Here's a list I put together for my mechanics class
-->Tool list
General tools
· Allen wrenches (in mm)
- 4, 5, 6 most common
- 8, 3, 2.5 useful to have
- Torx
· T25 most useful
· Metric combination wrenchs (box end/open end)
- 15mm most useful
- 8 to 17mm handy to have
· Large adjustable wrench
· Soft headed hammer
· Screwdriver
- Phillips. JIS standard works better for most bicycle applications
- Flat
· Side cut wire cutters
· Hacksaw
· Needle nose wire cutters
- Park has a good pair with a built in crimper for cable ends
Bike specific tools
· Pedal wrench
- 15mm combination will work in a pinch
- 8mm Allen wrench may be needed for some pedals
· Chain tool
- Should be able to handle the chain you use.
- 9 speed chain tools may not be able to be used on 11speed chains
· Chainwear checking tool.
· Master link pliers
· Chain whip
· Lock ring tool or freewheel tool
· Cone wrenches
- 17, 15, 14, 13 mm
- 17mm combination will work on lock nuts
· Cable cutter
· Bottom bracket tools
- There are several. Get the one that matches your bottom bracket
· Spoke wrench
- Combination ones that fit 3 different spoke widths work well for limited home use
· Headset tools
- There are several. Match your headset
- May be as little as a 5mm allen wrench.
· Tire levers
Bike specific tools that are nice to have but not absolutely necessary
· Repair stand
- PCS 10 is good
- PSC-4-1 is better but more expensive
- PRS-3.2-1 is the best but it’s very expensive and needs an additional expensive base. You’ll be giving it to your great-great-great grandchildren, however.
· Truing stand
- Sunlite makes a foldable one that works well ($50)
· Torque wrench and allen bits to fit
· Park Adjustable Torque driver
- Necessary if you have carbon parts
Bike specific tools that are handy but you’ll probably never use
· Headset press
· Crown removal tool
· Crown press
· Derailer hanger alignment tool
· Fork cutting guide
· Star nut setting tool
· Dishing gauge
Bike specific tools even
Idon’t have
· Facing tools
· Frame alignment tools
· Bottom bracket threading/facing tools
The last ones are highly expensive (~$500 each) and have limited use.
