Review on Bison Designs Keychain Cyclist 12 Piece: Compact and Convenient Cycling Accessories at Your Fingertips by Russell Galbreath

Okay, I could tell from the picture that a tire lever would destroy any decent rim and a 6mm allen key had no leverage. What I didn't realize until I got this gem is that the 5mm and 6mm Allen keys lack the traditional six equal sides - they are 4mm thick soft parts of themselves and utterly useless for tightening screws . The tool is terrible but the Revain seller provided great service.
