I done something silly, and used red loctite a while ago on the linkage bolts on my frame (meta v4). Do I risk damaging something by using big leverage to get the bolts out?

The bolts and the threads in the frame, but normally the bolt head would snap before it strips your frames threads. Try some different stuff, such as Acetone, the Loctite remover or your standard sprays

If you want a no risk solution, get that Red Loctite off. As per above comment, you can use a chemical solution maybe if it can penetrate. Otherwise, I've had really good results removing red loctite with a heat gun. Doesn't take but 5 mins and it will melt off in my experience. As for your question, i would say yes, you risk breaking something.

My derailleur is having an interesting issue. Is shifts fine up the cassette but, when coming back down it has a problem. The derailleur cage isn’t moving to compensate for the extra chain in the bottom cogs. So there is a bunch of chain slack. But, I can move the cage by hand to the position it’s supposed to be in without much force. So I’m woundering why the derailleur wouldn’t be moving to pick up the tension on its own.

there is resistance in your cable housing. take the cable off the derailleur and shift all the way up/down a few times and add some grease to make things smooth. if it doesn't work, buy a new cable/housing set.

Just buy a new cable and housing assembly. It will save you lots of time.

there is a spring behind the cage, it often has 2 possible mounting points to adjust the tension on the chain.

if the cage has been removed it needs to be rotated on asssembly so it is under tension,

Sounds like you’re having a similar problem to one I had a few weeks ago. Depending on the derailleur you have (this happened to me on a Shimano XT M8000), i’d say your problem is a sticky clutch

Dissemble the clutch completely, clean and re-grease. This should solve your problem

Great, thanks for your replys. I'll try the solvents first. Thx

To clean and regresse a Shimano clutch do I need a special grease or would some park tool green stuff work fine?

Don't use that. Instead use something light like phil's oil or shimano internal hub grease.

Just ordered a Stans Flow S1 wheel and after ~40 miles the spokes seem loose. Wheel is still tru but does this seem normal? I’m hesitant to tighten them as my last wheel needed to be replaced due to overtightened spokes (granted the wheel was about 4 yrs old at that point).

Check the tension or have your lbs/wheelbuilder check the tension.

new wheels need tensioning after a while as the spokes bed in to the hub flange, not unusual
