Pedro's Tutto Bicycle Multi-Chain Tool - 3-in-1 Bike Chain Cleaner, Lubricator & Maintenance Kit for Road & Mountain Bikes - Perfect for Home Garage & Outdoor Cycling Repairs

This is the first review I've felt compelled to write. I needed to break my 9-speed Shimano chain to install a new front derailleur, and tried tools by Park (CT-3), Topeak and Leyzane. I'm over 50, and with my eyes it was hard to tell when the pin was aligned properly. All three of those sheared the pin. Pedro's tool aligns the pin for you, is heftily built, and completed the job in 3 minutes. The Pedro's tool is capable of handling much more than I need (single-speed, Campy 11-speed), but it succeeded where other tools failed. The lifetime warranty makes Pedro's my first choice for bike tools in the future.
