New brand Mekk impressed
us with the £1,200 Poggio
. The Primo SI 5.5 comes in higher up the price
range, at the highly competitive £2,000 mark. At this level, value for money
still counts but it’s more important for a bike to have an impressive spec and

first glance the Mekk scores on both fronts, with a complete Shimano Ultegra
drivetrain – about as good as it gets as this price – and branded finishing kit
from the likes of Mavic and Ritchey. Designed in Italy
and manufactured in the Far East, the frameset
is bang up to date too, with aerodynamic lines.

front, a tapered head tube blends seamlessly into a deep-bladed aero fork. The
deep down tube and seat tube continue the wind-cheating theme, while an
oversize bottom bracket shell and deep chainstays boost stiffness for improved
power delivery. The frame is completed by a slim top tube and skinny seatstays.

Mekk has an aggressive ride position, achieved with a combination of a low front
end, longish top tube and long (120mm) stem. We like the clean lines and understated graphics, and
there are some neat frame features too, like a hidden seatpost clamp and
dedicated carbon aero post. Carbon dropouts add to the svelte look.

narrow aero tubing gives the bike a sharp-edged feel and it responds to rider
inputs with immediacy. This responsiveness is only tempered slightly by the
stout wheelset and heavy tyres.

wheels are well built, stiff and use Mavic’s legendarily hardy CXP 22 rims (on
unbranded hubs). They’d be fine for commuting or training but they’re a little
underwhelming on a frameset as accomplished as this. The same can be said for
the Continental tyres. The Ultra Sport is tough and has a decent tread but it
doesn’t roll as fast as we’d like.

Mekk’s ride isn’t the most cosseting and some road buzz makes its way through
to your hands, but this is easy to live with. It also isn’t as sharp through
the turns as the best of the competition, with a tendency to run wider from the
ideal line – something we put down to the low position and long stem. Overall,
though, it performed admirably on the climbs and rolling, twisty back roads of
our main test route.

it was when we took the SI 5.5 for a 60-mile ride around Spalding in Lincolnshire that it came
into its own. Tucking into an aero position and stomping on the pedals on the
flat, straight Fenland roads, the heavy wheel and tyre package ceased to be an
issue once up to speed. The frame’s slippery lines got on with beating the wind
and we were propelled along at a rapid pace. We can see a bright future for
Mekk if they continue producing bikes of this calibre.
