Two new releases from Parcours, including the surprising Grimpeur carbon rim brake wheels

ByStan Updated on

Parcours, the renowned British brand known for its carbon wheels blending performance and affordability, is making waves in 2025 with two significant releases. On one hand, a Ratchet mechanism integrated into its premium road and gravel ranges. On the other, a reinvented Grimpeur wheelset for rim brakes, modernized with the #thinkwider technology. These innovations reflect Parcours’ commitment to delivering advanced technical solutions to all cyclists, whether they’re competitors or passionate enthusiasts.

The new Parcours Star Ratchet system

Parcours is introducing a ratchet-based system into its premium hubs, an upgrade that replaces the older pawl design. Featuring 36 teeth, this mechanism ensures quick engagement—ideal for technical restarts on challenging terrain—while guaranteeing long-term durability. The design increases the contact surface under load, reducing the risk of slippage even during intense efforts like steep climbs or sprints. This system now equips both road (disc and rim brake) and gravel wheelsets. A nice bonus: hub bearings can be accessed without tools, making maintenance a breeze for those who want to keep their wheels in top shape without a trip to the shop.

Technical specifications :

  • Disc hub weight: 115 g (front), 220 g (rear with Shimano HG body)
  • Freehub body options:
    • Disc – Shimano HG, SRAM XDR, Shimano Microspline
    • Rim brake – Shimano HG, SRAM XDR
  • Engagement: 36 teeth for an optimal balance of responsiveness and durability

Grimpeur 2025: Rim brake carbon wheels finally level up

Fans of rim brakes will love the reimagined Grimpeur wheelset for 2025. Parcours incorporates its #thinkwider technology, widening the rim for the first time in this category. With a 41 mm profile, an external width of 29.5 mm, and an internal width of 22.5 mm (matching its disc models), this wheel meets a growing demand: riding wider tires without sacrificing aerodynamics. CFD simulations show that with a 25 mm tire, it performs within 0.5 W of the Passista (56 mm), while outperforming it by an average of 1.5 W with a 28 mm tire. The cherry on top: despite the wider rim, the Grimpeur 2025 dips below 1300 g.

Technical specifications :

  • Profile : 41 mm deep
  • External width : 29.5 mm
  • Internal width : 22.5 mm
  • Weight : 1300 g (575 g front, 720 g rear)
  • Hubs : Equipped with the 36T Star Ratchet mechanism
  • Optimized for : 25-28 mm tires
  • Price : €1429

These innovations aren’t just updates—they address real needs. The Ratchet mechanism has become an industry standard for its efficiency, offering responsiveness and easy maintenance that will appeal to regular riders and competitors alike. The Grimpeur 2025 modernizes rim brake wheels with a wide, lightweight rim, perfect for climbers or fans of long, rolling rides.
