Any question answered...

Overtightened cones?

Cartridge bearings. But I pulled it apart again, tried to seat everything again, added more oil to pawls, and reassembled - seems to be working now. Assume bearings will “settle in” and spin a bit easier after a few miles?

Forgot a thin washer/spacer between freehub and hub?

I thought that. Then I checked all the seals were the right way around. But I think it just needed to be taken apart, sworn at, dabbed with oil, and put back together again. The mechanical version of turning it off and on again.

The seals should bed in a bit, yes.

fusion 360 - i create a hexagonal polygon on a face, i then want to pattern this

but using the rectangular pattern wizard it wont let me select the hexagon. not sure of the Pattern Type - Faces, Bodies, Features or Components, but none seem to work

If the hexagon is a sketch object, you need to be in the sketch editor to create a sketch pattern

Right, got it thanks.

People who know things - can this be repaired?

Yes, by replacing the rim.

Doubt it. What's happened to the nipple washer? Zipps should have a thin oval washer between the nipple and the rim.

Bolt-on cogs on rear wheels...

If I have a standard 135mm rear with freehub and flip it around so the disk bolts are on the drive side, can I use this to make the bike fixed gear? Road chainline up-front.

Ish. The bolt-on sprocket is fine, the chainline will be way off, 54mm at the hub and 47mm at the crank for the outer ring of a road double.

Ouch, okay. Thanks.

Bolt-on cogs

This makes the pedant in me twitchy...

Depending on hub/sprocket combo you might be able to mount it on the inside instead of outside? Or machine down hub rotor bolt flange things. e.g.


look like they could be made to fit around each other... Disclaimer: only a fool like me would try something like this but I guess worth a go if you've got the bits handy.

Alternatively use a MTB triple crankset with two rings, middle for 1x and outer for fixed. I did this for about a week. You have to be a wizard to get the chain length right but with enough quick links it's possible to get both to work. If you had, say, 42/25 as your biggest gear the chain length will be close on fixed with 48/19 or something. Useful for some sort of freehub-died-in-Siberian-tundra apocalyptic backup where your alternatives are walking or death.

Am I making a sprocket/cog mistake?

Question; travelling to Buenos Aires in late December/early January is:

A) A shit idea as it is too hot, usually over 40'C, and everything interesting is closed.
B) An OK idea, as it is usually not hotter than 30'C, and only boring stuff is closed while bars and art galleries are open.

Not cycling related btw.

A simpler solution was more what I was thinking...

Looks like a surly hub, fixed/free is a better shout.

You could do it easily enough if you give up road chainline but yeah, probably better to just get a new hub

look like they could be made to fit around each other

Look again. The cutaway between the bolt holes needs to be a larger diameter than the threaded lugs on the hub shell, which is clearly not the case. Even if you kept filing until one passed the other, you'd not be able to get the bolts in, much less tighten them.

A simpler solution was more what I was thinking.

Have a look at your crank and chain ring and see if it would work with a set of 7mm spacers between ring and spider.

I knew "someone" would pick up on that. :)

There are ways of doing it if you really wanted to though. E.g. nuts to retain sprocket (I know, the bolt would loosen as you tighten the nut), removing material and using 3 or 4 bolts instead of all 6, cut the sprocket in half, get a bigger sprocket instead of that 16t, etc.

Pretty stupid though hence my comment that "only a fool like me would try this"

Edit: also maybe you could do centre-lock to 6-bolt with sprocket attached on reverse

Is this stem cap compatible to capo?

If you mean the headset bearing cover, then probably yes. Cannondale seem to cleave pretty closely to 47x2 for everything with a 1.125" upper
