The precision Swiss engineers are at it again with the BMC Crossmachine CXA01.

‘From as far back as 2007 and as recently as the beginning of ACE Technology [BMC’s computer designed frame programme] we’ve really been prioritising tube shapes,’ says BMC’s product marketing manager, Thomas McDaniel. ‘Of course round tube shapes are generally the easiest to produce, but we find that they don’t ride very well. So the Crossmachine has some seriously different tube shapes going on, and it’s definitely the most engineered alloy frame I’ve ever ridden.’

‘Thin seatstays add to a really accommodating rear end – you can actually lean on the seatpost and see how much movement there is. The “Crosslock” [the small gusset between the top of the seat tube and top tube] is there to offset the extra stress on the seat tube from having lowered the point where the seatstays join it, and the overall boxier profile tube shapes are designed to transmit pedalling power while being tuned for compliance to make the Crossmachine comfortable. Its geometry is a little taller at the front end and it has a longer wheelbase, resulting in an all-rounder bike. It’s not a full-throttle cross race bike, but rather one that’s perfect for enthusiastic riders who occasionally pin on a number.’

This all-rounder approach is reflected in BMC’s component choice. The Crossmachine CXA01 isn’t skimping with its use of Shimano’s top-end hydraulic R785 disc brakes controlled by the mechanical shifting RS685 levers. But it does combine them with the mid-level workhorse Shimano 105 drivetrain, albeit with the exception of the 105 chainset – here replaced with the more affordable, non-series Shimano RS500 to help keep the price-point competitive.

The frame can take up to 33c tyres, but McDaniel is keen to point out that a skinny set of rubber can transform the bike into a keen road racing machine, and then some: ‘The Crossmachine has rack and mudguard mounts, which together with wide clearances means it’s just as happy on a gravel adventure ride as it is touring, winter training in the rain or hacking through muddy fields. Such is the versatility, the Crossmachine could be a rider’s only bike. It will reset how you think an alloy bike will ride like.’
