Not sure what buckled means.

I suspect that I can't offer a valid opinion early enough to help if you are at work right now.  I assume you are six or more time zones east of me.  And this may be too late.

But, I will throw in my two cents worth.  Ride slow, avoid bumps, do not pedal hard which could put more torque on the hub.

If it is disc brake, don't use the rear brake unless you really need to.  That also puts torque on the hub.  But rim brakes do not put much additional stress on the spokes.

But if your rim damage looks bad, then maybe not.

Hello

Got to work today on my old Marin MB and noticed 2 snapped rear spokes, and quite marked buckling of the rim

Still spins without rubbing anything and the hydraulic brakes to working

Difficult to be certain I know, but would this be safe to ride 6 or 7 miles to my local bike shop? Or should I get an uber home & take it in the car tomorrow?

Thanks

That "avalanche shed" photo is amazing as a composition, architecturally and as a mystery to be solved.

Architecturally the avalanche shed is "merely" a regular repetition of massive pillars with a featureless wall and roof enclosing a floor and an emptiness, but there is a certain brutal charm in such spectacular simplicity, and of course there are the shadows to define the shapes and provide movement, hinting in the momentary snapshot at the passage of time. But then there is the inversion of shadows across the roof, which raises questions.

The mystery: Surely the sun can't be so much lower than this covered road. What, to the left, is so reflective that it lights up the inner wall and the ceiling of the avalanche shed?* It's the sea, of course, of which the tiniest sliver is seen at the far left of the photo, used by the architect as a player in the spectacle.

You've outdone yourself, Ron.

* Yes, I know, Ron provides the answer. I read it before I enlarged the photograph.

However whilst investigating this I stupidly put the shifter in gear 1 (not 14) before detaching the ex-box and cleaning it a bit

Now it won't reattach properly - how do I realign things to gear 14 so I can attach it back correctly?

You need an 8mm box spanner or a socket that fits whatever driver you carry in your toolkit. Take the EXT box off and let it hang on the cables. Identify a nut, brass if I recollect correctly, in the centre of the hub. Turn the nut on the hub in either direction with the socket until it will turn no more. Turn the rotary gear control on the handlebars to gear 14. Pack grease into the cavity on the EXT box. Try to fit the EXT box back on the hub while wriggling the rotary control on the handlebars a very little way, not enough to change gear. If it is difficult to match them, or if you can get it on and discover the rotary control offers you only one gear, take the EXT box off again, turn the nut on the hub in the other direction until it stops, and try to fit the EXT box again and test it. A successful match has 13 clicks over the full 14 gear set.

In theory you can also do the matching at gear 1 but it is so much more difficult that I prefer to do it at gear 14, as just described. Still in theory, you can also perform the matching at any other gear, but the math is another confusing factor. I prefer simplifying tasks to their easiest, fastest execution.

You may want to carry the 8mm socket in your traveling kit because it permits you to change gears if you should break a gear cable and not want to refit it beside the road. My entire traveling toolkit weighs 68gr including this 8mm socket with an integral stud on the back to fit my titanium driver, so it isn't a hardship to include it.

Hi,

Perhaps the Son 28 was not at fault, we will never know as they didn't mention anything when the hub was returned fixed under warranty.

What I can say is that there was no chemical sprayed on the hub. The only thing I did, which I shouldn't have, was lightly grease the QR.

A friend also had their SON 28 fail after about 15,000KM, currently under repair.

Glad you managed to repair your unit.
