Certainly could do with a clean!

This is strange, I google imaged the XTR M960 chainset and from the pictures that came up the none of the non-driveside crank arms have the locking plate pin thing (no.9) on the Shimano M960 pdf!
Is the compression bolt plastic or metal, if metal then I'm guessing that you do it up nice and tight, then the crank arm bolts and keep your fingers crossed!
Hi, crack on without the security tab. It serves no actual function once you have lightly tightened the preload plastic cap by hand. Any over zealous tightening will just ruin bearings. Do check your Bottom bracket is 68 or 73 mm and the correct spacer is there for 68. Do tighten each crank arm offside bolt alternatively with a torque wrench. I once just walked in one tight then the other and sheared a bolt. Be aware replacement rings will be an issue. They have a very odd BCD , a one off for Shimano .
This advice is spot on. The compression cap isn't holding the crank arm on, hand tight to engage the bearings is all you need here
Then all you have left is the 2 cinch bolts, tighten them alternatively and equally.
When it's off give it a good clean, looks like a small crack on the BB bearing cover, so possibly need a new BB in the not too distant future

I think I've tightened the arm bolts properly, left and right one crank at a time etc.
I can't see any cracks anywhere, might be shadows or general filth unless you can put an arrow where you can see?
I replaced the O ring, there was one there and sitting neatly into the arm but I have it a wipe down and the new one looks better.
The bolt I think is plastic, I've got a hand tool to tighten it so I haven't been aggressive. The bolt has a collared neck which seats into the arm so if it doesn't move I can't see how the arm can.
I could use my Dremel to notch something for the pin but I'm not overly keen on that.
It's all very complicated for my tiny mind...
Sounds like you've got it sorted.
No big deal re the BB, just if you use it in all weather you might get some crap in there over time

Checked the other photos I has taken and it's definitely not cracked, looks more like a scratch.
Ill keep an eye on it this week and worse case I'll cut a groove into it for the pin.
I'm doing serious speeds on it since the e-conversion so don't like anything feeling off.
Thanks for the advice all.
Morning, continuing to keep an eye on it daily until my paranoia subsides but it's not moved at all, so very happy. Thanks for the advice.
Chap in a builders van was belly laughing at me this week as a overtook him 👍
Sun was out yesterday, continuing to test the new one.
That Curtis, so good it stands up by itself. Lovely!

Morning all, looking for some accessory advice from those more experienced.
I use my bike every day to commute at road speed and am finding the wind noise is really starting to affect me when I get off the bike my ears are ringing.
I wear a Bell helmet with a spoiler peak but facing forward the wind noise is really annoying and I can't ride with my head tilted to the side all the time.
I don't want to use earplugs for obvious safety reasons, so can anyone offer up an option?
Was thinking maybe a windproof cap or head band to go under the helmet like this? I've tried a beanie but it made no difference.

Anyone got any ideas please?
Cheers.
Something like the Castelli Head Thingy is very flexible and can cover your neck, head however you want to arrange it, even as a balaclava. They come in thermal or lighter versions.
I use one of these caps in winter and I think they make the wind noise worse, I can defiantly hear less when I wear it ...
Maybe try a different design of helmet as it maybe the wind funnelling through the vents, maybe an easy test is to tape up the helmet vents to see how that works out??
You could maybe try these (reviews seem ok):

Motorcyclists have this issue a lot. So the ear plugs for them contain filters. These are like small tubes that penetrate the plug. They maybe an option in the summer when you dont want a bandana / buff etc covering your head and ears.
The trouble is to attenuate noise you need mass, thats why your beanie didnt work. Foam plugs of various density use mass and flexibility to dampen down the sound.
prob expensive solution but noise cancelling ear pods but not paired. Would they work? Or is it the helmet producing the noise? Not a thing I've experienced in 30+ yrs and 1000s of miles of cycling
A stunning day for a 20-mile leisure cycle from Dungeness to Folkestone, and then the bus back.
Even managed to get then wife along for the jounrey on the basis she has electron assistance.

My retirement/semi-retirement rig is set up. Good for buses, planes and trains.
My plan is for gentle touring in UK and Europe.

It's been great weather here, trails are dry and trees are green.
A little rant.
Yesterday I noticed a split in my front tyre, probably from a bit of glass. So today I ordered a direct replacement, a Specialized S-Works Mondo. £55! I seem to recall buying car tyres for less not that long back? Okay I'm definitely showing my age now, lol!
Can't complain though as I'm loving the bike and, more importantly, it's encouraging me to cycle more. Mainly because it's by far the most comfortable road bike I've ever ridden. It's a Trek Domane SL from about 2020. I'm more into my MTB's and road bikes are a means to keeping some semblance of fitness. However I haven't been out on my MTB since I bought the Domane!
Cheers,
Gary

I'm pretty much the same, was massively into MTB and bought a road bike to keep my fitness levels up, mountain bike hardly gets a look in now a days and I'm on to my 4th road bike.
I run tubless Continental GP5000 S TR tyres so feel your pain with the price if them!
Agreed tyre price is a joke, they have used the tubeless trend to push them up.
List on a GP5000 tubeless is £80.
Bit of a late reply to this, but - in my case I wanted to prevent wind noise from overcoming audiobooks and radio broadcasts. I found this product, called "Cat-Ears" on Amazon : https://www.amazon.co.uk/Cat-Ears-Ai...dp/B06VY6MH3Y/
However the price put me off so I reinvented them using cheap, fluffy wristbands plastic tied round my helmet strap. They looked fairly ridiculous but they worked really well. You can tell the difference they make by pulling them away from the side of your face for a moment in a headwind. It's dramatic.
Since then I've solved the problem by using earbuds that penetrate my ears a bit deeper.
