT Swiss Competition butted spokes and Cannondale's own Lefty SL front and Sun-Ringlé Dirty Flea rear hubs.
Shift action front and rear was quick and positive (although with noticeably more lever effort on the rear due to the clutch). The brakes eventually settled in with firm levers, excellent power and quiet operation.
While a bit flexier than we'd like in particularly hard and tight corners, the Stan's wheels are impressively light and a breeze to set up tubeless with the included valve stems. They provide good casing support to the voluminous, fast-rolling and surprisingly grippy Schwalbe Racing Ralph tires.
Likewise, we have little to complain about with the cockpit components. The trick OPI one-piece forged aluminum stem and steerer tube is amply rigid and cleverly saves weight, the Truvativ Noir T30 flat carbon bar is usefully wide at 700mm across and the Fizik Cyrano aluminum seatpost is secure and easy to adjust.
The matching Tundra 2 saddle – while very firm – is nonetheless very comfortable even after long days on the trail. If we really have to nitpick, we'd argue that the stock lock-on grips offer a secure hold but too little padding.
True, certain substitutions could save a few grams – Shimano's standard XTR rear derailleur and a 160mm front rotor (instead of the 180mm one included), for example. But the stock bits are wisely chosen with good benefits to go along with the extra mass.
In fact, unless you're after the absolutely lightest in Cannondale's Scalpel 29'er range, we'd say there's no reason to spend any more – the Scalpel 29'er Carbon 2 is simply brilliant as is.

View Thumbnail GalleryAfter nearly four years of development, Orbea onSunday released the new Ordu time trial/triathlon bike in Denver. Besidessubstantial gains in aerodynamics over the old Ordu, the new Ordu frames offerhuge adjustability in fit. Also, one model comes with Shimano’s brand newelectric Ultegra Di2 time trial/triathlon wiring system.One unique feature of the frame is the integratedMonolink stem, which pivots at the steerer tube for 140 degrees of verticaladjustment. Further, each frame ships with four stem lengths (75, 95, 110 and120mm) to dial in handlebar position without a single spacer.
“It’s super clean,” said Orbea USA’s managingdirector Tony Karklins. “There are no spacers, no shims. You don’t have to useany specific handlebars. For a bike fitter, it’s a dream.”
The bike comes in four frame sizes, the smallestof which is a 650c bike. “We’re calling that one a 48cm frame, but it’s muchsmaller than a 700c 48cm bike,” Karklins said.
The bike comes in five models, including the$5,499 GLi2 with the new Shimano Ultegra Di2 time trial/triathlon drivetrain.“We expect this one to be huge,” Karklins said. “With the new Di2 wiring at thenew Ultegra price point, this is going to change the game. Now you can haveelectric time trial and triathlon bikes at a completely new price point.”
The other bikes include the $4.499 Ordu GLT withmechanical Ultegra, the $5,999 Ordu GRD with SRAM Red, the $6,499 Ordu GDR with11-speed Shimano Dura-Ace and, by spring, the GDi2 with 11-speed Dura-Ace Di2.
The integrated Monolink stems feature 140 degrees of vertical adjustment
While many companies have chosen to tuck thefront brake of their TT/tri bikes behind or inside the fork, Orbea stuck with astandard caliper. This move wasn’t out of laziness, however, but theirwind-tunnel work.
“We choose not to go internal on the brakecaliper on the fork, because as we were doing work to put the caliper inside,the fork kept getting less and less aerodynamic,” Karklins said. “Also, thereare lots of great aero calipers out there from Magura, Tetkro and others. Andat the same time, we know the disc brake train is coming for triathlon/TTbikes.”
Each Ordu ships with two tops caps for organizing internal cable routing: one for mechanical systems and one for electric drivetrains
Karklins said that although the bike made hugegains in aerodynamic drag over the previous Ordu, “we still took time to makesure the bike rides the way you want it to ride.”
“You can make some tubes a little too thin, and whileit may look fast, it can compromiseride quality,” Karklins said.
Matching the stem, the Ordu has a Monolinkseatpost, which comes with two kits: one for Monolink single-rail saddle andone for standard dual-rail saddles.
Also, the Ordu is selling with the popular ISMergonomic saddle for the first time.
The bikes will begin shipping in October.

"I got specified by John Morgan and the team atDisability Sports Wales to do that. I'd just like to thankfriends such a Magnus Backstedt and his family and my family and the manypeople who just turned up out of nowhere in the pouring rain for being part ofthe special day.”
The multi-Paralympic medalist's ownpreparations for London 2012 were dashed when he was knocked off his bike andleft for dead during an early morning training session just over a year ago by drunk and partially sighted farmer Edward Howell Adams, driving a van onthe A48 near Bridgend.
Talking about the court case which comes toa conclusion with sentencing for Adams this Thursday, he said: “It will be nice to getfull closure from the accident. Whatever happens, happens to him but the CPS haspushed hard so a precedent will hopefully be set so that drunk driving withadverse outcomes like this now automatically becomes dangerous driving.Hopefully my misfortune has helped the roads be slightly safer and to makeprocedure slightly easier for those involved in future incidents.”
“I would have loved tohave been there in London to compete but now I'm setting my goals on Rio," said a determined Richardson. "Ihave a really good team behind me and I'm looking forward to the (back)operation in mid-to-late September.” Whether he will be on a two wheeled bikeor in a hand-cycle remains to be seen as the procedure he will undergo willlikely reduce his ability to bend his spine.
