The P-SLR1 Aero boasts 50mm-deep carbon fibre rims with a scandium braking surface, own-brand hubs (with DT Swiss star ratchet internals at the rear) and bladed stainless steel spokes (16 front, 20 rear) with hidden nipples. An asymmetric rear rim is said to increase the wheel’s stiffness, strength and durability by maintaining spoke bracing angles. Weighing in at a claimed 1,575g, the set costs £1,249.99.
Giant say the non-aero version, the P-SLR1, is engineered for a stiff yet comfortable ride, with all of the design features of the aero version except for the deep-section rims. The rims are scandium rather than carbon and, as with all of the company's new road wheels, are 21mm wide – Giant say this allows for lower pressures with less risk of pinch flats. Combined weight is 1,390g and RRP is £749.99. You can read more about both P-SLR1 wheelsets here.
The new aluminium P-SL0 wheels are said to be light enough to race on and tough enough for everyday training, and retail for £449.99. They have the same wide-flange front hub and asymmetric rear rim as the P-SLR1, and weigh just a fraction more than the carbon aero model, at 1,595g. As with the two pricier wheelsets, they're tubeless ready.
The entry-level P-SL1 (£224.99) is said to have been designed for performance road riders who are considering racing. 6061 alloy rims are laced with DT Champion spokes (18 front, 24 rear) to sealed-bearing hubs, and they weigh in at a claimed 1,775g for the set. All four wheelsets will start appearing in shops from September.
