Changing cassette and chainring size - other adjustments needed?

I'm changing my cassette and chainring (actually the whole crank) on my bike. The bike previously was on 52/36 up front and 11-28 on the back.

To gear down for an upcoming everesting, I'll be switching to a 50/34 and 11-32.

I know I need to make sure my rear derailleur has a long enough cage for an 11-32 cassette, but are there other adjustments I need to make, or should consider making? I'm primarily thinking front derailleur height (check, but will likely need to drop it down) and chain length (check it per https://www.parktool.com/blog/repair-help/chain-length-sizing).

Do I need to worry about those 2 things? Are there other things to check that I haven't considered?

You'll be fine with all that. Adjust the limiter bolt for the bigger cassette if anything

if you getting new cogs front and back best to get a new chain as old chain will have worn with old cogs and you could get slippage - also if going to smaller chainrings you might want to lower front mech for optimal shifting - probably can get away with no doing it though

Oh cool. I'll give it a test ride this morning then as it is to see if I can get away with it.

I want the shifting to be as good as it can be, but it'd be ideal if I don't need to adjust, as I'll be doing 1 big ride with the bike as it is, but then switching back to the semi-compact chainset and 11-28 cassette. All of the components (chain, chainrings, cassette) have very little wear, so no worries there.

Quick update in case anyone else has a similar question in the future - the front derailleur seems to be fine (visually it's a little high, but shifting quality still seems very good), however the chain was extremely tight in the largest cog and chainring combination. I made a decision to switch to a chain with 1 extra link, and am much happier with that now.

You should change the chain anyways, new drivetrain will work better with a chain that's not elongated

I know, but the previous chain had only done around 50km. Stuck it in a bag and I'll put it back on when I change back to my normal gearing.

Might need to adjust the B screw on the rear derailleur so that the top jockey wheel doesn’t interfere with the 32t cog

What’s the hill of choice?
How long are you expecting it to take you?

Kop Hill near Princes Risborough. Realistic estimate is 17.5 hours. Best case 15 hours, worst case 20 (or not finishing). Training has gone well so far, though, I've done up to 5,600 m of ascent in one ride, so feeling fairly optimistic!

Sounds promising.
Blimey looks quite steep at parts. What made you choose it?

Haha yes, I've had a few people tell me it's far too steep! Main reasons for my choice were logistics (my father lives close by so somewhere to sleep before and after), volume of traffic (it's the quietest road up that ridge that I know of for motor traffic), and descent quality (silky smooth tarmac, well sighted, and wide, so no need to touch the brakes).

Have you everested before, or are you considering one?

Fair enough. What date are you attempting it? Will you be the first on it?
It’s something that is loosely on my radar. I like the banality of it. Also appeals as you can do it in a day...

Looks like you’ll be in esteemed company;

May 25 if the weather is good. If you ever decide to do it, feel free to give me a shout if you'd like any advice. I also started writing a blog about my training and planning as I'd found it tricky to find good information about certain aspects of it.

I’d be up for reading it
