11 & 12. Vise-Whip and Cassette Lockring Tool With Guide Pins and Handle
When it's time to change your cogset, you'll need a combination of tools. You can get by with an old-fashioned chain whip and cassette lockring tool, but Pedro's cool, high-tech Vise-Whip ($70) locks into place on your cog, eliminating the chances of a knuckle-busting slip of a traditional whip. Pair it with the Cyclus cassette lockring tool ($25) that has both Shimano/ SRAM and Campagnolo lockring compatibility built into a single two-sided tool.
A good multitool can mean the difference between making a swift, easy midride adjustment and hobbling home with a scowl. Always carry a palm-sized workshop like the Lezyne RAP 13 ($25), which boasts eight sizes of hex and Torx keys, a Phillips screwdriver, a chain tool, two sizes of standard square spoke wrenches and a third spoke wrench for Mavic splined nipples.
14. Four-Way Screwdriver
Those who appreciate space efficiency and multitasking will dig this tool. Choose a version with quality steel tips that won't round off or strip hardware. The four sizes will fit nearly every flat or Phillips screw on your bike.
15. Spoke Wrenches
With so many wheel manufacturers using unique spoke-nipple designs, it's impossible to recommend any one model. If you have conventional square spoke nipples on your wheels, you can't go wrong with Park Tool's SW-0, SW-1 or SW-2 ($8 each). The design has hardly changed since the 1960s—and that's because it doesn't need changing.
16. Sharpened Spoke
A sharp pick has many uses, from opening the liner on a freshly cut piece of cable housing to poking leaves out of a cogset. You can sharpen the end of a broken spoke with a hand file to make your own. Bend a loop at the other end so you can hang it on a peg board.
