Muc-Off Bio Grease 450 g - Review

 Introduction

Muc-Off Bio Grease 450 g is a premium, biodegradable bike grease specially formulated for “low-speed” bicycle components like bottom brackets, headsets, hubs, pedals, and crank bolt. Crafted for cyclists—whether home mechanics or serious enthusiasts—who value eco-friendly, long-lasting lubrication, this grease serves anyone seeking high performance and corrosion protection in wet environments.

Design & Build Quality

The 450 g tub features an ultra-slippy, biodegradable formulation free from petroleum-based oils. Its creamy, strawberry-jam-like consistency makes application simple. Particularly water-resistant, it holds firm under moisture, ensuring reliable lubrication even in challenging weather.

Performance & Features

Performance-wise, Muc-Off Bio Grease excels at reducing friction and resisting wash-off in wet conditions, thanks to its hydrophobic, biodegradable blend. In long-term testing (18 months in harsh conditions), components like headsets, hubs, and suspension parts remained smooth and functional—with visible grease still intact upon disassembly. Its pleasant scent, likened to strawberry toothpaste, adds a user-friendly flair.

Pros, Cons & Verdict

Pros:

• Biodegradable and eco-friendly — safe for seals and composites.
• Exceptional water resistance and long-lasting lubrication.
• Pleasant fragrance and user-friendly consistency.
• Proven durability over extended, real-world use.

Cons:

• Might be too soft for heavily threaded or high-load zones like bottom brackets—some prefer stiffer polymer grease there.
• Nozzles could be finer for pinpoint application—Cycling Weekly noted this minor usability drawback.

Verdict

Muc-Off Bio Grease 450 g is a top-tier biodegradable bike grease delivering excellent water resistance, smooth performance, and eco-conscious appeal. Recommended as a maintenance staple for most bicycle components—especially for those focused on lasting protection and environmentally responsible gearkeeping. Just complement it with a thicker grease for high-stress threaded areas.
