21 point Maintenance Check!
Every Month 21-point maintenance check
1. Wipe down the entire bicycle with a wet rag.
2. Clean rims.
3. Clean and treat leather saddles with saddle soap or leather dressing.
4. Degrease the chain, cogs, and chainrings.
5. Check frame, rims, crank, fork, handlebar, and stem for cracks.
6. Check crankbolts and chainring bolts for tightness.
7. Check cables for kinks and fraying.
8. Check tires for excessive wear.
9. Check stem bolt: Hold the front wheel of the bicycle between your legs and try to turn the handlebar with one hand; if it moves easily, tighten the stem bolt(s).
10. Check that all brake hardware is secure.
11. Check headset for proper adjustment.
12. Check rear suspension pivot bolts for proper torque (if you have suspension).
13. Check accessory hardware (racks, bottle holders, etc) for tightness.
14. Check chain: Measure the chain and check the cogs and chainrings for excessive wear; replace if necessary. (Covered in Intermediate Maintenance class)
15. Check brake pads. Adjust as needed. Replace if excessively or unevenly worn.
16. Check the spoke tension and trueness of wheels. Adjust as needed.
17. Lubricate suspension dust wipers to keep them from drying out (if you have suspension).
18. Lubricate the chain.
19. Lubricate rear and front derailleur: bushings of the idler and jockey pulleys on the rear derailleur; pivot points on the front and rear derailleur.
20. Lubricate pedals: springs and pivot points on clipless pedals.
21. Lubricate hub: Add 2-4 drops of oil to three-speed hubs.
Clean –> Check –> Adjust/Replace –> Lubricate

Cleaning, Inspection and Lubrication
Cleaning, Inspection, Lubrication
Cleaning Supplies
Basic
1. Water based cleaner e.g. Simple Green
2. Citrus or Soy based degreaser: Ecotech
3. Containers for solvent: spray bottle, small bottle w/pipe
4. Toothbrushes
5. Rags
Optional but very helpful
1. Work stand: Topeak Flashstand, Park PCS-10
2. Chain bath/scrubber tool: Park Cyclone
3. Gear cleaner brush: Park GSC-1C
4. Protective latex/nitrite type gloves: Park mechanic’s gloves
5. Apron
6. Emery cloth
7. Rubbing alcohol
8. WD-40: dissolves rust!
9. Pledge/spray wax
10. Chain tensioner
Inspection Checklist
Look over frame and components for cracks, especially:
o Frame joints, Dropouts, Handlebars
Wheels:
o Tires, Rim sidewall wear/damage flattened rim
o Cracks at rim and hub spoke holes
o Loose/broken spokes
o Hub bearings – spin and check for roughness
Drivetrain, check for:
o Chain/gear cluster wear, Obviously damaged, bent components
Lubrication - Wipe of all excess lube – it just attracts dirt.
o Use lightweight oil e.g. Triflo
o WD-40 is a solvent, NOT a lubricant
o Lube moving metal to metal contact points
o Chain bushings
o Derailer pivots and jockey wheels
o Brake arm and lever pivots

Basic Week 2 - Flat Tires
A few things to look over on flat tire repair:
1.ParkTool's guide: http://www.parktool.com/repair/readhowto.asp?id=100
2. And here's a video of the process: http://bicycletutor.com/fix-flat-tire/
3. If you have some extra time, this is an exhaustive (and exhausting?) article on tires, tubes and air pressure: http://www.sheldonbrown.com/tires.html

Basic Week 5 - Brakes!
Some helpful tips about BRAKES!
Determine what type of brake you have and then watch the corresponding video on how to adjust your brakes (feel free to watch the other videos as well!) We'll be using a slightly different method during our activities, but the videos will give you an idea of the process.
sidepull:
www.bicycletutor.com/sidepull-caliper-brakes
Cantilever:
www.bicycletutor.com/adjust-cantilever-brakes
FYI: this type of brake, by far, takes the most time to replace (or even just adjust) brake pads and replace cables. Linear Pull/"V brake":

Centerpull: I haven't been able to find a video for this style. However, centerpulls adjust in a similar fashion as sidepulls, so watch that video.
