Orbea Terra H40 Gravel Bike 2023
Matching value with performance, the Orbea Terra H40 Gravel Bike features a hydroformed and triple-butted aluminium frameset for durability across all terrain. Although less exotic than the more premium carbon editions, the aluminium frame is exceptionally lightweight and features confidence-inspiring geometry to offer versatility across a multitude of surfaces. Lively and fast, the frame is rigid for rapid acceleration, and the carbon fork damps vibration to reduce fatigue on longer rides.
Designed to eliminate chain slap for a near-silent ride, the GRX 10-speed drivetrain features a rear derailleur with an integrated stabiliser mechanism, providing additional chain security on rough terrain. Hydraulic disc brakes offer phenomenal stopping power and excellent modulation, while the Orbea OC1 wheels fitted with 38c Vittoria tyres enhance comfort and traction when riding on looser surfaces, and the flared handlebar is wider to improve stability.
