The Primo range from up and coming UK brand Mekk showcases its racing line-up, consisting of three models all built around the same frameset; the 6.0 is the most basic offering.
Frame and fork is constructed from 3K carbon-fibre, offering a good ratio of stiffness and strength. It has aero profiling, with the main triangle and fork all having optimally shaped tubes. The overall finish of the carbon, internal cable routing, graphics and decals all combine to make a sensibly good looking bike.
Mekk has not scrimped when ?it comes to components – there are no brands here that you haven’t heard of; Shimano, Ritchey, Mavic, Prologo, it’s all good stuff, even down to the ?race quality Michelin tyres.
The groupset consists of a full complement of 105 (likewise the next two models get full Ultegra and Ultegra Di2). While 105 may not have the kudos of its more expensive brothers, it is still good enough to race on and should give years of trouble-free service.
The wheels are Mavic Aksiums, although a very good wheelset it’s a bit of a disappointment to see them on here as they’re not renowned as race hoops, however like the rest of the components they are fully functional and ?work well.
Smooth and speedy
The first ride gave the impression of a well sorted bike. It’s comfortable and feels solidly built, and there’s a noticeably direct response to your power. The geometry is spot-on, making the riding experience feel nicely balanced; throw the bike around and the handling is reassuringly predictable. Where some race bikes are harsh and jittery the Primo is surefooted and the miles fly by.
The bike performs well once at speed on the flat, but as soon as the road heads uphill or you want to really kick out of a corner you’re reminded of the heavy Aksiums. The Michelin Pro4 tyres help to offset the rotating mass of the wheels a little and offer more comfort and control, it’s just a shame they aren’t wrapped around lighter wheels.
Mekk knows this bike will perform better with a wheel upgrade. If you’ve already got a decent set then fine, but if you haven’t and you want to get the true potential of this frame that should be factored in.
Putting in a lighter set of Mavic Ksyrium Elite S hoops transformed the ride; acceleration and road feedback noticeably increased, as did the bike’s climbing characteristics.
