Compound comparison
A resole is the one time you get to choose your compound. Every rubber trades friction against edge support against lifespan — here's how the ones your resoler can actually buy stack up.
| Compound | Maker | Character | Friction | Edge support | Durability | Common thicknesses | Best for |
|---|
Ratings are relative, bench-and-wall consensus among member resolers — not lab numbers. Every compound here is genuinely good; the question is what you climb.
Quick answers
A soft, high-friction compound — Vibram XS Grip 2, Unparallel RS, or Mad Rock Science Friction. Maximum smear and hook, shorter lifespan.
A firm compound — Vibram XS Edge or Unparallel RH. Crisp micro-edging, holds an edge shape longer, and shrugs off cracks.
Split the difference: a firm compound in 4mm, or a grippy compound in a thicker cut. Ask your resoler what wears best at your gym — they see the evidence daily.
The elephant in the workshop
Five Ten's Stealth compounds (C4, HF, Mi6) are only applied at the factory — the rubber isn't sold to independent resolers. If you love your Hianglés, they'll resole beautifully in another compound; most climbers land on XS Grip 2 or UP RS as the closest neighbors. Keeping repair-grade materials available to independent shops is exactly the kind of issue this coalition exists to work on.
