New Chain Skips On Freewheel

Yes, thanks to you and the others, this bike has been repaired, test ridden and is ready to ride.
Yesterday, I installed a new chain and an almost new, 5 speed Dura Ace freewheel (14-16-18-20-22T).
It didn't take long to do. I spent more time disassembling the freewheel and marvelling over the broken cog than the repair.
As P!N20 said, "Too much power".

@Bad LagYou often have to change the chain and freewheel together. < > The wear may not be visible, but it's there.
I guess I was lucky this year changing stuff on my MB. Did the FW first but nothing else, got away with it OK only to learn I needed to go further with changing stuff to gain the gearing advantage I was seeking.
Ended up swapping crankset (eBay / needed smaller inside ring), chain rings (ended up with three), BB (VeloOrange cassette vs. cup & balls), rear derailer too (donor bike / longer cage), plus a new chain.
Chain was the least $$ bit. (I don't get paid for my time invested in the work either, save for the benefit of the experience and performance once it's all done.)
Never looked back once I tried it all, it simply works!

I'd guess that most of us who spent years working in shops as bike mechanics read the opening post and knew that (a) the problem was, as usual, new chain/old freewheel and (b) the OP and many subsequent posters would come up a dozen alternative theories (some more plausible than others, to put it delicately). This thread ran a bit longer than most "but the freewheel looks fine" threads, though, so it was pretty entertaining.

I should add that it is sometimes possible to change the chain alone. I change mine frequently to avoid wearing out my cogs. By "wasting" chains (replacing them before they're fully worn), I can go through approximately three chains before I have to change my cassette.
I'm glad to hear the bike works well and that we've been able to help.

In fact, on the bikes that get the bulk of my miles, I will actually rotate between three chains so they wear at the same rate as the cassette. This might be a bit too attention to a small detail, but it seems like a better idea than throwing a new chain onto a cassette with 1/3 of its life remaining. It does require actually keeping track of the chains so they stay in the rotation sequence, though.
I pull my chains off for cleaning and lube every 500 miles, which is when I swap to the next chain in the sequence.
Drive train wear is one of those things that is slow and progressive, and it's easy to ignore until it's no longer possible. All of us eventually learn the subtle details of what wears first and what the symptoms are.

@steelbikeguy, yes, that's too complicated BUT I did accidentally buy two chains so maybe I'll do that. I generally avoid cleaning chains, as I find it to be unrewarding, but maybe I'll take this one off, clean it, store it, and install the other one. Keeping track of the miles or months is another complication. Thanks for the idea.

I've spent the last month focused on the drive train while riding. It was either the broken crank, the replacement crank, the noises, the grinding, the freewheel or the chain. .
The recent rides are nice and quiet now - no grinding; no slippage; super-fast, unambiguous shifting. I can get back to enjoying the scenery.
I may buy another one of these IZUMI chains just to have it on hand. I also need to get some spare freewheel cogs and set those aside, too.

The purists here won't like reading this, but I've converted all of my derailleur bikes to cassette hubs. They are better in many ways. Axles don't break, and it's easier to get cassettes than cogs for freewheels.

The wheels I am riding are almost 40 years old - MAVIC MA2 rims on Performance Bike sealed bearing hubs. They remain rock solid but it is just a matter of time.
I have some VO rims in the rafters, waiting. I have sets of Record and 1st Gen Dura-Ace hubs, waiting.
This bike is and will remain 120 mm spacing with a 5 speed freewheel.
As heavy as I am, I have never broken an axle. (knocks on wood).
P.S. - I am really liking the all-new drive train and am quickly regaining my confidence in it. It is smooth-shifting and runs quietly.

Much the Same Here
51+ on my MAVIC rims -
Wired to Campy Record wide-flange 36h hubs front & back, ball & cap still (but with new bearings this last spring). Have a pair of eBay'd Ukai 19mm clincher rims sitting idle, waiting to be wired to an identical pair of Campy hubs (eBay'd again) so I can try riding on clinchers next season. Don't ride that Kona I bought last April much, the MB GR is vastly more fun & 12 pounds lighter.
Same here though I futzed with the gearing front & back this year. Stock 2x5 (din't work where I ride now, once I got back on the saddle after over ten+ years lapse) changed to 3x5 with a VO BB cassette & Stronglite 93 crankset.[/QUOTE]
Seems from your OP there's other bits in your drivetrain that may be less up to the challenge?
My personal gremlins are lack of habituation (to getting out and riding), shortish riding season (it's 10°F outside as I key this in) and a bit of Arthur Itis showing his face the last few months.
Same here. Season slammed shut too soon for me to get many miles done but what few I managed proved the worth of the various upgrades. Looking forward to warmer weather's returning in a few months.

The good news is, my tires and brakes are wearing out. <-- That's my attempt at a humor, a way of saying I am riding a lot. It is 70 degrees and sunny here, today, with a beautiful on-shore breeze.

I've been riding with the new chain and freewheel for a month now.
The new IZUMI chain has been great! This chain is so quiet, I'm not sure I've ever had one so quiet before.
It is so quiet, it is almost a problem because you cannot even hear it shift (but I'm not complaining). There's no "snick" or "chunk".
I'm wondering what the lube is. It seems very viscous, almost like 90W gear oil. It certainly smelled like a petroleum product.
That $25 was well spent. I also ordered a spare, as this one will eventually wear out.
Thanks for all the help and guidance, especially to Fried Chicken for the suggestion of an IZUMI chain. It has worked out well.
I'm heading out for a ride soon.

I've been taking advantage of some occupational therapy for arthritis in my left thumb. Tech suggested a hot wax 'bath' (paraffin @ 125°F) which I found really messy but helpful in relieving the pain after a day at work.
Messy though, so I may save the thing I bought off Amazon for $45 for waxing chains instead. Hot water bath (for my hand, in a 2 qt measuring cup) works just as well, isn't nearly as messy. Save the wax for bike chains next year.

Interesting. The Izumi 410 series site says it's only available in 1/8".

Their naming conventions are confusing. Here it says the ES410C is for 5-6 speed clusters:
https://medium.com/@IZUMICHAIN_1916/...n-77507c8e0c67
It's a bushing chain that weighs about 80 grams more than a KMC X8.

410C
from $20.99
All the style and durability of the 410 in a chain made for 5-6 speed bicycles. Pick the striking Jet Black/Silver finish for style, or the Silver 410CNP for exceptional rust resistance even when used in the nastiest urban riding conditions.
Available in 1/2x3/32 width only
362g (116 links)
Select the chain that is right for you from the 410C series
410C - The Original
410C_JB-S - Jet Black/Silver
410CNP - Silver, Exceptional Rust Resistance
The package is correctly labeled as 1/2" X 3/32" but the 410C code does not appear. Also, the ES410C I was originally given appears to be incorrect, so I edited my post, above.
