from reading the thread about vices & stuck BBs and intending to service my winter bike this weekend if it is sunny (?) how often to people remove their BB to check, re-grease and re-install it? annually?
their seatpost?
quill stem? (if have one)
do you check your 'bars for corrosion?
cables?
pedals?
do you check rims for cracks?
brake blocks?
that type of thing.
as i like preventative maintenance i'm always interested in the way bikes are maintained by experienced cyclists.
(out in all weathers, commuter type bike really but anything on the road.)
cheers
Annually, on my regular bike. And I don't even ride in the rain that much.
1. Remove all components leaving bare frame.
2. Usually, spray inside of frame with Dinitrol, using lance. This year will be the 3rd time (or maybe 4th) I've done this, once the Dinitrol can is empty I probably won't bother again.
3. Strip hubs, inspect, replace balls (grade 10) and grease (Silkolene RG2), adjust.
3a. (sometimes) remove free hub, remove rear seal and squirt SFG into it. Probably won't do that too often. These days I usually put some SFG into the RHS cup, spin the freehub, and hope it finds its way into the freehub.
4. Inspect headset. Not felt the need to replace or re-grease yet. It's loose balls (Grade 10) and Comma CV joint grease. Adjust.
5. Re-fit bottom bracket, with either thick grease or anti-seize.
6. Squirt a small amount of SFG into STI mechanism.
7. Dribble a small amount of Triflow into the ends of all cables. Then refit cables.
8. Inspect and replace brake pads if necessary.
9. Remove and refit seatpost. But I don't make too much of a fuss, as it's steel, so I'm a lot less concerned about galvanic corrosion (it's a steel frame).
Then I put everything back together, and adjust brakes and gears etc.
I'll go round the bike looking for bolt heads susceptible to rust, and blather a bit of grease on them, especially into the actual hex hole (then shove a hex key into it to squash the excess out). Triflow on derailleur joints, maybe. A bit of silicon grease on some of the plastics, maybe. Then go round with a kitchen towel wiping things down.
I haven't serviced the brakes callipers yet (BB7s).
I've only done the jockey/guide wheel bearings once. I probably won't bother again unless the bike has got very wet/dirty or I feel I need to. I've got a spare pair anyway.
Yes, for the relatively low mileage and good conditions this bike is used in, it is hugely over-mainatined. But I want it to last, and I don't have problems with it. Also I quite like getting out on the patio and fiddling.
