Pedro's Chain Tool

The chain tool is designed to work with most standard bicycle chains, including single-speed and multi-speed chains. However, it is not compatible with some specialized, ultra-narrow chains found on high-end 12-speed drivetrains.

The tool features three integrated spoke wrenches sized at 3.2 mm, 3.3 mm, and 3.5 mm, which cover the vast majority of standard bicycle wheel nipples.

The 5mm hex key is the most commonly used size on modern bicycles, fitting many stem bolts, seat post clamps, and brake calipers. While it handles the essentials, you should check your bike's specific hardware to ensure you don't require other sizes like 4mm or 6mm for critical adjustments.

The heat-treated steel is highly durable and resistant to bending or stripping under normal maintenance pressure. It is built to withstand the torque required for chain repairs and spoke adjustments without deforming.

Yes, weighing only 80 grams and featuring a compact, streamlined design, it is specifically engineered to be unobtrusive. It fits easily into a standard saddlebag, jersey pocket, or small tool roll without adding significant bulk.
