Crank Brothers S.O.S TT17 Tool Kit

Yes, the TT17 includes a dedicated tire plug tool and two plugs, allowing you to seal punctures on the trail without needing to remove the tire.

The kit is designed to be compact, but it is essentially a small, rigid tube. While it fits in most jersey pockets, it is often more comfortable and secure when stored in a saddlebag or strapped to your bike frame.

Yes, the storage tube is specifically engineered to house a 16g or 20g CO2 cartridge, along with a spare chain link, keeping your emergency supplies organized in one place.

Yes, the integrated chain tool is compatible with most modern bicycle chains, including 12-speed drivetrains, making it a reliable choice for trailside repairs.

The wrenches are sized for standard bicycle maintenance and adjustments. While they are sufficient for most common trailside tweaks, they are compact by design, so they may not offer the leverage of a full-sized shop tool for seized or heavily torqued bolts.

The CO2 head is designed primarily for Presta valves, which are standard on most performance mountain and road bikes.
