Never seen jockey wheels like this before....

[smokeysmoo]

A guy at work recently bought an old Holdsworth and has restored it in THESE colours, and I have to say it looks a million dollars.

We were talking the other day and he asked if I'd ever seen jockey wheels with no teeth on. I said only on knackered jockey wheels! Then he showed me the Huret mech he'd stripped off this Holdsworth.

I've never seen one before, and it's safe to say it didn't catch on. It has a slightly weird chain also with larger plates, presumably to stop it coming off the jockeys as it passes through.

Anyone seen these before and maybe shed some light on their proposed benefit, or as I suspect were they just a design fad that proved pointless in the long run?

Normal chain - just old.

Many mechs were like that years ago, even the Campag stuff only had very small indentations rather that teeth.

I've never seen them before but immediately found a picture of one with a completely flat lower wheel. Were both the wheels the same on your workmate's dérailleur? I suppose there's little stress on the lower one as it's only acting as a guide but it doesn't seem worth engineering a separate toothless wheel.

Yeah they were both the same.

Yeah they were both the same.

It's not a Huret Jubilee then - they appear to have had a toothed-toothless combination.

Lots of recumbents use toothless rollers.

Don't you mean lots of toothless rollers ride recumbents?

Takes me back, red Huret jockey wheels. Not seen them for donkeys' years. They used to be common place in the 70s.

My first real bike "a racer" in the 70's had the same jockey wheels and never gave any trouble at all even after a teenagers gearcrunching.That was a huret gear system.
