Nukeproof external bottom bracket


NUKEPROOF'S CARTRIDGE BEARING bottom bracket fits all standard 68mm and 73mm shell frames (there's an 83mm version too) and can be installed using a conventional BB tool.

It has CNC machined cups, a central alloy sleeve and comes with stainless steel bearings as standard, with a ceramic option too.

Disappointingly, the non-driveside bearing seized on us after just under four months' use. It's been an exceptionally wet winter and the BB I should last longer if you ensure there's plenty of grease around the bearings and use a water displacing lube after wet rides. But we've had other BBs outlast this one by years.

PRICE: 45$

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'.

Scott Scale 950

The Scale 950 uses the now traditional-for-cross-country 29er wheels to excellent effect, with a fast but fun character that's happy racing or railing.

Merida Big Seven 100

We've rolled up to our local woods, with a meandering blue trail, some natural wooded tracks and a bit of fire road chucked into the mix to see how the Big Seven 100 tackles trails that entry-level riders are likely to cut their teeth on.

COMMENCAL EL CAMINO 3

Commencal are going from strength to strength at the moment and they’ve taken their tough trail hardtail bang up to date with 650b wheels. With its skinny rims, crankset and fork, the El Camino certainly isn’t perfect and it’s the least hardcore bike here. The handling, smoothness, speed and all-round agility of the basic bike still make it a real blast for technical trail riding though, and it’s a great base for upgrading over time.

CUBE REACTION GTC PRO 27.5

Cube have kept their strong 29er race hardtail range for 2014 but added four new bikes with 650b wheels. The Reaction GTC Pro 27.5 is the second-tier carbon model.
