With more tire clearance and more capability, today's gravel bikes can take on tougher trails than ever before. The Rhombus Pro delivers unmatched traction, confident cornering, and improved comfort when the gravel road turns to single track. When you're ready to get rowdy on your gravel bike, the Rhombus Pro is the tire for you. Aggressive Tread Design: Large center and shoulder knobs for unmatched traction on loose surfaces. Gripton Compound: Specialized's legendary grip compound for confidence in corners and under braking. Endurant Flat Protection: Gravel-specific puncture protection — lighter than Armadillo, tuned for off-road hazards. 2Bliss Ready: Tubeless-compatible with easy setup and reliable seal. 60 TPI Casing: Durable construction designed for aggressive off-road use. Wide Sizes: 700x42C and 700x47C — maximum volume for confidence on rough gravel and singletrack. Use: Aggressive gravel riding, gravel racing, when the road turns to dirt. The Rhombus Pro is for riders who push hard and need grip on loose, rough terrain. Pair with Pathfinder on the rear for a balanced setup — Rhombus front / Pathfinder rear is a popular combo. Gravel + Aggressive = Rhombus Pro The Rhombus Pro is Specialized's aggressive gravel tire — designed for riders who go where the pavement ends. The tread pattern is more aggressive than the Pathfinder or Tracer, with larger, more widely-spaced knobs for maximum traction in loose conditions. Multiple reviewers use it as a front tire paired with a Pathfinder on the rear — giving them the grip they need up front and faster rolling in back. If you ride genuinely rough gravel or light singletrack, the Rhombus Pro is built for that. Mud Warning One significant limitation: the Rhombus Pro is not a mud tire. Multiple reviewers note it cakes up fast in wet, sticky mud — one says "1/10 if you encounter mud" vs "10/10 dry conditions." The open tread pattern that works so well in loose gravel and dirt doesn't shed sticky mud well. For muddy gravel rides, look at the Tracer or Terra TLR instead. Endurant Protection Endurant is Specialized's gravel-specific flat protection — lighter than the Armadillo construction used in their road endurance tires, but tuned for off-road hazards like small rocks and thorns. It's the right balance for gravel: enough protection for rough rail-trail riding, without the weight penalty of road-specific Armadillo protection. Reviewers confirm it works — one racer finished 700 miles of Unbound XL with a puncture that quickly sealed, not noticing until post-ride.
