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.

Nukeproof Vector AM Comp Cro-Mo saddle

The Vector AM is pretty race focused, with minimal padding. There’s a deep (if narrow) pressurerelief channel to keep the blood flowing where it’s meant to. Used with bib shorts, we found it pretty comfortable for shorter rides and suffered no pain or discomfort in the central region. On steep climbs the slightly downturned nose provides a reasonable forward perch, while the svelte profile and smooth edges make it particularly unobtrusive when moving about on the descents. It’s quite stiff though, and can feel harsh on long rides or bumpy ground. We definitely wouldn’t want to spend much time on it without a chamois. It’s heavier than we’d expect for such a lightly padded perch too. There’s a lighter Pro version with titanium rails for $105, but at 241g it’s only 10g lighter. Weight 251g Price $67

GT Zaskar Evolution

While some bike models last just a couple of years, others change with the times to stay at the top of riders’ wishlists. In the second part of this series looking at the evolution of bikes that enjoy enduring popularity with UK riders, we turn to the GT Zaskar – a bike that was at the forefront of our sport for a long time and still has plenty of appeal today.

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.

CANYON NERVE AL 8.0

  S ince their entry into the UK market a few years ago, Canyon have made a name for themselves as purveyors of well-made bikes that exhibit often extraordinary value. The secret (or catch, depending on your point of view) is that the brand don’t have dealers – they ship bikes directly to your door.
