Hopefully this topic will not be well populated, but today I went for a ride on the Guvnor, off to a meeting actually. And not even halfway to my destination the back wheel locked up. Actually it first became a bit harder to pedal and then skidded to a standstill. I am fortunate to have the plus four (#21) so it’s the 2 gear Duomatic rear hub.  I was not in the act of switching gears, just pedaling. The whole contraption is now tight as a, well I won’t go there but needless to say the Guv is now in the back of Mrs. Seely’s car after she was kind enough to pick me up and deliver me to my meeting. She chuckled a bit on the way. No time at present to dive into the problem with spanners and the like but I was wondering if any other unfortunate sole or bright lad might tell me what I might be looking at (cause and effect).

Best,

Joanthan

Joanthan.….….……sorry to hear about the problem with your Plus Four. From what you’ve said it seems that the Sachs Duomatic internal brake cone is binding? Check out this website for technical and stripdown info.:   http://www.bicyclehub.co.uk    > Bicycle Gearing > Sachs Hub Gears.  

Warranty claim via the US Pashley agents, (other parts, 1 year from purchase.)?

Hope you get it sorted soon.

Safe rides? Geoff ‘DW’.

PS: have you received your wing nuts yet?

PPS: been having a look on the internet, there seems to be lots about the Sachs Duomatic hubs, but nothing specific on the problem  you are having! DW

Hello Jonathan,

perhaps this link could be helpful to you: http://hubstripping.wordpress.…..omatic-fs/

The people there also seem to be experienced as regards to geared hubs, so you might find some help there.

Keeping my fingers crossed, that your problem will be solved soon.

Kind regards,

Hartwig

Jonathan,

I’ve been reading some of the web sites regarding the Sachs Duomatic.  Just a thought, but might the problem be lack of lubrication to the unit, perversely the brake components require oil to function correctly.

Metal + metal + friction = heat - lub = seizure!

Safe rides one and all, Geoff.

Jonathan ‘jseely’.….…any update on the your seized Sachs Duomatic rear hub? 

Jonathan,

Not a very satisfactory outcome so far! Maybe you could contact Pashley direct, to see if they will offer some goodwill assistance. After all, the hub did fail after an unreasonably short service period and Pashley must bear some responsibility in the matter.

They did source and fit these new old stock hubs and presumably they were thoroughly checked/serviced before being used on a new cycle, in fact it would have been negligent of them not to have done so.

I recall you purchased your Plus Four from Evans in the UK, under UK consumer law your redress is with the retailer. It may be worth contacting them, they will probably wriggle because it was exported to the US, but it might be worth a go!

Safe rides One & All. 

Chaps, is there any quick and easy way of sorting a wobbly back wheel out? I took a hit this morning and have developed a slight wobble. It’s not too bad, but I’d rather get it sorted if theres a simple way.

Planning to put the Guv in for a yearly service soon anyway, so perhaps best to wait for that?

It’s probably a simple job, so I’ll have a root around youtube. Could have been a lot worse considering the truck that wnt into me

Thanks
