Schwalbe Ice Spiker Pro 29x2.25W

The Schwalbe Ice Spiker Pro 29" x 2.25" is widely recognized as the ultimate mountain bike tire for extreme winter trail riding and icy commuting. Packing up to 402 strategically placed spikes, it converts slick sheets of frozen singletrack and hardpacked winter roads into high-traction pathways.

Key Specifications & Features

• Massive Stud Density:
  Outfitted with 402 studs per tire in the 29" size. Each spike features an ultra-hard tungsten carbide core wrapped in a weight-saving aluminum cladding to preserve agility without dulling.
• Double Defense (DD) & RaceGuard:
  Combines a dual layer of nylon protection beneath the tread with reinforced sidewalls to safeguard your casing from jagged ice shards, hidden roots, and rocks.
• Tubeless Easy (TLE):
  The folding bead variant features a TLE carcass, letting you ditch the inner tubes to run lower air pressures for an extended contact patch over uneven winter snowpacks.
• Winter Silica Compound:
  Crafted using a cold-weather-optimized rubber compound that remains supple and adhesive even when temperatures plunge deep below freezing.

Performance Profile

• Best Suited For:
  Glare ice, frozen lakes, deeply rutted winter trails, and packed snowy infrastructure.
• Pros:
  • Unrivaled mechanical traction on sheer ice.
  • Decent self-cleaning spacing to shed slush.
  • Relatively lightweight for a high-count studded tire.
• Cons:
  • Noticeable rolling resistance and structural noise when transitionally crossing bare asphalt.

This tire is engineered to dominate the harshest winter terrains while maintaining agility and performance.
