That reminds me. I must check my rim wall thickness soon before I have another explosion.
When pretty much all the black's worn off your black mavic rims, does that mean it's time to start thinking about new rims?
No. You can usually tell by touch if a rim is well worn, as the braking surface will feel noticeably concave. When it's near failure you'll often find that the flange starts to flare - it's a bad idea to use a rim in this state, as simply inflating the tyre to maximum pressure will often split the rim. I've seen it suggested that if you think a rim is near the end of its life you can overinflate the tyre by 50% to see if this causes failure. If you do this you should wear eye (and preferably ear) protection, and leave the wheel somewhere safe for a while - if it doesn't explode, don't do anything with it until you've reduced the pressure again.

Thanks - noted. You remind me of when I got my track pump and decided to do 'er indores a favour by firming up the tyres on her old Raleigh sit up & beg...I was back working on the PC upstairs when I heard a distant but distinct 'bang'. Uh-oh, I thought. Which proved entirely justified...

You have to be careful with pressure on older rims that don't have a hooked bead to retain the tyre - they are less tolerant of overinflation.
Yes they do, I use this combination - they all seem to be compatible to the Shimano system (XT?).
Very timely. My back brake started making a scraping noise this morning and I discovered the pads were completely worn away. I'm thought it's not that long since I checked them, but I guess with it being dark all the time I hadn't looked for a while. Rode using front brake only and will need to make a distress purchase today for immediate fitting.
