Specialized's 2011 mountain bikes: Epic, Camber and more

New trail bike, 29ers and updates to existing models

Specialized have launched their 2011 mountain bike line in Keystone, Colorado, with an all-new Camber 120mm-travel trail bike, redesigned Epic, updated Safire women's model plus 29ers and a new Evo line.

The most groundbreaking of the new bikes is the Epic. While it closely resembles the 2010 bike, the 2011 incarnation is all-new. The front end of the carbon fibre frame has been reworked with a new top tube that drops last year's top tube/seat tube strut in favour of a heavily-flared aft section. This is not only lighter, but also simplifies production.

Specialized have also moved to a Pressfit 30 bottom bracket, citing reduced weight and compatibility with any cranks via adaptors. At the back, the top-flight S-Works model is unique among cross-country bikes, featuring as it does a 142x12mm through-axle. Wheel guides on the inner faces of the dropouts make for quick changes, while Specialized have come up with special Roval wheels to work with the system.

They've maximised the flange spacing on the rear hub by taking advantage of the extra width to move the cassette slightly outboard, making for a stiffer wheel. The new dropout/wheel system is called 142+ to distinguish it from conventional (although as yet rarely seen) 142mm back ends.

Part of the motivation for stiffening the frame and wheels was to improve the ride of 29in-wheeled bikes, of which Specialized have many in their 2011 range. In the 26in Epic range, only the S-Works has the 142+ rear end (although you'll now find carbon frames down to Comp level), while it's found across the range in the 29ers.

Specialized are making a big thing about the S-Works Epic 29, which is understandable given that it's the lightest full-suspension 29er yet built at 9.66kg (21.27lb). That's helped by the new Roval Control SL 29 wheelset, which uses carbon fibre rims to drop weight to 1,400g.

Oversized end caps at the front and wide-stance spoke flanges boost stiffness, with the 142+ rear wheel is claimed to be 20 percent stiffer than the previous top-end Roval 29er wheels. All this tech finds its way into the Control SL 26in wheels too, with a weight of 1,200g and even more startling stiffness gains.

While the Specialized/Fox Mini Brain inertia valve shock is still present at the rear, and Specialized's own E100 fork still graces the front of the high-end 26in bikes, the 29ers and lowlier 26ers get a new RockShox Reba S29 fork that includes a Brain valve. This is the first time Specialized have carried out this kind of development with a suspension manufacturer other than Fox Racing Shox.

You'll also find double-ring chainsets across the Epic ranges, a feature that's prominent in the 2011 Specialized range as a whole. With 10-speed cassettes available across the board from SRAM and Shimano for 2010, Specialized have taken the decision to use doubles wherever they can, tuning the choice of rings to suit the intended use of the bikes.

You'll find 24/38T doubles across the Stumpjumper FSR and Enduro ranges, for example. Those bikes see few fundamental changes. The Specialized S140 fork on high-end Stumpjumpers has retuned, although it now won't feature a Brain inertia valve. The Enduro's E160 fork has been fiddled with internally, while the 160mm-travel all-mountain bike gets a new custom Fox RP23 shock.

Rather than a choice of settings with ProPedal platform damping on, the shock has a fixed 'lots of pedalling' setting and a choice of three levels of compression damping with the lever in the off position. Super-plush rear suspension is a wonderful thing, but many riders favour something a little pingier – if you like to jump, a back end that doesn't swallow lips and launchpads is a boon.

Specialized's new Camber 120mm-travel trail bike

The Stumpjumper FSR's move to 140mm travel in 2010 left a considerable gap between it and the 100mm Epic. For 2011 that gap's been filled by the all-new Camber. It's a 120mm-travel trail bike (or 100mm in its 29in incarnation) that will occupy a range of price points starting below the Stumpjumper FSR range but overlapping with it – the top-end Camber will be more expensive than the entry-level Stumpjumper.

The Camber is similar to the Stumpjumper in terms of geometry, but in a shorter-travel package. The all-aluminium frame uses integrated hydroforming, with the pivot locations being formed with the tubes rather than being separate welded-in forged sections. You also won't find any Brain shocks – Camber is all about simplicity. The top-end Pro models feature a custom SRAM carbon double crank, with triples on the cheaper bikes.

Big-wheel fans will also be interested in the new Stumpjumper 29er hardtails. With race wins at Sea Otter and TransGermany, and a World Cup podium spot, these may be the 29ers to convert an often-sceptical audience. They boast short chainstays and wheelbases and, importantly, low weight – the carbon 29in frame comes in at 1,049g.

That frame features hollow dropouts, a Pressfit 30 bottom bracket and takes a 27.2mm seatpost for extra comfort. All these features are also found on the 26in Stumpjumper HT frame, with a claimed weight of 920g.

Specialized have had an extensive women's range for several years, and there are several developments for 2011. First, there's an all-new Safire full-suspension bike. To improve performance, the Safire has moved to the shock position found on the Epic and Stumpjumper FSR, with the shock oriented in line with the seatstays.

That presented a conflict with a desire for lower standover height, but one that was neatly solved by mounting the shock in a forged pocket midway along the top tube. By tucking the shock up inside the top tube, standover height is claimed to be the lowest of any 120mm bike. The revised rear suspension is optimised for the lower shock pressures used by typically lighter women riders, with different rate curves compared to Specialized's men's bikes.

The Safire's cunning top tube construction is also found on the 100mm-travel Myka FSR. Specialized's ever-expanding 29er range extends to women's bikes too, with a 29er Myka hardtail that, impressively, comes in a range of sizes to fit riders from just 5ft tall.

Having already appeared at World Cup races (and in various photos and videos on the internet), the 2011 Demo downhill bike will already be known to many. Geometry is carried over from the previous bike, but the new Demo is lower-slung, with a shorter head tube and lower centre of gravity.

While the rear dropouts take a wide 150x12mm rear axle, the chainstays and seatstays are narrower for improved heel clearance, with wide, flat-pedal-friendly shoes. At 3in, shock stroke is slightly up on 2010 with a lower leverage ratio. The whole frame is also smoothed out, with potential mud-collecting pockets eliminated. There'll be no Demo 7 for 2011 – it'll be replaced by a new 180mm-travel SX Trail.

Specialized's final clutch of new bikes is the Evo line. These are pumped-up versions of other bikes in the range – there's an Enduro Evo with a Fox DHX coil shock; a Stumpjumper FSR Evo with 150mm travel front and rear, a chain guide, wider bars and bigger tyres; and even an Epic Evo with a 120mm fork. As if that wasn't enough, there are less-is-more race-oriented Evo R variants of the Epic and Stumpjumper HT, with 1x10 drivetrains and custom chainguides.
