Has anyone had problems with this?
The little rivetted "noggin" that sticks out and engages in thelower part of the dropout to stop rotation has broken off. When I got a replacement (thank you SJS - very quick postal service) I saw the whole of the lower portion of the flat metal plate was twisted slightly. This indicates to me that a rotational force has been applied to the "noggin" over a period of time.
I've always been nervous of overtightening the quick release as per instructions. Am I worrying unneccessarily about causing damage or do I risk greater damage by over-tightening the QR?
Any thoughts?
Thanks
Jim

Hi, this was picked up as an issue and Rohloff responded by making the part from one bit of metal rather than rivetting http://www.sjscycles.co.uk/rohloff-aftermarket-to-oem-axle-plate-converter-mkii-for-qr-hub-8234-prod10454/
It usualy only occurs on bikes running under a 2.5 imput ratio, or where the axle plate has been hit when the wheel has been removed, or if the bike is ridden with the skewer loose.

Grrr... Wish I'd known that before I ordered the replacement. Oh well.
The bike is not under the permitted ratio (I'm running 42x16) but I'm a big lad and its on a mountain bike that does have quite a hard life on the hills of the Peak District. I figure it'll eventually break again and I'll order the right one next time.

Jim, is it on a Thorn bike, or a hub we sold you?

No it got the hub from a well known online auction site. But, I did buy all the shifter bits and brake disc etc from you guys ;)
The bike is a Dave Yates full custom built MTB, because you guys weren't too happy about my size and weight on your bikes (six feet five and eighteen stone). Dave built me a made to measure frame from tandem guage 853 with a full compliment of Rohloff fittings. There are photo's of it in the snow on Dave's website if you want to see it.
I can't tell you how nice it is to ride a bike that fits after nearly twenty years on a variety of slightly too small frames with 400mmor 450mm seatposts. And the Rohloff works so well in the mud and grit of the Peak District.
