Vittoria Martello rTNT DH 27.5x2.5in tyre


Vittoria’s reinforced Martello is monster heavy but has a surprisingly supple feel, good all-round grip, reasonable speed and excellent wear life. It’s a solid choice for heavy-duty bike park or e-bike use. At 1,460g, the ‘rTNT’ version with its beefed-up sidewalls is 500g heavier than the standard ‘TNT’ tyre in the 2.4in width. While nominally a 2.5in, it squares out to 61-64mm wide (2.4-2.5in), depending on rim width (30-35mm, internal). The fit feels baggy but is stable and secure down to mid-teen pressures. Unlike a lot of DH tyres, it doesn’t feel wooden or clunky in sub-warp-speed situations. In fact, it sucks up roots and rocks smoothly even on slow techy climbs, making it great for e-bike use, where weight isn’t an issue. The quadcompound rubber mix and squared and siped tread are generally predictable whether it’s wet or dry, loose or hard, and the tyre still rolls OK. Pricing is reasonable considering the level of technology and the grapheneboosted wear life of the tyre.

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'.

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...
