🌟 Key Features

1. 🪶 Incredible Lightweight Performance (Save ~267g!)

Say goodbye to heavy stock alloy cranks! Taking the original JAVA Neo alloy crank with a 50T chainring as an example, the total weight is a hefty 784g. By upgrading to this RPANTAHI set (165mm crank + 54T chainring), the total weight drops to just 517g!
👉 That's a massive weight saving of approximately 267g, giving you a remarkably lighter feel during acceleration, climbing, and sprinting.

2. 💎 Premium Build: Carbon Fiber + TC4 Titanium Spindle

The crank arms are constructed from high-strength carbon fiber, offering not only a stunning carbon weave aesthetic but also exceptional stiffness. Paired with a cost-no-object 24mm TC4 titanium spindle, it provides superior strength and toughness at a fraction of the weight. Sprint with absolute confidence knowing no pedaling power is wasted.

3. ⚙️ RIRO Carbon Composite Chainring (52T / 54T)

Designed for speed seekers, this bundle offers 52T and 54T large chainring options—especially ideal for minivelos and folding bikes to boost top speed. The carbon composite material perfectly balances durability and lightweight design, ensuring precise chain engagement and direct power transfer.

4. 🌪️ RIRO Ceramic Bottom Bracket (BSA 24mm)

The set includes a BSA 24mm ceramic bottom bracket. Ceramic bearings offer incredibly low friction resistance and higher durability compared to standard steel bearings, making every pedal stroke buttery smooth and minimizing power loss.

5. 🛠️ Excellent Compatibility & Power Meter Ready

Featuring a universally friendly 24mm spindle, most riders can install this directly without changing their frame's bottom bracket standard. The 110BCD*4 spider is compatible with Shimano chainrings, and its modular design even supports direct mounting for EASTON-spec power meters!
