A triple whammy within a mile.

Riding an Orbea Terra gravel bike, year and a half old today.
32 mile hilly route. 25m into route, I get this vague rattly noise. Eventually spot broken spoke on cluster side. Wind around other spoke.
One mile later, chain breaks. I'd inspected it at start of ride, was fine. Turned bike upside down and got out my chainbreaker. Didn't have spare pin but did a perfect fix on this 10 speed chain within 5 mins. Delighted with myself. Went to pedal off.
Wheel wouldn't turn. What the hell. Took some inspection to spot the problem. The broken spoke had become free and had managed to get stuck in one of the holes of the brake disc. What?!! yes. Took it out altogether. Now sorted! No.
Tried to pedal off. Pedal crank getting blocked by something.
The front derailleur, Shimano GRX had cracked at its upper pivot and was blocking the crank.
I've never heard of, or had such an occurrence before.
Managed to buy a replacement derailleur this afternoon. Will replace cluster (has had 3 chains through it) derailleur chain and gear cable as I'm at it, tomorrow.
What caused what?

Re: Bicep Tendon Tendinitis

I got bilateral biceps tendonitis as a side-effect of an antibiotic which can cause tendonitis.
It was bad for about three months and grandually subsided. I rubbed it and all that kind of thing. It was completely gone in one and a half years on one side and in two years on the other but was really only a minor inconvenience after three months. It did restrict how far around my back I could reach to scratch until gone.
I was delighted it went because I could find no medical article on line on the resolution of antibiotic induced tendonitis.
Soft tissue injuries nearly always resolve in time and it's a characteristic that they affect you less often until you suddenly notice they are gone.
I can't recall mine affecting me much, cycling, but it was more than 10 years ago..

Re: High speed wobble today - advice?

I've had a bad shimmy on two bikes. In the carbon framed racer it occurred on a particular hill with a bad surface. What I learnt with repeating is that if I moved my hands from the bars to the hoods. It stopped. Reproducibly.

Second bike was my tourer. A Thorn Raven Tour. WIth the original tyres which were fattish 26in Panasonics didn't happen. I then rode for years with Specialized Fatboys, it occurred on some hills. These were 1in tyres. When these were no longer available I went of Schwalbe Kojaks and it didn't happen since. Tyre width was the variable here.

Re: Your longest and hardest ride?

1996, longest day of the year. I was 46 and my pal was just over 50. We were back from the Alps.
Did Ring of Kerry from Cork at average speed of 14mph on touring bikes. 215 miles.
Ate loads of food. Felt fine during it and I was absolutely shattered for a week afterwards. Fell asleep four times during the subsequent day, which was a Sunday.

The tool I needed didn't exist...

Jammed wire head in grx lever couldn't be retrieved using any pliers I had. With lower cover removed I could see it up there but couldn't grip it. I'd cut the wire so all I needed was something with a hook.
Safety pin bent with pliers..

There's no end to it!
Had an infuriating creak on a tour. A bikeshop couldn't find the cause. I eventually did. Rear skewer was too tight. Loosened it a little. End of problem!

Re: Bottom bracket creak NOT!..a follow up

After a couple of days a creak came back. I identified the cause. Left pedal screws were slightly loose. Tightened the hell out of them. Then a day later another creak. Did trick Sebastian did in bike shop. Held bike with left hand and forced wheel side to side. It creaked. Five seconds to fix this. The rear thru axle wasn't tight enough. Totally silent again. One of those tightened by a cam lever.
That test is REALLY USEFUL TO KNOW.

Shimano stuff cracks too. A friend has had two Shimano cranks crack. I've only had shimano freehubs since they came out. First problem one.

Never heard of such and I was an early adopter of the cassette. Never broke an axle in one.
Freehub bodies can crack.
Wow - that's a new one!

Re: Bottom bracket creak NOT!

Not sure. Didn't examine it. Bike Merida big nine 4000 from 2016. Shimano hubs according to specs though unmarked.
The difference on cycling is amazing since the repair. Big is running noticeably faster.

Bottom bracket creak NOT!

Modern carbon fibre framed 29er with thru axles develops prominent creak standing up. Cassette appears tight. Axles cleaned, no difference. Must be creaking BB.
Take to bikeshop here in Spain. No!
Diagnosed by Jesus, the owner of Bike Fabrik Lepe, a terrific bike shop as broken freehub body. Replaced. Bike now totally silent.

Re: Pedals flat recommendation please

Catalyst pedals are very good. Longer than usual. I have them on my tourer but they're expensive.
