Allegra X1 700c Gravel Tire

The Onza Allegra X1 is a fast-rolling gravel tire for riders who spend most of their time on pavement and hard-packed gravel but still want dependable cornering grip when the road turns to dirt. Its smooth center tread helps maintain speed on paved sections, while the progressive shoulder knobs provide extra traction when leaning into corners on gravel. Tubeless-ready construction and a lightweight, supple casing make it a good choice for mixed-surface rides where efficiency matters.

Key Features

• Semi-slick center tread reduces rolling resistance on pavement and hard-packed surfaces
• Progressive shoulder knobs provide grip and control through gravel corners
• 120 TPI GEC casing balances flexibility and durability
• Tubeless-ready construction allows tubeless setup with compatible wheels and sealant
• Folding Kevlar bead keeps weight down and makes installation easier
• Single-compound rubber balances rolling efficiency with predictable traction
• Available in black or tanwall options

Who It's For
The Allegra X1 is for gravel riders who prioritize speed on pavement, smooth gravel roads, and hardpack rather than aggressive off-road traction. It's especially well suited to mixed-surface rides with long paved stretches, fast dirt roads, and occasional light gravel. For looser or more technical terrain, consider pairing it with a more aggressively treaded front tire.
