Ere Explorator II GCR40 Alu Disc Wheelset

Whether you’re attacking fast road sprints, climbing steep hills, or enjoying long weekend rides on light gravel, the GCR40 wheelset is designed to enhance every pedal stroke, delivering unmatched control and efficiency.

The heart of the wheelset lies in its 40mm aero Niobium alloy rims with 21mm internal width and a deep 9mm inner drop, providing superior stability and a perfect fit for tyres up to 40mm. Tubeless-ready straight from the box, these rims reduce rolling resistance and improve puncture protection while accommodating a wide range of tyre options. Paired with Belgium-made Sapim Leader stainless steel spokes, the GCR40 ensures a strong, reliable, and lightweight setup, allowing for precise handling and enhanced durability across all road conditions.

IONA hubs

Compatible with Shimano HG/Micro Spline, SRAM XDR, and Campagnolo/Ekar freehub bodies, these hubs offer incredible flexibility and long-term reliability. Finished in a sleek anodised matte black, the GCR40 not only performs brilliantly but also adds a striking, modern look to any bike. Lightweight, robust, and aero-optimised, the Ere Explorator II GCR40 Alu Disc Wheelset is the perfect upgrade for riders looking to push their limits while enjoying every mile in style.
