Bike of the Week | Wilier Cento10 SL

The Cento10 SL is the more affordable counterpart to Wilier’s flagship Cento10 Pro aero race bike.

With a frame that’s a claimed 200g heavier than the top-end bike and a more conventional cockpit setup, the Cento10 SL starts at £2,450 / €2,700 and costs £5,540 / €5,600 in the spec we have here, with Shimano Ultegra Di2 and Wilier’s own carbon clinchers.

Wilier Cento10 SL: racy, red and rim-optional

Although it’s the second-tier model, there’s nothing budget about this bike and the model we have here is sporting the most expensive build on offer.

The Cento10 SL’s frame weighs a claimed 1,190g for a medium, a penalty of 200g over the Pro flagship.

It’s available with rim brakes if you want them, but most riders will likely be opting for this disc version.

Outwardly, the SL and Pro are very, very similar, with truncated aerofoil tube profiles throughout.

A key difference is that the SL lacks the alloy plate set into the down tube, which houses the control box for electronic groupsets.

Perhaps as a consequence of this, Wilier claims the SL’s torsional frame stiffness is actually slightly higher than that of the Pro, although the brand doesn’t divulge numbers on this.

The SL also gets a more conventional cockpit setup, with a Ritchey-made bar and stem in place of the Pro’s Alabarda one-piece carbon cockpit.

Despite this, the cable routing is almost fully integrated, disappearing into the headset beneath the stem.

There’s been a definite trend towards bigger tyre clearances on race bikes and the Wilier officially accepts 30mm rubber in its disc incarnation.

In a more conservative vein, the Wilier carbon clinchers are just 17mm-wide internally – comparatively narrow by current standards.

This XL bike weighs a hair over 8kg without pedals and its geometry is very much at the racy end of the spectrum, with 571mm of stack and 396mm of reach.
