MRP Teases the Otto - A 38mm Coil Fork

Why It Matters

The Otto introduces a hybrid coil‑air spring design that could set a new performance benchmark for long‑travel forks, offering manufacturers and riders a more adaptable suspension solution. Its launch signals MRP’s re‑entry into full‑chassis development, potentially reshaping the competitive landscape against Fox and RockShox.

Key Takeaways

• Otto offers 150‑180 mm travel for long‑travel and eMTB bikes
• 38 mm stanchions deliver high chassis stiffness
• Uses MRP Lift damper with five tune options
• Speed Spring combines coil with passive air chamber for progressive feel

Pulse Analysis

The mountain‑bike suspension market has long been dominated by air‑based forks, but MRP’s upcoming Otto could shift that balance. By pairing a 38 mm stanchion design with a hybrid coil‑air Speed Spring, the fork promises the ultimate blend of stiffness and progressive feel. The large coil handles the bulk of spring duties, while a sealed air chamber adds a secondary ramp that mitigates harsh bottoming without requiring rider‑adjustable pressure. This architecture aims to deliver consistent performance across the 150‑180 mm travel range, catering to aggressive trail riders and the growing e‑MTB segment that demands durability under higher torque.

Beyond its spring innovation, the Otto incorporates MRP’s Lift damper, a proven unit that offers external low‑speed compression and rebound adjustments plus internal shim stacks for fine‑tuning. With five preset damper tunes, the fork can be quickly matched to rider weight and terrain, reducing setup time for race teams and serious enthusiasts. The inclusion of service ports for direct oil injection further simplifies maintenance, a practical advantage for riders who push their equipment in demanding conditions.

If MRP can deliver the Otto on schedule, the fork could become a compelling alternative to flagship models from Fox and RockShox, especially for riders seeking a coil‑centric feel without sacrificing the adjustability of air‑based systems. Its 2.58 kg weight positions it competitively in the market, while the exclusive 29‑inch wheel compatibility aligns with current trail bike geometry trends. Anticipation is high, and the Otto’s performance will likely influence future suspension design strategies across the industry.
