@Half-Fast Mike That’s good to read they helped. My dad had some injections but he felt they didn’t do much.

Regards my injury, I still have some inflammation in the joint and occasional clicking and locking when I move it (non load bearing). I’ll continue with the physio and swimming and see how it feels when I go back to the doctors next month.

quick Q about the area where the pads hit the rotors. my rear rotor shows wear marks from the very start of the braking surface, while the front marks only start about 2mm inward to the hub side. why such a discrepancy on a part one would expect doesn't tolerate much deviation (setup is the same F/R) and is this something one should worry about?

Think the system has some allowance for slop. Should be ok. However check your rear pad is making full contact. If there’s a part that overhangs over time there will be a ridge worn into it. When the ridges on both sides meet in the middle your brake will lose power.

Great point. I noticed this on my CX bike rear brake (still mounted with washers and stuff from the hardware store instead of a proper Shimano 140-to-160 adapter). The ridges on the pads peeled off with just finger-pressure, but were enough to stop the brake working properly until then. (Knowing this means I can continue to be lazy about buying that part...)

can't believe that's a thing, but thanks for letting me know. had a quick look just now, but could not immediately confirm. I might need to wait till there's a bit more wear in the pads...

About putting a disk brake bike in the train bag (rinko). Has anyone experienced this, and how to prevent it: rotors getting contaminated by the drive-train lube which might rub off on the right side of the bag first, then gets to the left, rotors side once the bag is folded... Or am I just overthinking it?

Might be getting a little too paranoid, but you can try a disposable shower cap over the rotor.

never had a problem as the grease is at the bottom of the bag and the rotors are half way up the bag. I guess a plastic bag over the rotors if you're really worried.

not really sure. the cassette and RD with the chain going through there are all at about the same position as the rear rotor. so it seems very probable some of the lube would rub off on the drivetrain side of the bag. then when you fold it, it's gonna match with just about the rotor position on the left side of the bag... so it's plausible at least, but it looks like it's not happening so I'm happy to give it a go and see

I've probably done 50 or 60 rinko journeys with DB adventure bike and my filthy MontBell bag. No signs of braking problems or contamination so far.

I tend to strap the front wheel to the frame with the disk facing inwards. I haven't really given much thought as to whether that's the best orientation for it. The rotor nestles on the water bottles.

I like @Cactaur's idea of a plastic shower cap. Or if you want to spend more money, Amazon's got you covered...
