That all makes sense, but breaking the chain in two places, creating two,
separate, bits of chain? Wouldn’t the first break have been enough the relieve
the tension? Oh well. Quickbeam is all set for a (brain willing) longerish ride
tomorrow. That’ll be right proper fixing. No more of the poser
I've broken two chains and it is one of the most abrupt and exciting things
that can happen going slowly. Thanks for sharing!

I think Philip has it right. The chainline was off and the chain was
essentially trying to get in line with the chainring. Climbing flexed the
frame, decreased the distance between the bb and cassette, and created some
slack (less tension) in the chain. The chain shifted (helped by the shape of
That could well be, Philip. Balrog sized hobbits’ll do that sometimes. Grin. My
takeaway matches Kai’s thought: I’ll stick with dedicated fixed gear bits for
fixed gear riding (initial 20 miles of fixed riding today — amazing. Brain
willing more tomorrow, including more technical trail.).

Something weird happened that you don't want to happen again. My guess is
now that your massive hobbit wattage while powering up that climb deflected
the bottom bracket out of plane enough to shift to the unshiftable cog.

Kai, that is my experience as well, that close enough is close enough with
dedicated ss/fixed set up with cross chaining on my QB (albeit that is highly
dialed in by Grant already).
Bill, 3/32”, aye. My typest is a wee bit daft in the head sometimes. Grin.

A 1/32” chain would be pretty narrow #sardonic grin

I've been told that modern chains needn't be "spot on" to be perfectly fine
on a single speed. Not sure if this advice carries over to an improvised
multi to single speed set up, but with dedicated single speed/track stuff,
close enough is good enough. At least that's what I was told after
agon
Yea, chainline was my first thought, but I dismissed it as it was one cog up/in
from center and the middle chain ring. I’d eyeballed it before riding and
thought it looked alright, but I’m far from an expert.
Is 1/8 chain stronger than 1/32? I’d understood they were the same.

Deacon P,
Sounds like you chose a cog on your cassette that was outboard of the
position of your chainring in front, so the chainline itself was acting
like a derailer trying to shift you into a bigger (inner) rear cog, which
the chain was too short to accommodate and which your legs were plen
Well gee . . . I laugh with you DP ! I've done my share of wacky things
with a bike too.
I don't own or ride a SS and never have even seen one, but just picturing
what you describe I can see why you had no chance.
For SS, the chainline must be spot on(same plane if you will), if it is
n
Sounds like your chain line was bad? Small ring, maybe, and a middlin' cog?
The larger cog caught the chain and levered it up and apart. Same chain
length and a single cog in the right location should be fine.
I use 9sp chains on my single/dingle/fixed bikes, and once I learned you
can't use a
Step 3 often applies, and can be serious. Fortunately, at step 7 you've
got the whole thing in perspective.
Maybe this is why single speeds us a much wider chain than 6/7/8?

I may be wrong, Philip, but I think the error was in #2, using the cassette
without a derailer. The chain attempted to shift to a larger cog. Pop! No idea
why the Pow! happened though. Sardonic grin.

All that sounds fine, up until 4b.
I've done similar by putting a nine speed chain back together with a chain
tool instead of a master link.

What could be better than a near disaster turned into a good story.
