Shimano SLX M670 transmission

Shimano SLX M670 transmission

IF YOU'RE NOT bothered about weight, Shimano SLX is literally a super-solid, full feature gearset.

The angular rear mech looks great on aggro trail bikes and the thick, pressed steel inner parallelogram/ actuator arm creates a bombproof spine. There's a standard low-profile Shadow version but hardcore riders should pay 15$ more for the tension adjustable and on/off switchable chain-taming clutch of the Shadow + version included here. It's heavier than the XT mech though and the jockey wheels get lower quality bearings that are slightly less durable.

Lever throw before each shift is also noticeably longer than with XT, which means a maximum downshift of three rather than four gears per stroke. Individual shifts aren't as crisp and positive when new either, though it still stays functional in filth for significantly longer than SRAM's 2x10 gear.

The PTFE coated, asymmetric plate HG75 chain is a great blend of performance and price, and the HG81 cassette mounts the largest three sprockets on an alloy carrier to save 66g over the solid Deore block. It's still worth trading up to XT if overall bike weight or high mileage is a concern though, and Zee would be our choice if we were planning to build up a hardcore 1x10 bike.

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'.

Pinnacle Ramin

Bikes in the 750$ to 1500$ range have never been so good. However, on many of these bikes a suspension fork from one of the major manufacturers is too expensive, and the cheaper alternatives don't quite pull their weight. They tend to be poorly sealed and before long become almost rigid, hefty lumps of metal attached to your frame.

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.

Canyon Spectral AL 6.0

Round two, and the 6.0 leaps out of the blocks. From the moment we're off the smaller wheeled Spectral wants to go flat out. Standing on the pedals on the small steep climbs is slightly more reactive, surging the Spectral forward that little more eagerly. We need more body language to get the wheels over the roots, but again the 2.4in Mountain King's tread impresses.

Canyon Spectral AL 7.9

Canyon's Spectral falls right in prime trail bike territory. The 29in Spectral AL 7.9 has 130mm of travel at both ends, coupled with the big wheels - ideal for covering distance at a fast pace.
