Unsure which SQ shorts to buy? Our comparison of the ONE12r and ONE12
What sets the ONE12 R apart from the regular ONE12?
Below is a quick‑to‑read rundown of the key differences that matter most on the bike:
| Feature | ONE12 R (the “R” version) | ONE12 (standard) |
|---|---|---|
| Pad thickness | Ultra‑thin 4 mm SQ‑Pad 12 R – stays firm, gives a “riding‑on‑the‑pad” feel | Slightly thicker 5 mm SQ‑Pad 12 – still thin but a touch more cushioning |
| Pad firmness | Form‑stable, high‑density foam that doesn’t collapse under hard pedalling | High‑density as well, but a bit softer than the R‑model’s ultra‑firm core |
| Targeted geometry | Tuned specifically for aggressive, forward‑rotated road positions (aero‑focused riders) | Designed for a broader range of road positions, including more relaxed setups |
| Fabric & compression | Light‑compressive, breathable performance fabric that moves with you while staying close‑fitting | Similar breathable fabric but with a slightly higher stretch profile, giving a bit more “give” |
| Leg grippers & straps | Wide leg grippers + flat, low‑profile straps that lock the short in place without pinching | Same wide grippers, but the straps are a standard design—not as low‑profile as the R’s flat version |
| Intended rider | Ambitious racers and time‑trialists who want the absolute minimum pad bulk for maximum power transfer | Versatile road cyclists who still want a thin pad but may prioritize a little extra comfort on longer, less aggressive rides |
| Overall feel | “Bare‑metal” – almost no sensation of a chamois, just pure, direct contact and power | Very comfortable, still thin, but you’ll notice a subtle cushion under the hips |
Bottom line
- If you ride in a tight, aero position and crave the most direct, low‑friction feel, the ONE12 R’s 4 mm, ultra‑firm pad and flat‑strap design give you that “no‑pad‑in‑the‑way” sensation while still protecting pressure points.
- If you prefer a tiny bit more cushion and a slightly softer ride for long endurance days, the regular ONE12’s 5 mm pad is still incredibly thin and performance‑oriented, just with a marginally softer feel.
Both models share the same high‑quality compression fabric, wide leg grippers, and breathable mesh back, so you get the same durability and ventilation—only the pad thickness, firmness, and geometry tuning differ. Choose the ONE12 R when you want the absolute minimal pad footprint for maximum power transfer; pick the ONE12 when you’d rather have a whisper of extra comfort without adding bulk
