Luteus II is an all-carbon-fiber fork for cross, gravel, and adventure bikes and supports 700c or 27.5" wheels. This second-generation Luteus builds on its forerunner that’s been extensively proven in top-level cyclocross racing and is now fitted with 15 mm thru-axle fork ends. The left fork blade is reinforced around the brake mount posts to counteract torsional braking forces even from 180 mm diameter disc-brake calipers; tapered 1 1/8" — 1 1/2" steerer provides ultimate strength and stable, accurate steering in even the most challenging terrain. Luteus II has clearance for 700c gravel/cross tires up to 44 mm width or 27.5" mountain bike tires up to 2.1" width.
