Pivot Mach 5.5 Carbon – Initial Impressions

This is the brand new Pivot Mach 5.5 Carbon – a 140mm travel frame, designed for 27.5in wheels and features clearance for up to 2.6in tyres.Pivot Mach 5.5 Carbon

This lovely looking frame features the DW Link suspension platform and has a new upper link with a cartridge bearing on the shock mount. This delivers an incredibly supple action – the friction normally felt on a traditional shock bush design is dramatically reduced by the use of a bearing.

The frame’s carbon structure is a new design too, and is almost as tough as the heavy-duty Firebird – but features a similar weight saving lay up to the lighter weight frames in the range. Pivot Mach 5.5 Carbon

Pivot Mach 5.5 Carbon

Pivot Cycles has used the DW-link system for years now, and is one of the best feeling platforms that uses the system. The back end is very active, but sits up in the travel more than some other twin linkage systems – this feels great on the trail, especially when climbing.

Whilst more and more bikes these days are designed with 1x transmissions in mind, Pivot Cycles still allow the use of a twin-chainring set up, using a removable e-type mount adaptor. There is full routing for Shimano Di2 integration, and also for the new Fox Live system that will be released soon.

The Pivot Mach 5.5 is a stunning looking bike, especially in the bold red colour – though a more subtle black model with blue detailing is available too. We know which we’d rather have…

How does it ride?

Whilst not quite in the realm of the really long bikes, the sizing on the Pivot Mach 5.5 is modern and has plenty of room – there’s also a load of stand over height. The head angle feels good at 66.5 degrees – aggressive enough for it’s intentions.

The back end is very supple – the combination of the cartridge bearing in the shock mount with the 2018 Fox EVOL shock just feels amazing. The wheel really does hug the contours of the ground, and the traction on offer is immense. This is further enhanced by the monstrously large 2.6 tyres, mounted on exclusive Reynolds carbon rims with a 36mm internal width.

The Pivot Mach 5.5 has a really playful ride – the 430mm chain stays encourage you to pop the front wheel up, and the bike is quite happy in the air too.

Although we didn’t spend long that long riding the Mach 5.5, we could tell that the frame is stiff – but not quite as stiff as the burlier Firebird. It’s definitely a bike that’s happy to be thrown down black rated trails, but is comfortable enough to be an all day trail cruiser too.
