Title: Strange behaviour with 12 year old Rohloff Thorne bike
Post by: swayzak on November 26, 2025, 10:28:28 PM

Hello

I have recently noticed that when changing to a lower gear (below 7), the gear fails to engage initially

This results in sudden loss of resistance when pedaling - so my feet suddenly lurch forward on the pedals

A bit disconcerting as often happens when changing down when starting an ascent

It is only momentary, but didn't used to happen

And idea what is causing this? Could the gear hub have developed a fault?

Thanks

Ive not experienced this behaviour before but suggest you go to the following link

https://www.rohloff.de/en/service/handbook/faqs

then go to
>trouble shooting>free spinning (after a gear change)

which might help. If not then refer problem to Rohloff/Rohloff dealer.

Gear change cable stretched a bit??
Check your chain tension too.
