Shamal Ultra wheels
Remember that image of Miguel Indurain speeding to another crushing time trial victory in more than one of his five early 90s Tour de France victories? Well those highly polished aluminium wheels he was riding were the original Shamals, which were ground breaking at the time for being one of the first assembled wheels whose component parts were all created specifically for them. Things have moved on a bit these days, but the Shamal continues, and offers similar weight to a mid-range carbon wheelset, making it truly race-worthy.
The new Shamal Ultra C17 can call on great pedigree, since the model has previously innovated differential rim heights, the G3 spoke pattern, oversized drive side flange, USB ceramic bearings, MoMag magnetic nipple fitting technology, oversized aluminium aero spokes, 2-Way Fit rim profiles and Rim Dynamic Balance.
But for 2016, there's a new 17mm internal width, up from 15mm, which is designed to create a more aerodynamic profile specifically with 25mm or 28mm tyres, as well as a larger tyre contact patch, more comfort thanks to greater air volume, and increased rigidity and reactivity. The front hub body is carbon fibre, and both hubs have USB ceramic bearings with an adjustable lock ring – first seen on the Bora wheelset – for preload adjustment.
The drive side rear flange is oversized, and there are 16 radial anodised aluminium spokes up front, with 21 behind in the Mega G3 pattern, and Campagnolo's anti-rotation system ensuring they don't turn in use. Chrome finished self-locking nipples look good and can be adjusted conventionally, while the rims are lightened through toroidal milling, which shaves away metal where it's not needed.
They'll be offered in clincher and 2-Way Fit (tubeless) versions, and claimed weights are 1,435g per pair for the clinchers, and 1,515g for the 2-Way Fit version.
