Shimano Deore XT M780 transmission

Shimano Deore XT M780 transmission

XT M780 IS now Shimano's oldest serving MTB gearset but it's still delivering shifting in a light, smooth and ultra durable format.

The rear mech comes in the regular Shadow version seen here or in Shadow Plus format with a chain-taming clutch for an extra tenner. Either way, the 3D formed SGS parallelograms give excellent stiffness and durability. The cartridge bearing jockey wheels last for ages too and the alloy cages can often be bent back after being mangled (unlike composite ones) yet the mech is still almost 50g lighter than the SLX equivalent.

The slick shifting 10-speed cassette carries most of the cogs on a lightweight alloy spider, saving 32g for only 12$, and the HG95 chain is a longevity benchmark. Shifting is sharper and faster than with SLX, with an extra gear (four, rather than three) per downshift too. Shifting can feel slightly indistinct compared to SRAM on rough trails but XT tolerates age and cable contamination much better.

The front trigger is dual directional, the shift indicator windows are removable and more kit is appearing that's compatible with Shimano's I-Spec combined clamps too. Shifters are available separately if you're planning on going 1x10.

WEIGHT 1,302g
FORMAT 2x10

PRICE 368$ (w/ Shadow mech)

KONA SHRED

With a reputation for no-nonsense ruggedness and a background in the always progressive and punishing riding of Canada, Kona have been building hardcore hardtails for longer than almost anyone else. The Shred is the most expensive bike on test but it’s a proper trail tank.

Cannondale Trail SL 29 SS

The fat aluminium tubes are a constrast to the skinny items seen elsewhere in the test, but this rigid Cannondale uses them to create one of the most old-school - and lightest - rides here.

ENVE M50 29" Wheels

Utah based company ENVE have been making drool-worthy carbon components for some years now. Despite the fact that carbon rims are becoming more and more common on mountain bikes these days, you can guarantee that ENVE wheels will be a talking point when someone is eyeing off a steed. Instantly, the big bold logos on each rim scream "fast", "light" and to some extent, "expensive" The kids call this 'bling'.

NS Bikes Metropolis bike

There aren’t many companies like NS Bikes, whose entire product range is designed around getting rad, ripping corners and boosting jumps. The Polish brand are passionate about freeride and have gained a reputation for building heavy-hitting,wellspecced and reasonably-priced bikes. This latest incarnation of their Metropolis dirt jump rig follows in this vein, with a doublebutted 4130 chromoly frame and an array of reliable kit. The frame mixes MTB and BMXtechnology, using a threaded bottom bracket and Race Face AEfect two-piece crankset in combination with horizontal dropouts and an integrated headset and seat clamp. A Manitou Circus Elite fork gives 100mm of air-sprung travel, with a 20mm front axle to maintain stifness. The Metropolis rolls on 26in NS Fundamental rims, fitted with Kenda Small Block 8 tyres. We reckon the combo of chrome frame and tan-wall rubber looks pretty rad too! The full build weighs a fairly robust 12.13kg , but it should have no problem shrugging of s...

YT Tues downhill bike

The new Tues downhill bike is here – and won a World Cup on its first outing While a number of big brands have launched 29er downhill bikes,YT Industries are sticking with proven 650b wheels – for now, at least. The latest Tues comes in five sizes (S-XXL), with the biggest sporting a reach of 495mm. Head tube and chainstay lengths now vary between sizes, to put the rider in a better position on the bike. The S-L bikes have 435mm stays, while the XL and XXL are a shade longer, at 440mm. Reach is longer than last year on some sizes, including the XL ridden to victory by Aaron Gwin at this year’s openingWorld Cup round.A reachadjust headset can be used to tailor the fit further. YT have also made subtle but significant changes to the suspension. The initial stroke is said to be more sensitive, while there’s more mid-stroke support, to sit the bottom bracket a shade higher when on track.YT have decreased end-stroke progression, by five per cent, to make tackling really big hits th...
