Lightweight marvels with optimal balance
In the world of cycling, weight is a crucial factor. The Explorator GCR40 wheelset weighs in at 1016 grams for the rear wheel and 852 grams for the front wheel, striking a harmonious balance.

Whether you're a weekend warrior or a dedicated road training enthusiast, these wheels are your ideal choice to maximize the joy of cycling.

Rims that redefine durability
The heart of any wheelset lies in its rims, and the Explorator GCR40 doesn't disappoint. Crafted from a specific Niobium alloy with a T10 heat treatment, these rims are ultra-strong and durable. The 40mm aero profile offers a 21mm inner width and a deep 9mm inner drop. This design not only makes installing difficult tires a breeze but also ensures a better fit for wider tires. The rims provide excellent stability for tires up to 40c. But what sets these wheels apart is that they come tubeless ready right out of the box. Say goodbye to tire setup hassles and hello to puncture-resistant, lower-rolling-resistance rides.

The power of Sapim Leader Spokes
These exceptional wheels are built with Belgium-made Sapim Leader spokes, composed of Swedish stainless steel, and paired with black nipples. The result? A wheelset that's not just about performance but also value. It's a package that's hard to beat.

Hubs: The core of excellence
At the core of the Explorator GCR40 wheelset are the X12 24-hole IONA front and rear hubs. These IONA straight pull hubs are supported by high-quality industrial bearings and a 4-pawl ratchet system. For those who demand the absolute best, an upgrade option is available with SKF bearings or even ceramic bearings. Moreover, you can choose freehub bodies for Shimano HG/Micro Spline, Sram XDR, or Campagnolo/Ekar, making them incredibly versatile and compatible with various setups.

A stylish upgrade for your bike
